What Is Web Server in Debian Install?


Angela Bailey

A web server is a software application that serves content to be accessed over the internet. In Debian, installing a web server involves a few steps to get your website up and running. In this tutorial, we will explore how to install a web server in Debian and some important configuration options.

Step 1: Update and Upgrade

Before installing any new software, it’s always a good idea to update and upgrade your system. This ensures that you have the latest security patches and bug fixes.

To update your Debian system, open the terminal and run the following command:

sudo apt update

Once the update is complete, you can upgrade your system using the following command:

sudo apt upgrade

Step 2: Installing Apache

The most popular web server in Debian is Apache. It is widely used due to its stability, performance, and rich feature set.

To install Apache, use the following command:

sudo apt install apache2

Starting Apache

After installation, Apache should start automatically. To ensure it’s running, use the following command:

sudo systemctl status apache2

If you see “Active: active (running)” in the output, it means Apache is up and running.

Step 3: Testing Apache Installation

To test if Apache is working correctly, open a web browser on your local machine and enter http://localhost/. You should see an “Apache2 Debian Default Page” indicating a successful installation.

Document Root

The default document root for websites in Debian is /var/www/html/. Any files placed in this directory will be served by Apache.

Step 4: Firewall Configuration

By default, Debian comes with a firewall called UFW (Uncomplicated Firewall). If you have UFW enabled, you need to allow incoming HTTP and HTTPS traffic to access your web server.

To allow incoming HTTP traffic, run the following command:

sudo ufw allow 'Apache'

To allow incoming HTTPS traffic, run the following command:

sudo ufw allow 'Apache Full'

Step 5: Virtual Hosts

If you plan to host multiple websites on your Debian web server, you can set up virtual hosts. Virtual hosts allow you to serve different websites from a single server.

To create a virtual host configuration file, navigate to the /etc/apache2/sites-available/ directory and create a new file with a .conf extension. For example:

sudo nano /etc/apache2/sites-available/example.com.conf

In this file, you need to specify the website’s domain name and document root. Here’s an example configuration:

<VirtualHost *:80>
    ServerName example.com
    DocumentRoot /var/www/example.com/public_html

Save the file and exit the text editor.

Next, enable the virtual host by creating a symbolic link in the /etc/apache2/sites-enabled/ directory. Use the following command:

sudo ln -s /etc/apache2/sites-available/example.conf /etc/apache2/sites-enabled/

Restarting Apache

After making any changes to the Apache configuration, you need to restart the server for the changes to take effect. Use the following command:

sudo systemctl restart apache2

Your virtual host is now ready, and you can upload your website files to the specified document root.


Installing a web server in Debian is a straightforward process. By following these steps, you can have Apache up and running, serving your websites in no time. Remember to keep your system updated and secure by regularly applying updates and configuring firewalls.

Now that you have a good understanding of how to install a web server in Debian, you can start hosting your websites or exploring more advanced configuration options.
