Virtualmin is a powerful and free web hosting control panel for Linux servers that offers a complete alternative to commercial solutions like cPanel and Plesk. Built on the renowned Webmin framework, Virtualmin combines extensive functionality with the freedom of open-source software, making it an attractive choice for both individual webmasters and hosting companies.

The history of Virtualmin

Virtualmin was founded in 2005 by Jamie Cameron, the same developer who created Webmin. Webmin, which has existed since 1997, is one of the most widely used web-based system administration tools for Unix systems. Virtualmin was developed as a module on top of Webmin specifically focused on web hosting tasks.

The project started as an open-source initiative and grew into a mature platform with both a free GPL version and a commercial Pro version with extra features. Today, Virtualmin is used by an estimated hundreds of thousands of servers worldwide, from small personal servers to large hosting infrastructures. It remains one of the most popular free alternatives to cPanel.

What is Virtualmin and what is it used for

Virtualmin is a hosting control panel that provides all the tools you need to manage websites, email, databases, and DNS on a Linux server. It distinguishes itself through deep integration with the underlying operating system and the extensive configuration options it offers.

Unlike cPanel or Plesk, which offer a more polished but also more limited interface, Virtualmin gives you access to virtually all aspects of your server. This makes it ideal for system administrators who want complete control without command-line work, but can be overwhelming for beginning users.

Top 5 features of Virtualmin

  1. Completely free GPL version - Complete hosting functionality without license costs
  2. Deep Linux integration - Direct management of all system and server configurations
  3. Resource limits - Detailed control over CPU, memory, disk space, and processes per account
  4. Installer scripts - One-click installation of WordPress, Drupal, Joomla, and 100+ other applications
  5. Multi-server support - Manage multiple servers from one interface

The main features of Virtualmin

Website management

Virtualmin offers extensive capabilities for managing websites. You can create and configure virtual hosts for Apache or Nginx, install SSL certificates (including automatic Let's Encrypt integration), and manage directory structures. Each website can have its own PHP version with customized settings.

The system supports both traditional websites and modern applications. You can easily host Node.js, Python, or Ruby applications alongside classic PHP sites. Subdomains, aliases, and redirects are fully supported.

Email server management

Virtualmin integrates with Postfix and Dovecot for complete email functionality. You can create mailboxes, configure aliases, set up autoresponders, and manage mailing lists. Spam filtering via SpamAssassin and virus scanning via ClamAV are supported by default.

The webmail interface (Roundcube or Usermin) gives users access to their email via the browser. Advanced features like DKIM signing, SPF configuration, and DMARC policies are available for better email deliverability.

Database management

MySQL/MariaDB and PostgreSQL are fully supported with graphical management tools. You can create databases, manage users, make backups, and execute SQL queries from the interface. phpMyAdmin and phpPgAdmin are available for detailed database management.

Each virtual server gets its own database user with limited rights, which increases security. Automatic database backups can be configured as part of the general backup scheme.

DNS server

Virtualmin can function as a full DNS server with BIND or Webmin's own DNS module. DNS zones are automatically created for new websites and can be manually adjusted. DNSSEC is supported for improved DNS security.

For hosting companies, the ability to function as secondary DNS is valuable. You can also set up DNS clustering where changes are automatically synchronized to slave servers.

Script installers

The Install Scripts system enables one-click installation of popular applications. WordPress, Drupal, Joomla, Magento, PrestaShop, and over 100 other scripts can be automatically installed and configured. Updates are tracked and can often also be automated.

Backup and restore

Virtualmin has extensive backup capabilities. You can back up complete virtual servers including files, databases, email, and configuration. Backups can be stored locally or to external locations like Amazon S3, Google Cloud Storage, or FTP servers.

Restore is as simple as making a backup. You can restore a complete server or selectively restore only certain parts. This makes disaster recovery easy and reliable.

Where Virtualmin really excels

Cost-effectiveness

The GPL version of Virtualmin is completely free and offers functionality comparable to paid alternatives. For hosting companies looking to avoid cPanel license costs, Virtualmin offers a solid alternative that can save thousands of euros per year.

Flexibility and control

Virtualmin gives you unprecedented control over your server. Virtually every setting is adjustable via the interface, and for cases where the interface isn't sufficient, you can fall back on underlying Webmin functionality. This makes Virtualmin ideal for experienced administrators.

Stability and reliability

With over 15 years of development, Virtualmin is a mature and stable platform. It's actively maintained and security updates are released quickly. The community is large and helpful.

Resource efficiency

Virtualmin is more efficient in resource usage than some commercial alternatives. This means you can host more websites on the same hardware, further lowering the total cost of ownership.

The downsides of Virtualmin

Learning curve

The extensive functionality also means a steeper learning curve. The interface is functional but not as polished as cPanel or Plesk. New users may need time to find their way around.

Less polished user experience

The customer portal for end users (Usermin) is functional but lacks the modern look-and-feel of competitors. This can be a disadvantage for hosting companies wanting to offer a premium appearance.

Limited integrations

The ecosystem of third-party integrations is smaller than cPanel. For specific features like billing integration, you're dependent on a more limited selection of tools.

Smaller support community

While the community is active, it's smaller than cPanel's. For specific problems, it may take longer to find answers.

The 5 most common problems with Virtualmin

1. DNS propagation

New domains may need time to propagate. Ensure your DNS servers are correctly configured and check propagation with tools like dnschecker.org.

2. Email deliverability

Ensure correct SPF, DKIM, and DMARC configuration. Check if your server IP is not on blacklists and configure reverse DNS correctly.

3. SSL certificate problems

Let's Encrypt renewals can fail with DNS or firewall problems. Check automatic renewal logs and ensure port 80 is reachable for challenges.

4. PHP configuration conflicts

Different sites may need different PHP versions or settings. Use PHP-FPM with separate pools per virtual server for maximum flexibility.

5. Disk quota issues

Quota problems occur if the quota system isn't correctly installed. Check if quota support is enabled in the kernel and filesystem.

When to choose Virtualmin

Virtualmin is the ideal choice for technically proficient users and companies wanting maximum control at minimal cost. It's excellently suited for developers, system administrators, and hosting companies that want to leverage Linux flexibility without the costs of commercial control panels.

For users who expect a polished, user-friendly experience or who depend on specific cPanel integrations, Plesk or even cPanel may be a better choice despite higher costs. But for those willing to invest in the learning curve, Virtualmin offers unparalleled value.
