This article introduces the example analysis of mysql master-slave replication cluster library IO process, the content is very detailed, interested friends can refer to, hope to be helpful to you.

Configure mysql master-slave replication. Check the slave status after starting the slave process. The IO process reports an error:

Last_IO_Error: Fatal error: The slave The slave O thread stops because master and slave have equal MySQL server ids; these ids must be different for replication to work (or the-- replicate-same-server-id option must be used on slave but this does not always make sense; please check the manual before using it).

Reason: the server-id parameter of the cluster library is the same as that of the main library, which needs to be changed to other values, and the cluster library needs to be restarted (in this case, it is not restarted after modification)

On the mysql master-slave replication cluster library IO process case analysis is shared here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
