Abstract

The invention discloses a method for switching a master server and a slave server and a monitoring server. The method comprises the steps of checking whether a registered resource node exists in a Zookeeper device or not, wherein the resource node is a label of the resource; when the registered resource node exists in the Zookeeper device, checking whether the number of server nodes in child nodes of the resource node is larger than or equal to a preset value; when the number of the server nodes in the child nodes of the resource node is larger than or equal to the preset value and a main server in the child nodes of the current resource node is not available, switching one slave server in the child nodes of the resource node into the main server. According to the method, the risks of data loss caused by the existence of two main servers at the same time cannot happen, and problems existing in the prior art are solved.

Description

technical field [0001] The embodiment of the present invention relates to server coordination technology, and in particular to a master-slave server switching method and a monitoring server. Background technique [0002] When the server provides services, the master-slave device is usually used to ensure high availability. For example, MySQL uses Heartbeat software to achieve high availability of the master-slave architecture. At least two servers are used in the high availability scheme realized by Linux Heartbeat, and the at least two servers include a central server, and the central server maintains connections with other servers through Heartbeat. The core of Heartbeat includes two parts, the heartbeat monitoring part and the resource takeover part. Heartbeat monitoring can be performed through network links and serial ports, and supports redundant links. They send messages to each other to tell each other their current status. If the message sent by the other party is ...
