1.服務端
（1） 配置服務器爲ip靜態
1.通過圖形修改 ：nm-connection-editor
2.配置Yum源
cd /etc/yum.repos.d
ls
vim rhel_dvd.repo 配置yum源
yum inatll dhcp 安裝dhcp
yum clean all 清空yum緩存
3.vim /etc/dhcp/dhcpd.conf 查看配置文件
cp /usr/share/doc/dhcp/dhcpd.conf.example(配置文件模板) 複製配置文件模板到/etc/dhcp/dhcpd.conf
5.vim /etc/dhcp/dhcpd.conf 修改配置文件
**編輯內容**

33 option routers 172.25.254.250; 客戶主機獲得的網關
客戶端
1.編輯配置文件修改dhcp：vim /etc/sysconfig/network-scripts/ifcfg-eth0
將BOOTPROTO=dhcp
2.systemctl restart network 重啓服務獲得ip
3.3.ifconfig **查看ip
