mysql server id一样导致报错

(root@localhost) 16:03:38 [(none)]> show slave status \G;
                Last_IO_Errno: 1593
                Last_IO_Error: Fatal error: The slave I/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)

处理：

由于是GTID模式，reset master

清空 auto.cnf文件

auto.cnf

获取本机uuid

(root@localhost) 16:10:06 [(none)]>  SELECT UUID(), UUID(), LENGTH(UUID()), CHAR_LENGTH(UUID()) \G
*************************** 1. row ***************************
