有过MySQL运维的人应该都清楚，线上的MySQL一般都采用源码编译，因为这样才可以根据企业的各自需要选择要编译的功能，虽然MySQL的源码编译挺简单的，但是试想一下，如果你有几百台服务器同时要安装MySQL，难道你还一台台去手动编译、编写配置文件吗？这显然太低效了，本文讨论MySQL的自动化安装部署。
wget http://downloads.mysql.com/archives/get/file/mysql-5.6.16.tar.gztar -zxvf mysql-5.6.16.tar.gzcd mysql-5.6.16mkdir rpmcd rpm在上面我们获取了源码，并在源码主目录下创建rpm目录，接着我们在该目录下创建mysql.spec文件：
