生产服务器LNMP全自动安装脚本

【51CTO独家特稿】此脚本在生产服务器上使用了一年多，可以在任何一台有网络的服务器上自动配置LNMP。

使用方法：将nginx_php代码保存一个文件，例如nginx_php。上传到服务器上执行。

此脚本在CentOS 5.6 i386/x86_64环境下通过。

bash nginx_php出现提示，如下列图所示。

bash nginx_php提示

根据大家自己的需要选择数字中任意一个，开始全自动安装LNMP的世界中去吧。

如果之前安装过nginx或者 php 的话，脚本会自动检测它们是不是安装过。例如

就会提示nginx或者php 已经安装过了。

nginx_php 各部分功能讲述

不管安装nginx php和mysql，如果脚本检测系统没有执行脚本的时候，将会自动执行初始化工作（包括yum 安装相关组件和下载所有的软件包以及配置nginx php服务）

nginx_php里的函数init 表示初始化，分几步来执行初始化：

1） yum 安装nginx php mysql相关组件

2）在没有发现当前目录有packages的情况下， wget 下载软件包、配置文档、服务脚本到创建的packages下，之后删除软件列表。

3）设置nginx和php-fpm服务

4）创建eaccelerator 缓存目录/data0/cache,创建mysql数据目录/data0/mysql/data

5）将mysql bin路径加入系统PATH中。

6）创建myql组和mysql用户，www组和www用户

函数check_init表示，检测初始化工作有没有执行。

函数check_nginx表示，检测nginx有没有安装

函数check_php52表示，检测php有没有安装

函数check_mysql表示，检测mysql有没有安装

函数is_version表示，检测系统是64位的还是32位的，如果是64位的话，就安装libunwind库，因为google-perftools在64位系统中用到了libunwind库，在32位的是不需要安装libunwind库的。

函数ins_nginx表示安装nginx，其中有判断系统是否是64位，以便于顺利安装google-pertfools。

函数ins_mysqlclient表示安装mysql 客户端，这是让php 可以连接mysql server。

函数ins_mysqlserver表示安装mysql 服务端，并设置mysql安装目录为mysql组和mysql用户所有，已经配置mysql系统库。

函数ins_php52表示安装php，包括libiconv、autoconf、libmcrypt、mhash、mcrypt、suhosin等安装。并配置php.ini

函数ins_php52ext表示安装php的扩展，包括mecache、eacceletator、imagick等安装。
