此脚本可实现执行一次全自动无从守护搭建lnmp环境,执行完成后,PHP、nginx、MYSQL、以及一些库文件均安装在/usr/local/目录下。如果第一次搭建lnmp环境,最好还是手动装一遍。
此脚本参考张宴的Nginx 0.7.x + PHP 5.2.8(FastCGI)搭建胜过Apache十倍的Web服务器,地址: http://blog.s135.com/post/366/ ,可以前往了解,对更好配置lnmp环境也有好处。
把所以需要的软件下载好(可以到官网下载,也可以到张宴博客下载)与shell脚本配置文件放到一个名为lnmp的文件夹内。
新建一个名为install.sh文件,加上可执行权限,代码如下
- #!/bin/bash
- #升级所需要的库文件,编译工具……

以上代码经本人测试可以无错误地在centOS5.5、centOS5.6环境下安装,如果安装到其它环境或者用新版软件,最好在每一步安装一个软件后写上如下代码,以免出错提示,如第6、7行,如果安装正解,系统参数$?应该为0,否则为安装出错。
