Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the method for controlling server switching according to the preferred embodiment of the present invention includes the following steps:
and step S10, starting a main server and a standby server, and controlling the main server and the standby server to start a key service detection program.
Specifically, the number of the standby servers (backup servers) in the present invention may be one or more, that is, there is one main server and one standby server in the backup scheme, and preempting means preempting the main server. When the server is switched, the destination server of the switching is obtained by the preemption of a plurality of servers, and if the alternative server to be switched is regarded as a denomination, the plurality of alternative servers preempt the denomination.
The key service detection program is used for calling the key service at regular time to monitor the running state of the key service.
And step S20, when the key service is detected, judging whether the key service is effective, and when the key service is effective, the key service detection program reports service data to a service management center.
Specifically, the key service can quickly find whether a background service is available or not, so as to achieve the purpose of timely switching, where the key service refers to which service is core content under the condition that a server provides functions, for example, a WeChat provides multiple functions, then login may be the key service, and after the service makes a mistake, the server still needs to be switched although other services are normally performed.
The method uses key service detection, and the written key service detection program detects service availability to trigger switching server operation. Compared with the existing switching mode for detecting the process running state, the method solves the problems that the process state is normal and the server cannot be switched normally when the service state is abnormal (such as the process state is normal when the server is stuck and the service is unavailable) aiming at the service content. And because the switching condition is whether the service state is normal or not, the method is more suitable for the actual requirement of improving the availability of the system.
Wherein the service data comprises: server hardware information, whether a key service is called successfully, the time for calling a service, and a service name. The server hardware information includes: CPU information, memory information, and operating terminal information.
Further, when the key service is judged to be invalid, the main server and the standby server are restarted, and the main server and the standby server are controlled to restart the key service detection program.
And step S30, the key service detection program applies for preemption service, and the preemption service applies for preemption of the main server.
Specifically, a key service detection program applies for preemption service, a main server and a standby server exist in a backup scheme, and preemption refers to preemption of the main server.
Step S40, determining whether the preemption service is successful, and if the preemption is successful, broadcasting a service information change message for notifying a service change dependency associated with the primary server.
Specifically, if the broadcast service information change message is successfully preempted, the service preemption success represents that the change of the main server is about to occur, and therefore a message needs to be sent to allow other services related to the service to change the dependency relationship. The message content comprises: server name, server IP information.
Further, if the preemption service is unsuccessful, controlling the main server and the standby server to start the key service detection program again after a preset time delay.
The preemptive switching of the invention does not need to decide the switching server in advance, the method sets a service management center, when the background service is started, the service content of the center is registered, a plurality of servers with consistent content automatically form a group, when the switching is needed, the server initiates the preemptive operation to complete the selection of the switching target, the mode does not need to configure the switching target server in advance, the number of the servers can be dynamically increased, compared with the traditional pre-configuration scheme, the preemptive switching is not needed, and the flexibility is higher.
Further, as shown in fig. 2, the whole process of server switching control in the present invention is as follows:
starting the main server and the standby server after starting;
controlling the main server and the standby server to start a key service detection program;
judging whether the key service is effective or not after the key service is detected;
when the key service is effective, the key service detection program reports service data to a service management center;
when the key service is invalid, restarting the main server and the standby server, and controlling the main server and the standby server to restart a key service detection program;
the key service detection program applies for a preemption service, and the preemption service applies for preemption of the main server;
judging whether the preemption service is successful or not;
and if the preemption service is unsuccessful, controlling the main server and the standby server to start a key service detection program again after a preset time delay (namely timing delay).
And if the preemption is successful, broadcasting a service information change message for notifying the service change dependency relationship associated with the main server.
The invention provides a preemptive server switching method based on a key service state, wherein a key service checking program can trigger the operation of a switching server according to a service available state, the server actively applies for the preemptive server in a preemptive mode, and the sequence of switching the server is determined by the service state. The method is particularly suitable for using hot and cold backup (which is a server disaster tolerance scheme generally accepted in the industry, and is an operation method for switching to a standby server when a single server is unavailable, and the standby server switching is possible only by using a backup scheme, so that the method is particularly suitable) so as to improve the system availability.
