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-20190707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.sh
    sh Network.sh
    sh Firewalld.sh
    sh Yum.sh
    sh Reboot.sh

Hostname.sh如下

echo "@@@@@@@@@@@@@@@ This Is Hostname Set @@@@@@@@@@@@@@@"
    echo $HOSTNAME
    read -p "Please set hostname:" hostname
    hostnamectl set-hostname $hostname
    bash

Network.sh如下

echo "################ This Is Network Backup ####################"
    #echo "Please Input Your Interface name:"
    #read -p "Please Input Your Interface name:" itn
    
    grep "BOOTPROTO" /etc/sysconfig/network-scripts/ifcfg-eth0   ##此处eth0为我的网卡名，请根据自身实际情况修改
    state=`grep "BOOTPROTO" /etc/sysconfig/network-scripts/ifcfg-eth0`
    echo "This is your Interface state:$state"
    echo "如果你的网卡为stastatic模式，请手动设置，切勿使用脚本"
    echo "Please Input Your IP/GATEWAY/NETMASK/DNS"
    
    read -p "Please Input Your IP:" iP
    echo "IPADDR=$iP" >> /etc/sysconfig/network-scripts/ifcfg-eth0
    read -p "Please Input Your GATEWAY:" gT
    echo "GATEWAY=$gT" >> /etc/sysconfig/network-scripts/ifcfg-eth0
    read -p "Please Input Your NETMASK:" nT
    echo "NETMASK=$nT" >> /etc/sysconfig/network-scripts/ifcfg-eth0
    read -p "Please Input Your DNS:" dN
    echo "DNS1=$dN" >> /etc/sysconfig/network-scripts/ifcfg-eth0
    
    echo "Restarting Networking......"
    systemctl restart network

Firewalld.sh如下

echo "############ This Is Firewalld Set ###################"
    systemctl status firewalld
    echo "************this is firewalld state set(only input 1 char,like 1 or 0)"
    echo "0:Stop the firewalld"
    echo "1:Start the firewalld"
    read -n 2 -p "Please choose your Firewalld state:" state
    echo -e "\n"
    if [ $state -eq 0 ];then
    systemctl stop firewalld
    systemctl status firewalld
    elif [ $state -eq 1 ];then
    systemctl start firewalld
    systemctl status firewalld
    echo -e "\n"
    else
            echo "Error!"
    fi

Yum.sh如下

echo "^^^^^^^^^^^^^^^^this is yum backup test^^^^^^^^^^^^^^"
    mkdir -p /root/backup-20190707/yums/
    cp /etc/yum.repos.d/* /root/backup-20190707/yums/
    rm -rf //etc/yum.repos.d/*
    echo "[centos]" > /etc/yum.repos.d/local.repo
    echo "name=centos" >> /etc/yum.repos.d/local.repo
    echo "baseurl=file:///opt/centos" >> /etc/yum.repos.d/local.repo
    echo "gpgcheck=0" >> /etc/yum.repos.d/local.repo
    echo "enabled=1" >> /etc/yum.repos.d/local.repo
    mount /dev/cdrom /mnt/
    mkdir -p /opt/centos
    cp /mnt/* /opt/centos
    yum list

Reboot.sh如下

echo "%%%%%%%%%%%%%% This is Reboot Program %%%%%%%%%%%%%"
    echo "Please input your choose:"
    echo "1:Reboot your System , and make your change Take Effect"
    echo "2:Give Up Reboot"
    read -n 2 -p "Please input your choose:" rb
    if [ $rb -eq 1 ];then
    reboot
    elif [ $rb -eq 2 ];then
    echo "Give up reboot,Think........"
    else 
    echo "Error Input Number"
    fi
