Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a first flowchart of a cluster partnership establishment method according to an embodiment of the present application.
The method for establishing the cluster partnership provided by the embodiment of the application is applied to a target cluster and can comprise the following steps:
step S101: and screening out a first main node and a first redundant node in the target cluster.
In practical application, a target cluster may screen a first main node and a first redundant node in its own cluster, where the first main node refers to a main node screened in the target cluster, and the first redundant node refers to a redundant node screened in the target cluster. The manner of screening the first master node and the first redundant node by the target cluster may be determined according to a specific application scenario, and the present application is not limited herein.
Step S102: receiving first communication address information issued by a partner cluster, wherein the first communication address information comprises a partner cluster identifier of the partner cluster and communication address information of a target node set in the partner cluster; the target node set comprises a second main node and a second redundant node.
In practical application, after the first master node and the first redundant node are screened out by the target cluster, the target cluster can be in a state of receiving first communication address information issued by a partner cluster, and the partner cluster in the application refers to a cluster establishing a partner relationship with the target cluster. In a specific application scenario, the partner cluster may first screen out the second master node and the second redundant node, and the second master node and the second redundant node are used as a target node set connected to the target cluster, where the second master node refers to a master node in the partner cluster, and the second redundant node refers to a redundant node in the partner cluster, and after the partner cluster screens out the second master node and the second redundant node, the partner cluster identifier of the partner cluster and the communication addresses of the second master node and the second redundant node may be integrated into the first communication address information, and the first communication address information is transmitted to the target cluster.
Step S103: and judging whether the partner cluster identifier is consistent with the identifier stored by the partner cluster identifier, if so, executing the step S104.
Step S104: and establishing a first communication link between the first main node and the target node set and simultaneously establishing a second communication link between the first redundant node and the target node set through the first communication address information.
In practical application, after receiving the first communication address information, the target cluster may first determine whether the partner cluster identifier is consistent with the identifier stored in the target cluster, and if so, establish a first communication link between the first main node and the target node set and simultaneously establish a second communication link between the first redundant node and the target node set through communication addresses of a second main node and a second redundant node in the first communication address information; it should be noted that, in this process, the establishment manners of the communication links between the first host node, the first redundant node, and the target node set may be flexible and variable, for example, the first host node may only establish the first communication connection with the second redundant node, and the second redundant node only establishes the second communication connection with the second redundant node, or the first host node may also establish the first communication connection with the second host node and the second redundant node, and the first redundant node may also establish the communication connection with the second host node and the second redundant node, and the like. It is to be understood that the partner cluster identification ensures that the partner cluster to which the target cluster is connected is a preset cluster. In addition, when a communication link between the nodes is established, the communication link may be established through login information, for example, the login information of the first host node logging in the second host node is sent to the second host node, so that the second host node determines whether to establish the communication link according to the login information; correspondingly, the second host node may send login information for logging in the first host node to the first host node, so that the first host node determines whether to establish a communication link or not according to the received login information.
Step S105: and communicating the first communication link and judging whether the first communication link is in a communicated state, if not, executing the step S106.
Step S106: one of the second communication links is communicated.
In practical application, after the target block link node establishes the first communication link and the second communication link, the first communication link may be communicated, so that the target cluster and the partner cluster may perform information transmission through the first communication link, and may determine whether the first communication link is in a communicated state, if not, one of the second communication links is communicated, so that the second communication link replaces the first communication link to perform information transmission between the target cluster and the partner cluster. It should be noted that the present application does not limit the number of nodes in the first master node, the first redundant node, the second master node, and the second redundant node, for example, the first master node may be one master node, or may be three master nodes.
In a specific application scenario, the target cluster may determine whether the first communication link is in a connected state in real time, or may determine whether the first communication link is in a connected state according to a preset time interval, or the like; furthermore, the number of second communication links is influenced by the number of redundant nodes, since one redundant node in the target cluster can establish a communication connection with only one redundant node in the partner cluster.
The method for establishing the cluster partnership is applied to a target cluster, and a first main node and a first redundant node are screened out from the target cluster; receiving first communication address information issued by a partner cluster, wherein the first communication address information comprises a partner cluster identifier of the partner cluster and communication address information of a target node set in the partner cluster; the target node set comprises a second main node and a second redundant node; judging whether the partner cluster identifier is consistent with the identifier stored by the partner cluster identifier, if so, establishing a first communication link between a first main node and a target node set through first communication address information, and establishing a second communication link between a first redundant node and the target node set; and communicating the first communication link, judging whether the first communication link is in a communicated state, and if not, communicating one communication link in the second communication link. According to the method for establishing the cluster partnership, the target cluster is connected with the partner cluster, so that the partner cluster can back up information in the target cluster, the data stability of the target cluster is protected, when the target cluster is connected with the partner cluster, connection between the first main node and the target node set is established, and connection between the first redundant node and the target node set is established, so that when the connection between the first main node and the target node set is disconnected, communication connection between the first redundant node and the target node set can be started quickly, the influence of the disconnection of the communication connection between the first main node and the target node set on the target cluster is reduced, and the storage performance of the target cluster is improved.
The method for establishing the cluster partnership provided by the embodiment of the application is applied to a target cluster, and is used for improving the stability of communication connection established between the target cluster and a partner cluster, the target cluster can establish communication connection with the partner cluster through twice connection, so that after receiving first communication address information issued by the partner cluster, the target cluster can also send first response information of the received first communication address information to the partner cluster and enter a waiting connection state before judging whether a partner cluster identifier is consistent with an identifier stored by the target cluster; sending second communication address information generated by the self to a partner cluster, wherein the second communication address information comprises a target cluster identifier and communication address information of a first main node and a first redundant node; and judging whether second response information sent by the partner cluster is received or not, if so, executing a step of judging whether the partner cluster identifier is consistent with the identifier stored by the partner cluster identifier.
