In a computer network, it is necessary to know what is happening on the server. Therefore, today I will teach you how to install Webmin on Debian 9.
Webmin is a web-based interface for managing UNIX systems. It has a new web interface where you can modify and manage several things on the computer. For example, user accounts, UNIX groups, DNS and others.
You will have no license problems with Webmin because it is released under the GPL3 license, which guarantees that you can use it, modify it and install it as you want.
Let’s install Webmin on Debian 9.
1. Upgrade the system
The first step in this installation is to update the system packages. This ensures that your system has the latest security patches and thereby improves the stability and robustness of the system.
:~$ su :~# apt update && apt upgrade
As I said before, getting the latest security patches and keeping the system up to date is essential for the security of your computer.
2. Add the Webmin repository and install Webmin
A simple way to install Webmin is through its package repository. Then, first of all, you need to add it to later install Webmin from APT.
Edit the apt source file:
:~# nano /etc/apt/sources.list
And add the following:
deb https://download.webmin.com/download/repository sarge contrib
Press Ctrl + X and say yes to save the file.
Next, it is necessary to add the GPG key to the repository. This is for security reasons. First, download it.
:~# wget http://www.webmin.com/jcameron-key.asc
Then, add it.
:~# apt-key add jcameron-key.asc
Next, it is necessary to install some additional packages.
:~# apt install apt-transport-https
Finally, install Webmin.
:~# apt update :~# apt install webmin
Once the installation is finished, you will be told the address from where you must access through the web browser. In addition, the installer will tell you to log in with a user who can use sudo.
3. Using Webmin
Before using Webmin, it is necessary to define some rules in the Firewall.
:~# ufw allow 443/tcp :~# ufw allow 10000/tcp
Now, open your web browser and open the application. Remember that the address to open the application from the web browser is indicated at the end of the installation. Keep that in mind.
And you will see this:
On the left side, you have all the options available to manage the server. For example, try viewing the web server options.
Conclusion
Webmin is a robust application to manage servers in a computer network. We can also use it to monitor them effectively.
