[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Figure 1 is a flowchart of a method for replacing an operating system provided by an embodiment of the present invention, which is applied to a management server, such as Figure 1 As shown, the method may include:

[0035] Step 101: When establishing a communication connection with a client node on which a first operating system is installed, obtain current first configuration information of the first operating system from the client node.

[0036] In the embodiment of the present invention, referring to Figure 2 , which shows an implementation scenario diagram provided by an embodiment of the present invention, including: a management server and multiple client nodes. The embodiment of the present invention aims to interact with the client node that needs to replace the operating system through the management server, thereby automatically realizing the replacement of the first operating system to the second operating system in the client node and minimizing manual intervention in the process.

[0037] In this step, the management server first needs to establish a communication connection with the client node installed with the first operating system. After the communication connection is established, data information interaction can be achieved between the management server and the client node, so that the management server can obtain the current first configuration information of the first operating system from the client node.

[0038] Specifically, after obtaining the communication address of the client node, the management server can establish a communication connection with the client node. Furthermore, the client node can extract the current first configuration information of its own first operating system (old operating system) and send it to the management server. The current first configuration information of the first operating system is used to reflect the configuration of the software package, network configuration, system configuration and other information of the business application currently involved and installed by the client node. This information can be used by the management server to understand the business deployment and configuration of the current operating system of the client node, so that the management server can subsequently generate system replacement tasks that meet the needs of the client node itself based on this information.

[0039] Step 102: Generate a system replacement task corresponding to each of the client nodes according to the first configuration information, wherein the system replacement task includes second configuration information corresponding to each of the client nodes.

[0040] Optionally, the first configuration information and the second configuration information both include: one or more of network configuration information, software package configuration information, and system configuration information.

[0041] In an embodiment of the present invention, when a client node needs to be replaced and a new operating system installed, the new operating system must ensure that the previous business deployment of the client node remains unchanged, and also needs to ensure that the previous configuration of the client node (system configuration, software package configuration, network configuration, etc.) remains unchanged. Since the first configuration information reflects the business conditions and configuration conditions of the client node that have been deployed before, the management server can generate a system replacement task corresponding to each client node based on the first configuration information, and the system replacement task can include the second configuration information corresponding to the client node.

[0042] Specifically, the system replacement task is an automatically executable software process, and the system replacement task can be sent by the management server to the client node for automatic operation. The second configuration information is the information existing in the system replacement task, and the second configuration information inherits the business applications and related configurations deployed by the first configuration information, and can restore the original business deployment and related configurations in the new operating system of the client node when the client node executes the system replacement task.

[0043] Step 103: Send the system replacement task to the client node, so that the client node generates a second operating system according to the second configuration information to replace the first operating system.

[0044] After the management server sends the system replacement task to the client node, the client node can automatically execute the system replacement task and generate a second operating system to replace the first operating system according to the second configuration information in the system replacement task. The client node can restore the original business deployment and related configurations in the client node while installing the new second operating system.

[0045] Optionally, the method may further include:

[0046] Step 104: In response to the modification operation on the software package configuration information of the second configuration information, modify the software package configuration information of the second configuration information.

[0047] It should be noted that the second configuration information may also be configuration information obtained after further secondary modification based on the first configuration information. The relevant modification may be determined by actual needs, and the embodiment of the present invention does not limit this.

[0048] For example, the first configuration information defines that the client node has business application a, business application b, and business application c installed. According to actual needs, it is expected to add a business node d to the client node. The second configuration information can further define business application d based on the definition that the client node has business application a, business application b, and business application c installed.

[0049] Optionally, the method may further include:

[0050] Step 105: Acquire the communication address of the client node, and establish a communication connection with the client node according to the communication address.

[0051] In one implementation of the embodiment of the present invention, a staff member may obtain the communication address of the client node and input the communication address into the operating software platform of the management server, so that the management server may establish a communication connection with the client node through the communication address.

[0052] Optionally, the method further includes:

[0053] Step 106: Obtain the system replacement status information sent by the client node.

[0054] Step 107: Generate and store a system replacement log according to the system replacement status information of the client node.

[0055] In an embodiment of the present invention, for steps 106-107, after completing the operating system replacement, the client node can generate system replacement status information and send it to the management server. The system replacement status information reflects the execution result of the client node's operating system replacement operation, including replacement success, replacement failure and other information. Based on the system replacement status information, the management server can generate and store a system replacement log. The system replacement log generated by the management server can be used to reflect the management server's system replacement record for batch client nodes. Later, the system replacement of the client nodes can be managed based on the system replacement log.

[0056] Reference Figure 3, which shows an interactive step flow chart of an operating system replacement method provided by an embodiment of the present invention, including: S1, the management server collects the first configuration information to be replaced in the client node; S2, the client node returns the first configuration information; S3, the management server generates a system replacement task corresponding to the client node and sends it to the corresponding client node; S4, the client node automatically completes the operating system replacement according to the system replacement task, and sends the system status information after the replacement to the management server; S5, the management server restarts the client node after detecting that the replacement is successful, and restores the original operating system of the client node if the replacement fails; finally, S6, the management server can also generate a system replacement log for the administrator to view.

[0057] In summary, in the operating system replacement method provided by the embodiment of the present invention, the management server generates a system replacement task corresponding to the client node according to the current first configuration information of the first operating system of the client node, and sends the system replacement task containing the second configuration information to the client node, so that the client node can automatically execute the system replacement task and generate the second operating system to replace the first operating system. The client node can automatically install the new second operating system and restore the original business deployment and related configurations in the client node according to the second configuration information, thereby realizing unified management of the replacement of operating systems of batch client nodes. The whole process is fast and simple, which greatly reduces the dependence on manual replacement and reduces the workload and complexity of operating system replacement.

[0058] Figure 4 is a flowchart of a method for replacing an operating system provided by an embodiment of the present invention, which is applied to a client node, wherein the client node is installed with a first operating system, such as Figure 4 As shown, the method may include:

[0059] Step 201: When a communication connection is established with a management server, current first configuration information of a first operating system is provided to the management server, so that the management server generates a system replacement task corresponding to the client node according to the first configuration information.

[0060] In an embodiment of the present invention, the client node can provide its own communication address to the management server. After obtaining the communication address of the client node, the management server can establish a communication connection with the client node. After establishing the communication connection, the client node can provide the management server with the current first configuration information of the first operating system. The current first configuration information of the first operating system is used to reflect the business applications, network configurations, system configurations and other information currently involved and installed by the client node. This information can be used by the management server to understand the business deployment and configuration of the current operating system of the client node, so that the management server can subsequently generate system replacement tasks that meet the needs of the client node itself based on this information.

[0061] Step 202: When the system replacement task sent by the management server is obtained, the system replacement task is parsed to obtain second configuration information corresponding to the client node.

[0062] In the embodiment of the present invention, the system replacement task is an automatically executable software process, and the system replacement task can be sent by the management server to the client node for automatic operation. The second configuration information is information existing in the system replacement task, and the second configuration information inherits the business application and related configuration deployed by the first configuration information, and can restore the original business deployment and related configuration in the new operating system of the client node when the client node executes the system replacement task.

[0063] Step 203: Replace the first configuration information with the second configuration information, so that the first operating system of the client node is replaced by the second operating system.

[0064] After the management server sends the system replacement task to the client node, the client node can automatically execute the system replacement task and generate a second operating system to replace the first operating system according to the second configuration information in the system replacement task. The client node can restore the original business deployment and related configurations in the client node while installing the new second operating system.

[0065] Optionally, the first configuration information and the second configuration information both include: one or more of network configuration information, software package configuration information, and system configuration information.

[0066] Optionally, in the process of the client node providing the first configuration information, the method further includes:

[0067] Step 204: Obtain the network configuration information of the first configuration information through the path: / etc / sysconfig / network-scirpts / .

[0068] In the embodiment of the present invention, the network card configuration files can be extracted from the path of the client node: / etc / sysconfig / network-scirpts, and these files can be used as the network configuration information of the first configuration information.

[0069] Step 205: Obtain the software package configuration information of the first configuration information by running the rpm-qa command.

[0070] In an embodiment of the present invention, the client node can obtain a list of all packages installed by the current first operating system through RPM (a powerful command-line driven software package management tool used to install, uninstall, verify, query and update software packages on the Linux system) by running the rpm-qa command. The information in the list can be extracted and used as the software package configuration information of the first configuration information, so that the software package configuration information reflects the configuration of the business application implemented for the first operating system in the current client node.

[0071] Step 206: Obtain system configuration information of the first configuration information by acquiring a system configuration file and a configuration file of system installation software.

[0072] The system configuration information includes all system configuration files in the / etc / directory, as well as all configuration files for system installed software in the / usr / local and / opt / directories.

[0073] Optionally, step 203 may specifically include:

[0074] Sub-step 2031: Modify the yum source of the first operating system through the second configuration information, thereby replacing the first configuration information.

[0075] Sub-step 2032: When it is determined that the availability check of the modified yum source passes, the replacement operation of the first operating system to the second operating system is completed by running the modified yum source.

[0076] In the embodiment of the present invention, for sub-steps 2031-2032, the yum (Yellow Dog Updater, Modifier) ​​source is a free, open source command line software package management tool that can run on a Linux operating system based on RPM package management. The yum source can automatically download and install RPM packages from a specified server based on RPM package management, and can automatically handle dependency relationships, installing all dependent software packages at one time without the need to download and install them tediously again and again.

[0077] Therefore, based on the second configuration information in the system replacement task sent by the management server, the client node can update and replace the software repository of the yum source, that is, replace the software application deployment and related configuration defined by the first configuration information with the software application deployment and related configuration defined by the second configuration information.

[0078] Furthermore, after the replacement, the availability of the modified yum source can be determined. When it is determined that the availability check of the modified yum source passes, the replacement operation of software deployment and related configurations from the first operating system to the second operating system is completed by running the modified yum source.

[0079] The availability check of the yum source includes: adding the repo file to the / etc / yun.d.repo / directory, executing yum clean all, and then executing yum makecache to return information without error, indicating that the yum source is available.

[0080] Optionally, after step 203, the following steps may also be included:

[0081] Step 207: Execute a system restart operation, and after the restart is completed, obtain the system replacement status information.

[0082] Step 208: Send the status information of the system after replacement to the management server.

[0083] In an embodiment of the present invention, for steps 207-208, after completing the operating system replacement, the client node can generate system replacement status information and send it to the management server. The system replacement status information reflects the execution result of the client node's operating system replacement operation, including replacement success, replacement failure and other information. Based on the system replacement status information, the management server can generate and store a system replacement log. The system replacement log generated by the management server can be used to reflect the management server's system replacement record for batch client nodes. Later, the system replacement of the client nodes can be managed based on the system replacement log.

[0084] Optionally, the method may further include:

[0085] Step 209: Back up the relevant files of the first operating system.

[0086] After step 203, the method may further include:

[0087] Step 210, in response to the system recovery instruction sent by the management server, the operating system currently running on the client node is restored to the first operating system based on the backed-up related files of the first operating system; the system recovery instruction is an instruction sent by the management server when the status information check after the system replacement fails.

[0088] In an embodiment of the present invention, with respect to steps 209-210, the client node may also back up the relevant files of the original first operating system before replacing the operating system, and after replacing the first operating system with the second operating system, in response to the recovery system instruction sent by the management server, restore the operating system currently running on the client node to the first operating system based on the relevant files of the backed-up first operating system.

[0089] Among them, the system recovery instruction is an instruction sent by the management server when the system status information check after replacement fails. Therefore, when the management server believes that the operating system replacement of the client node is unsuccessful, the management server can also restore the original first operating system of the client node to ensure the normal operation of the client node and avoid abnormal operation of the client node due to unsuccessful operating system replacement.

[0090] In summary, refer to Figure 5 , which shows a replacement action flow chart of a client node provided by an embodiment of the present invention, including: the client node parses the replacement configuration file to obtain the second configuration information; then the client node backs up the source system and installs the in-situ replacement tool, and then the client node replaces the Yum repository with the repo of the second operating system; the client node performs the local replacement operation, and then the management server only needs to check the operating system after replacement, complete the operating system replacement if the check passes, and restore the original operating system backed up by the client node if the check fails.

[0091] In summary, in the operating system replacement method provided by the embodiment of the present invention, the management server generates a system replacement task corresponding to the client node according to the current first configuration information of the first operating system of the client node, and sends the system replacement task containing the second configuration information to the client node, so that the client node can automatically execute the system replacement task and generate the second operating system to replace the first operating system. The client node can automatically install the new second operating system and restore the original business deployment and related configurations in the client node according to the second configuration information, thereby realizing unified management of the replacement of operating systems of batch client nodes. The whole process is fast and simple, which greatly reduces the dependence on manual replacement and reduces the workload and complexity of operating system replacement.

[0093] The acquisition module 301 is used to acquire the current first configuration information of the first operating system from the client node when establishing a communication connection with the client node on which the first operating system is installed;
