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
