ERROR 1201 (HY000):Could not initialize master info structure的问题

今天在做MySQL主从复制时遇到个ERROR 1201 (HY000): Could not initialize master info structure .

出现这个问题的原因是之前曾做过主从复制！

解决方案是：运行命令 stop slave;

成功执行后继续运行 reset slave;

然后进行运行GRANT命令重新设置主从复制。

具体过程如下：

Command代码

mysql> change master to master_host='127.0.0.1', master_user='user', master_pass

word='user', master_log_file='mysql-bin-000202', master_log_pos=553;

ERROR 1201 (HY000): Could not initialize master info structure; more error messa

ges can be found in the MySQL error log

mysql> stop slave;

Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> reset slave;
