Step-by-Step Tutorial to Create Webmin on Linux Server

Managing Linux servers using the command line can be challenging, especially for beginners or administrators managing multiple systems. Webmin is a web-based interface that allows system administrators to create Webmin setup and manage Linux servers easily through a browser, without needing deep command-line knowledge. It provides tools for user management, service configuration, and system monitoring.

In this article, we’ll cover how to create Webmin on a Linux server. You’ll learn prerequisites, installation steps, configuration, managing services, troubleshooting common issues, and best practices. By the end, you’ll be able to manage your Linux server efficiently through Webmin’s graphical interface.

Prerequisites

Before installing Webmin, make sure your system meets these requirements:

• A Linux server (Ubuntu, Debian, CentOS, RHEL) with root or sudo access.
• Internet connection to download Webmin packages.
• Firewall configured to allow Webmin port (default 10000).
• Basic understanding of Linux server administration.

Meeting these prerequisites ensures a smooth installation and access to the Webmin interface.

What is Webmin and Why Use It?

Webmin is a powerful, web-based system administration tool designed for Unix-like systems, including Linux. Instead of relying solely on complex command-line operations, Webmin provides a graphical dashboard that makes server management more intuitive. Through its browser-based interface, administrators can easily configure and monitor different aspects of a server, including:

• User accounts and groups – Create, modify, or remove users and set permissions.
• Web servers – Manage services like Apache, Nginx, and LiteSpeed without editing configuration files manually.
• Database servers – Control MySQL, MariaDB, or PostgreSQL directly from the dashboard.
• Networking services – Configure DNS, FTP, and mail servers.
• System administration – Review logs, schedule cron jobs, set disk quotas, and manage system updates.

By offering these tools in a centralized interface, Webmin simplifies Linux administration for beginners while still offering advanced features for experienced system administrators. It reduces the need for repetitive terminal commands, speeds up server management, and helps avoid configuration errors.

Installing Webmin on Linux

Installing Webmin on Linux is simple, as it’s available through official repositories and package downloads. With just a few commands, you can set up Webmin and start managing your server through a web-based interface.

Step 1: Update System Packages

sudo apt update && sudo apt upgrade -y    # Ubuntu/Debian
sudo yum update -y                        # CentOS/RHEL

Step 2: Install Required Dependencies

• Ubuntu/Debian:

sudo apt install wget apt-transport-https software-properties-common -y

• CentOS/RHEL:

sudo yum install wget perl -y

Step 3: Add Webmin Repository

• Ubuntu/Debian:

wget -q -O- http://www.webmin.com/jcameron-key.asc | sudo apt-key add -
sudo add-apt-repository "deb http://download.webmin.com/download/repository sarge contrib"
sudo apt update
sudo apt install webmin -y

• CentOS/RHEL:

wget http://www.webmin.com/download/rpm/webmin-current.rpm
sudo rpm -Uvh webmin-current.rpm

Step 4: Verify Installation

Webmin runs on port 10000 by default. Access it via:

https://your-server-ip:10000

Log in using root or sudo credentials.

Configuring Webmin on Linux

After installation, configuring Webmin is essential to ensure secure and efficient server management. Basic steps include setting up user access, enabling SSL for secure connections, and customizing modules to match your server requirements.

Step 1: Adjust Firewall

Allow access to Webmin port (10000):

sudo ufw allow 10000/tcp    # Ubuntu/Debian
sudo firewall-cmd --permanent --add-port=10000/tcp   # CentOS/RHEL
sudo firewall-cmd --reload

Step 2: Configure SSL

Webmin uses HTTPS by default. You can configure SSL certificates via the Webmin interface or use Let’s Encrypt for trusted certificates.

Step 3: Manage Users

Webmin allows creating admin or limited-access users for system management:

• Go to Webmin → Webmin Users
• Add users and assign module access permissions

This ensures controlled access while maintaining security.

Managing Services via Webmin

Webmin provides a centralized interface to manage various services:

• Apache/Nginx: Start, stop, configure virtual hosts.
• MySQL/MariaDB: Manage databases, users, and permissions.
• DNS (BIND): Configure zones, records, and queries.
• FTP/SSH: Control access, accounts, and permissions.

Webmin also supports cron jobs, package management, disk quotas, and log monitoring, reducing the need for command-line interventions.

Troubleshooting Common Webmin Issues

Even though Webmin is reliable, issues may occasionally arise during use. Understanding common problems and their fixes helps ensure smooth server management and uninterrupted access. Below are some frequent issues and solutions:

• Cannot access Webmin → Check firewall rules and ensure port 10000 is open.
• SSL certificate issues → Reconfigure SSL settings via Webmin or install a Let’s Encrypt certificate.
• Login problems → Verify username/password or reset the admin password: sudo /usr/share/webmin/changepass.pl /etc/webmin root newpassword
• Service not starting → Check Webmin logs for errors: sudo tail -f /var/webmin/miniserv.log

By proactively monitoring these areas, you can quickly fix Webmin issues and maintain a secure, reliable management interface.

FAQs: Create Webmin on Linux Server
