Prerequisites to Setup Apache Virtual Host on Ubuntu 22.04
Before setting up Apache Virtual Hosts on Ubuntu 22.04, ensure you have the following prerequisites in place:
- Ubuntu 22.04 is installed and running on your server.
- Apache web server installed.
The apache2 generally comes pre-installed on Ubuntu and you can check its version by executing the below command:
$ apache2 -v
If for any reason it’s not installed then you can install it using the following command:
$ sudo apt install apache2
Next, you can check the status of apache2 web server if it’s up and running by executing:
$ systemctl status apache2
You can see in the above image that the apache2 web server is currently active.
Another method to verify this is by opening your desired web browser on Ubuntu and typing “localhost”:
When you visit “localhost” in your browser, the Apache2 server responds to your request by serving up its default web page. So, seeing Apache2 means that the server is up and running correctly, and ready to serve web pages.
How to Set up Apache Virtual Host on Ubuntu 22.04
When you’re setting up a web server using Apache2, you’ll often want to put your website files in a location where the server can access them. By navigating to “/var/www”, you’re positioning yourself within the directory where Apache2 expects to find web content. This means that when you add or create web files here, Apache2 can serve them to visitors who access your website through their web browsers.

Step 1: Creating a directory structure
Execute the following command to navigate there:
cd /var/www
You need to create a directory for each website you want to host. For example:
sudo mkdir -p /var/www/example.com/
The purpose of this command is to create a directory named “example.com” inside the “/var/www” directory on the file system. The “-p” option ensures that if the “/var/www” directory doesn’t exist, it and any intermediate directories needed to reach it will be created.
By creating the directory “/var/www/example.com/”, you’re preparing a location to store files specific to that domain within the web server’s file system.
Step 2: Changing Ownership
Next, you need to change the ownership of the directory “/var/www/example.com” and all its contents to the user and group “www-data.” By doing so, you are ensuring that the Apache2 web server process running on your system has the necessary permissions to access and serve the files within this directory.
sudo chown -R www-data:www-data /var/www/example.com
Step 3: Creating a Web Page
After that, you need to set up the HTML home page for your apache2 web server which is “index.html” in this case.
sudo nano /var/www/example.com/index.html
The nano text editor has been used for this purpose and then we need to write the following HTML code inside this file:
<html> <head> <title>Welcome</title> </head> <body> <h1> This guide is about setting up apache2 web server</h1> </body> </html>
Step 4: Creating an Apache Virtual Host file
When setting up a website on an Apache2 web server, it’s essential to configure Apache2 to serve the website correctly. This includes defining how Apache2 should handle requests for specific domains, such as “example.com” in this case:
$ sudo nano /etc/apache2/sites-available/example.com.conf
<VirtualHost *:80> ServerAdmin [email protected] ServerName example.com ServerAlias www.example.com DocumentRoot /var/www/example.com ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost>
The configuration file specified by this command allows you to define settings such as the document root directory, server name, virtual hosts, and other directives related to how Apache2 should serve the website.
Step 5: Configure the Main Apache2 File
Next, you need to open the Apache configuration file with superuser privileges, allowing you to view and modify the global settings for your Apache web server:
sudo nano /etc/apache2/apache2.conf
After opening this file add the following line and exit the file after saving it:
ServerName example.com
Adding ServerName example.com ensures that Apache accurately identifies itself and handles requests appropriately. Here, you need to provide your desired name in place of example.com.
Step 6: Enabling Virtual Host Configuration
Now, you need to enable a virtual host configuration file that allows Apache to serve content for the associated domain or website. Once enabled, Apache will read the configuration settings from this file during server startup or reload:
sudo a2ensite example.com.conf
Step 7: Disabling Default Virtual Host Configuration
You also need to disable the default virtual host configuration to stop the Apache from serving content for the associated domain or website:
sudo a2dissite 000-default.conf
After disabling a virtual host configuration file, you usually need to reload Apache for the changes to take effect:
sudo systemctl reload apache2
Step 8: Error testing
Lastly, if you need to verify that all the configurations that you made are correct and there is no error that can occur then you can do that by executing:
sudo apache2ctl configtest
Running this command after modifying your Apache configuration files is recommended to guarantee the continued smooth operation of your web server.
You can see that there is no error showing in the output which means that the Apache virtual host has been set up successfully on Ubuntu 22.04.
