Slave_IO_Running: No 一方面原因是因为网络通信的问题也有可能是日志读取错误的问题。以下是日志出错问题的解决方案：
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：从机器停止slave
mysql> slave stop;
到master机器登陆mysql：
记录master的bin的位置，例如：mysql> show mster status;+-------------------+----------+--------------+-------------------------------------------+| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |+-------------------+----------+--------------+-------------------------------------------+| mysqld-bin.000010 | 106 | | information_schema,mysql |+-------------------+----------+--------------+-------------------------------------------+日志为mysqld-bin.000010
刷新日志：mysql> flush logs;
因为刷新日志file的位置会+1，即File变成为:mysqld-bin.000011
马上到slave执行
mysql> CHANGE MASTER TO MASTER_LOG_FILE=‘mysqld-bin.000011‘,MASTER_LOG_POS=106;
mysql> slave start;
mysql> show slave statusG;
