How to Install Virtualmin on FreeBSD 14.0

Published on September 20, 2024•Updated on November 21, 2023

Introduction

Virtualmin is an open-source web hosting control panel for managing virtual hosts, domains, email accounts, databases, and applications using a web-based graphical user interface (GUI). Virtualmin supports multiple database types, such as MySQL, PostgreSQL, and MariaDB.

This article explains how to install Virtualmin on FreeBSD 14.0 and enable access to the graphical web administration interface.

Prerequisites

Before you begin:

Deploy a FreeBSD 14.0 instance on Vultr.
Create a new domain A record pointing to the instance's public IP address such as virtualmin.example.com.
Access the instance using SSH as a non-root user with sudo privileges.
Update the instance.

Install Virtualmin

Virtualmin does not support automatic installation scripts on FreeBSD 14.0, but supports manual installations and configuration of all dependency packages. Follow the steps below to install Virtualmin using the latest FreeBSD Ports package and configure the Webmin package to run the application on your server.

Update the package information index.
console
```
$ sudo pkg update
```

Install Virtualmin.

                            console
                            
$ sudo pkg install -y sysutils/virtualmin

Output:

Message from virtualmin-7.2,1:

--
You will have to manually grant user permissions to access this
module from Webmin.

Configure the Webmin directories, paths, ports, administrator, and the SSL certificate.

                            console
                            
$ sudo sh /usr/local/lib/webmin/setup.sh

Output:

***********************************************************************
        Welcome to the Webmin setup script, version 2.013
***********************************************************************
Webmin is a web-based interface that allows Unix-like operating
systems and common Unix services to be easily administered.

Installing Webmin in /usr/local/lib/webmin

Press Enter to configure /usr/local/webmin as the default data directory.
```
Config file directory [/usr/local/etc/webmin]:
```
Press Enter to configure /var/db/webmin as the default Webmin logs directory.
```
Log file directory [/var/db/webmin]:
```
Press Enter to configure /usr/local/bin/perl as the default Perl path.
```
Full path to perl (default /usr/local/bin/perl):
```

Press Enter to accept and use the default Webmin port 10000.

***********************************************************************
Operating system name:    FreeBSD
Operating system version: 14.1

***********************************************************************
Webmin uses its own password protected web server to provide access
to the administration programs. The setup script needs to know :
 - What port to run the web server on. There must not be another
   web server already using this port.
 - The login name required to access the web server.
 - The password required to access the web server.
 - If the web server should use SSL (if your system supports it).
 - Whether to start webmin at boot time.

Web server port (default 10000):

Press Enter to use admin as the default Webmin administrator username or enter your preferred username.
```
Login name (default admin): 
```
Assign and confirm a new login password for the admin user.
```
Login password: 
Password again: 
```

Enter y and press Enter to enable SSL on the Webmin web interface.

Use SSL (y/n):

                            console
                            
$ sudo service webmin enable

Output:

webmin enabled in /etc/rc.conf

Start the Webmin service.

                            console
                            
$ sudo service webmin start

Output:

Starting webmin.
Starting Webmin server in /usr/local/lib/webmin

Secure Virtualmin

Virtualmin listens for connection requests on port 10000 using self-signed SSL certificates depending on your Webmin configuration. Webmin uses the miniserv.pem certificate file in the /usr/local/lib/webmin by default. Follow the steps below to secure Virtualmin with trusted SSL certificates and set up new firewall rules to allow connections to Virtualmin web administration interface.

Search the available certbot version in the default pkg repository sources.

                            console
                            
$ sudo pkg search certbot

Output:

py311-certbot-2.11.0,1         Let's Encrypt client
py311-certbot-apache-2.11.0    Apache plugin for Certbot
py311-certbot-nginx-2.11.0     NGINX plugin for Certbot

py311-certbot is the latest Certbot package available for installation based on the above output.

Install the Certbot Let's Encrypt client tool.
console
```
$ sudo pkg install -y py311-certbot
```

Generate a new Let's Encrypt SSL certificate to use with Virtualmin. Replace virtualmin.example.com with your actual domain and hello@example.com with your email address.

                            console
                            
$ sudo certbot --standalone certonly -d virtualmin.example.com -m hello@example.com --agree-tos

Your output should be similar to the one below when successful.

Successfully received certificate.
Certificate is saved at: /usr/local/etc/letsencrypt/live/virtualmin.example.com/fullchain.pem
Key is saved at:         /usr/local/etc/letsencrypt/live/virtualmin.example.com/privkey.pem
This certificate expires on 2024-12-10.
These files will be updated when the certificate renews.

NEXT STEPS:
- The certificate will need to be renewed before it expires. Certbot can automatically renew the certificate in the background, but you may need to take steps to enable that functionality. See https://certbot.org/renewal-setup for instructions.
We were unable to subscribe you the EFF mailing list because your e-mail address appears to be invalid. You can try again later by visiting https://act.eff.org.

Merge the new Let's Encrypt SSL certificate and private key into a single file such as webmin_cert.pem.

                            console
                            
$ sudo  cat /usr/local/etc/letsencrypt/live/virtualmin.example.com/fullchain.pem /usr/local/etc/letsencrypt/live/virtualmin.example.com/privkey.pem > webmin_cert.pem

Move the webmin_cert.pem file to the /usr/local/lib/webmin directory.
console
```
$ sudo mv webmin_cert.pem /usr/local/lib/webmin
```
Open the main Webmin configuration file /usr/local/lib/webmin/miniserv.conf using a text editor such as vi.
console
```
$ sudo vi /usr/local/lib/webmin/miniserv.conf
```

Find the following keyfile directive.

                            ini
                            
keyfile=/usr/local/etc/webmin/miniserv.pem

Change the value to your webmin_cert.pem path.
ini
```
keyfile=/usr/local/etc/webmin/webmin_cert.pem
```
Save and close the file.
Enable the ipfw firewall service to automatically start at system boot.
console
```
$ sudo sysrc firewall_enable="YES"
```
Output:
```
firewall_enable: NO -> YES
```
Enable quiet mode to disable firewall messages in your standard output (STDOUT).
console
```
$ sudo sysrc firewall_quiet="YES"
```
Output:
```
firewall_quiet: NO -> YES
```

Change the firewall operation type to workstation.

                            console
                            
$ sudo sysrc firewall_type="workstation"

Output:

firewall_type: UNKNOWN -> workstation

Allow SSH, HTTPS, and Virtualmin port 10000 connections through the firewall.

                            console
                            
$ sudo sysrc firewall_myservices="ssh/tcp http/tcp https/tcp 10000/tcp"

Output:

firewall_myservices: ssh/tcp http/tcp https/tcp -> ssh/tcp http/tcp https/tcp 10000/tcp

Enable network connections from any host to your server.

                            console
                            
$ sudo sysrc firewall_allowservices="any"

Output:

firewall_allowservices:  -> any

Log all blocked network connections to /var/log/security.
console
```
$ sudo sysrc firewall_logdeny="YES"
```
