Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a server high availability implementation method provided by an embodiment of the present invention, which is applicable to a situation where a primary server and a standby server contend for resources, and the method may be performed by a server high availability implementation apparatus, where the method may be implemented by hardware and/or software, and may be generally integrated in a device. Wherein the device may be a standby server.
As shown in fig. 1, the method specifically includes the following steps:
s110, under the condition that the abnormality of the main server is detected, the target resource table of the main server is inquired and updated.
In the embodiment, the exception of the primary server may be understood as that no response information fed back by the primary server is received after the standby server sends the heartbeat information to the primary server. In the embodiment, after the standby server sends the heartbeat information to the main server, there are two cases that the response information fed back by the main server is not received: firstly, when the standby server detects heartbeat information, the main server breaks down briefly and recovers later; secondly, when the standby server takes over the service, the main server does not release the storage resource.
In the embodiment, the target resource table refers to the resource table of the standby server itself. In the target resource table, resource items are stored so that the standby server performs allocation planning on resources. In the embodiment, when the main server is detected to be abnormal, the standby server inquires the target resource table of the standby server and updates the target resource table of the standby server to take over the service and provide the service to the outside.
And S120, adjusting the current working state of the standby server to be an occupied state.
In an embodiment, the current working states of the primary server and the standby server can be divided into two cases, namely an occupied state and an available state. In the embodiment, when the current working state is the occupied state, the storage resources in the target resource tables of the main server and the standby server are indicated, and the service is taken over; and in the case that the current working state is the available state, indicating that the resources are not stored in the target resource tables of the main server and the standby server and the service is not taken over.
In the embodiment, when the abnormality of the main server is detected, the standby server queries and updates the target resource table of the standby server and takes over the related services managed by the main server. Meanwhile, the standby server adjusts the current working state of the standby server from an available state to an occupied state so as to indicate that the standby server is processing the related service.
And S130, under the condition of receiving the resource request instruction sent by the main server, feeding back the current working state of the standby server to the main server so that the main server adjusts the current working state of the standby server to be an available state.
In an embodiment, the resource request instruction may be understood as an instruction to obtain related resource information in a target resource table of the standby server. In an embodiment, in the case that the primary server is abnormal and recovers, the primary server sends a resource request instruction to the standby server to synchronize the related resource information in the target resource table of the standby server. In the actual operation process, since the primary server is just abnormal and just recovered, the primary server may be unstable, and at this time, the standby server only feeds back the current working state of the standby server to the primary server, instead of synchronizing the resource information in the target resource table to the primary server. After the main server receives the current working state of the standby server, the main server adjusts the current working state of the main server to be an available state, and enters a to-be-repaired mode to wait for related technical personnel to repair the main server so as to determine the reason of the abnormality of the main server.
According to the technical scheme in the embodiment, through adjustment of the current working states of the main server and the standby server, after the main server is abnormal and recovers, whether the main server can take over the service or not is determined according to the current working state of the standby server, so that the condition of resource contention of the main server and the standby server is avoided, high availability of the server is simply and easily realized at low cost, online uninterrupted or rarely interrupted, and the purpose of continuous service of the server is achieved.
In one embodiment, the method for detecting the abnormality of the main server includes: sending heartbeat information to a main server; and in a first preset time, response information corresponding to the heartbeat information fed back by the main server is not received, and the main server is determined to be abnormal.
In an embodiment, a local area private network is used to communicate heartbeat information between the primary server and the backup server to determine whether the primary server is abnormal. Specifically, the standby server sends heartbeat information to the main server at regular time, and if the main server feeds back response information, the main server is indicated to be in a normal working state, namely, no abnormality occurs; on the contrary, if the standby server does not receive the response information corresponding to the heartbeat information fed back by the main server within the first preset time, it is determined that the main server is abnormal. The first preset time is determined by negotiating according to a gateway protocol between the primary server and the backup server, which is not limited herein.
Fig. 2 is a schematic diagram of interaction between a primary server and a standby server according to an embodiment of the present invention. As shown in fig. 2, the primary server 210 and the standby server 220 negotiate with each other through a gateway protocol. Between the primary server 210 and the standby server 220, the related resource information in the target resource table is synchronized through the private lan, and the external service is provided through the lan.
In one embodiment, the number of primary servers and backup servers is not limited. For example, two main servers and two standby servers can be used for providing services to the outside, and adjustment can be performed according to actual conditions.
In an embodiment, in a case of receiving a resource request instruction sent by a primary server, after feeding back a current working state of a standby server to the primary server, the method further includes: sending heartbeat information to the main server at intervals of second preset time; under the condition of receiving response information fed back by the main server, synchronizing the resource information in the target resource table to the main server; and adjusting the current working state of the standby server to be an available state.
In the embodiment, when the standby server receives the resource request instruction sent by the main server, after the standby server feeds back the current working state of the standby server to the main server, the main server adjusts the current working state of the main server to be an available state, and enters a to-be-repaired mode. After the standby server feeds back the current working state of the standby server to the main server, heartbeat information is sent to the main server at intervals of second preset time to detect whether the main server is in a state of completing maintenance or not, if the standby server receives response information fed back by the main server within the first preset time, the standby server indicates that the main server is completed maintenance and can work normally, and in order to guarantee the processing rate of service, relevant resource information in a target resource table of the standby server can be synchronized to the main server to enable the main server to take over the service, and the current working state of the standby server is adjusted to be an available state from an occupied state.
In one embodiment, the current working states of the main server and the standby server are represented in a binary signaling manner.
In an embodiment, under the condition that the binary signaling is a first numerical value, the current working states of the main server and the standby server are occupied states; and under the condition that the binary signaling is a second value, the current working states of the main server and the standby server are available states. In the embodiment, the current operating states of the main server and the standby server are represented by means of binary signaling, which can be understood that the current operating states of the main server and the standby server can only be two cases. In this embodiment, when the binary signaling is a first value, the current working states of the main server and the standby server are occupied states, for example, the first value may be 1; correspondingly, when the second value is 0, that is, the binary signaling is 0, the current working states of the main server and the standby server are available.
In an embodiment, when the abnormality of the primary server does not occur, the target resource tables of the primary server and the standby server are consistent, the current working state of the primary server is an occupied state, and the current working state of the standby server is an available state. In an embodiment, binary signaling for the primary and standby servers is initialized, i.e., 0 indicates an available state and 1 indicates an occupied state. Under the condition that the main server is in a normal state, the target resource table of the main server is consistent with the target resource table of the standby server, the binary signaling corresponding to the main server is 1, and the binary signaling corresponding to the standby server is 0.
And under the condition that the standby server finds that the main server is abnormal through the heartbeat information, inquiring a target resource table of the standby server and updating the target resource table so as to take over the related service of the main server. Under the condition that the main server is recovered, the main server needs to inquire a target resource table of the standby server, and if the standby server is processing related services, the standby server does not take over the services, so that the condition that the main server and the standby server compete for resources is avoided.
In an embodiment, when a resource request instruction sent by a main server is received, the current working state of a standby server is fed back to the main server, so that the main server releases storage resources.
In the embodiment, when the standby server receives a resource request instruction sent by the main server, the standby server feeds back the current working state of the standby server to the main server, so that the main server knows that the standby server is processing related services, and if the main server does not release the storage resource when an exception occurs, the main server knows that the standby server is processing related services, and the main server needs to release the storage resource, so as to avoid resource contention between the main server and the standby server.
