       今天把两台机器恢复主从关系后,在slave上执行show slave status,结果中显示
 
      2017-04-21T13:46:15.133435Z 8806 [ERROR] Slave I/O for channel '': error connecting to master 'repl@192.168.2.40:3306' - retry-time: 60  retries: 1, Error_code: 1045
首先查看slave的错误日志文件,和上面的错误一样
 
接着用perror查看上一部获得的错误代码:
 
[root@iZ2ze5ifr62amhrpcnpn9yZ mysql]# perror 1045
MySQL error code 1045 (ER_ACCESS_DENIED_ERROR): Access denied for user '%-.48s'@'%-.64s' (using password: %s)
有可能是复制用的账户存在问题,先在MASTER上确认复制用户账户是否存在且是否赋了正确的权限
 
mysql> show grants for repl@192.168.2.41;
+---------------------------------------------------------+
| Grants for repl@192.168.2.41 |
+---------------------------------------------------------+
| GRANT REPLICATION SLAVE ON *.* TO 'repl'@'192.168.2.41' |
+---------------------------------------------------------+
1 row in set (0.00 sec)
发现没有问题,试着从master使用该账户连接至slave,果然没连上
 
[root@iZ2ze5ifr62amhrpcnpn9yZ ~]# mysql -urepl -h 192.168.2.40 -p -P3306
Enter password:
ERROR 1045 (28000): Access denied for user 'repl'@'192.168.2.40' (using password: YES)
之前的密码可能不对,修改一个新的密码
 
 
mysql> update mysql.user set authentication_string=PASSWORD('REPLsafe!@#$41') where User='repl' and host='192.168.2.41';
Query OK, 1 row affected, 1 warning (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 1
mysql> commit;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
试着用新的密码重建复制关系,问题解决。
 
mysql> stop slave;
Query OK, 0 rows affected (0.01 sec)
mysql> change master to
    -> master_host='192.168.2.40',
    -> master_port=3306,

    -> master_password='REPLsafe!@#$41',
    -> master_log_file='bin.000043',
    -> master_log_pos=799072709;
Query OK, 0 rows affected, 2 warnings (0.05 sec)
mysql> start slave;
