redhat8如何配置静态IP
1、系统
[root@localhost ~]# cat /etc/redhat-release Red Hat Enterprise Linux release 8.5 (Ootpa)
2、进入/etc/sysconfig/network-scripts/目录,编辑目录下网卡配置文件:
[root@localhost ~]# cd /etc/sysconfig/network-scripts/ ## 进入该目录 [root@localhost network-scripts]# ls ## 列出网卡配置文件 ifcfg-ens160
3、使用vim编辑器编辑网卡配置文件,保存退出:
[root@localhost network-scripts]# vim ifcfg-ens160
TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static ## 由dhcp改为static DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no NAME=ens160 UUID=0989a9ce-60bb-4ae7-b857-0e9861ab5311 DEVICE=ens160 ONBOOT=yes ## 改为yes IPADDR=192.168.3.33 ## ip NETMASK=255.255.255.0 ## 子网掩码 GATEWAY=192.168.3.1 ## 网关 DNS1=8.8.8.8 ## DNS服务
4、将网络模式调整为桥接模式
5、查看当前网络配置
[root@localhost network-scripts]# ifconfig | head ens160: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 ether 00:0c:29:a6:91:1b txqueuelen 1000 (Ethernet) RX packets 1 bytes 247 (247.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host>
6、重启网络服务
[root@localhost network-scripts]# nmcli c reload [root@localhost network-scripts]# nmcli c up ens160 Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/4)
7、查看网络,IP已经生效
[root@localhost network-scripts]# ifconfig | head
