問題描述

系統(tǒng)是 centos6.5 安裝的 AMH4.2 ，昨天下午網(wǎng)站始終打不開，于是我想重啟 MySQL ，用 amh 自帶的命令： amh mysql 然后選擇 restart ，但是，那個 MySQL 一直關(guān)不了，等了好久都關(guān)不了，我一時心急，做出了一個錯誤的決定，關(guān)機重啟，重啟之后， amh 的 nginx 和 php 能正常啟動，就是 MySQL 一直啟動不了，我用 amh mysql 命令，選擇了 start ，始終顯示這個錯誤信息：

[AMH] MySQL Management please select: (1~6) 1) start 3) restart 5) force-reload 2) stop 4) reload 6) exit

Starting MySQL.The server quit without updating PID file (/[FAILED]l/mysql/data/ns471333.eu.pid). 把網(wǎng)上的做法全部試完了都不行，比如這個帖子里面的： http://stackoverflow.com/ques... 比如刪除錯誤的err文件，刪除my.cnf文件都試過了，始終啟動不了

求 MySQL 高手解疑一下吧，謝謝，謝謝 ，真的快急死人了

這是error.log信息： 160810 00:15:00 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data 160810 0:15:00 [Note] Plugin ’InnoDB’ is disabled. 22:15:00 UTC - mysqld got signal 11 ; This could be because you hit a bug.

現(xiàn)在才感覺到MySQL是如此脆弱不堪一擊，如果要重裝MySQL，怎樣在AMH4.2中重裝MySQL？

This could be because you hit a bug.程序已經(jīng)提示或許是bug導致的
