1、配置主机名，IP地址[root@server ~]# hostnamectl set-hostname server.linux.com （配置主机名）[root@www ~]# cat /etc/sysconfig/network-scripts/ifcfg-eno33554984（修改静态IP）TYPE=EthernetBOOTPROTO=noneNAME=eno33554984（网卡名）ONBOOT=yes(开机自启)IP=172.16.87.101NETMASK=255.255.255.0（子网掩码）GATEWAY=172.16.87.254（网管）DNS1=202.106.0.20DNS2=114.114.114.114[root@server ~]# systemctl restart network（重启网络）[root@server ~]# systemctl restart NetworkManager
2、安装软件yum install -y dhcp(安装软件)systemctl start dhcpss -antp | grep DHCP（查看软件是否启动成功）
3、编辑配置文件 [root@server ~]# vim /etc/dhcp/dhcpd.conf subnet 172.16.87.0 netmask 255.255.255.0{ range 172.16.87.10 172.16.87.20; option routers 172.16.87.254; option domain-name-servers 202.106.0.20;}subent（网段） netmask（子网掩码） range（IP分配范围）option（网管） option domain-name-servers (dns)
4、启动systemctl start dhcpd（q）systemctl restart dhcpd（重启）测试ping 172.16.87.10（IP分配范围）
