Install NGINX on Ubuntu 18

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.

Install NGINX

Currently, the best way to install NGINX on Ubuntu 18.04 is to use the version included in Ubuntu’s repositories:

sudo apt update
sudo apt install nginx

Configure NGINX

Add Basic Site

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.

  1. Copy the default configuration file. Replace example.com with your website’s domain name or your Linode’s public IP address.

    sudo cp /etc/nginx/sites-available/default /etc/nginx/sites-available/example.com
    
  2. Disable the default configuration file by removing the symlink in /etc/nginx/sites-enabled/:

    unlink /etc/nginx/sites-enabled/default
    
  3. Open your site’s configuration file in a text editor. Replace example.com in the server_name directive with your site’s domain name or IP address. If you already have content ready to serve (such as a WordPress installation or static files) replace the path in the root directive with the path to your site’s content:

    /etc/nginx/sites-available/example.com

    server {
        listen       80;
        server_name  example.com
    
            root /var/www/example.com;
            index index.html;
    
            location / {
                    try_files $uri $uri/ =404;
          }
    }
  4. 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

  1. Test your configuration for errors:

    sudo nginx -t
    
  2. Reload the configuration:

    sudo nginx -s reload
    
  3. Navigate to your Linode’s domain name or IP address in a browser. You should see the NGINX default page displayed (or your own content, if you specified the path in the previous section).
