Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a method and a device for processing master-slave switching of a server.
Background
The OP _ CLUSTER is independently developed CLUSTER management software, HAs High Availability (HA) and Disaster Recovery (DR) capabilities, and is used for connecting multiple servers to cooperatively provide services by adopting multi-level redundancy in order to avoid hardware and software failures of the servers. In the event of a single server, or software failure, a switchover or restart function is provided. And when single point failures of the network, the data and the hardware are ensured, the quick recovery is realized, and the service is continuously provided.
The OP _ CLUSTER performs CLUSTER deployment on a CLUSTER of NEA (Network element adapter) software by adopting a mode of 'multiple main devices and one standby device' through a deployment scheme of an N +1 CLUSTER. The plurality of main servers run independently without mutual interference; one standby server takes over the work of the failed main server at any time. The heartbeat lines between the main server nodes and the standby server nodes are not connected in a direct connection mode any more, but are uniformly accessed into a private network formed by switching equipment by the main server nodes and the standby server nodes; the active/standby server service network adapters are also uniformly connected to the "public network" switching device, as shown in fig. 1.
In the prior art, the OP _ CLUSTER adopts an asynchronous heartbeat mode, the heartbeat is sent sequentially to a main machine and a standby machine in the sending process, for example, the heartbeat is sent to the main machine firstly and then to the standby machine, and if the main machine does not receive the heartbeat in the 3-time heartbeat process, the main machine is considered to be in fault, and the main machine is automatically switched to the standby machine. However, in the actual use process, the 3 heartbeats may be only due to packet loss or delayed non-timely response, the host is switched to the standby machine under the normal condition, and the host and the standby machine both have running processes, so that the problem of double masters occurs, which causes the abnormal access of the base station to the network management system, thereby causing large-area reporting of network element broken link alarm and causing large-batch base station offline.

Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Fig. 2 is a flowchart illustrating a main/standby switching processing method of a server according to this embodiment, where the method includes:
s201, if the host/standby machine judges that the learning process is abnormal, judging the heartbeat receiving condition.
The host is a server of a currently running process, the standby machine is a server of which the process is in an un-started state, a connection schematic diagram of the host and the standby machine is shown in fig. 3, and the host (a host access server) and the standby machine (a standby access server) are respectively and fully connected with each switch.
For example, the NEA process is run in the host, and the NEA process in the standby is not started; when the main and standby are switched, the NEA process of the current host is suspended, the NEA process of the current standby is started, and at the moment, the previous standby is converted into the host, so that the host and the standby are relative concepts.
Specifically, when the host and the standby machine determine that the processes are abnormal, the heartbeat receiving conditions of the current host and the standby machine can be determined. And the host and the standby synchronously receive the heartbeat sent by the cluster management software.
S202, if the heartbeat sent by the cluster management software is not received within a preset time period, acquiring the running state of the corresponding standby machine/host machine.
The preset time period is preset time according to the heartbeat sending period and the heartbeat sending frequency. The heartbeat transmission cycle refers to the time interval between two heartbeats, and the heartbeat transmission frequency refers to the frequency of continuously transmitting heartbeats. For example, the heartbeat sending cycle is 2s, the heartbeat sending frequency is 5, and the preset time period is 15s, the cluster management software sends 1 heartbeat every 2s within 15s, and continuously sends 5 heartbeats, the host/standby machine only needs to receive one heartbeat within 15s, if the host/standby machine does not receive the heartbeat within 15s, the host needs to obtain the running state of the standby machine, and the standby machine needs to obtain the running state of the host.
The operating state includes normal or abnormal.
And S203, if the corresponding standby machine/host machine is judged to be normally operated according to the operation state, executing the main-standby switching of the server, and switching from the host machine/standby machine to the corresponding standby machine/host machine.
Specifically, referring to fig. 4, when the host determines that the standby device is operating normally, the host performs active-standby switching of the server, the host stops operating the process, and the standby device starts the process to operate; or, when the standby machine judges that the host machine operates normally, the standby machine of the server is switched, the standby machine stops operating the process, the host machine starts the process to operate, and the OP _ CLUSTER software synchronously detects the heartbeat of the standby machine in a synchronous heartbeat mode, so that the double-master problem caused by an asynchronous heartbeat mechanism is avoided.
In the embodiment, by adopting a synchronous heartbeat mode, after the heartbeat of the main machine and the standby machine is synchronously detected by the cluster management software, the main machine/the standby machine performs main-standby switching after judgment, so that the double-main problem caused by an asynchronous heartbeat mechanism is solved, and the operation efficiency of the base station is improved.
Further, on the basis of the above embodiment of the method, the method further comprises:
and S204, if the heartbeat sent by the cluster management software is received within a preset time period, the main-standby switching of the server is not executed.
And S205, if the corresponding standby machine/host machine is judged to be abnormal according to the running state, the main-standby switching of the server is not executed.
Specifically, referring to fig. 4, when the host/standby machine receives the heartbeat sent by the cluster management software, it is proved that the connection of the host/standby machine is normal, and the host/standby switching of the server does not need to be executed; when the host/standby machine does not receive the heartbeat sent by the cluster management software and the state of the corresponding standby machine/host machine is abnormal, the host/standby machine is proved to be incapable of normally operating the process, so that the host/standby switching of the server cannot be executed to ensure the normal operation of the process.
S206, if the success rate of the main-standby switching is judged and obtained to be smaller than the preset value according to the history data of the main-standby switching, reducing the heartbeat sending period and/or increasing the heartbeat sending frequency.
The history data of the main-standby switching is whether the main-standby switching is successful or not after each time, namely whether the process can normally operate or not after the main-standby switching, if the process normally operates, the switching is successful, and if the process does not normally operate, the switching fails.
When the success rate of the active-standby switching is too small, the heartbeat sending period needs to be reduced and/or the heartbeat sending frequency needs to be increased, namely, the time interval between two heartbeats is shortened, and the frequency of continuously sending heartbeats needs to be increased. For example, the original heartbeat is sent every 5 seconds, and the failure is judged when the heartbeat is not received for 3 times, the heartbeat period is shortened to 2 seconds, the judgment frequency is changed to 5 times, and the condition of heartbeat loss caused by packet loss is prevented, so that the occurrence of misjudgment is effectively prevented, unnecessary main-standby switching is reduced, and the main-standby switching efficiency is improved.
Fig. 5 is a schematic structural diagram of a primary/standby switching processing device of a server according to this embodiment, where the device includes: an exception determining module 501, a state obtaining module 502, and a main/standby switching module 503, wherein:
the anomaly determination module 501 is configured to determine a heartbeat receiving condition if it is determined that the learning process is abnormal;
the state obtaining module 502 is configured to obtain an operating state of the corresponding standby machine/host machine if a heartbeat sent by the cluster management software is not received within a preset time period;
the main/standby switching module 503 is configured to execute main/standby switching of the server if it is determined according to the operating state that the corresponding standby machine/host operates normally, and switch from the host/standby machine to the corresponding standby machine/host;
and the host and the standby synchronously receive the heartbeat sent by the cluster management software.
Specifically, if the anomaly determination module 501 determines that the process is abnormal, it determines the heartbeat receiving condition; if the state obtaining module 502 does not receive the heartbeat sent by the cluster management software within a preset time period, obtaining the running state of the corresponding standby machine/host machine; if the main/standby switching module 503 determines that the corresponding standby/host operates normally according to the operating state, the main/standby switching of the server is executed, and the host/standby is switched to the corresponding standby/host.
In the embodiment, by adopting a synchronous heartbeat mode, after the heartbeat of the main machine and the standby machine is synchronously detected by the cluster management software, the main machine/the standby machine performs main-standby switching after judgment, so that the double-main problem caused by an asynchronous heartbeat mechanism is solved, and the operation efficiency of the base station is improved.
Further, on the basis of the above embodiment of the apparatus, the apparatus further comprises:
