4. Command to install Webmin on AlmaLinux 8

Finally, everything we need is at its place. Let’s now run a single command to download and install Webmin on our RPM-based Almalinux Linux operating system.

dnf install webmin

 

5. Allow Webmin Port number in Firewall

To access the web interface of this web-based system configuration tool from any system browser that can access the Server’s IP address or domain where we have installed it; we have to open a Webmin port number that is 10000 in the Firewall.

firewall-cmd --add-port=10000/tcp --permanent
firewall-cmd --reload

 

6. Access Webmin Web Interface

Webmin can be accessed via any web browser from a computer that has access to the system to be administered via the network. In addition to the computer name, the port on which Webmin is running (10000) must be specified. For example, if the Webmin installed on Almalinux needs to be administered via browser, its Ip-address or domain in the URL box must be specified along with 10000 port. If you use Webmin on a system with a graphical user interface, administration can of course be done using the local address in the URL i.e http://localhost: 10000. If only encrypted communication is possible on the system, replace http with https.

Example:

https://server-ip-address:10000
or
https://example.com:10000

If you don’t have implemented SSL, then you will get a warning  “Your connection is not private”. Click on the Advanced button and click on the Proceed to x.x.x.x (unsafe) link.
