vi /etc/sysconfig/network-scripts/ifcfg-ens33

TYPE=Ethernet
PROXY_METHOD=static
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=13acf4da-111f-4b61-84cd-348d9442784e
DEVICE=ens33
ONBOOT=yes
IPADDR= 设置静态ip
GATEWAAY=网段最后为2
NETMASK=255.255.255.0 子网掩码

4.重启网卡并验证IP

service network restart
