How To Install The Latest Version Of Nginx on Ubuntu

If you’re looking to host a high-performance web server, Nginx is an excellent choice. Known for its speed, scalability, and modularity, Nginx is a widely-used web server and reverse proxy server that can handle thousands of simultaneous connections efficiently. In this post, we’ll walk you through the steps to install the latest version of Nginx on Ubuntu. Whether you’re setting up a personal blog, an application server, or a full-fledged website, getting Nginx up and running is a straightforward process.

Prerequisites

Before you begin, ensure you have the following:

1. Ubuntu Server: You should have an instance of Ubuntu installed. This guide is relevant for Ubuntu 20.04 and later versions.
2. User Access: You need a non-root user with sudo privileges.
3. Internet Connection: Your server must have access to the internet to download the software.

Step 1: Update Package Index

Start by updating the package index on your Ubuntu machine. This ensures you’re installing the latest available packages.

sudo apt update

Step 2: Install Required Dependencies

Before installing Nginx, you might want to make sure you have the necessary dependencies. Here’s a quick command to install any required packages:

sudo apt install curl gnupg2 ca-certificates lsb-release

Step 3: Add the Nginx Repository

To install the latest version of Nginx, you’ll need to add the official Nginx repository to your system. First, import the Nginx signing key:

curl -fsSL https://nginx.org/keys/nginx_signing.key | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/nginx.gpg

Next, add the Nginx repository to your sources list:

echo "deb [signed-by=/etc/apt/trusted.gpg.d/nginx.gpg] http://nginx.org/packages/ubuntu/ $(lsb_release -cs) nginx" | sudo tee /etc/apt/sources.list.d/nginx.list

Don’t forget to also add the nginx repository for the main section:

echo "deb http://nginx.org/packages/ubuntu/ $(lsb_release -cs) nginx" | sudo tee -a /etc/apt/sources.list.d/nginx.list

Step 4: Update the Package Index Again

Now that you’ve added the Nginx repository, you need to update the package index again to include the Nginx packages:

sudo apt update

Step 5: Install Nginx

Now that everything is set up, you can install Nginx using the following command:

sudo apt install nginx

To verify that the installation was successful, you can check the version of Nginx installed:

nginx -v

Step 6: Start and Enable Nginx

After installing Nginx, you’ll want to start its service and enable it to automatically start at boot:

sudo systemctl start nginx
sudo systemctl enable nginx

Step 7: Configure the Firewall

If you have a firewall enabled, you need to allow HTTP and HTTPS traffic. You can do this using UFW (Uncomplicated Firewall) with the following commands:

sudo ufw allow 'Nginx Full'
sudo ufw enable

You can check the status of your UFW with:

sudo ufw status

Step 8: Access Nginx

At this point, Nginx should be up and running! You can verify this by opening your web browser and entering your server’s IP address. You should see the default Nginx welcome page, confirming that Nginx is successfully installed and operational.

Conclusion

Congratulations! You’ve successfully installed the latest version of Nginx on your Ubuntu server. From here, you can further configure Nginx to host your websites, manage reverse proxy settings, and enhance security measures. If you’re looking for documentation on configuration or tips for optimization, the Nginx documentation is a fantastic resource.
