centos6.8编写shell脚本实现自动化搭建安装LNMP平台全过程配置详解
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!!!
查看端口:
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!!!
访问Nginx网页:
访问PHP测试页:
访问地址:192.168.197.180/dog1.php
访问MySQL测试页:
访问地址:192.168.197.180/dog2.php
脚本代码如下:
#!/bin/bash
. /etc/init.d/functions
MMM=`rpm -qa | grep mariadb`
cat <<END
+----------------------------------+
| |
| This is a LNMP |
| |
| 1.安装Nginx |
| 2.安装MySQL |
| 3.安装PHP |
| 4.配置LNMP环境 |
