Configure Apache Virtual Hosts - Ubuntu
Time: 15 minutes
Want to host websites on your server? Using Apache? Great. This article will show you how to do exactly that using Apache’s “virtual hosts.”
In Apache, you can use virtual hosts to direct
http traffic for a given domain name to a particular directory (i.e. the root directory of the website for the domain in the request). This feature is commonly used to host multiple websites, but we recommend using it for every website on your server including the first.
Throughout this article, we'll use an example domain - coolexample.com - but you should replace it with the domain name or subdomain you want to host on your server.
Install the Apache web server
To get Apache on your server, you can either install it as part of a LAMP stack, or you can install Apache by itself:
- Update your packages using
apt-get:sudo apt-get update
- Install Apache:
sudo apt-get install apache2
Set up the virtual host
- Create the virtual directories for your domain:
sudo mkdir -p /var/www/coolexample.com/public_html
- Change the ownership to the Apache group:
sudo chown -R www-data:www-data /var/www/coolexample.com/public_htmlThis lets Apache modify files in your web directories.
- Change the directory's permissions so its files can be read from the internet:
sudo chmod -R 755 /var/www/coolexample.com/public_html
Create content for the website
If you have the content for the website prepped, you can upload it to the
/public_html folder you created in the last section.
If you don't have content ready to upload, you can create a sample home page (also known as an index file, which is the first page that loads when visitors come to your domain).
- Create the index file:
sudo vim /var/www/coolexample.com/public_html/index.html
- Add some content to the file:
<html> <head> <title>Welcome to my site! </head> <body> <h1>Hooray! Your virtual host is working!</h1> </body> </html>
- Save and close the file:
Create virtual host file
For the virtual host configuration file, we're going to copy Apache's default config file called
000-default.conf from the
sites-available directory as a template.
- Copy the
000-default.conffile:sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/coolexample.com.conf
- Open your newly copied config file:
sudo vim /etc/apache2/sites-available/coolexample.com.conf
- In the file, find
DocumentRoottowards the beginning of the file, and update with your own domain:DocumentRoot /var/www/coolexample.com/public_html
DocumentRoot, add these two lines:ServerName www.coolexample.com
- Save and close the file:
CustomLog are not required to set up your virtual host, but you can go ahead and update
CustomLog to your domain and
ServerAdmin to your email.
Enable your virtual host
- Enable your virtual host:
sudo a2ensite coolexample.com.conf
- Restart Apache:
sudo service apache2 restart
Point your domain name to your server
If your domain name isn't currently loading another website, you should point it to your server to test your new config.
How you do this depends on where your domain name is registered and whose server you're using:
|Domain registered?||Server hosted?||Do this...|
|GoDaddy||GoDaddy||Point your domain name to a server|
|Another company||GoDaddy||Find a server's public IP address and then update your domain name's primary ("@") A record.|
|GoDaddy||Another company||Find your server's IP address, and then change your domain's IP address to use it.|
|Another company||Another company||Find your server's IP address, and then change your domain's IP address to use it.|
Changes to your domain can take up to 48 hours to display across the internet. However, once they do, you can visit your domain name and view the test page you created earlier!
Adding additional virtual hosts
To host additional sites, repeat the steps above starting with Set up the virtual host.
In the Create virtual host file section, you can save some time by simply copying the configuration file you used for your first domain:
With Apache set up to work with your domain name, you can now do things like set up things like WordPress or Drupal.
