主从复制进行配置的时候出现如下错误：

Last_IO_Error: Got fatal error 1236 from master when reading data from binary log: 'Could not find first log file name in binary log index file'

错误详情如下：

    1 row in set (0.00 sec)

解决办法：

mysql> stop slave;
    Query OK, 0 rows affected (0.01 sec)
    
    mysql> reset slave;
    Query OK, 0 rows affected (0.00 sec)
    
    mysql> start slave;
    Query OK, 0 rows affected (0.01 sec)

如果还是不可以，解决方案如下：  
1 进入到master数据库执行如下命令：

mysql> reset master;
    
    mysql> show master status;
    +------------------+----------+--------------+------------------+-------------------+
    | File             | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
    +------------------+----------+--------------+------------------+-------------------+
    | mysql-bin.000001 |      154 |              |                  |                   |
    +------------------+----------+--------------+------------------+-------------------+
    1 row in set (0.01 sec)

2 进入到slave数据库，执行如下命令：

mysql> change master to master_host='192.168.1.11',master_user='root',master_password='123456',master_port=3306,master_log_file='mysql-bin.000001', master_log_pos=154;
    
    mysql> stop slave;
    Query OK, 0 rows affected (0.01 sec)
    
    mysql> reset slave;
    Query OK, 0 rows affected (0.00 sec)
    
    mysql> start slave;
    Query OK, 0 rows affected (0.01 sec)

再查看：

mysql> show slave status \G;
