CentOS7修改網(wǎng)卡DHCP獲取IP為靜態(tài)IP
1.修改網(wǎng)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?????? #修改為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????????? ? ? ? ? ? ? #修改網(wǎng)卡隨系統(tǒng)自啟動
IPADDR=192.168.155.10????? #修改為指定IP
NETMASK=255.255.255.0??? #掩碼
GATEWAY=192.168.155.1 ?? #網(wǎng)關
2.重啟網(wǎng)卡服務
[root@centos7 network-scripts]# systemctl restart network
3.驗證網(wǎng)卡IP
重啟后，重新連接查看網(wǎng)卡信息
[root@centos7 ~]# ifconfig
