MySQL master-slave configuration, error

Fatal error:the slave I/O thread stops because master and slave have equal MySQL server IDs;

Cause Analysis:

Similar to Server_uuid, SERVIER_ID has to be guaranteed to be different.

Workaround:

Locate the server_id in the MY.CNF configuration file, modify the server_id from the library to be different from the other db in the replication structure, and restart the DB

Note: If the image is not newly run or copied

Find/-name AUTO.CNF

Restart MySQL after deleting auto.cnf
