[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] See also Figure 1 , Figure 1 This is a flow chart of a method for sending instructions provided by an embodiment of the present application. Figure 1 As shown, the following steps are included:

[0034] Step 101: The target server obtains a first operation instruction.

[0035] The first operation instruction may be an operation instruction input by an operator based on configuration and change requirements. For example, the first operation instruction may instruct an operation such as adding, deleting, or modifying an operation object. It is understood that after receiving the first operation instruction, the target server may first invoke a syntax check function to perform a syntax check on the first operation instruction. After the syntax check passes, subsequent steps may be executed to ensure the correctness of the syntax of the first operation instruction.

[0036] Step 102: The target server generates a second operation instruction based on the first operation instruction.

[0037] It is understood that the second operation instruction may include the first operation instruction, that is, the second operation instruction may instruct to perform an operation such as addition, deletion, or modification consistent with the first operation instruction. The second operation instruction may be generated based on the first operation instruction by directly adding the content of the first operation instruction to the second operation instruction, or by generating an instruction including the content of the first operation instruction as the second operation instruction.

[0038] Optionally, in step 102, the target server generates a second operation instruction based on the first operation instruction, which may specifically include the following steps:

[0039] The target server obtains the execution status of the script;

[0040] Based on the execution state of the script, the target server generates the second operation instruction using the first operation instruction;

[0041] The second operation instruction is used to instruct the slave server to execute the target operation and the script on the target operation object for a certain number of times and in a certain order.

[0042] Among them, the above-mentioned script can be the script that the above-mentioned second operation instruction instructs the above-mentioned slave server to execute, and the above-mentioned script can be included in the above-mentioned second operation instruction. If the above-mentioned slave server is instructed to execute the above-mentioned script before executing the above-mentioned target operation, the first parameter information of the above-mentioned target operation object can be obtained; if the above-mentioned slave server is instructed to execute the above-mentioned script after executing the above-mentioned target operation, the second parameter information and alarm information of the above-mentioned target operation object can be obtained.

[0043] It can be understood that the above-mentioned slave server can be a slave in a master-slave hot standby mechanism established between the master server and the slave server, and data synchronization between the slave server and the master server is achieved through the master-slave hot standby mechanism.

[0044] Among them, the execution state of the above-mentioned script can be a certain execution state confirmed in the pre-set execution state. For example, the execution states of multiple scripts can be pre-set, and the conditions to be met can be pre-set for each execution state. The above-mentioned slave server determines the current execution state of the above-mentioned script by judging the pre-set conditions to be met. Based on the execution state of the above-mentioned script, the current operating state of the above-mentioned slave server can be obtained, and the master-slave hot standby mechanism is formed between the above-mentioned slave server and the master server. The current operating state of the above-mentioned slave server is the operating state of the above-mentioned master server. For different execution states of the scripts in the above-mentioned slave server, the order between the execution of the above-mentioned target operation and the above-mentioned script by the above-mentioned slave server, as well as the number of times the above-mentioned script is executed, can be adjusted accordingly to obtain the above-mentioned first parameter information, the above-mentioned second parameter information and the above-mentioned alarm information.

[0045] In this embodiment, based on the execution status of the script, the target server uses the first operation instruction to generate the second operation instruction, wherein the second operation instruction is used to instruct the slave server to execute the target operation and the script on the target operation object the number of times and the order. The number of times and the order in which the slave server executes the target operation and the script on the target operation object can be adjusted accordingly according to the different execution statuses of the script to obtain the first parameter information, the second parameter information and the alarm information under different execution statuses.

[0046] Optionally, the target server obtains the execution status of the script, which may specifically include:

[0047] The target server obtains the execution times of the script and the change information of the control right of the main server;

[0048] The target server determines the execution status of the script based on the number of executions of the script and the change information of the control right of the main server.

[0049] Specifically, taking the execution status of the above-mentioned script as an example, which is pre-divided into three states: initial operation state, system migration state and normal operation state, the conditions that need to be met in the above-mentioned initial operation state can be set as: the number of executions of the above-mentioned script is 0 and the control right of the above-mentioned main server has not changed, that is, in the initial operation state, the above-mentioned script has not been executed and the system has not migrated; the conditions that need to be met in the above-mentioned system migration state are set as: the control right of the above-mentioned main server has changed, that is, the above-mentioned system has migrated; the conditions that need to be met in the above-mentioned normal operation state are set as: the number of executions of the above-mentioned script is greater than 0 and the control right of the above-mentioned main server has not changed, that is, the system has not migrated and the above-mentioned script has been executed.

[0050] In this embodiment, the slave server can determine the execution status of the script based on the number of executions of the script and the change information of the control right of the master server, thereby adjusting the number and order of the slave server executing the target operation and the script on the target operation object accordingly.

[0051] Step 103: The target server instructs the slave server to perform a target operation and a script on the target operation object based on the second operation instruction, so as to obtain the first parameter information of the target operation object before the slave server performs the target operation, and the second parameter information and alarm information of the target operation object after the slave server performs the target operation.

[0052] In some embodiments, the target server and the slave server may be two independent servers. After obtaining the first operation instruction, the target server generates a second operation instruction and sends it to the slave server to instruct the slave server to perform the target operation and script on the target operation object, and then determines whether to send the first operation instruction to the master server based on the execution result of the target operation in the slave server.

[0053] As another embodiment, the target server and the slave server may be the same server. For example, in the case of resource scarcity, the slave server may act as the target server to execute the instruction sending method. The slave server directly obtains the first operation instruction, generates the second operation instruction, and executes the second operation instruction, thereby obtaining the execution result of the target operation in the slave server. It can be understood that the process of instructing the slave server to indicate the target operation and the script to the target operation object is to execute the code implementation inside the slave server.

[0054] Determine whether to send the first operation instruction to the main server to improve resource utilization.

[0055] It can be understood that the above-mentioned second operation instruction can be used to instruct the execution of the target operation on the above-mentioned target operation object, and the above-mentioned script can be used to obtain the parameter information of the above-mentioned target operation object. For example: before the above-mentioned slave server executes the above-mentioned target operation on the above-mentioned target operation object, the above-mentioned script is executed to obtain the first parameter information of the above-mentioned target operation object before executing the target operation; after the above-mentioned slave server executes the above-mentioned target operation object, the above-mentioned script is executed to obtain the second parameter information and alarm information of the above-mentioned target operation object after executing the target operation.

[0056] Optionally, the field content of the warning information is determined based on the operation type of the target operation;

[0057] Before the target server instructs the slave server to perform the target operation and the script on the target operation object based on the second operation instruction in step 103, the method further includes:

[0058] The target server obtains the operation type of the target operation.

[0059] Among them, the above-mentioned alarm information can correspond one-to-one to the operation type of the above-mentioned target operation. For example: when the above-mentioned target operation is to add data, the field content of the above-mentioned alarm information can include "add data"; when the above-mentioned target operation is to delete data, the field content of the above-mentioned alarm information can include "delete data"; when the above-mentioned target operation is to modify data, the field content of the above-mentioned alarm information can include "modify data".

[0060] In this embodiment, the field content of the alarm information is determined based on the operation type of the target operation. In this way, when judging the execution result of the operation instruction, the operation type of the target operation can be used as a judgment criterion to determine the operation type of the target operation in the form of alarm information.

[0061] Step 104: The target server obtains the first parameter information, the second parameter information, and the alarm information, wherein the first parameter information, the second parameter information, and the alarm information are used to determine whether the execution result of the target operation is correct.

[0062] The execution result of the target operation can be obtained based on the first parameter information, the second parameter information, and the alarm information. Specifically, by comparing the changes between the first parameter information and the second parameter information, the impact of the execution of the operation instruction on the execution of the business in the server can also be judged based on the alarm information, thereby comprehensively judging whether the execution result of the operation instruction is correct. In addition, the judgment on whether the execution result of the operation instruction is correct can be judged by the operator. After the operator determines, the judgment on whether the execution result of the operation instruction is correct is input to the target server; alternatively, the target server or other device can also judge whether the execution result of the target operation is correct based on the first parameter information, the second parameter information, and the alarm information. The target server executes corresponding steps to judge whether the execution result of the operation instruction is correct.

[0063] Step 105: If the execution result is correct, the target server sends the first operation instruction to the main server, where the first operation instruction is used to instruct the main server to perform the target operation on the target operation object.

[0064] By determining whether the execution result of the target operation is correct, it can be determined whether the operation instruction contains incorrect configuration or changes. If the operation instruction contains incorrect configuration or changes, it may cause service errors and business interruptions on the master server. If the execution result is correct, executing the operation instruction can reduce service errors and business interruptions. After the master server completes execution of the operation instruction, the master server's data can be backed up to the slave server through the master-slave hot standby mechanism, achieving synchronous update of the slave server's data environment.

[0065] Furthermore, if the execution result is incorrect, the first operation instruction may be deemed to contain incorrect configuration and change content, and a new operation instruction may need to be obtained to implement the target operation on the target operation object. Specifically, the target server will not send the first operation instruction to the master server, and the master server will not execute the first operation instruction. Furthermore, the slave server may back up the data on the master server to the slave server according to the master-slave hot standby mechanism, restoring the data environment of the slave server to the state before the second operation instruction was executed.

[0066] In an embodiment of the present application, the target server obtains a first operation instruction; generates a second operation instruction based on the first operation instruction; instructs the slave server to perform a target operation and a script on the target operation object based on the second operation instruction, so as to obtain the first parameter information of the target operation object before the slave server performs the target operation, and the second parameter information and alarm information of the target operation object after the slave server performs the target operation; obtains the first parameter information, the second parameter information and the alarm information, wherein the first parameter information, the second parameter information and the alarm information are used to determine whether the execution result of the target operation is correct; if the execution result is correct, sends the first operation instruction to the master The first operation instruction is used to instruct the main server to perform the target operation on the target operation object; that is, the target operation performed by the main server is pre-executed by the slave server, and when the target server determines that the execution result of the target operation is correct, the target server sends it to the main server to realize the main server's execution of the first operation instruction. The first operation instruction can be executed in the slave server to obtain the execution result of the target operation, which can avoid the first operation instruction with erroneous configuration and change content from being executed by the main server, thereby improving the correctness of the service and business continuity in the main server, and improving the security of the main server in executing the operation instruction.

[0067] Optionally, the execution state of the script includes a first state, a second state and a third state;

[0068] When the execution state of the script is the first state, the second operation instruction is used to instruct the slave server to execute the script, the target operation, and the script in sequence;

[0069] In step 104, the target server obtains the first parameter information, the second parameter information, and the alarm information, which may specifically include the following steps:

[0070] The target server obtains the first parameter information obtained by the slave server executing the script before executing the target operation;

[0071] The target server writes the first parameter information into a first data table;

[0072] The target server obtains the second parameter information and the alarm information obtained by the slave server executing the script after executing the target operation;

[0073] The target server updates the second data table based on the first parameter information in the first data table;

[0074] The target server updates the first data table based on the second parameter information and the alarm information.

[0075] In some embodiments, the first data table may store parameter information and alarm information for the target operation object in the current state, and the second data table may store parameter information for the target operation object in the state before the current state. That is, the parameter information for the target operation object may be updated in real time via the second data table and the first data table. Furthermore, each operation object in the resource library of the target server corresponds to a second data table and a first data table to store changes in parameter information for each operation object between the current state and the previous state, as well as alarm information corresponding to the parameter information in the current state.

[0076] Among them, the above-mentioned first state may correspond to the above-mentioned initial operation state, the above-mentioned second state may correspond to the system migration state, and the above-mentioned third state may correspond to the normal operation state. The process of judging the execution state of the script is not repeated here.

[0077] When the execution state of the script is the first state, before executing the target operation, the slave server can be instructed to execute the script first, so that the first parameter information of the target operation object before executing the target operation can be obtained. Before executing the target operation, the first parameter information is the current state data, and thus the first data table can be used for storage. Then, the slave server can execute the target operation and the script in sequence, and the second parameter information and the corresponding warning information of the target operation object after executing the target operation are obtained by executing the script. After executing the target operation, the second parameter information is the current state data, and the first parameter information is the previous state data. The first parameter information in the first data table can be written to the second data table, and then the second parameter information and the corresponding warning information can be used to update the first data table. It can be understood that the first state is the initial operation state. When the execution state of the script is the first state, the script has not been executed, and the second data table and the first data table are both empty tables.

[0078] In this embodiment, when the script execution state is the first state, the target server obtains the first parameter information obtained by the slave server executing the script before executing the target operation; the target server updates the first data table based on the first parameter information and deletes information in the second data table; the target server obtains the second parameter information and the warning information obtained by the slave server executing the script before executing the target operation; the target server updates the second data table based on the first parameter information in the first data table; and the target server updates the first data table based on the second parameter information and the warning information. Thus, when the script execution state is the first state, the first parameter information, the second parameter information, and the warning information are obtained.

[0079] Optionally, when the execution state of the script is the second state, the second operation instruction is used to instruct the slave server to execute the script, the target operation and the script in sequence;

[0080] In step 104, the target server obtains the first parameter information, the second parameter information, and the alarm information, which may specifically include the following steps:

[0081] The target server obtains the first parameter information obtained by the slave server executing the script before executing the target operation;

[0082] The target server updates the first data table based on the first parameter information and deletes the information in the second data table;

[0083] The target server obtains the second parameter information and the warning information obtained by the slave server executing the script before executing the target operation;

[0084] The target server updates the second data table based on the first parameter information in the first data table;

[0085] The target server updates the first data table based on the second parameter information and the alarm information.

[0086] When the execution state of the script is the second state, before executing the target operation, the slave server can first execute the script, so that the first parameter information of the target operation object before executing the target operation can be obtained. Before executing the target operation, the first parameter information is the current state data, so the first parameter information can be used to update the first data table. However, since the control right of the master server changes in the second state, the information in the second data table is not the previous state data, and the information in the second data table can be deleted. Then, the slave server can execute the target operation and the script in sequence, and the second parameter information and corresponding alarm information of the target operation object after executing the script are obtained. After executing the target operation, the second parameter information is the current state data and the first parameter information is the previous state data. The first parameter information in the first data table can be written to the second data table, and then the second parameter information and the corresponding alarm information can be used to update the first data table.

[0087] In this embodiment, when the script execution state is the second state, the target server obtains the first parameter information obtained by the slave server executing the script before executing the target operation; the target server updates the first data table based on the first parameter information and deletes information in the second data table; the target server obtains the second parameter information and the warning information obtained by the slave server executing the script before executing the target operation; the target server updates the second data table based on the first parameter information in the first data table; and the target server updates the first data table based on the second parameter information and the warning information. Thus, when the script execution state is the second state, the first parameter information, the second parameter information, and the warning information are obtained.

[0088] Optionally, when the execution state of the script is the third state, the second operation instruction is used to instruct the slave server to execute the target operation and the script in sequence;

[0089] In step 104, the target server obtains the first parameter information, the second parameter information, and the alarm information, which may specifically include the following steps:

[0090] The target server obtains the first parameter information based on the first data table;

[0091] The target server updates the second data table based on the first parameter information;

[0092] The target server obtains the second parameter information and the alarm information obtained by the slave server executing the script after executing the target operation;

[0093] The target server updates the first data table based on the second parameter information and the alarm information.

[0094] When the execution state of the script is the third state, the slave server is in a normal operating state, and thus both the second data table and the first data table store the previous state data and the current state data under the current normal operating state. The slave server can sequentially execute the target operation and the script, and what is obtained by executing the script is the second parameter information and the corresponding alarm information of the target operation object after the target operation is executed. After the target operation is executed, the second parameter information is the current state data, and the information in the first data table is the first parameter information. The first parameter information in the first data table can be used to update the second data table, and then the second parameter information and the corresponding alarm information can be used to update the first data table.

[0095] In this embodiment, when the script execution state is the third state, the target server obtains the first parameter information based on the first data table; the target server updates the second data table based on the first parameter information; the target server obtains the second parameter information and the warning information obtained by the slave server executing the script after performing the target operation; and the target server updates the first data table based on the second parameter information and the warning information. Thus, when the script execution state is the second state, the first parameter information, the second parameter information, and the warning information are obtained.

[0096] Optionally, in step 105, if the execution result is correct, before the target server sends the first operation instruction to the main server, the method may further include the following steps:

[0097] The target server outputs the first parameter information, the second parameter information and the alarm information based on the updated first data table and the second data table;

[0098] The target server obtains a confirmation instruction confirming that the execution result is correct, where the confirmation instruction is obtained based on the first parameter information, the second parameter information and the alarm information;

[0099] If the first parameter information and the second parameter information are inconsistent, the target server performs visually enhanced display on the first parameter information and the second parameter information.

[0100] In some embodiments, the above-mentioned confirmation instruction may be an instruction input by an operator, and the instruction input by the above-mentioned operator may be a judgment instruction on whether the above-mentioned execution result is correct based on the above-mentioned first parameter information, the above-mentioned second parameter information and the above-mentioned alarm information output from the server; or, the above-mentioned confirmation instruction may also be a judgment instruction obtained by the above-mentioned target server after judging whether the above-mentioned execution result is correct based on the above-mentioned first parameter information, the above-mentioned second parameter information and the above-mentioned alarm information.

[0101] Among them, the above-mentioned visual enhancement display can be the inconsistent parts of the above-mentioned first parameter information and the above-mentioned second parameter information, that is, the changes in the target operation object before and after the execution of the above-mentioned target operation are visually enhanced. For example: different colors of text are used to output the inconsistent parts of the above-mentioned first parameter information and the above-mentioned second parameter information. Furthermore, different colors of text can also be used for the operation types of the above-mentioned target operation. Taking the operation types of the above-mentioned target operation including "add", "delete" and "modify" as an example, when the target operation is of the add type, the inconsistent parts of the above-mentioned first parameter information and the above-mentioned second parameter information are displayed in blue; when the target operation is of the delete type, the inconsistent parts of the above-mentioned first parameter information and the above-mentioned second parameter information are displayed in red; when the target operation is of the modify type, the inconsistent parts of the above-mentioned first parameter information and the above-mentioned second parameter information are displayed in yellow. The above-mentioned visual enhancement display can also include the use of bold text display, adding a markup box display, enlarging text, etc., and this application does not impose any restrictions on this.

[0102] In this implementation, the target server outputs the first parameter information, the second parameter information and the alarm information based on the updated first data table and the second data table; the target server obtains a confirmation instruction to confirm that the execution result is correct, and the confirmation instruction is obtained based on the first parameter information, the second parameter information and the alarm information; in this way, the target server can store the first parameter information, the second parameter information and the alarm information through the first data table and the second data table, and can output the first parameter information, the second parameter information and the alarm information, so as to realize the judgment of whether the execution result of the target operation is correct.

[0103] In addition, when the target server outputs the first parameter information, the second parameter information and the alarm information based on the updated first data table and the second data table, if the first parameter information and the second parameter information are inconsistent, the slave server performs visually enhanced display of the first parameter information and the second parameter information. When the operator is required to judge whether the execution result of the target operation is correct based on the output first parameter information, the second parameter information and the alarm information, a visual enhancement effect can be achieved.

[0104] For ease of understanding, the following examples are provided:

[0105] The embodiment of the present application also provides a configuration and change error protection system based on dynamic operation prediction, including a master and a slave, and the master and the slave are set up based on a master-slave hot standby mechanism, such as Figure 2 As shown, the configuration and change error protection system can specifically include six functional modules: a unified operation module, an execution status determination module, a script execution module, an operation prediction module, an operation response module, and a resource library.

[0106] Among them, based on the master-slave hot standby mechanism of the operation object, the operator selects the required operation type from the three operation types of "add, delete, and modify" in the unified operation module according to the configuration and change requirements, and then enters the operation instruction and calls the syntax verification function of the operating system to perform syntax verification on the operation instruction; after the operation syntax verification is completed, the execution status determination module and the script execution module are used to determine the current execution status among the three execution states of initial operation status, system migration status, and normal operation status, and perform configuration and change operations on the "slave machine", as well as execute the script file, and update the corresponding data of the resource library according to the script execution results; then, in the operation prediction module, according to the updated resource library, the resource map and prediction alarm information are obtained, and the operation results are visually predicted; finally, in the operation response module, the operator confirms the configuration and change operations based on the obtained operation prediction results; after confirmation, the configuration and change operations are directly performed on the "master machine", and master-slave hot machine backup is performed. After the above series of execution processes, effective protection against configuration and change operation errors can be achieved, the correctness of configuration and change operations can be ensured, and security issues such as service errors and business interruptions caused by configuration and change errors can be prevented.

[0107] The embodiment of the present application also provides a configuration and change error protection method based on dynamic operation prediction, such as Figure 3 As shown, the following steps may be specifically included:

[0108] Step 1: Based on the configuration and change requirements, the operator selects the required operation type from the three types of "add, delete, and modify" in the unified operation module, and then enters the operation instruction;

[0109] Step 2: Call the syntax check function of the operating system to perform syntax check on the input operation instruction: if the operation syntax is "wrong", return to step 1 and repeat the operation; if the operation syntax is "correct", execute the next step.

[0110] Step 3: In the execution status determination module, the execution status of the script is determined by the number of times the script has been executed and the change of the host control right. Specifically, if the host control right of the operating environment has not changed and the number of script executions is 0, it means that the system has not been migrated and the script has not been executed. At this time, the execution status is the initial operation state (Status=INIT); if the host control right of the operating environment has not changed and the number of script executions is greater than 0, it means that the system has not been migrated and the script has been executed. At this time, the execution status is the normal operation state (Status=NORMAL); if the host control right of the operating environment has changed, it means that the system has been migrated. At this time, the execution status is the system migration state (Status=TRANSFER).

[0111] Step 4: Based on the output result of the execution status determination module, in the script execution module, execute the script on the "slave machine", obtain the resource map element value and pre-judgment alarm information defined according to the requirements, and update the resource library according to the script execution result. Specifically, it can include three situations: (1) If the execution status is the initial operation status (Status = INIT), execute the script on the "slave machine", and update the table table (current status table) in the resource library according to the element value of the resource map and pre-judgment alarm information obtained after the script execution. Do not update the pre-table table (previous status table). At this time, the pre-table table is an empty table. Then, perform the "configuration and change operation" on the "slave machine", and then execute the script on the "slave machine". After the script is executed, the resource map field contents of the operation object table are first copied to the pre-table table, and then the table table in the resource library is updated according to the element values ​​of the resource map and the predicted alarm information obtained after the script is executed; (2) If the execution status is the system migration status (Status = TRANSFER), the script is executed on the "slave", and according to the element values ​​of the resource map and the predicted alarm information obtained after the script is executed, the table table in the resource library is updated and the pre-table table is cleared. Then, the "configuration and change operation" is performed on the "slave", and then the script is executed on the "slave". After the script is executed, the resource map field contents of the operation object table are first copied to the pre-table table, and then the table table in the resource library is updated according to the element values ​​of the resource map and the predicted alarm information obtained after the script is executed; (3) If the execution status is the normal operation status (Status = NORMAL), the "configuration and change operation" is performed on the "slave", and then the script is executed on the "slave". After the script is executed, the resource map field contents of the table being operated on are copied to the pre-table table. Then, based on the resource map element values ​​and predicted alarm information obtained after the script is executed, the table in the resource library is updated. Then, proceed to the next step.

[0112] Specifically, different script execution states will result in different updates to the resource library. The script execution state is indicated by "Status," the initial operation state is indicated by "INIT," the system migration state is indicated by "TRANSFER," and the normal operation state is indicated by "NORMAL."

[0113] The resource library consists of data tables of operation objects. Each operation object has two corresponding data tables, namely the pre-table table (previous state table) and the table table (current state table) of the operation object. The pre-table table fields are composed of resource map fields, and the table table fields are composed of resource map fields and prejudgment alarm information fields. The specific contents of the resource map fields and prejudgment alarm information fields can be flexibly defined according to different usage scenarios. For example, the commonly used operation objects "process files, iptables (IP packet filtering system), ACL files (Access Control List), key files, system logs, databases" can be stored in the resource library as follows (assuming that system x exists):

Please proceed with caution!"; (2) If it is a "Delete" operation, the value of the Predicted Alarm Information field will be "You have deleted the login account [user name], which will reduce the number of users accessing system x. Please proceed with caution!"; (3) If it is a "Modify" operation, the value of the Predicted Alarm Information field will be "You have modified the login account [user name], which will change the access credential information of system x.

Then, proceed to the next step.

[0139] Step 6: Based on the output of the operation prediction module, the configuration and change operation is confirmed in the operation response module.
