论如何在西部开源偷懒之自动修改静态ip

改ip又繁琐又重复，搭建服务必须要做，作为懒虫，我有一句mmp必须要讲
如果你也想偷懒你需要我来给你安排一下

想学习手动修改的不准点这里

话不多说，上代码

#!/bin/bash
read -p "请输入网卡名：" name
touch /etc/sysconfig/network-scripts/ifcfg-$name
while true
do

	echo -e "
\033[32m a=all \033[0m
\033[32m ag=add gateway \033[0m
\033[32m dg=dele gateway \033[0m
\033[32m q=quit \033[0m
\033[32m 以此类推 \033[0m
\033[32m 不输入网关按回车可回到主菜单 \033[0m
		\033[31m a 查看配置文件 \033[0m
		\033[31m b 清除所有设置并修改ip \033[0m
		\033[32m ag 添加gateway \033[0m
		\033[33m dg 删除gateway \033[0m	
		\033[34m ad 添加dns \033[0m
		\033[35m dd 删除dns \033[0m	
		\033[36m q 退出 \033[0m

复制好了没有，来阿快活起来！

首先sh 它
按照提示首先输入网卡硬件的名称

按顺序来，输入a可以看现有的配置文件内容

什么乱七八糟的配置，我们来输入b来清空原有配置并且创建我们想要的ip，输入后按回车上车

ag添加gateway同样按回车上车

dg删除gateway

剩下的我不写了，不为什么，我懒

哎别别别开玩笑的

我都道歉了你考虑一下关注咯～
之后会陆续推出第一本书自动搭建服务的脚本
