**Setup Hostname**
|
|
|
|
Log into the hostname (ssh)
|
|
|
|
Run the following command
|
|
|
|
```
|
|
sudo hostnamectl set-hostname NewHostName
|
|
```
|
|
|
|
Also need to update the hosts name
|
|
|
|
```
|
|
sudo vi /etc/hosts
|
|
```
|
|
|
|
***Example of old host file***
|
|
|
|
```
|
|
127.0.0.1 localhost
|
|
127.0.1.1 old-hostname.vocus.co.nz old-hostname
|
|
|
|
# The following lines are desirable for IPv6 capable hosts
|
|
::1 localhost ip6-localhost ip6-loopback
|
|
ff02::1 ip6-allnodes
|
|
ff02::2 ip6-allrouters
|
|
```
|
|
|
|
***Example of updated host***
|
|
|
|
```
|
|
127.0.0.1 localhost
|
|
127.0.1.1 New-hostname.vocus.co.nz New-hostname
|
|
|
|
# The following lines are desirable for IPv6 capable hosts
|
|
::1 localhost ip6-localhost ip6-loopback
|
|
ff02::1 ip6-allnodes
|
|
ff02::2 ip6-allrouters
|
|
|
|
```
|
|
|
|
While hostnamectl typically applies the changes immediately, some services or applications might still be referencing the old hostname. You can restart network services or reboot the system for a complete refresh, although often it's not strictly necessary.
|
|
To restart network services:
|
|
|
|
```
|
|
sudo systemctl restart network-online.target
|
|
```
|
|
|
|
or just reboot
|
|
|
|
```
|
|
Sudo Reboot
|
|
``` |
