機子是centOS6.5，於是首先檢視軟體庫中有沒有擴充套件：yum search php-mysql

既然有那就開始安裝擴充套件吧：yum install php-mysql
dang，出現瞭如下錯誤

仔細分析，原來是之前安裝過MySQL5.7，現在安裝的MySQL-libs是5.1版本，所以相容出現了問題
解決
感謝熱心網友，發現可以使用MySQL-shared-compat來解決這個相容性問題
首先訪問 http://rpm.pbone.net/index.php3?stat=3&search=MySQL-shared-compat&srodzaj=3&dist%5B%5D=52

點選圖中箭頭處

然後想辦法拿到下圖中的連結

 下載，

 然後安裝

接下來，你就可以正常的安裝yum install php-mysql 了，因為已經解決了相容性的問題了。
