Centos7下DHCP搭建

准备两台虚拟机，一位服务端，一为客户端
服务端：
更改VMware的配置

点击编辑中的虚拟网络编辑器，

服务端

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33 
[root@localhost ~]# systemctl restart network
[root@localhost ~]# ifconfig

安装dhcp并修改配置文件

[root@localhost ~]# yum -y install dhcp
[root@localhost ~]# cp /usr/share/doc/dhcp*/dhcpd.conf.example /etc/dhcp/dhcpd.conf
cp: overwrite ‘/etc/dhcp/dhcpd.conf’? y
[root@localhost ~]#  vim  /etc/dhcp/dhcpd.conf

开服务，关闭防火墙，降低沙盒等级

[root@localhost ~]# systemctl restart dhcpd
[root@localhost ~]# setenforce 0
[root@localhost ~]# systemctl stop firewalld

服务器验证

网卡配置

[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens33
[root@localhost ~]# systemctl restart network

重新分配IP

[root@localhost ~]# dhclient -r ens33
[root@localhost ~]# dhclient
[root@localhost ~]# ifconfig

搭建成功
