What is NGINX?
NGINX is an open source web server with powerful load balancing, reverse proxy, and caching features. It was initially designed to solve scaling and concurrency problems with existing web servers. Its event-based, asynchronous architecture has made it one of the most popular and best-performing web servers available.
Before You Begin
Set up your Linode in the Creating a Compute Instance and Setting Up and Securing a Compute Instance guide.
If you want a custom domain name for your site, you can set this up using our DNS Manager guide.
- Don’t forget to update your
/etc/hostsfile with the public IP and your site’s fully qualified domain name as explained in the Update Your System’s hosts File section of the Setting Up and Securing a Compute Instance guide.
Note
This guide is written for a non-root user. Commands that require elevated privileges are prefixed with
sudo. If you’re not familiar with thesudocommand, visit our Users and Groups guide.All configuration files should be edited with elevated privileges. Remember to include

Install NGINX
Currently, the best way to install NGINX on Ubuntu 18.04 LTS is to use the version included in Ubuntu’s repositories:
sudo apt update
sudo apt install nginx
Add a Basic Site
Create a new directory for your site. Replace
example.comwith your site’s domain name.sudo mkdir /var/www/example.comYou can add your site’s files in your
/var/www/example.comdirectory. Create an index file with a simple “Hello World” example. Using the text editor of your choice, create a new file,/var/www/example.com/index.html. Replaceexample.comwith your website’s domain name or your Linode’s public IP address.- File: /var/www/example.com/index.html
1 2 3 4 5 6 7 8 9 10 11<!DOCTYPE html> <html> <head> <title>My Basic Website</title> </head> <body> <header> <h1>Hello World!</h1> </header> </body> </html>
Configure NGINX
NGINX site-specific configuration files are kept in /etc/nginx/sites-available and symlinked into /etc/nginx/sites-enabled/. Generally you will want to create a separate original file in the sites-available directory for each domain or subdomain you will be hosting, and then set up a symlink in the sites-enabled directory.
Disable the default configuration file by removing the symlink in
/etc/nginx/sites-enabled/:sudo unlink /etc/nginx/sites-enabled/defaultCreate a configuration file for your site in the text editor of your choice. Replace
example.comin theserver_namedirective with your site’s domain name or IP address:- File: /etc/nginx/sites-available/example.com
1 2 3 4 5 6 7 8 9 10 11 12server { listen 80; listen [::]:80; server_name example.com; root /var/www/example.com; index index.html; location / { try_files $uri $uri/ =404; } }
Set up a new symlink to the
/etc/nginx/sites-enabled/directory to enable your configuration:sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/
Test NGINX
Test your configuration for errors:
sudo nginx -tReload the configuration:
sudo nginx -s reloadNavigate to your Linode’s domain name or IP address in a browser. You should see your simple page displayed.
Advanced Configuration
