【Linux】疑難雜症@CentOS7.5 配置固定IP

• 1、檢視網卡名稱
• 2、編輯網卡配置檔案
• 3、重新開機網絡服務

1、檢視網卡名稱

[[email protected] ~]# ip addr

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

inet 127.0.0.1/8 scope host lo

valid_lft forever preferred_lft forever

inet6 ::1/128 scope host

valid_lft forever preferred_lft forever

2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000

link/ether 00:0c:29:55:7d:52 brd ff:ff:ff:ff:ff:ff

inet 192.168.18.212/24 brd 192.168.18.255 scope global noprefixroute ens33

valid_lft forever preferred_lft forever

inet6 fe80::cfb8:9c22:bff4:c2e3/64 scope link noprefixroute

valid_lft forever preferred_lft forever

2、編輯網卡配置檔案

IPV6_PRIVACY=“no”

IPADDR=192.168.18.212

NETMASK=255.255.255.0

GATEWAY=192.168.18.1

DNS1=192.168.1.2

DNS2=8.8.8.8

3、重新開機網絡服務

[[email protected] ~]# service network restart
