Centos 5.8中用Shell脚本一键安装mysql 5.5.25源码包

最近在研究mysql集群，至少要安装部署2台或者多台mysql数据库，操作起来即麻烦又很耗时，今天根据安装步骤写了一个Shell脚本，只需执 行以下脚本就可以快速安装mysql数据库，对初学者或者想学习mysql集群的朋友非常方便，即省时，又省力。

操作系统及其mysql配置文件说明：

Linux系统：Centos5.8

mysql:mysql-5.5.25tar.gz源码包

安装目录：/usr/local/mysql/

数据目录：/data/mysql/3306/data/

二进制日志：/data/msyql/3306/binlog/

relay日志：/data/mysql/3306/relaylog/

配置文件：/data/mysql/3306/my.cnf

mysql.sock文件：/data/mysql/3306/mysql.sock

下面是我编写的一键安装mysql数据库的脚本，如有不对的地方请多多指教。
