Linux host name modification command

Linux host name modification command

1. If you only need to temporarily change the host name, you can use the hostname command.

sudo hostname <new-hostname>
# 例如:
sudo hostname myDebian

This command will not change the static hostname (static hostname) in the /etc/hostname file, it only changes the temporary hostname (transient hostname). So after restarting the computer it will go back to the old hostname.

2. If you want to permanently change the host name, you can use the hostnamectl command, or use vim to manually modify the /etc/hostname file

command syntax For:

sudo hostnamectl set-hostname <newhostname>
# sudo vim /etc/hostname

This command will delete the host name in the /etc/hostname file and replace it with the new host name.
