Mysql主从库不同步1236错误：could not find first log file name in binar

Mysql主从库不同步1236错误:could not find first log file name in binary log index file错误是主从的一个日志问题,我们只要简单的配置一下即可解决.　

近日遇到了Mysql主从库不同步问题,主要是因为电脑断了一下电,折腾啊.

从库日志中的错误: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'

解决办法:

1.首先停止从库同步:slave stop;

2.主库中清空日志:flush logs;

3.查看主库状态,主要查看日志文件和位置:show master status;

4.回到从库中,执行命令,使日志文件和位置对应主库:

CHANGE MASTER TO MASTER_LOG_FILE='log-bin.000005',MASTER_LOG_POS=107;

5.最后,启动从库:slave start; 成功解决！
