The slave I/O thread stops because master and slave have equal MySQL server ids; these ids must be different for replication to work (or the --replicate-same-server-id option must be used on slave but this does not always make sense; please check the manual before using it).
这个错误信息翻译成中文就是,master和slave有相同的 mysql server id,只有id不同,才可以复制才能运转起来
