How to set a fixed IP in Linux (tested and effective)

First, open the virtual machine

Open xshell5 to connect to the virtual machine (more convenient, the Linux ip is set by default here, but it is not fixed)

Enter ifconfig to view network management related configuration information:

Then enter the vi /etc/sysconfig/network-scripts/ifcfg-ens33 command. Modify the network card configuration file

Press i to edit. Make the changes below. Do not delete the original configuration, just modify it as follows. Just add the configuration items that are not available.

After opening it, you can see that the default configuration is DHCP, and then onboot=no, which means it will not start when the system starts. We need to modify this configuration

Then create two values ​​ip and subnet mask below and add them to any position in the above picture.

IPADDR=192.168.0.116 (fill in your IP address) #IP address

NETMASK=255.255.255.0 (fill in your mask value) #Mask value

GATEWAY=192.168.0.1 (default gateway)

DNS1=8.8.8.8 (using Google's default DNS server)

If the above 4 items are not available, add them. If they are available, modify them (configure as shown above, and delete other parameters, they are useless)

Esc to exit editing, :wq to save and exit, reboot to restart

After restarting, enter ifconfig to check whether the IP modification is successful.
