本文为大家分享了Linux环境下mysql5.6.24自动安装脚本代码，供大家参考，具体内容如下
说明：
一、本脚本仅供测试使用，若正式环境想要使用，需更改脚本的一些参数。
二、使用本脚本之前，需保证linux环境可以联网下载，若不能联网，则需要将下载好的mysql二进制包上传至linux中的/data目录下。
三、脚本使用是需一次输入三个参数：
1、需安装的mysql版本号，如：5.6.24
2、需安装的mysql端口设置，如：3306
3、mysql的server_id设置，如：1003306
使用步骤：
1、将下列脚本上传至linux环境中，我个人是以mysql_install.sh命名

至此，linux下mysql安装已经完成，可以使用它做一些测试了。
