Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
Example 1
Referring to fig. 1, fig. 1 is a schematic flowchart of an embodiment of a distributed server cluster node management method provided by the present invention, and as shown in fig. 1, the method includes steps 101 to 103, which are specifically as follows:
step 101: acquiring corresponding server node information of a plurality of node management terminals, and generating a node information list; and simultaneously acquiring information of each functional service module of a server node corresponding to a plurality of service management service terminals, and generating a functional service module list, wherein the information of each functional service module of the server node is acquired by the corresponding service management service terminal and written into the service management service terminal.
In this embodiment, for the deployment of a server cluster, a node management terminal and a service management terminal are deployed on all cluster server nodes, and at least two node management server sides and at least two service management server sides are deployed in the whole server cluster; the node management server is respectively in communication connection with the plurality of node management terminals, the service management server is respectively in communication connection with the plurality of service node management terminals, and the plurality of node management terminals are correspondingly in communication connection with the plurality of service management terminals.
In this embodiment, the service management terminal provides an interface to each functional service module of the server node, and acquires and writes information of all functional service modules of the server node to the service management server through the service management terminal. The service management server is used for collecting the functional service module information on the plurality of server nodes, information synchronization is realized among different service management servers, and a single service management server can collect the functional service module information corresponding to all the server nodes in the whole server cluster.
In this embodiment, based on the design of the service management terminal and the service management server, mutual calling between the functional service modules of each server node is easily implemented. As an example in this embodiment, for example, a first service function module on a first server node registers service information of the first service function module to any one service management server through a service management terminal on the server node, that is, the first service function module informs the service management server of the information of the first service function module, such as an interface, an IP port configuration, port information, and the like of the first service function module, due to cluster deployment among the service management servers, information synchronization among the deployed service management servers is caused, that is, information of the first service function module of the first server node exists on any one service management server in a server cluster; and repeating the steps by all the service function modules in other server nodes so as to centralize the information of the service function modules on all the server nodes in the server cluster on any service management server side.
In this embodiment, a functional service module in a server node sends a query instruction through a corresponding service management terminal, where the query instruction includes information of the functional service module to be called, and the information of the functional service module includes IP port configuration and interface information; and sending the query instruction to the service management server through the service management terminal, and acquiring the information of the functional service module to be called from the service management server so as to establish communication connection between the functional service modules. As an example in this embodiment, when a second service function module of a second server node wants to call a first service function module on a first server node, a query instruction is sent to a service management terminal on the second server node, where the query instruction includes IP port configuration and interface information of the first service function module on the first server node, so that the service management terminal on the second server node sends the query instruction to the service management server on the second server node and waits for a reply from the service management server on the second server node, and after the service management server on the second server node replies, the service management terminal on the second server node informs the second service function module of the second server node of information about the first service function module on the first server node replied by the service management server on the second server node, therefore, communication connection can be established between the second service function module of the second server node and the first service function module on the first server node, and calling between service function modules of different server nodes is realized.
In this embodiment, the node management server is mainly used to collect system information of all server nodes in the server cluster, and may issue an instruction to the node management terminal, such as modifying IP configuration; meanwhile, the network configuration information is provided for web calling, and the web can write the network configuration information to the server; the node management terminal is used for reporting server node information of the node management terminal to the node management server in real time, such as IP address, port, firewall configuration, NAT configuration and the like of the node management server. In this embodiment, when a plurality of node management terminals report current node information to a single node management service point, due to cluster deployment among node management service terminals, information synchronization among the deployed node management service terminals is caused, that is, node information of any server node exists on any node management service terminal in a server cluster.
In this embodiment, the node management terminal of any server node in the server cluster sends the registration information to any service management server through the service management terminal of its own server node, so that the IP and port information of its own server node are sent to any service management server.
In this embodiment, due to the communication connection between the service management server and the plurality of node management terminals, the service management server obtains the server node information corresponding to the plurality of node management terminals and generates the node information list, and when ip information of a node management terminal of any one server node in the server cluster changes, the service management server can quickly obtain the changed ip information of the corresponding node management terminal and update the node information list.
In this embodiment, the service management server obtains information of each functional service module of the server node corresponding to a plurality of service management servers at the same time, and generates a functional service information list, so that when an administrator accesses the system through the web server, the administrator can display the module information through the web server. Meanwhile, partial filtering can be performed on the displayed module information according to requirements, for example, the packet loss rate of the current system is what, if the web end has no relevant requirements, the packet loss rate information of the system can be filtered.
Step 102: and acquiring and updating the node information list and the functional service module list according to the node configuration information of the database, and writing the updated node information list and the updated functional service module list into the database so as to update the database.
In this embodiment, the node management center of the node management server obtains server node configuration information in the database from the database, updates the node information list and the functional service module list obtained in step 101 according to the server node configuration information in the database, writes the updated node information list and the updated functional service module list into the database, and updates data in the database, so as to make the data in the database persistent. In this embodiment, the database type may be Redis or TiDB.
Step 103: and uploading the updated node information list and the updated functional service module list to the service management terminal through the node management terminal so as to keep the node management terminal and the service management server terminal mutually alive.
In this embodiment, since the update of the database needs to rely on the writing of the node management server to the information, information synchronization exists between the node management server and the database, and at this time, the node management server obtains the server node information of the whole server cluster and the service function module information of the whole server cluster; the node management server uploads the updated node information list and the updated functional service module list to the service management terminal of the corresponding server node at regular time through the node management terminals of different server nodes, so that the node management server is kept alive with the node management terminal and the service management server respectively, and meanwhile, the service management server and the service management terminal are kept alive with each other, but the node management server is not kept alive with the service management server.
In this embodiment, the node management server may obtain server node information of the entire server cluster and service function module information of the entire server cluster, and when the server node information changes, the node management server may timely obtain the changed server node information from other server components, and modify corresponding server node information stored in the node management server.
In this embodiment, for modification of the node information list, when each service component normally operates and keeps alive normally, when a node modification instruction sent by an administrator is detected, the node modification instruction is transmitted to the node management terminal, so that the node management terminal executes the node modification instruction, feeds back a modification state, and sends node modification information to the service management server; and when the fed-back modification state is successful, writing the modified node information into the database, and sending an operation state prompt to the administrator. As an example in this embodiment, when an administrator modifies a server node information through a web-side operation, if the IP port configuration is modified, the node management server side sends the node modification instruction to the service management terminal of the corresponding server node when receiving the node modification instruction of the administrator, when the service management terminal executes the node modification instruction to modify the IP port configuration, the information of successful modification is sent to the service management server, meanwhile, the server node information after being successfully modified is sent to a service management server through a service management terminal on the server node, so that the service management server side can synchronously modify the server node information, at this time, the node management server can inform the database to write the updated server node information, and meanwhile, the web end is informed that the operation is finished so as to prompt an administrator to operate successfully on the web end.
In this embodiment, when a server node in a server cluster is abnormal, a node management terminal of the server node is abnormal, which causes that the node management terminal does not upload an updated node information list to a service management terminal at regular time, so that the node management terminal and a node management server communicate with each other, and the server node corresponding to the node management terminal is marked as abnormal, for example, a yellow alarm; if the service management server side cannot acquire the updated node information in the database from the service management terminal within the preset time, the information is considered to be overtime; meanwhile, if the node management server cannot acquire the updated node information in the database from the service management server, the information is considered to be overtime, and when both the node management server and the service management server consider the information to be overtime, the server node corresponding to the node management terminal is marked as offline, for example, a red alarm. In this embodiment, the node management server and the service management server perform two judgments, and after the confirmation information is overtime, the server node is defined as offline, so that the accuracy can be further improved.
