Centos7的yum安装mysql而不是 mariadb
那一天，开发的让运营这边帮忙布个环境，我义不容辞地接了下来。然后，在centos7上一遍yum，把所有的LAMP 搞定了，正当我觉得完事时，可故事从现在才开始。
开发组要的是纯正的mysql，孤陋寡闻的我也知道MariaDB是mysql的一个分支。
当时太兴奋，也没看安装提示直接就填了yes，等安装完傻眼了，Centos7的默认yum源装的竟然是MariaDB。
好比，开发组明明要的是可口可乐，我要是给他们被凉茶，他们肯定一口凉茶把我喷的。

A．到MySQL yum库的下载页面https://repo.mysql.com/
B．找一个跟自己平台匹配的发行包，用uname命令看看自己的平台版本
C . 用wget命令把相应的rpm包下下来，这个包很小只有几k

事不宜迟，马上安装（安装前记得要清掉缓存，而且mariadb 一定要删干净）
