This article is about how linux modifies hostname. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Method: 1, use "hostname modified hostname" statement to modify hostname, server restart will be invalid; 2, use "vim / etc/sysconfig/network" statement to modify hostname, server restart will be permanently effective.

The operating environment of this tutorial: linux7.3 system, Dell G3 computer.

1. If you just modify hostname, you can use the following command

Hostname newHostname

Note: this modification method is only currently valid. After the server is restarted, the hostname will become invalid and return to the original hostname.

2. If you need to modify hostname permanently, you can use the following command

Vim / etc/sysconfig/network

Modify the HOSTNAME entry, but this method will take effect after reboot.

3. Therefore, the way to permanently modify hostname without restarting is to combine the above two methods, so that it will take effect without reboot for the current time and after reboot.
