系统环境：CentOS 7.4

1.静态IP

Step 1：配置IP地址、子网掩码
vi /etc/sysconfig/network-scripts/ifcfg-ens33

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=4761957a-4094-451f-9c44-6b757dfb1c6b
DEVICE=ens33
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.1.101
NETMASK=255.255.255.0

Step 2：配置网关
vi /etc/sysconfig/network

# Created by anaconda
GATEWAY=192.168.1.1

Step 3：配置DNS
vi /etc/resolv.conf

# Generated by NetworkManager
nameserver 192.168.1.1
nameserver 8.8.8.8
nameserver 114.114.114.114

2.动态IP

配置动态IP仅需设置dhcp即可
vi /etc/sysconfig/network-scripts/ifcfg-ens33

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=4761957a-4094-451f-9c44-6b757dfb1c6b
DEVICE=ens33
ONBOOT=yes

修改配置以后，记得使用systemctl restart network重启网络服务。
