Installation of Webmin on CentOS 8

The process of installing Webmin on CentOS 8 is quite straightforward. You can install Webmin on CentOS 8 machine using the RPM package in only four simple steps.

Step 1: Update CentOS8 System

First, update the DNF package repository cache and make sure that the system is up-to-date. To update the DNF repository cache, issue the following command.

$ sudo dnf makecache

$ sudo dnf upgrade

Now, after updating the DNF repository cache and installed packages, we will download the Webmin RPM package and then install it using the dnf package manager.

Step 2: Download Webmin RPM Package

To download the RPM package of Webmin, you can either:

Download the RPM file from the official website of Webmin by visiting the link below:

Or, download the RPM package of Webmin by issuing the following command in the CentOS 8 terminal.

$ wget http://prdownloads.sourceforge.net/webadmin/webmin-1.970-1.noarch.rpm

After downloading the Webmin RPM package, download and install the optional dependencies by entering the command given below.

Now, the latest stable version of Webmin has been installed.

You can start using the Webmin Control panel by going to a browser and visiting the localhost with the port 10000 since the default port of Webmin is 10000.

https://localhost:10000

To connect to the Webmin remotely, you will need to configure the Firewall settings for Webmin.

Since Webmin listens on port 10000 by default, we will need to add port 10000 to the firewall. To allow port 10000, enter the following command:

$ sudo firewall-cmd --add-port=10000/tcp --zone=public --permanent

Once the firewall has been configured, you should now be able to access the web interface remotely.
