本文为centos7.3自动化编译安装mysql5.3.6的脚本及后续初始化操作，话不多少，直接上脚本。
安装脚本install.py如下：

使用方法：
1.操作系统需要配置yum源
2.操作系统版本：centos7.3
3.将install.py my.cnf 和mysql安装包放一个文件夹
mysql安装包下载地址：链接: https://pan.baidu.com/s/1pKHbFlh 密码: tx9b
初始化
由于默认情况下编译安装的mysql5.6.36没有密码，命令行直接输入mysql进行登陆，执行以下sql语句
-- 初始化数据
use mysql;
update user set password=PASSWORD("Abcd123") where user='root';
grant all privileges on *.* to weihu@"%" identified by "Abcd123";
delete from mysql.user where user = '';
FLUSH PRIVILEGES;
-- 创建demo数据库
CREATE DATABASE `demo` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
show databases;
