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

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;
  • 然后重新设置主从复制。

具体过程如下:

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;  
Query OK, 0 rows affected (0.00 sec)  
  
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;  
Query OK, 0 rows affected (0.11 sec)
