Installing Webmin/Virtualmin on Ubuntu 18.04

Webmin/Virtualmin is a web-based control panel for managing Unix-like systems. It allows administrators to simplify the process of managing multiple domains, mailboxes, databases, and websites on a single server.

To install Webmin/Virtualmin on Ubuntu 18.04, follow the steps below:

Step 1: Update System Packages

Before installing any software, it is recommended to update the system packages to their latest versions. Open a terminal and run the following commands:

sudo apt update

sudo apt upgrade

Step 2: Install Webmin

To install Webmin, you need to add its repository to the system. Run the following commands:

sudo nano /etc/apt/sources.list

Add the following line at the end of the file:

deb https://download.webmin.com/download/repository sarge contrib

Press CTRL + X to save and exit the file.

Next, add the GPG key of the repository:

wget http://www.webmin.com/jcameron-key.asc

sudo apt-key add jcameron-key.asc

Update the system packages again:

sudo apt update

Now, install Webmin:

sudo apt install webmin

During the installation, you will be prompted to configure the usage of SSL on Webmin. Choose "no" if you do not have an SSL certificate, or "yes" if you have a valid certificate.

Step 3: Access Webmin

By default, Webmin is configured to listen on port 10000. Open a web browser and enter the following URL:

https://your_server_ip:10000/

Replace "your_server_ip" with the actual IP address of your server.

Accept the self-signed SSL certificate warning (if applicable) and enter your system's root username and password to log in.

Step 4: Install Virtualmin (Optional)

If you want to install Virtualmin, a powerful web hosting control panel built on top of Webmin, you can do so by following these steps:

Run the following command to install Virtualmin's dependencies:

sudo apt install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python

Next, download and run the Virtualmin installation script:

wget http://software.virtualmin.com/gpl/scripts/install.sh

sudo chmod +x install.sh

sudo ./install.sh

The installation script will guide you through the process of installing and configuring Virtualmin. Make sure to follow the instructions on the screen.

Once the installation is complete, you can access Virtualmin by visiting the following URL:

https://your_server_ip:10000/

Replace "your_server_ip" with the actual IP address of your server.

Congratulations! You have successfully installed Webmin/Virtualmin on Ubuntu 18.04. You can now start managing your server and hosting multiple websites with ease.
