How To Set Up Apache Virtual Hosts on Ubuntu 18.04 ...

Introduction

This tutorial will guide you through setting up multiple domains and websites using Apache virtual hosts on an Ubuntu 18.04 server. During this process, you’ll learn how to serve different content to different visitors depending on which domains they are requesting.

For a more detailed version of this tutorial, with more explanations of each step, please refer to How To Set Up Apache Virtual Hosts on Ubuntu 18.04.

Prerequisites

In order to complete this tutorial, you will need access to the following on an Ubuntu 18.04 server:

A sudo user on your serverAn Apache2 web server, which you can install with sudo apt install apache2

Step 1 — Create the Directory Structure

We’ll first make a directory structure that will hold the site data that we will be serving to visitors in our top-level Apache directory. We’ll be using example domain names, highlighted below. You should replace these with your actual domain names.

sudo mkdir -p /var/www/example.com/public_htmlsudo mkdir -p /var/www/test.com/public_html

Step 2 — Grant Permissions

We should now change the permissions to our current non-root user to be able to modify the files.

sudo chown -R $USER:$USER /var/www/example.com/public_htmlsudo chown -R $USER:$USER /var/www/test.com/public_html

Additionally, we’ll ensure that read access is permitted to the general web directory and all of the files and folders it contains so that pages can be served correctly.

sudo chmod -R 755 /var/www

Step 3 — Create Demo Pages for Each Virtual Host

Let’s create some content to serve, we’ll make a demonstration index.html page for each site. We can open up an index.html file in a text editor for our first site, using nano for example.

nano /var/www/example.com/public_html/index.html

Within this file, create a domain-specific HTML document, like the following:

/var/www/example.com/public_html/index.html

Welcome to Example.com!

Success! The example.com virtual host is working!

Save and close the file, then copy this file to use as the basis for our second site:

cp /var/www/example.com/public_html/index.html /var/www/test.com/public_html/index.html

Open the file and modify the relevant pieces of information:

nano /var/www/test.com/public_html/index.html

/var/www/test.com/public_html/index.html

Welcome to Test.com!

Success! The test.com virtual host is working!

Save and close this file as well.

Step 4 — Create New Virtual Host Files

Apache comes with a default virtual host file called 000-default.conf that we’ll use as a template. We’ll copy it over to create a virtual host file for each of our domains.

Create the First Virtual Host File

Start by copying the file for the first domain:

sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/example.com.conf

Open the new file in your editor (we’re using nano below) with root privileges:

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

We will customize this file for our own domain. Modify the highlighted text below for your own circumstances.

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

ServerAdmin admin@example.comServerName example.comServerAlias www.example.comDocumentRoot /var/www/example.com/public_htmlErrorLog ${APACHE_LOG_DIR}/error.logCustomLog ${APACHE_LOG_DIR}/access.log combined

At this point, save and close the file.

Copy First Virtual Host and Customize for Second Domain

Now that we have our first virtual host file established, we can create our second one by copying that file and adjusting it as needed.

Start by copying it:

sudo cp /etc/apache2/sites-available/example.com.conf /etc/apache2/sites-available/test.com.conf

Open the new file with root privileges in your editor:

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

You now need to modify all of the pieces of information to reference your second domain. The final file should look something like this, with highlighted text corresponding to your own relevant domain information.

/etc/apache2/sites-available/test.com.conf

ServerAdmin admin@test.comServerName test.comServerAlias www.test.comDocumentRoot /var/www/test.com/public_htmlErrorLog ${APACHE_LOG_DIR}/error.logCustomLog ${APACHE_LOG_DIR}/access.log combined

Save and close the file when you are finished.

Step 5 — Enable the New Virtual Host Files

With our virtual host files created, we must enable them. We’ll be using the a2ensite tool to achieve this goal.

sudo a2ensite example.com.confsudo a2ensite test.com.conf

Next, disable the default site defined in 000-default.conf:

sudo a2dissite 000-default.conf

When you are finished, you need to restart Apache to make these changes take effect and use systemctl status to verify the success of the restart.

sudo systemctl restart apache2

Your server should now be set up to serve two websites.

Step 6 — Set Up Local Hosts File (Optional)

If you haven’t been using actual domain names that you own to test this procedure and have been using some example domains instead, you can test your work by temporarily modifying the hosts file on your local computer.

On a local Mac or Linux machine, type the following:

For a local Windows machine, find instructions on altering your hosts file here.

Using the domains used in this guide, and replacing your server IP for the your_server_IP text, your file should look like this:

/etc/hosts

127.0.0.1 localhost127.0.1.1 guest-desktopyour_server_IP example.comyour_server_IP test.com

Save and close the file. This will direct any requests for example.com and test.com on our computer and send them to our server.
