mysql主从库不同步问题解决方法
本来配置可以使用的mysql主从库同步的数据库,突然出现无法同步的情况。那么大家可以参考下面的方法解决下。
遇到这样的错误如:“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'”等或由于清数据导致主从库不同步了,解决办法如下:先进入slave中执行:"slave stop;"来停止从库同步;
再去master中执行:"flush logs;"来清空日志;
然后在master中执行:"show master status;"查看下主库的状态,主要是日志的文件和position;
然后回到slave中,执行:"CHANGE MASTER TO MASTER_LOG_FILE='log-bin.000004',MASTER_LOG_POS=106;",文件和位置对应master中的;
最后在slave中执行:"slave start;"来启动同步。
