Hace unos días instalamos un servidor Ubuntu Linux (por requerimientos del software). Tuvimos que cambiar el nombre de host de ese equipo y aquí os dejamos cómo se hace.
Cambiar el hostname de un equipo Ubuntu.
Si sólo quieres cambiarlo sólo hasta el siguiente reinicio puedes poner:
hostname NUEVONOMBRE
Para hacerlo más permanente, tienes que editar dos ficheros.
- El fichero etc/hostname que es el que da el nombre al servidor. Hazlo con este comando, o con tu editor favorito
sudo vim /etc/hostname - El fichero etc/hosts que le dice dónde tiene que ir cuando pongan ese nombre. Es su DNS interno. Hazlo con este comando (o pon tu editor)
sudo vim /etc/hosts
No es necesario reiniciar aunque si muy conveniente (sudo reboot).
Puedes comprobar el cambio con los comandos hostname o
hostnamectl .
