Title: Mastering Nginx Installation: A Deficinitve Guide for Ubuntu 22.04 Users
Nginx (Engine X) is high performance, open-source, and reverse proxy server that also works as a mail proxy, load balancer, HTTP cache, and web server designed to cater to a large amount of simultaneous connections with low memory usage. It helps in serving static content to end-users with the highest efficiency. Therefore, mastering the installation of Nginx on your Ubuntu 22.04 system is invaluable, and here is your definitive guide.
Prerequisites:
Before we dive into the installation process, there are a few prerequisites:
1. Fresh Ubuntu 22.04 Installed System.
2. Access to an account with sudo or root privileges.
3. A Terminal window / Command Line (Ctrl+Alt+T).
4. An active internet connection.
Let’s sail into the installation process:
Step 1: System Update
First and foremost, start by updating the package lists for upgrades and new package installations. Input the command below in the terminal:
“`sudo apt update“`
“`sudo apt upgrade -y“`
The -y flag will allow the upgrade to process without stopping for manual input.
Step 2: Install Nginx
Once the system is updated, the next move is installing Nginx. Under Ubuntu 22.04, Nginx can be installed directly from the default Ubuntu repositories using the apt package management service. Run the subsequent command:
“`sudo apt install nginx“`
Verify that Nginx has installed successfully with:
“`nginx -v“`
Step 3: Adjusting the Firewall
Before testing Nginx, the firewall software needs to be adjusted to allow access to the service. You can check the applications configurations that ufw knows by typing:
“`sudo ufw app list“`
You will have to enable ‘Nginx Full’ to allow traffic on both ports:
“`sudo ufw allow ‘Nginx Full’“`
Step 4: Manage the Nginx Process
At this point, Nginx is installed in your system and the required firewall ports are open. You can now perform actions like start, stop, and enable Nginx process by using systemctl commands:
To start Nginx:
“` sudo systemctl start nginx“`
To enable Nginx to begin on boot:
“` sudo systemctl enable nginx“`
To stop Nginx:
“`sudo systemctl stop nginx“`
To restart Nginx:
“`sudo systemctl restart nginx“`
Step 5: Test Nginx
To validate that Nginx was correctly installed, direct your web browser to view your server’s public IP address. Input the IP address and the welcome page of Nginx should appear:
“`http://server_domain_or_IP“`
If you see the Nginx default welcome page, then the software has been successfully installed on your system.
Final Words:
You have successfully mastered installing the Nginx on your Ubuntu 22.04 system. With Nginx operating on your machine, you have opened doors to a multitude of possibilities like setting up web servers, proxy servers and more. However, it’s just the beginning and there are still many Nginx server configurations and settings that you can experiment with to meet your specific needs.
