之前按Freehao123的教程弄來了一個永久VPS，不過內存才128，所以不得已給VPS裝上了N年更新的VPSMate面板。

安裝VPSMate超級快，沒想到128的VPS不用10分鐘也能搞定，之前用384的裝個WDCP也要半小時，不過相比之下，VPSMate功能實在太弱了，而且小問題不斷

先是安裝PHP的時候提示軟件IUS源安裝失敗，搜索出錯信息發現是源失效了，連SSH手動裝個就行，但是到安裝完MySQL之後發現MySQL不能正常啟動。

翻看Log

什麼都不懂，搜索相關字眼也沒找到解決辦法(後來發現Log中就有解決辦法)，就在幾個小時前，不知如何的鬼使神差，進入的pany.asia，然後發現第一篇博文就是解決這個問題的。

解决方法如下

  1. 在my.cnf中添加在mysqld的部分 "innodb_use_native_aio=0"

  2. 接下來在SS​​H中運行運行# service mysqld start
  3. mysql成功啟動。
