In this guide, we’ll walk you through how to install Webmin on RHEL 9 or CentOS 9, ensuring smooth server management with ease.
Managing a server efficiently often requires robust administrative tools that streamline tasks and provide a user-friendly interface. Webmin is one such tool, offering a comprehensive web-based administration platform for Linux servers.
Webmin, initially released in 1997 by Jamie Cameron, quickly gained popularity as a powerful web-based system administration tool for Unix-like systems.
Over the years, Webmin has evolved into a feature-rich platform, offering administrators a graphical interface to manage various aspects of their servers, including user accounts, file systems, network configurations, and more. Its modular design allows for easy extension with additional modules, catering to a wide range of server management needs.
Despite its longevity, Webmin continues to receive regular updates and improvements, ensuring compatibility with modern Linux distributions and addressing security vulnerabilities. Its active community of developers and users contributes to its ongoing development and maintenance, making it a reliable choice for server administration tasks.
For illustrative purposes, we’ve configured our system with the following settings (set yours according to your environment):
| Hostname | testsrv1.localdomain |
| Public IP address | 192.168.1.240 (Private IP: 10.0.2.15) |
| RAM | 2 |
| Cores | 2 |
Now, let’s dive into the installation process of Webmin on your RHEL 9 or CentOS 9 server.
Before proceeding with the installation of Webmin, it’s essential to ensure that your system is up-to-date. Open a terminal and run the following commands:
$ sudo dnf update -y
This will update your system with the latest packages and security patches, ensuring a stable environment for Webmin installation.
Webmin relies on several dependencies to function correctly. Install them by executing the following command:
$ sudo dnf install perl perl-CPAN perl-App-cpanminus perl-Digest-SHA perl-Net-SSLeay perl-Data-Dumper
Next, download the latest version of Webmin from the official website or repository. You can use wget or curl to download the package (most recent version as of the date of this publication) directly to your system. For example:
$ wget https://github.com/webmin/webmin/releases/download/2.105/webmin-2.105-1.noarch.rpm
Once the package is downloaded, install it using the dnf package manager:
$ sudo dnf install ./webmin-2.105-1.noarch.rpm
This command will install Webmin along with its dependencies on your system.

After the installation is complete, start the Webmin service using the following command:
$ sudo systemctl start webmin
You can also enable the service to start automatically on system boot:
$ sudo systemctl enable webmin
Now lets open the Webmin port (10000) for access by running the following commands:
$ sudo firewall-cmd --permanent --add-port=10000/tcp
$ sudo firewall-cmd --reload
Webmin should now be up and running on your server. Open a web browser and navigate to the following address:
