mysql互为主从,但是在SLAVE执行CHANGE MASTER时,出现这个错误:
mysql> slave stop;
mysql> change master to master_host='172.17.2.10',master_user='sync',master_password='123456',master_log_file='updatelog.000004',master_log_pos=106;
ERROR 1201 (HY000): Could not initialize master info structure; more error messages can be found in the MySQL error log
在另外一台上执行也是一样提示这个错误。 网上查了一些资料,发现大概有两种方法解决这个问题,,1.是清理mysql的相关日志;2.是reset slave ;但是清理日志的方法有点复杂,使用第2种方法比较方便。
mysql> slave stop;
mysql> reset slave;
mysql> change master to master_host='172.17.2.10',master_user='sync',master_password='123456',master_log_file='updatelog.000004',master_log_pos=106;
mysql> slave start;
另外一台也按照这种方法执行,轻松搞定。配置完成查看mysql主从同步状态正常!
mysql > show slave status \G;
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
