环境:
OS:Centos 7
DB:mysql 5.7.29
基于GTID复制的主从环境,主库修改了ip后,修改从库同步信息(不需要指定master_log_file和master_log_pos)
1.停掉从库
stop slave;
2.查看从库状态
mysql> show slave status \G;

我这里Auto_Position: 0
3.尝试清理主库的已经同步过的binlog
主库执行:
mysql> purge binary logs to 'binlog.000002';
Query OK, 0 rows affected (0.06 sec)
4.修改ip地址
change master to master_host='192.168.1.104',
master_port=13306,
master_user='repl',
master_password='mysql';
5.启动
start slave;
6.查看
mysql> show slave status \G;
