搭建mysql 主从复制The slave I/O thread stops because master and slave have equal MySQL server UUIDs

mysql 搭建主从复制 报错：
Last_IO_Error: Fatal error: The slave I/O thread stops because master and slave have equal MySQL server UUIDs; these UUIDs must be different for replication to work.

具体原因：是因为两台服务器是克隆出来，uuid是一样的

启动mysql,然后查询

mysql> show variables like 'datadir';
+---------------+------------------------+
| Variable_name | Value                  |
+---------------+------------------------+
| datadir       | /usr/local/mysql/data/ |
+---------------+------------------------+

mysql> select uuid();
+--------------------------------------+
| uuid()                               |
+--------------------------------------+
| 0eff2534-f39d-11ec-8a20-000c290868b7 |
+--------------------------------------+
1 row in set (0.00 sec)

[root@ygt01 mysql]# cd /usr/local/mysql/data/
[root@ygt01 data]# vi auto.cnf
用 0eff2534-f39d-11ec-8a20-000c290868b7 代替auto.cnf的uuid

重启mysql

systemctl restart mysql
