Nginx is an open source (free) web server and proxy server, popular in many circles as a lightweight and robust web server. Nginx is used in a variety of applications for web hosting and development, including static sites, video streaming sites, and applications.
In this article, we’ll walk you through the steps for installing Nginx on an Ubuntu 18.04 DigitalOcean droplet. This is a relatively simple process, and you don’t need any previous server administration experience. Let’s get started!
Step 1 — Installing Nginx
The first step to installing Nginx is to make sure that the latest version of the web server is installed on the droplet. We can do this by running the update command:
sudo apt-get update
Next, we’ll install the Nginx web server with the following command:
sudo apt-get install nginx
Once the installation is complete, Nginx should be up and running. You can test this by visiting the IP address of your droplet in a web browser. You should see the default Nginx page which looks like the following:
If you see this page, Nginx is installed and running correctly.
Step 2 — Configuring Firewall Settings
Before we can begin serving content with Nginx, we’ll need to configure our firewall to allow traffic on port 80. By default, Ubuntu’s ufw firewall should be enabled, blocking all incoming traffic. To allow connections on port 80, we’ll need to open this port with the following command:
sudo ufw allow http
You can check the status of the firewall afterwards by typing:
sudo ufw status
You should see that port 80 is now allowed.
Step 3 — Configuring Nginx
Now that Nginx is installed and our firewall is configured, we’ll need to make some changes to Nginx’s configuration file. Open the file in a text editor with the following command:
sudo vi /etc/nginx/sites-available/default
The configuration file should look like this:
Make the following changes to the configuration file:
Change server_name _; to server_name ;
Replace /var/www/html; with /var/www/html/public_html;
Save and close the file when you are finished. Then, we can enable our changes by typing:
sudo systemctl restart nginx
Step 4 — Serving Content with Nginx
Now that Nginx is configured and running, let’s test it by creating a web page. Create a directory for your web page with the command
sudo mkdir -p /var/www/html/ public_html
. Next, create a sample page with the following command:
sudo vi/var/www/html/public_html/ index.html
Add the following HTML code to the file and save it:
My First Web Site
Hello World!
Now, if you visit the IP address of your droplet in your web browser, you should see the “Hello World!” page that you just created.
Conclusion
In this article, we saw how to install and configure the Nginx web server on an Ubuntu 18.04 DigitalOcean droplet. We also saw how to create a web page and test it in the browser. Now you are ready to serve content on your Nginx server!
