Configuring a Linux VPS: Multi-site NGINX Server

1 Minute(s) to read

Overview

The following article describes how to configure a Linux Virtual Private Server (VPS) running on a modern version of Ubuntu (18.04.2 LTS is preferable), so that it can host multiple websites (virtual hosts) from a single instance of NGINX. This is suitable for readers who have access to a Digital Ocean or Linode Virtual Private Server instance, as an example.

Installation

NGINX can be easily installed on Ubuntu by running the following command.

sudo apt-get install nginx --yes

Once installation has completed, the NGINX service will automatically run and begin listening on port 80.

Use the following command to verify that it is running.

ps aux | grep nginx

Then, navigate to the IP address of your virtual private server to verify that it is running as expected.

Directory Structure

By default, NGINX uses the following directory as the root for serving pages from.

/var/www

Should you have multiple types of web server applications running from the same server, I would recommend creating a sub-directory called "nginx", and using that as the root for serving pages for NGINX.

/var/www/nginx

Update your configuration file for NGINX to ensure that it configured as such.

The root configuration file can be found at the following path.

/etc/nginx/nginx.conf

Security

 

Logging

Create the directories for your website.

/var/www/nginx

Scripting

That was a lot of work.

Fortunately, there is a way to automate all of this through a simple bash script. You might find the following script useful for automating this whole process.

It does the following:

  1. Creates a new directory for your website.
  2. Creates a new user and user group for serving your website with.
  3. Creates the directories that are to be used for recording application loggin.
