[0072] In order for those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings.

[0073] It should be noted that the terms "first", "second", and the like in the specification and claims of the present disclosure and the above-described drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented in an order other than that illustrated or described herein. The implementation described in the following exemplary embodiments does not represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0074] In order to facilitate the understanding of the present disclosure, among the technical terms related to the present disclosure:

[0075] For example, an object providing a service can be represented as a process. A service can correspond to multiple instances, which are usually running in different servers, and each instance can provide the service independently.

[0076] The master instance refers to the instance that actually provides the service.

[0077] The slave instance refers to the instance other than the master instance.

[0078] The analysis instance refers to the instance that monitors whether the master instance is abnormal.

[0079] It should be noted that the role of each instance is not always the same, but will change over time, and an instance can also have the roles of slave and analysis instances.

[0080] Figure 1 is a schematic diagram of an architecture of a service system according to an exemplary embodiment, which includes at least two servers 11 and at least one storage device 12 (such as various types of databases), and each server 11 is connected to the storage device 12 through a communication network. Each server 11 starts an instance that can provide a service, and the identification and creation time of the instance can be stored in the storage device 11, and the active time of the instance can be stored in the storage device 11 periodically. Therefore, the storage device 11 stores instance information of each instance, which can include the identification, creation time and last active time of the instance.

[0081] The following will be described in conjunction with Figure 1 The service providing method provided by the embodiments of the present disclosure will be introduced.

[0082] Figure 2 is a flowchart of a service providing method according to an exemplary embodiment, as Figure 1 shown, the service providing method is used in each server 11, and the flowchart of the method includes the following steps.

[0083] In step S201, instance information of each instance is obtained from a storage device.

[0084] In step S202, whether the master instance is abnormal is determined according to the instance information of each instance.

[0085] Taking an example in which the instance information of each instance includes a creation time and a last active time of the instance.

[0086] In implementation, whether the locally started instance is the master instance can be determined based on the creation time of each instance and the creation time characteristics of the master instance. For example, if the creation time characteristics of the master instance are that the creation time is the earliest, the instance with the earliest creation time among the instances can be determined as the master instance; if the creation time characteristics of the master instance are that the creation time is the latest, the instance with the latest creation time among the instances can be determined as the master instance. In addition, each instance has an identifier, and the identifier of the locally started instance is compared with the identifier of the master instance. If they are the same, it means that the locally started instance is the master instance, and if they are not the same, it means that the locally started instance is not the master instance.

[0087] Then, when it is determined that the locally started instance is not the master instance, whether the master instance is abnormal is analyzed based on the last active time of the master instance.

[0088] In some embodiments, a time difference between a current time and the last active time of the master instance can be determined, and if the time difference is greater than a preset time length, it is determined that the master instance is abnormal. In this way, whether the master instance is abnormal can be quickly determined, which is beneficial to quickly switching the master instance when the master instance is abnormal and shortening the interruption time of the service.

[0089] In some embodiments, a time difference between a current time and the last active time of the master instance can be determined, and after it is determined that the time difference is greater than a preset time length, the preset time length is waited for, and then the last active time of the master instance is obtained from the storage device again. If the last active time of the master instance obtained this time is the same as the last active time of the master instance obtained last time, it is determined that the master instance is abnormal. In this way, the last active time of the master instance is confirmed twice, which can avoid misrecognition caused by different time synchronization between different servers, thereby improving the accuracy of the judgment of the abnormality of the master instance.

[0090] In some embodiments, the storage device also stores communication address information of each instance. At this time, after determining that the last active time of the current acquired master instance is the same as the last active time of the last acquired master instance, the communication address information of the master instance acquired from the storage device is also acquired, and then a heartbeat request is sent to the master instance based on the communication address information of the master instance. If the master instance does not respond to the heartbeat request, it is determined that the master instance is abnormal. In this way, both the last active time of the master instance is confirmed again and communication with the master instance is performed to determine whether the master instance is abnormal, which can further improve the accuracy of the abnormality judgment of the master instance.

[0091] In step S203, when it is determined that the master instance is abnormal, the master instance is reselected so that the reselected master instance provides the service.

[0092] In specific implementation, the instance information of each instance can be reacquired from the storage device, and the master instance is reselected from the instances other than the abnormal master instance based on the creation time of each instance and the creation time characteristics of the master instance, and the service is provided by the reselected master instance.

[0093] In addition, when the service system includes at least three servers, before analyzing whether the master instance is abnormal based on the last active time of the master instance, it can also be determined that the creation time of the locally started instance meets the creation time characteristics of the analysis instance. When the creation time characteristics of the master instance is the earliest creation time, the creation time characteristics of the analysis instance can be the second earliest creation time; when the creation time characteristics of the master instance is the latest creation time, the creation time characteristics of the analysis instance can be the second latest creation time.

[0094] That is, when there are at least three servers, it is not necessary for each slave instance other than the master instance to analyze whether the master instance is abnormal, but only the analysis instance in the slave instances needs to analyze whether the master instance is abnormal. In this way, the thundering herd effect that all slave instances will perceive the abnormality of the master instance and perform abnormal analysis when the master instance is abnormal can be avoided.

[0095] In the embodiments of the present disclosure, the instances other than the master instance can monitor the activity of the master instance, and the master instance is reselected to provide the service when the master instance is abnormal, so that the instances in the multiple servers can continuously provide the service without relying on external devices.

[0096] Figure 3 is a flowchart of another service providing method according to an example embodiment, as shown in Figure 1 The service providing method is used in any server 11, and the flowchart of the method includes the following steps.

[0097] In step S301, instance information of each instance is obtained from the storage device, and the instance information of each instance includes a creation time and a last active time.

[0098] In step S302, whether the locally started instance is the master instance is determined based on the creation time of each instance and the creation time feature of the master instance, if yes, step S303 is entered, and if no, step S304 is entered.

[0099] In step S303, the master instance provides a service.

[0100] In step S304, if it is determined that the creation time of the locally started instance meets the analysis of the creation time feature of the instance, whether the master instance is abnormal is analyzed based on the last active time of the master instance.

[0101] In step S305, when it is determined that the master instance is abnormal, the instance information of the master instance is deleted from the storage device.

[0102] In order to avoid selecting an abnormal master instance as a new master instance, the instance information of the master instance is deleted from the storage device when it is determined that the master instance is abnormal, considering that the instance information of each instance obtained from the storage device is also needed when the master instance is reselected.

[0103] In step S306, the master instance is reselected, so that the reselected master instance provides a service.

[0104] In specific implementation, the instance information of each instance can be reobtained from the storage device, the master instance is reselected from each instance based on the creation time of each instance and the creation time feature of the master instance, and the service is provided by the newly selected master instance.

[0105] In addition, in any of the above embodiments, when it is determined that the instance exit condition is met, the locally running instance can be exited, and the instance information of the instance can be deleted from the storage device, so as to avoid that the instance information of the exited instance remains in the storage device and affects the selection of the subsequent master instance.

[0106] The scheme of the embodiment of the present disclosure is described below taking the storage device mysql as an example.

[0107] Figure 4 An activity flowchart of an instance provided by the embodiment of the present application includes the following steps:

[0108] In step S401, the server starts an instance.

[0109] In step S402, a universally unique identifier (uuid) corresponding to the instance is generated as its identifier.

[0110] In step S403, the uuid and the creation time creat_time of the instance are saved into the mysql.

[0111] In step S404, a preset time length is waited.

[0112] The preset time length is, for example, 1 second.

[0113] In step S405, if it is determined that the instance is still alive, the update time update_time corresponding to the uuid in the mysql is updated as the current time.

[0114] The update_time is used for recording the last active time of the instance.

[0115] In step S406, it is judged whether the instance exit condition is met, if not, it returns to S404, and if yes, it enters S407.

[0116] In step S407, the instance information of the instance is deleted from the mysql.

[0117] The instance information includes the uuid, creat_time and update_time of the instance.

[0118] In step S408, the instance is exited.

[0119] Figure 5 An activity flowchart of another instance provided by the embodiment of the present application includes the following steps:

[0120] In step S501, the uuid, creat_time and update_time of all instances in the mysql are acquired.

[0121] In step S502, it is judged whether the uuid of the self is the uuid of the earliest main instance of the creat_time, if yes, it enters S507, and if not, it enters S503.

[0122] In step S503, it is judged whether the uuid of the self is the uuid of the second earliest analysis instance of the creat_time, if yes, it enters S504, and if not, it enters S505.

[0123] In step S504, it is judged whether the earliest main instance of the creat_time is abnormal, if yes, it enters S505, and if not, it enters S506.

[0124] Figure 6 A flowchart for judging whether the main instance is abnormal provided by the instance of the present application includes the following steps:

[0125] In step S601a, it is judged whether the time difference between the current time and the acquired update_time of the master instance is greater than t seconds, if yes, it goes to S608a, if not, it goes to S602a.

[0126] In step S602a, it waits for t seconds.

[0127] In step S603a, the update_time of the master instance is re-acquired.

[0128] In step S604a, it is judged whether the update_time of the master instance acquired this time is the same as the update_time of the master instance acquired last time, if yes, it goes to S605a, if not, it goes to S608a.

[0129] In step S605a, based on the communication address information of the master instance acquired from the mysql, a heartbeat request is sent to the master instance.

[0130] The communication address information is, for example, a network address and a port.

[0131] In step S606a, it is judged whether the heartbeat request is normally responded, if yes, it goes to S608a, if not, it goes to S607a.

[0132] In step S607a, it is determined that the master instance is abnormal.

[0133] In step S608a, it is determined that the master instance is normal.

[0134] In step S505, it waits for 1 second.

[0135] In step S506, the instance information of the master instance is deleted from the mysql.

[0136] In step S507, it is determined that itself is the master instance, and based on the master instance, a service is provided.

[0137] In step S508, it is judged whether the instance exit condition is met, if yes, it goes to S509, if not, it goes to S501.

[0138] In step S509, the instance running locally is exited.

[0139] The disclosed example has the following advantages:

[0140] 1. The decentralized master instance switching is realized by the instance in each server sharing the instance information in the storage device;

[0141] 2. The abnormality misjudgment of the master instance caused by the time inconsistency of different servers or the Network Time Protocol (NTP) jump can be avoided by the delayed confirmation, and the accuracy of the abnormality judgment of the master instance can be further improved by the point-to-point heartbeat confirmation.

[0142] 3. The stampede effect that all the remaining instances perceive and perform the abnormality judgment when the master instance is abnormal can be avoided by limiting that only the second early created instance performs the abnormality judgment.

[0143] Based on the same technical concept, the disclosure also provides a service providing apparatus. The principle of the service providing apparatus for solving the problem is similar to the above-mentioned service providing method, and therefore the implementation of the service providing apparatus can be referred to the implementation of the service providing method, and the repeated parts will not be described herein.

[0151] Before analyzing whether the master instance is abnormal based on the last active time of the master instance, it is determined that the creation time of the locally started instance meets the creation time feature of the analysis instance.

[0152] In some embodiments, the determining unit 702 is specifically configured to perform:

[0153] determining a time difference between a current time and the last active time of the master instance;

[0154] if the time difference is greater than a preset time length, determining that the master instance is abnormal.

[0168] As to the apparatus in the above-described embodiments, in which various units perform the specific functions as requested, the detailed description has been given in the embodiments about the method, and thus will not be repeated here.

Claims

1. A method for providing business services, characterized in that, The method is applied to a business system, which includes a storage device and at least three servers, each server running an instance. The storage device stores instance information for each instance, including its creation time and last active time. Each of the servers obtains instance information for each instance from the storage device; Based on the creation time of each instance and the creation time characteristics of the primary instance, it is determined whether the locally started instance is the primary instance; wherein, the creation time characteristics of the primary instance are the earliest or latest creation time; If it is determined that the locally started instance is not the primary instance, then it is determined whether the creation time of the locally started instance matches the creation time characteristics of the analysis instance; wherein, if the creation time characteristic of the primary instance is the earliest creation time, and the creation time characteristic of the analysis instance is the second earliest creation time, then it matches the creation time characteristics of the analysis instance; or, if the creation time characteristic of the primary instance is the latest creation time, and the creation time characteristic of the analysis instance is the second latest creation time, then it matches the creation time characteristics of the analysis instance. If the creation time of the locally started instance matches the creation time characteristics of the analyzed instance, then analyze whether the main instance has an anomaly based on the last active time of the main instance. When it is determined that the primary instance is abnormal, a new primary instance is selected so that the newly selected primary instance can provide business services. When the instance exit conditions are met, the locally running instance is exited, and the instance information of the instance is deleted from the storage device to avoid the instance information of the exited instance remaining in the storage device and affecting the selection of the subsequent primary instance.
