1、搭建DCHP服务 ，给客户端自动分配IP
1.1 配置地址
vim /etc/sysconfig/network-scripts/ifcfg-ens33
1.2 关闭防火墙
systemctl stop firewalld
1.3 启动network服务
systemctl start network
ifconfig
2.挂载系统光盘镜像
mount /dev/cdrom /mnt/
ls /mnt/
3。使用rpm 安装dhcp服务软件包
rpm -ivh /mnt/Packages/dhcp-4.2.5-47.el7.centos.x86_64.rpm
3.1 编辑dhcp服务配置文件
vim /etc/dhcp/dhcpd.conf
4.启动dhcp服务
systemctl start dhcpd
4.1查看dhcp服务状态
systemctl status dhcp
5.查看dhcp服务的网络状况
netstat -anpt | grep dhcpd
netstat -anpu | grep dhcpd
