分享一个“一键安装LNMP脚本”

下载地址：http://down.51cto.com/data/872036

最近几天上班仍然没有什么事情做，一如既往的自己在那里学习，最近喜欢上了写shell脚本，之前一直想写，可是总没有充足的时间写，所以现在比较有空就赶紧写写，也当是复习一下。上周写了一键LAMP的脚本，这次写的是一键LNMP的脚本，之所以写这种脚本，是觉得部署的时候，有这么一个脚本，放上去跑一下就完事了，很方便，还是挺有意义的。接下来还会写一个一键按Nagios的脚本，现在已经写好了服务端的脚本，还差客户端。写完会马上分享出来的。当然，鉴于本人能力有限，经验也少，所以脚本写得不好，还请大家多多指正。

注意：
脚本运行环境如下：
1、Centos6.3 最小化安装
2、所使用的版本：
(1)mysql-5.5.31.tar.gz
(2)php-5.4.17.tar.gz
(3)nginx-1.4.1.tar.gz
注意：在执行脚本之前，需要先下载好以上3个软件包，并将脚本与上述包放在同一目录下。

下面就是我写的LNMP脚本：

#!/bin/bash
cat << EOF
