Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Referring to fig. 1, fig. 1 is a flow chart of an embodiment of a distributed server cluster node management method provided by the present invention, as shown in fig. 1, the method includes steps 101 to 103, 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 the information of each functional service module of the server node corresponding to the service management server side to generate a functional service module list, wherein the information of each functional service module of the server node is acquired by the corresponding service management terminal and written into the service management server side.
In this embodiment, for 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 servers and at least two service management servers are deployed in the entire 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 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 obtains 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 side is used for collecting the functional service module information on a plurality of server nodes, information synchronization is realized among different service management server sides, and a single service management server side can collect the functional service module information corresponding to all server nodes in the whole server cluster.
In this embodiment, based on the designs of the service management terminal and the service management server, the function service modules of each server node are easily invoked. 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 its own server node, that is, tells the service management server about information of the first service function module, for example, an interface, an IP port configuration, port information, etc. of the first service function module, because of cluster deployment between service management servers, information synchronization between 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 the server cluster; and repeating the steps by all the service function modules in other server nodes so that the service function module information on all the server nodes in the server cluster is concentrated on any service management server.
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 functional service module information to be called, and the functional service module information 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 of the functional service module. As an example in this embodiment, when the second service function module of the second server node wants to call the first service function module on the first server node, a query instruction is sent to the service management terminal on the second server node, where the query instruction includes the 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 of 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 returns the service management server on the second server node to tell the second service function module of the second server node about the first service function module on the first server node, so that a 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 call function modules between different server nodes are implemented.
In this embodiment, the node management server is mainly configured to collect system information of all server nodes in the server cluster, and may issue an instruction to the node management terminal, for example, modify IP configuration; simultaneously, web call is provided, and the web can write network configuration information to the server; the node management terminal is used for reporting own server node information, such as information of own node IP address, port, firewall configuration, NAT configuration and the like, to the node management server in real time. 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 between node management service ends, information synchronization between deployed node management service ends is caused, that is, node information of any server node exists on any node management service end in a server cluster.
In this embodiment, the node management terminal of any one server node in the server cluster sends registration information to any one service management server through the service management terminal of the server node of the node management terminal, so that the IP and port information of the server node are sent to any one service management server.
In this embodiment, because of the communication connection between the service management server and the plurality of node management terminals, the service management server obtains the corresponding server node information of the plurality of node management terminals, and generates the node information list, and when the ip information of the node management terminal of any one server node in the server cluster changes, the service management server can quickly obtain the ip information of the corresponding node management terminal after the change, and update the node information list.
In this embodiment, the service management server side simultaneously obtains information of each functional service module of the server nodes corresponding to the service management server sides, and generates a functional service information list, so that when an administrator accesses the system through the web side, the module information can be displayed to the administrator through the web side. Meanwhile, the displayed module information can be partially filtered according to the requirements, such as the packet loss rate of the current system, and if the web end has no related requirements, the packet loss rate information of the system can be filtered.
Step 102: and acquiring and updating the node information list and the function service module list according to node configuration information of a database, and writing the updated node information list and the updated function service module list into the database to update the database.
In this embodiment, the node management center of the node management server acquires server node configuration information in the database from the database, updates the node information list and the function service module list acquired in step 101 according to the server node configuration information in the database, and writes the updated node information list and the updated function service module list into the database at the same time, 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 function service module list to the service management terminal at regular time through the node management terminal so as to keep alive with the node management terminal and the service management server.
In this embodiment, since the update of the database needs to rely on the writing of information by the node management server, there is information synchronization between the node management server and the database, and at this time, the node management server obtains server node information of the entire server cluster and service function module information of the entire server cluster; the node management server uploads the updated node information list and the updated function 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 mutually 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 mutually kept alive, 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 is changed, the node management server may timely obtain the changed server node information from other server components, and modify the corresponding server node information stored in the node management server.
In this embodiment, for modification of the node information list, when each service component operates normally and keep alive is normal, 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 and feeds back a modification state, and meanwhile, node modification information is sent 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 terminal operation, for example, when modifying an IP port configuration, a node management server receives a node modification instruction of the administrator, and issues a node modification instruction to a service management terminal of a corresponding server node, when the service management terminal executes the node modification instruction to modify the IP port configuration, the service management terminal sends information of successful modification to the service management server, and simultaneously sends the server node information after successful modification to the service management server through the service management terminal on the server node, so that the server node information is synchronously modified on the service management server, at this time, the node management server notifies the database to write the updated server node information, and simultaneously notifies the web terminal that the operation is completed, so that the web terminal prompts the administrator that the operation is successful.
In this embodiment, when an abnormality occurs to a certain server node in the server cluster, the node management terminal of the server node may be abnormal, so that the node management terminal does not upload the updated node information list to the service management terminal at regular time, so that the node management terminal communicates with the node management server, and the server node corresponding to the node management terminal is marked as abnormal, for example, a yellow alarm; if the service management server cannot acquire node information in the updated 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 the node management server and the service management server both consider that the information is overtime, the server node corresponding to the node management terminal is marked as offline, such as a red alarm. In this embodiment, the node management server and the service management server determine twice, and after the confirmation information is overtime, the server node is defined as offline, so that accuracy can be further improved.

In this embodiment, the service management terminal provides an interface to each functional service module of the server node, and obtains and writes information of all functional service modules of the server node to the service management server through the service management terminal.

In this embodiment, the node management terminal of any one server node in the server cluster sends registration information to any one service management server through the service management terminal of the server node of the node management terminal, so that the IP and port information of the server node are sent to any one service management server.
In this embodiment, because of the communication connection between the service management server and the plurality of node management terminals, the service management server obtains the corresponding server node information of the plurality of node management terminals, and generates the node information list, and when the ip information of the node management terminal of any one server node in the server cluster changes, the service management server can quickly obtain the ip information of the corresponding node management terminal after the change, and update the node information list.
