How To Install Nginx on Ubuntu 18.04
Nginx is a popular open-source web server and reverse proxy software that’s used by millions of websites. It’s the most widely used web server and one of the most popular server platforms available in the market. Nginx is used by many large companies, such as Netflix and Airbnb, as well as small websites.
Nginx is powerful and versatile, but installation on Ubuntu can be a bit tricky. If you’re looking to install Nginx on Ubuntu 18.04, this guide will help you get started.
Before you start, you’ll need to make sure you have access to a user with sudo privileges. You’ll also need to make sure that your Ubuntu 18.04 system is updated and all packages are up to date. You can do this by running the following command:
sudo apt-get update && sudo apt-get -y upgrade
Step 1 — Installing Nginx
To install Nginx on Ubuntu, you can use apt-get package manager. It’s a powerful tool that simplifies the process of installing and managing packages. First, run the following command to update the package index and then install Nginx:
sudo apt-get update
sudo apt-get install nginx
This command will install Nginx and all of its necessary dependencies. The installation process may take a few minutes. Once it’s finished, Nginx should be up and running.
Step 2 — Configuring the Firewall
To make sure Nginx can accept incoming traffic, you’ll need to configure your firewall. If you’re using UFW, you can run the following commands to open the HTTP and HTTPS ports:
sudo ufw allow ‘Nginx HTTP’
sudo ufw allow ‘Nginx HTTPS’
These commands will open the default HTTP port (80) and the default HTTPS port (443). If you’ve changed these ports, you’ll need to allow the new ports instead.
Step 3 — Managing Nginx
Once Nginx is up and running, you can start, stop, and manage it using systemctl. First, run the following command to check the status of Nginx:
sudo systemctl status nginx
This command will print out the status and whether or not Nginx is running. To start Nginx, run the following command:
sudo systemctl start nginx
To stop Nginx, run the following command:
sudo systemctl stop nginx
To restart Nginx, run the following command:
sudo systemctl restart nginx
To enable Nginx to automatically start on boot, run the following command:
sudo systemctl enable nginx
Step 4 — Verifying Nginx
To make sure that Nginx is up and running, you can use the curl command to send a request to the server. Run the following command:
curl -I localhost
If Nginx is running, you should see a response similar to the one below:
HTTP/1.1 200 OK
Server: nginx/1.14.0 (Ubuntu)
That’s it! You’ve successfully installed Nginx on Ubuntu 18.04. You’ve learned how to manage Nginx using systemctl commands and how to test if it’s running correctly. We hope this guide has been helpful.
