实验要求:

实验内容

设计与实现一个系统配置的 Shell 脚本。功能模块如下：

1 配置主机名、输出当前主机名、根据用户输入设置主机名

2 配置网络模块、备份当前的网络配置、自动配置网络为静态 IP 配置；

3 配置防火墙 l输出当前防火墙状态

根据用户选择配置防火墙：0为关闭防火墙；1 为开启防火墙；

4 本地光盘 yum 源 l备份当前所有的 yum 源配置；自动配置光盘为 yum 源；

5 重启模块 l所有配置完成后，自动重启系统使所有配置生效；

实验要求

1.配置备份存储在/root/backup-0707目录下；

2.每个模块分别通过一个函数实现；

3.详细给出函数和重要代码的说明；

4.给出测试过程及结果说明；

注意，此次涉及网卡为 eth0，请根据自身情况修改

Controller.sh如下

sh Hostname.shsh Network.shsh Firewalld.shsh Yum.shsh Reboot.sh

Hostname.sh如下

echo "@@@@@@@@@@@@@@@ This Is Hostname Set @@@@@@@@@@@@@@@"echo $HOSTNAMEread -p "Please set hostname:" hostnamehostnamectl set-hostname $hostnamebash

Network.sh如下
