數(shù)據(jù)庫無法啟動(dòng)，今天無緣無故啟動(dòng)不起來了。
手動(dòng)嘗試了很多的修改，還是無法啟動(dòng)
結(jié)果用官方的腳本解決了。
使用方法
在ssh輸入：wget -O sql-repair.sh http://download.bt.cn/install/sql-repair.sh && sh sql-repair.sh
運(yùn)行寶塔檢測(cè)腳本，然后可以排除錯(cuò)誤。一般來說可以啟動(dòng)數(shù)據(jù)庫了。
也可以自己創(chuàng)建一個(gè)腳本然后運(yùn)行，代碼如下
#!/bin/bash
