本脚本主要介绍lnmp+FastCGI平台的搭建脚本，需要准备的安装包如下：
cmake-2.8.10.2.tar.gz
libevent-2.0.21-stable.tar.gz
libmcrypt-2.5.8.tar.gz
mhash-0.9.9.9.tar.gz
nginx-1.2.0.tar.gz
php-5.4.9.tar.gz
libiconv-1.13.tar.gz
mysql-5.5.13.tar.gz
由于脚本需要，将上述安装包统一打包为lnmp+memcached.zip，使用时将该脚本放在该安装包相同的目录。
先安装依赖包，需要将yum源配好，在这里不再赘述，接下来是脚本内容：

yum clean all > /dev/null

echo "yum仓库配置异常，请检查yum配置"

echo "本脚本可安装nginx、mysql、php以及整体搭建lnmp平台，请输入要安装的服务。例如：sh nginx.sh lnmp";;
esac
该脚本使用时可以给脚本添加执行权限：
chmod +x lnmp.sh
此时直接使用./lnmp.sh 安装部分 即可执行安装，注意，此脚本需要指定要安装的部分，比如要安装mysql，则在执行时候输入./lnmp.sh mysql。
若在一台裸机上安装lnmp平台，则可以使用./lnmp.sh lnmp来全部搭建lnmp平台。
由于我们在安装时可能多次执行脚本，所以我们可以将脚本中使用yum安装部分单独保存为一个脚本，或者封装为一个函数，在脚本后添加一个case来调用。
