Steps for Installing Virtualmin on Webmin (Ubuntu):
- Setting the hostname and FQDN
For Virtualmin to work properly, you need to configure the hostname and FQDN on the server itself by editing the /etc/hostname and /etc/hosts files, as well as update your DNS settings so DNS lookups resolve properly.
First, log in to your server as your non-root user. Once you have logged in, update the package database:
# sudo apt-get update
Then install any necessary updates and packages to ensure you start with a stable and up-to-date system.
# sudo apt-get dist-upgrade –y
Next, change the hostname to match the FQDN you’ve pointed to the server in the prerequisites.
To check the current server hostname, run this command:
# hostname –f
To change the hostname of the server
# nano /etc/homename
Use just the hostname, not the entire FQDN, in this file. For example, if your FQDN is virtualmin.example.com, enter Virtualmin in this file.
Save the file and exit the editor.
Next, add both the hostname and FQDN in the /etc/hosts file:
# sudo nano /etc/hosts
Modify the line that starts with 127.0.0.1 to use your FQDN and hostname
Remember to replace your hostname and your_domain.com with your own hostname and domain name. Save the file and exit the editor.
To check if the name has been changed correctly, restart the server
# sudo reboot
Next, edit the network configuration file so that it uses this server as one of the DNS servers to resolve domain names. Open the configuration file:
# sudo nano /etc/network/interface.d/50-cloud-init.cfg
Look for dns-nameservers 8.8.8.8 8.8.4.4 – change it to 8.8.8.8 8.8.4.4 127.0.01 – save and exit editor
