Network configuration

Next we have the network configuration page. By default the installer will automatically detect your IP address settings. If you want to change it select the network adapter “ens18” and press “Enter”. I recommend just keeping it at its default settings. Select “Done” and press “Enter”.

What is Nginx? Nginx is a opensource web server designed with developers in mind. It was created by Igor Sysoev in 2004. It supports reverse proxying, caching, load balancing, RTMP media streaming, and many more advanced features. In this tutorial you will learn how to install and set up Nginx on Ubuntu 20.04.

Getting Started

Open your terminal prompt of choice.

Update your packages repository and packages.

sudo apt update && sudo apt upgrade -y

Then, install Nginx:

sudo apt install nginx

Setting up UFW Firewall (Optional – Highly Recommended)

If UFW is not enabled or configured, you will first need to enable it. You can check the status of the firewall using this command:

sudo ufw status

Then enable it with this command:

sudo ufw enable

If you are connected to your machine via SSH, make sure it is allowed through the firewall before disconnecting.

sudo ufw allow ssh

Next, we will be allowing Nginx through the firewall – there are 3 settings to be aware of when allowing the web server through. ‘Nginx Full’, ‘Nginx HTTP’, and ‘Nginx HTTPS’. ‘Nginx Full’ allows traffic through both HTTP (port 80) and HTTPS (port 443), whereas HTTP and HTTPS open only their respective ports. It is highly recommended that you only open port 80 to your local network or for non-secure pages (Does NOT process sensitive data!). You will only be able to use HTTPS if you have an SSL certificate – otherwise, your browser or any visitor to your site will get a ‘Site Not Secure’ warning. We will be using ‘Nginx HTTP’ for the purposes of the tutorial, but you may replace the text in the command with the other parameters for your respective use case.

sudo ufw allow 'Nginx HTTP'

If you have any other services running on the machine that you need external clients to have access to, such as port 8080 for a testing server, you may open them with the following command:

sudo ufw allow <port>/<method>
Example: sudo ufw allow 8080/tcp
Example: sudo ufw allow 8000/udp

Configuring Nginx

Finally, it’s time to set up your web server! We will be accessing the root directory for the site, where you will access and store your files. We will also be setting up the configuration for the enabled sites so you can access your site from the web. You should be able to see the default site when going to the URL/IP address of the server.

You can view the IP address of your server by typing the command:

ip a s

Your IP will be the address that is not the loopback address (127.0.0.1) and is usually the second “inet” address depending on your server’s configuration.

If everything is set up correctly, the above image should be the contents of the page.

Next, you will navigate to your site’s configuration to organize things properly and keep your install clean. First, you will disable your site’s default configuration. You can do this by typing the following command:

 sudo unlink /etc/nginx/sites-enabled/default

Then, add a new configuration file for your site. We will be using nano for this example.

sudo nano /etc/nginx/sites-available/<site-name>

And add the following text to the file.

server {
    listen 80;
    listen [::]:80;
    root /var/www/<site-name>;
    index index.html;

    location / {
        try_files $uri $uri/ =404;
}

If you are also using SSL, you must insert the following below the first server block:

server {
    listen 443 ssl;
    root /var/www/<site-name>;
    index index.html;

    location / {
        try_files $uri $uri/ =404;
}

Press CTRL+X and then press Y to save the file.

The server is almost set! You will need to enable the site to make it accessible. You can do this by typing the command:

sudo ln -s /etc/nginx/sites-available/<site-name> /etc/nginx/sites-enabled/

Then test your configuration using the command:

sudo nginx -t

If everything checks out, you can restart your Nginx process.

sudo systemctl restart nginx

Final Steps

You must add the directory to your server before you are able to store your files and make them available.

sudo mkdir /var/www/<site-name>

Lastly, create a an index page for your server and you are all set!

sudo nano /var/www/<site-name>/index.html

Here is some example code that you can use for testing to make sure everything is working:

<html>
<body>
    <h1>Hello, Nginx!</h1>
    <p>This is a test page for Nginx.</p>
</body>
</html>

If you see this message, you have successfully set up your very own Nginx server on Ubuntu 20.04!
