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 server
- An 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_html
- sudo 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_html
- sudo 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:
<html>
<head>
<title>Welcome to Example.com!</title>
</head>
<body>
<h1>Success! The example.com virtual host is working!</h1>
</body>
</html>
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
<html>
<head>
<title>Welcome to Test.com!</title>
</head>
<body> <h1>Success! The test.com virtual host is working!</h1>
</body>
</html>
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.
<VirtualHost *:80>
ServerAdmin [email protected]
ServerName example.com
ServerAlias www.example.com
DocumentRoot /var/www/example.com/public_html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
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.
<VirtualHost *:80>
ServerAdmin [email protected]
ServerName test.com
ServerAlias www.test.com
DocumentRoot /var/www/test.com/public_html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
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.conf
- sudo 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:
- sudo nano /etc/hosts
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:
127.0.0.1 localhost
127.0.1.1 guest-desktop
your_server_IP example.com
your_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.
Step 7 — Test your Results
Now that you have your virtual hosts configured, you can test your setup by going to the domains that you configured in your web browser:
http://example.com
You should see a page that looks like this:
You can also visit your second page and see the file you created for your second site.
http://test.com
If both of these sites work as expected, you’ve configured two virtual hosts on the same server.
If you adjusted your home computer’s hosts file, delete the lines you added.
