The invention discloses an automatic mail server switching method. The method comprises the following steps: deploying a plurality of servers in a mail system to form a server cluster; copying the mail data of each server to a corresponding backup server according to a mirror image synchronization technology; selecting n servers from the server cluster to serve as monitoring servers; monitoring and voting the state of each server in the server cluster in a preset time period by utilizing the monitoring server; judging whether a server corresponding to the voting result is abnormal or not according to the voting result; and if yes, judging that the server corresponding to the voting result is an abnormal server, selecting any normal server from backup servers of the abnormal server, and switching the access request accessing the abnormal server to the normal server. According to the mail server automatic switching method provided by the invention, the accuracy and reliability of mail server automatic switching can be effectively improved, and a user can normally access mail data.
Description
technical field [0001] The invention relates to the technical field of mail services, in particular to a mail server automatic switching method, device and storage medium. Background technique [0002] In order to ensure the high availability and stability of the mail server and reduce the loss caused by the inability to access the mail system due to computer hardware failure or network and other reasons, the existing mail server automatic switching method usually adopts dual-machine hot backup for homogeneous mail system servers + Shared storage solution, that is, two servers are connected to a shared storage device or storage network, and dual-machine hot backup is realized by installing dual-machine software. The two servers will connect to the external network with a virtual IP and send service requests to one of them The server does the work. At the same time, the server detects the working status of the other server through the heartbeat line; when one server fails, t...
