我們的備份服務(wù)器上運(yùn)行了一個(gè)

mysql復(fù)制客戶端.自上周停電以來,它已停止復(fù)制.在此之前,它連續(xù)幾個(gè)月沒有運(yùn)行.

我已經(jīng)嘗試重新啟動(dòng)主設(shè)備和從設(shè)備,但這沒有幫助.我可以從從服務(wù)器訪問主服務(wù)器,因此網(wǎng)絡(luò)不是問題.

還有什么我可以做的來嘗試診斷問題是什么嗎？

更新：錯(cuò)誤進(jìn)入daemon.log,而不是mysql.err,這可以解釋為什么我找不到它們.問題似乎是主人說日志不可用,這沒有多大意義,因?yàn)橹魅罩救匀豢梢允褂迷撊罩?和前一個(gè)日志).
