問題描述

系統是 centos6.5 安裝的 AMH4.2 ，昨天下午網站始終打不開，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 一直關不了，等了好久都關不了，我一時心急，做出了一個錯誤的決定，關機重啟，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. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail.

現在才感覺到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？
