It is very suitable for beginners to learn and is worth reading. Interested friends can follow the editor to read together. I hope you can get something through this article!

After we have installed the Linux system (Centos system), each login requires our own manual networking, which is more troublesome.

First, after logging in, set the ip to be obtained automatically through the page (the ip obtained is random)

Procedure:

1. Click on the system, preferences, web links

two。 Click to select System eth0 in the real interface, and click Edit

3. Check the automatic link, and then click apply

Restart the system after the setup is complete and you can see the automatic link to ip, but this mode does not apply to the server because the server ip is fixed.

Second, specify a fixed ip address: specify Ip directly by modifying the configuration file, and edit vim / etc/sysconfig/network-scripts/ifcfg-eth0

All the information of our network configuration is in ifcfg-eth0 (0 represents the first network card and ifcfg-eth2 if there is a second one)

Case: configure the ip address to be static and the ip address is 192.168.152.111

1. Enter * * vim / etc/sysconfig/network-scripts/ifcfg-eth0** at the terminal

If the content displayed is not circled on the picture, it needs to be added.

two。 Then change the content as shown in the figure (everyone's ip and gateway may be different. You need to check your own ip before you modify it. )

3. Save the content modified above

4. Enter service network start at the terminal (used to update the network configuration)

5. Finally, enter ifconfig in the terminal to check whether the modification is successful.

What are the versions of Linux? the versions of Linux are Deepin, UbuntuKylin, Manjaro, LinuxMint, Ubuntu and so on.
