排障集锦：九九八十一难之第十一难！mysql 主从同步 Last_IO_Error: Got fatal error 1236 from master

mysql5.7设置主从同步

报错如下

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’

解决思路

stop slave; 关闭slave

reset slave; 重新更新slave

start slave 再次更新
