This step is entirely optional and only applies to those looking to run multiple websites from a single server. Up to now, our LAMP configuration supports just one site. To host more than one website, you must create or adjust virtual host files. Apache virtual hosts allow you to manage configurations for multiple domains within one server.

In this section, we will walk through the setup of an Apache virtual host file specifically for Rocky Linux, which will show you how to configure your own virtual hosts.

Prerequisites

• You should have a Fully Qualified Domain Name (FQDN) directed to your server’s public IP address via your DNS provider.
• A running instance of Rocky Linux 8 with the LAMP stack already installed.

Note: In our example, we are using tecmint.info as the domain name, which points to our server's public IP. Replace it with your actual domain wherever it appears in the instructions.

Setting Up the Apache Virtual Directory Structure

The first task is to build a directory that will store the website content. This directory will act as the DocumentRoot, located under the /var/www/ path. Run the following command:

<code>$ sudo mkdir -p /var/www/tecmint.info/html</code>

Now, create a basic index.html file to test the virtual host configuration.

<code>$ sudo vim /var/www/tecmint.info/html/index.html</code>

Add the following HTML code inside the file:

<code>


    <title>Welcome to tecmint.info!</title>
<h1>Success! The tecmint.info virtual host is working properly!</h1>

</code>

Once done, save and exit the file.

Next, assign ownership of the webroot directory to your current user to avoid permission issues when editing files.

<code>$ sudo chown -R $USER:$USER /var/www/tecmint.info/html</code>

Configuring an Apache Virtual Host File

We'll now create a dedicated virtual host file for our domain. On Rocky Linux 8, similar to CentOS 8, Apache loads its configurations from the /etc/httpd/conf.d directory.

Create a new virtual host file using the following command:

<code>$ sudo vim /etc/httpd/conf.d/tecmint.info.conf</code>

Insert the configuration below into the file:

<code><virtualhost>
    ServerName <strong>www.tecmint.info</strong>
    ServerAlias <strong>tecmint.info</strong>
    DocumentRoot /var/www/<strong>tecmint.info</strong>/html

    <directory>tecmint.info/html>
        Options -Indexes  FollowSymLinks
        AllowOverride All
    </directory>

    ErrorLog /var/log/httpd/<strong>tecmint.info</strong>-error.log
    CustomLog /var/log/httpd/<strong>tecmint.info</strong>-access.log combined
</virtualhost></code>

Save the changes and close the file.

Before applying the configuration, verify that there are no syntax errors by running:

<code>$ sudo apachectl configtest</code>

If the configuration is correct, restart Apache to apply the changes:

<code>$ sudo systemctl restart httpd</code>

Now open your browser and visit your domain:

<code>http://tecmint.info</code>

You should see the test HTML page we created earlier. This confirms that the virtual host has been set up correctly.

Repeat these steps for each additional domain you wish to host on the same server.

Summary

That concludes the process. We've successfully configured virtual host files to support hosting multiple websites or domains on Rocky Linux 8 using the LAMP stack. You're now ready to deploy your applications or secure your Apache server with an SSL certificate via Let’s Encrypt.
