**注意：如果是输入的是字母的或者是输入等于0时，则会出现以下两种情况！！！**

![70 2][]

**查看端口：**

![70 3][]

**进到[Nginx][]根目录查看创建好的测试网页：**

**注意：关闭防火墙或者设置防火墙规则！！！**

![70 4][]

**访问Nginx网页：**

![70 5][]

**访问PHP测试页：**

**访问地址：192.168.197.180/dog1.php**

![70 6][]

**访问MySQL测试页：**

**访问地址：192.168.197.180/dog2.php**

![70 7][]

**脚本代码如下：**

#!/bin/bash
    . /etc/init.d/functions
    MMM=`rpm -qa | grep mariadb`
    cat <<END

    |                                  |
    |         1.安装Nginx              |
    |         2.安装MySQL              |
    |         3.安装PHP                |
    |         4.配置LNMP环境           |
