Error: Nothing to do
因为，CentOS7的默认数据库是MariaDB。
1, 配置MySQL5.6的Repository
选择Red Hat Enterprise Linux 7 / Oracle Linux 7 (Architecture Independent), RPM Package的「Download」
在这里会显示登录Oracle的页面，但是不必登录，拷贝No thanks, just start my download.的链接就可以。
拷贝的链接是：http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
配置MySQL5.6的yum源。
# rpm -ivh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
Retrieving http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

2, 安装MySQL
# yum install mysql-server
# mysql --version
mysql Ver 14.14 Distrib 5.6.22, for Linux (x86_64) using EditLine wrapper
成功的在Amazon CentOS7 AMI上安装了MySQL5.6.22。
小结
CentOS7，好像有不少改变呀。好像service命令变为systemctl命令了。
# service mysqld stop
Redirecting to /bin/systemctl stop mysqld.service
