mysql主从同步从库同步报错

1.在从库上设置master_info信息时出错

mysql> change master to master_host='192.168.157.143',master_port=3306,master_user='backup',master_password='redhat',master_log_file='mysql-bin.000002',master_log_pos=597;

ERROR 1201 (HY000): Could not initialize master info structure; more error messages can be found in the MySQL error log

2.解决方法

mysql> slave stop;     <--停掉slave

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

mysql> reset slave;    <--重设置一个slave;

Query OK, 0 rows affected (0.00 sec)

mysql> change master to master_host='192.168.157.143',master_port=3306,master_user='backup',master_password='redhat',master_log_file='mysql-bin.000002',master_log_pos=597;    <--再次设置同步信息

Query OK, 0 rows affected (0.05 sec)

mysql> slave start;                        <--启动slave

Query OK, 0 rows affected (0.00 sec)

mysql> show slave status \G;        <--同步正常

  Slave_IO_Running: Yes
  Slave_SQL_Running: Yes
