1.修改/etc/sysconfig/network-scripts/eno16777736
查看你的網卡名稱(本機是eno16777736):
[root@linuxprobe Desktop]# ifconfig eno16777736: flags=4163 mtu 1500 inet 192.168.1.100 netmask 255.255.255.0 broadcast 192.168.1.255 inet6 fe80::20c:29ff:feb8:2b07 prefixlen 64 scopeid 0x20 inet6 fde0:b912:e3a9:0:20c:29ff:feb8:2b07 prefixlen 64 scopeid 0x0 ether 00:0c:29:b8:2b:07 txqueuelen 1000 (Ethernet) RX packets 37 bytes 5428 (5.3 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 62 bytes 8269 (8.0 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 0 (Local Loopback) RX packets 134 bytes 10928 (10.6 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 134 bytes 10928 (10.6 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 [root@linuxprobe Desktop]#
編輯ifcfg-eno16777736 文件：
紅色爲需要修改或者添加的內容,保存並退出。

重啓網卡並測試網絡：
[root@linuxprobe Desktop]# systemctl restart network
2.圖形工具nmtui
在終端執行命令：
[root@linuxprobe Desktop]# nmtui
你依然需要重啓網卡才能生效，並測試網絡。
3.圖形工具nm-connection-editor
終端執行命令：
[root@linuxprobe Desktop]# nm-connection-editor
