Rename Host Machine
Rename a host machine
When working with Linux based systems it may be required to rename a host machine. This can be done using the following commands.
- Use hostnamectl to change the host name
hostnamectl set-hostname "new-hostname"
- Can also set the pretty, or display, name with the same tool
hostnamectl set-hostname "new pretty name" --pretty
Example
Rename the host machine ubuntu to ubuntu2
hostnamectl set-hostname "ubuntu2"
