Problems solved by technology

[0003] 1. The result of ping is obviously affected by the status of the network. If there is an abnormal connection between the monitor cluster network and the computing node network, but the business network and storage network of the computing node itself are normal, any response made by the monitor cluster according to the ping result may cause The business of the target computing node is affected by the interruption;
[0004] 2. The load of the monitor node will continue to increase with the expansion of the cluster size, which will soon cause network performance bottlenecks and processing bottlenecks for the monitor node;
[0005] 3. The monitor node uses keepalive or pacemaker for multi-active high availability, relies on the vrrp protocol, has high requirements on the network itself, and has relatively poor stability

Embodiment Construction

[0037] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0038] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0039] see figure 1 and figure 2 As shown, a method for high availability of server hosts includes the following steps:

[0040] S1. The daemon process of the computing node agent (the carrier that runs the agent, which is also the actual carrier of the business, and the carrier of the cloud host running the cloud environment) periodically detects its own state. When it detects an abnormal state in its own state, it adds the abnormal state information to the heartbeat message;

[0041] S2. The computing node server runs the agent daemon process and periodically reports heartbeat messages to the domain monitor server;

[0042] S3. Domain monitor (area monitor, which receives the repo...

Abstract

The invention provides a method for high availability of a server host, which comprises the following steps of: reporting step by step in a distributed agent reporting mode; then, the domain monitor performs active detection on nodes which are not reported overtime; the domain monitor reports a result to a control center, and the control center comprehensively judges whether cluster computing nodes are in a normal state or not and whether active migration virtual machine services are triggered or not. The method for high availability of the server host is high in reliability, good in detection accuracy, short in problem response time and more accurate in positioning.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for high availability of a server host. Background technique [0002] At present, the common solution for the high availability of computing node hosts in the cloud computing platform business is mainly the method of pinging each server through monitor detection, that is, a singular monitor node forms a cluster, elects a master node, regularly pings each computing node, and judges based on the returned results Whether the server can communicate normally; but the above method will have the following disadvantages: [0003] 1. The result of ping is obviously affected by the status quo of the network. If there is an abnormal connection between the monitor cluster network and the computing node network, but the business network and storage network of the computing node itself are normal, any response made by the monitor cluster according to the ping result ...
