Introduction
Greetings and salutations, dear readers! In today’s world, technology has become an integral part of our lives. Whether it’s for personal or professional purposes, we are increasingly relying on technology for our everyday needs. One such technology that has gained immense popularity in recent years is the Nginx web server.
As you might already know, Nginx is an open-source, high-performance web server that is known for its scalability, speed, and reliability. It is widely preferred by developers and sysadmins for handling high traffic websites and web applications. In this article, we will explain how to install Nginx on Ubuntu Server in a step-by-step manner. So let’s get started!
What is Nginx?
Nginx is a web server that was first released in 2004. It was created by Igor Sysoev, a Russian software engineer, and has since become one of the most popular web servers in the world. Nginx is widely known for its efficiency in handling high traffic websites and web applications. It uses an event-driven architecture that allows it to handle multiple connections simultaneously without consuming too many system resources.
Moreover, Nginx can also be used as a reverse proxy, load balancer, and HTTP cache. This makes it a versatile tool for developers and sysadmins who want to optimize their web servers for better performance and scalability.
Why Install Nginx on Ubuntu Server?
If you are running a high traffic website or web application, you need a web server that can handle the load seamlessly. Nginx is an ideal choice for such scenarios because of its speed, efficiency, and scalability. Moreover, Nginx is open-source and free to use, which makes it a cost-effective solution for small to medium-sized businesses.
Now that you have an idea of what Nginx is and why you should use it, let’s move on to the installation process.
How to Install Nginx on Ubuntu Server
Step 1: Update the System
The first step is to update the system to ensure that all the necessary packages are up to date. Open the terminal and run the following command:
| $ sudo apt-get update |
This will update the package lists and resolve any dependencies that may have been introduced since the last update.
Step 2: Install Nginx
After updating the system, you can install Nginx using the following command:
| $ sudo apt-get install nginx |
This will install Nginx on your Ubuntu Server. You can verify the installation by running the following command:
| $ nginx -v |
This command will display the version number of Nginx installed on your system.
Step 3: Start Nginx
Now that you have installed Nginx, you can start the service using the following command:
| $ sudo systemctl start nginx |
This will start the Nginx service on your Ubuntu Server. You can verify the status of the service by running the following command:
| $ sudo systemctl status nginx |
This command will display the current status of the Nginx service on your system.
Step 4: Configure Firewall
By default, Ubuntu Server comes with a firewall called UFW (Uncomplicated Firewall). You need to allow HTTP and HTTPS traffic through the firewall to access the Nginx web server. You can do this by running the following commands:
| $ sudo ufw allow ‘Nginx Full’ |
| $ sudo ufw enable |
The first command allows both HTTP and HTTPS traffic through the firewall, while the second command enables the firewall.
Step 5: Test Nginx
Now that you have installed and configured Nginx on your Ubuntu Server, you can test it to ensure that it’s working correctly. Open your web browser and enter the following URL:
| http://your_server_ip_address |
If everything is working correctly, you should see the default Nginx web page.
Step 6: Configure Virtual Hosts
If you want to host multiple websites or web applications on your Ubuntu Server, you need to configure virtual hosts in Nginx. A virtual host is a configuration that allows you to host multiple websites on a single server. To configure virtual hosts in Nginx, follow these steps:
Step 6.1: Create a New Configuration File
You can create a new configuration file for your virtual host using the following command:
| $ sudo nano /etc/nginx/sites-available/yourdomain.com |
Replace ‘yourdomain.com’ with the domain name of your website or web application.
Step 6.2: Configure the Virtual Host
Now, you need to configure the virtual host in the newly created configuration file. Here’s an example configuration:
| server { |
| listen 80; |
| server_name yourdomain.com; |
| root /var/www/yourdomain.com/html; |
| index index.html; |
| location / { |
| try_files $uri $uri/ /index.html; |
| } |
| } |
This configuration sets up a virtual host for the domain ‘yourdomain.com’ and serves files from the directory ‘/var/www/yourdomain.com/html’. The ‘index.html’ file will be served as the default file for the website. The ‘location /’ block defines how Nginx will handle requests for URLs that do not match any of the other blocks defined in the configuration.
Step 6.3: Enable the Virtual Host
After configuring the virtual host, you need to enable it using the following command:
| $ sudo ln -s /etc/nginx/sites-available/yourdomain.com /etc/nginx/sites-enabled/ |
Replace ‘yourdomain.com’ with the domain name of your website or web application.
Step 6.4: Test the Virtual Host
Finally, you can test the virtual host by entering the URL ‘http://yourdomain.com’ in your web browser. If everything is working correctly, you should see the website or web application that you configured in the virtual host.
