Problems solved by technology

At this time, if the backup server takes over the business and the service runs on two nodes at the same time after the host recovers from suspended animation, double hanging of disk arrays will occur, resulting in loss of user data.
And if the backup server does not take over the business, the cluster cannot provide external services normally

Embodiment 1

[0024] Such as figure 2 In the topology diagram of the high-availability cluster system shown, the system has L nodes, and all nodes are connected to a centralized remote power manager. Each node has three network cards eth0, eth1, and eth2. As two different heartbeat network cards, eth0 and eth1 are responsible for transmitting heartbeat signals and communicating between nodes. eth2 is connected to the border router as the working link NIC, and provides external services through floating IP. After the cluster software is started, a master node is elected. The master node is responsible for state synchronization among cluster nodes, node scheduling, service deployment, etc. Every time a service is deployed, the node scheduling algorithm will select a suitable node for each service to deploy, and the node running the service is the active node.

Abstract

The invention provides a highly available cluster system feign death solution based on both remote detection and power management, which belongs to the technical field of computer cluster. The state of a service operation node is detected through a service detection script, then the node is re-started by adopting the remote power management technology, and the service can be migrated to a backup node after re-start of the node, so that high availability and data security of the system are ensured, and the situation that the service operates at two nodes simultaneously after recovery of feign death of a host computer is avoided. Therefore, the operating stability of the whole system is guaranteed. The solution can be widely applied to the technical field of computer cluster.

Description

technical field [0001] The invention belongs to the technical field of computer clusters, in particular to a method for solving high-availability clusters (High-availability clusters) system suspended animation. Background technique [0002] With the continuous expansion of computer application fields and the rapid development of communication network technology, key areas such as telecommunications, finance, and e-government have higher and higher requirements for continuous server operation. Business stoppages caused by server downtime and other failures will bring In order to cope with this situation, the current common method is to use a high-availability cluster system. Even if a server fails, user business and data can be quickly switched to the backup server, thus ensuring the external service of the entire system. Normal, providing a strong guarantee for the key business applications of enterprises 24 hours x 365 days. [0003] However, one problem that is difficult...
