環(huán)境是兩臺(tái)服務(wù)器做的主主備份,A服務(wù)器從B服務(wù)器同步的時(shí)候會(huì)遇到狀態(tài)都正常就是A服務(wù)器的Read_Master_Log_Pos和B服務(wù)器的不一致,相差200多萬, B服務(wù)器從A服務(wù)器復(fù)制一切正常.

相關(guān)信息如下:

Slave_IO_Running 和 Slave_SQL_Running 都正常只有pos出現(xiàn)不一致的問題

目前臨時(shí)解決辦法是在A服務(wù)器上stop slave然后start slave就好了,重啟slave就會(huì)進(jìn)行同步.
