MySQL 源码编译安装

脚本须知：

　　1. 该脚本目前只测试过mysql版本为5.6.x的源码，其他源码可以对本脚本稍作修改即可

　　2. 本脚本也可以使用wget mysql源码的方式进行，但考虑到后期提供源码的地址不可用，所以需要手动下载mysql 5.6.x的源码包并放入到/usr/local/src

　　3. 此脚本在编译安装过程中禁用了iptables和SElinux策略，如果你在使用iptalbes相关功能请先完成相关配置。

　　4. 该脚本主要是对此前尚未装过mysql的linux系统环境而写的，如果此前装过mysql请根据脚本适当修改，主要是在脚本添加判断语句，或者你也可以移除之前的mysql

　　    版本 （mysql安装路径 配置文件）

5. 本脚本实现的主要功能是mysql 安全初始化安装；提供sysv风格的启动脚本；最基本的配置文件（你可以根据功能需要通过配置然后覆盖/etc/my.cnf实现定制）

　　6. mysql 5.6.30源码编译安装 默认没有开启查询缓存，你可以在my.cnf 通过此选项 query_cache_type = ON 来启用
