  3. While updating multiple packages, they are complete in a single YUM or APT method if possible.
  4. Clone Unix users and groups with single button.

This brief tutorial will explain you how to install latest Webmin in Linux systems. I assume that the following installation guidelines will work on all major Linux flavours like RHELCentOSFedora and DebianUbuntuLinux Mint.

Installing Webmin Control Panel in Linux

We are using Webmin repository for installing latest Webmin tool with their required dependencies and we also receive up-to-date automatic updates of Webmin via repository.

On RHEL/CentOS/Fedora

As I said, if we like to receive future updates we need to add and enable Webmin repository, do to this create a file called /etc/yum.repos.d/webmin.repo and add the following lines to it as a root user.

# vi /etc/yum.repos.d/webmin.repo
name=Webmin Distribution Neutral
Install Webmin Yum Repository

On Debian/Ubuntu/Linux Mint

Open “/etc/apt/sources.list” file on your system with nano editor.

$ sudo nano /etc/apt/sources.list

Add the following lines at the bottom of the file. Save and close it.

deb http://download.webmin.com/download/repository sarge contrib
deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib
Add Webmin APT Repository

Next, import and install GPG Key for installing signed packages for Webmin. We use Wget command to fetch the key and then add it to the system.

------------------- [on Red Hat based systems] ------------------- 

# wget http://www.webmin.com/jcameron-key.asc
# rpm --import jcameron-key.asc       
Import Webmin Key: Red Hat systems
------------------- [on Debian based systems] ------------------- 

$ wget http://www.webmin.com/jcameron-key.asc
$ sudo apt-key add jcameron-key.asc   
Add Webmin Key: On Debian systems

Once we have all the above required configuration, now we can able to install it using yum or apt-get command. It will automatically install all required dependencies.

------------------- [on Red Hat based systems] -------------------

# yum update
# yum install webmin    
Install Webmin on RedHat Systems
------------------- [on Debian based systems] -------------------

$ sudo apt-get update
$ sudo apt-get install webmin
Install Webmin in Debian and Ubuntu

Starting Webmin

Run the following commands to star the service.

------------------- [on RedHat based systems] -------------------
# /etc/init.d/webmin start
# /etc/init.d/webmin status
Start Webmin on RedHat Systems
------------------- [on Debian based systems] -------------------

$ sudo /etc/init.d/webmin start
$ sudo /etc/init.d/webmin status
Start Webmin on Debian Systems

Step 3: Accessing Webmin

By default Webmin runs on port 10000, so we need to open port on our firewall to access it. The easiest way to open the port on firewall is using iptables rules.

Once we’ve added the rule, we will need to restart the firewall to apply new configuration. This can be achieved by running the command.

------------------- [On RHEL/CentOS 6.x/5.x and Fedora 18-12] -------------------

# iptables -A INPUT -p tcp -m tcp --dport 10000 -j ACCEPT
# service iptables save
# /etc/init.d/iptables restart
------------------- [On RHEL/CentOS 7.x and Fedora 19 Onwards] -------------------

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

Now we should able to access and login to Webmin using URL http://localhost:10000/ and enter the username as root and password (current root password), for remote access just replace localhost with your remote IP address.
