#### 错误异常 ####

Mysql 主从配置时，我通过`show slave state`命令查看从数据库的情况，可以看到 `Last_IO_Error`字段报了错

#### 解决办法: ####

1.  使用`show master status\G`命令查看**主数据库**的log名称和position，例如我的是  
    ![2. 使用][2.]  
    在**从数据库**中使用如下命令进行同步

change master to master_host='192.168.56.80', master_user='repl', master_password='123456', master_log_file='mysql-bin.000004', master_log_pos=340

1.  如果设置完，这两个不一致  
    ![在这里插入图片描述][20200228192932145.png]  
    可以重启一下slave，使用 `slave stop、slave reset、slave start`三个命令。

可以看到

Slave_IO_State: Waiting for master to send event
                      Master_Host: 192.168.56.80
                      Master_User: repl
                      Master_Port: 3306
                    Connect_Retry: 60
                  Master_Log_File: binlog.000004
