因为要解析PHP页面需要配置相应的PHP环境，而系统本身的php版本又大多不合适。网上那种一键lamp和lnmp的脚本很多，但是这样一来自己能够定制的空间则少了。所以我自己编写了个门用于安装php环境的脚本！

脚本内容：

#!/bin/bash

if [ $(id -u) != 0 ] ;then

        echo "ERROR: you must be root to run this script"

        exit 1

fi

read -p "Are you ready to installing the new PHP environment ?you can input ‘y|Y‘ to continue or ‘n|N‘ to exit." choice

case $choice in

[Yy])

echo "The setup program is preparing,please wait a minute........"

ping -c 4 museum.php.net &> /dev/null

if [ $? != 0 ];then

        echo "Can‘t connected to the internet or can‘t resolve domain name,please check your network"

        exit 2

fi

yum install epel-release -y

which wget &> /dev/null

if [ $? != 0 ];then

        echo "wget not exist,please install wget before install"

        exit 3

fi

while true;do

read -p "Please input which version of PHP do you want to install like x.x.x:" version

if [[ $version =~ ^[0-9]\.[0-9]\.[0-9]$ ]];then

        wget museum.php.net/php${version:0:1}/php-${version}.tar.gz

        if [ $? != 0 ] ;then

                echo "You choose a wrong version of PHP,please input another version for install^-^!"

                exit 8

        fi

        break

else

        echo "Please input correct version of number"

fi

done

echo "Start to installing dependent environment!"

        sleep 3
