Install Webmin on CentOS 8

Webmin is an open-source control panel that allows you to manage your Linux server through an easy-to-use web interface. It allows you to manage users, groups, disk quotas, create files and directories as well as configure most popular services including web, FTP, email and database servers.

This tutorial explains how to install Webmin on CentOS 8.


To be able to install packages, you need to be logged in as root or user with sudo privileges .

Installing Webmin on CentOS

The recommended method for installing Webmin on CentOS 8 is to enable the Webmin repository and install the Webmin package using the dnf package manager.

Perform the following steps to install Webmin on CentOS:

  1. Open your favorite text editor and create the repository file:

    sudo nano /etc/yum.repos.d/webmin.repo

    Paste the following content into the file:

    name=Webmin Distribution Neutral

    Save the file and close the editor.

  2. Import the Webmin GPG key using the following rpm command:

    sudo rpm --import
  3. Install the latest version of Webmin by typing:

    sudo dnf install webmin

    The command automatically resolves all dependencies. Once the installation finishes, the following output is displayed:

    Webmin install complete. You can now login to https://your_server_ip_or_hostname:10000/
    as root with your root password.

    The Webmin service will start automatically.

That’s it! At this point, you have successfully installed Webmin on your CentOS 8 server.

Adjust the Firewall

By default, Webmin listens for connections on port 10000 on all network interfaces.

To be able to access the Webmin interface from a web browser, you need to open the Webmin port in your server’s firewall .

Run the following commands to allow traffic on port 10000:

sudo firewall-cmd --zone=public --add-port=10000/tcpsudo firewall-cmd --runtime-to-permanent

Accessing Webmin Web Interface

Now that Webmin is installed on your CentOS server open your [favorite browser and type your server’s hostname name or public IP address followed by the Webmin port 10000:


The browser will complain about the certificate being not valid, because by default, Webmin uses an untrusted self-signed SSL certificate .

Login to the Webmin web interface using your root user credentials:
