Got fatal error 1236 from master when reading data from binary log: 'Could not find first log file name in binary log index file'
备库检查报错:

解决:
在 source 那边,执行:
flush logs; show master status;File
在 target 端,执行:
stop slave ; CHANGE MASTER TO MASTER_LOG_FILE='testdbbinlog.000008',MASTER_LOG_POS=107; start slave ; show slave status \G
一切正常。
