CentOS7修改网卡DHCP获取IP为静态IP

1.修改网卡配置

[root@centos7 ~]#cd /etc/sysconfig/network-scripts/

[root@centos7 network-scripts]#vi ifcfg-eth0

TYPE=Ethernet

PROXY_METHOD=none

BROWSER_ONLY=no

BOOTPROTO=static       #修改为static

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=eth0

UUID=048802a8-f20c-4c19-902a-e326b3a69686

DEVICE=eth0

ONBOOT=yes                      #修改网卡随系统自启动

IPADDR=192.168.155.10      #修改为指定IP

NETMASK=255.255.255.0    #掩码

GATEWAY=192.168.155.1    #网关

2.重启网卡服务

[root@centos7 network-scripts]# systemctl restart network

3.验证网卡IP

重启后，重新连接查看网卡信息

[root@centos7 ~]# ifconfig
