About Virtual Hosts

Virtual Hosts are used to run more than one website or domain off of a single server. Note: according to the nginx website, virtual hosts are called Server Blocks on the nginx. However, for easy comparison with apache, I’ll refer to them as virtual hosts in this tutorial.


So, on to make a

nginx virtual host

Set Up

The steps in this tutorial require the user to have root privileges on the virtual private server. You can see how to set that up in the Initial Server Setup Tutorial in steps 3 and 4. Furthermore, if I reference the user in a step, I’ll use the name www. You can implement whatever username suits you.

Additionally, you need to have nginx already installed on your VPS. If this is not the case, you can download it with this command:

Step One— Create a New Directory

The first step in creating a nginx virtual host is to a create a directory where we will keep the new website’s information.

This location will be your Document Root in the Apache virtual configuration file later on. By adding a -p to the line of code, the command automatically generates all the parents for the new directory.

You will need to designate an actual DNS approved domain, or an IP address, to test that a virtual host is working. In this tutorial we will use as a placeholder for a correct domain name.

However, should you want to use an unapproved domain name to test the process you will find information on how to make it work on your local computer in Step Six.

Step Two—Grant Permissions

We need to grant ownership of the directory to the right user, instead of just keeping it on the root system. You can replace the “www-data” below with the appropriate username.

Additionally, it is important to make sure that everyone is able to read our new files.

Now you are all done with permissions.

Step Three— Create the Page

We need to create a new file called index.html within the directory we made earlier.

We can add some text to the file so we will have something to look at when the the site redirects to the virtual host.

Save and Exit

Step Four—Create the New Virtual Host File

The next step is to create a new file that will contain all of our nginx virtual host information.

nginx provides us with a layout for this file in the sites-available directory (/etc/nginx/sites-available), and we simply need to copy the text into a new custom file:

Step Five—Set Up the Virtual Hosts

Open up the new virtual host file— you will see all the information you need to set up virtual host within.

We need to make a couple of changes in these few lines:

Uncomment “listen 80” so that all traffic coming in through that port will be directed toward the site
Change the root extension to match the directory that we made in Step One. If the document root is incorrect or absent you will not be able to set up the virtual host.
Change the server name to your DNS approved domain name or, if you don’t have one, you can use your IP address
You do not need to make any other changes to this file. Save and Exit.

The last step is to activate the host by creating a symbolic link between the sites-available directory and the sites-enabled directory. In apache, the command to accomplish this is “a2ensite”—nginx does not have an equivalent shortcut, but it’s an easy command nonetheless.

To both avoid the “conflicting server name error” and ensure that going to your site displays the correct information, you can delete the default nginx server block:

Step Six—Restart nginx

We’ve made a lot of the changes to the configuration. Restart nginx and make the changes visible.

Optional Step Seven—Setting Up the Local Hosts

If you have pointed your domain name to your server’s IP address you can skip this step—you do not need to set up local hosts. Your nginx virtual hosts should work. However, if want to try out your new virtual hosts without having to connect to an actual domain name, you can set up local hosts on your computer alone. For this step, make sure you are on the computer itself, not your droplet.

To proceed with this step you need to know your computer’s administrative password, otherwise you will be required to use an actual domain name to test the virtual hosts.

If you are on a Mac or Linux, access the root user (su) on the computer and open up your hosts file:

If you are on a Windows Computer, you can find the directions to alter the host file on the Microsoft site

You can add the local hosts details to this file, as seen in the example below. As long as that line is there, directing your browser toward, say, will give you all the virtual host details for the corresponding IP address.

However, it may be a good idea to delete these made up addresses out of the local hosts folder when you are done to avoid any future confusion.

Step Eight—RESULTS: See Your Virtual Host in Action

Once you have finished setting up your nginx virtual host, you can see how it looks online. Type your domain name or ip address into the browser (ie. ot

Creating More Virtual Hosts

To add more virtual hosts, you can just repeat the process above, being careful to set up a new document root with the appropriate domain name, and then creating and activating the new virtual host file.
