Centos7 安装Mysql 然而mysql-server 安装失败的问题

解决办法：

1. 下载mysql的repo源

$ wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

2. 安装mysql-community-release-el7-5.noarch.rpm包

$ rpm -ivh mysql-community-release-el7-5.noarch.rpm

安装这个包后，会获得两个mysql的yum repo源：/etc/yum.repos.d/mysql-community.repo，/etc/yum.repos.d/mysql-community-source.repo。

3. 安装mysql

$ yum install mysql-server

执行：

yum install mysql-devel gcc gcc-devel python-devel
