1、由于binlog日志带多删除了几个后发现MySQL主从不同步

mysql> show slave status\G;

Slave_IO_Running: No
Slave_SQL_Running: Yes

查看报错日志为

[ERROR] Slave I/O: Got fatal error 1236 from master when reading data from binary log: 'Could not find first log file name in binary log index file',

解决方式

从服务器配置：

主服务器查看

mysql> show master status;

+------------------+----------+--------------+------------------+

| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |

+------------------+----------+--------------+------------------+

| mysql-bin.000005 | 106 | | |

+------------------+----------+--------------+------------------+

1 row in set (0.00 sec)

从服务器设置

mysql> change master to master_host='192.168.0.10',master_user='replication',master_password='replication',master_log_file='mysql-bin.000003',master_log_pos=106;

Query OK, 0 rows affected (0.03 sec)



mysql>stop slave;

mysql>start slave;



主服务器配置

从服务器上查看

mysql> show master status;

+------------------+----------+--------------+------------------+

| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |

+------------------+----------+--------------+------------------+

| mysql-bin.000005 | 106 | | |

+------------------+----------+--------------+------------------+

1 row in set (0.00 sec)

主服务器配置

mysql> change master to master_host='192.168.0.11',master_user='replication',master_password='replication',master_log_file='mysql-bin.000005',master_log_pos=106;

Query OK, 0 rows affected (0.03 sec)

mysql>stop slave;

mysql>start slave;

在查看slave状态ok解决。
