有客户需要让这次在Amazon CentOS7 AMI安装MySQL5.6.22。
centos用户登录到Amazon EC2服务器以后，sudo到root用户。
在CentOS7 AMI执行yum install mysql-server命令会发现无法安装mysql server。
# sudo su - # yum install mysql-server Loaded plugins: fastestmirror base | 3.6 kB 00:00 epel/x86_64/metalink | 5.5 kB 00:00 epel | 4.4 kB 00:00 extras | 3.4 kB 00:00 rpmforge | 1.9 kB 00:00 updates | 3.4 kB 00:00 epel/x86_64/primary_db | 3.8 MB 00:00 (1/2): epel/x86_64/updateinfo | 230 kB 00:00 (2/2): epel/x86_64/pkgtags | 1.3 MB 00:00 Loading mirror speeds from cached hostfile * base: www.ftp.ne.jp * epel: s3-mirror-ap-northeast-1.fedoraproject.org * extras: www.ftp.ne.jp * rpmforge: ftp.riken.jp * updates: www.ftp.ne.jp No package mysql-server available. Error: Nothing to do
因为，CentOS7的默认数据库是MariaDB。
1, 配置MySQL5.6的Repository
访问http://www.mysql.com/downloads/以后，点击「Downloads」→「Yum 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 Preparing... ################################# [100%] Updating / installing... 1:mysql-community-release-el7-5 ################################# [100%]
确认MySQL5.6yum源存在。

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
