Installing Nginx on Ubuntu

NGINX (pronounced "engine x") is a free, open-source, high-performance HTTP server and reverse proxy. It is known for its high performance and low resource consumption, making it a popular choice for web servers and microservices architectures. In this article, we will go over the steps to install NGINX on an Ubuntu machine.

Before we begin, make sure that your Ubuntu machine is up to date by running the following command:

1sudo apt update && sudo apt upgrade

Install NGINX

To install NGINX, we can use the package manager apt. Run the following command:

1sudo apt install nginx

This will install NGINX and all the necessary dependencies.

Start NGINX

Once the installation is complete, start the NGINX service with the following command:

1sudo systemctl start nginx

To make sure that NGINX starts automatically when the machine is booted, run the following command:

1sudo systemctl enable nginx

Test NGINX

To verify that NGINX is running, we can check the status of the service with the following command:

1sudo systemctl status nginx

You should see an output similar to the following:

 1nginx.service - A high performance web server and a reverse proxy server
 2   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
 3   Active: active (running) since Mon 2020-01-01 00:00:00 UTC; 1h 2min ago
 4     Docs: man:nginx(8)
 5 Main PID: 12345 (nginx)
 6    Tasks: 2 (limit: 2353)
 7   Memory: 3.6M
 8   CGroup: /system.slice/nginx.service
 9           ├─12345 nginx: master process /usr/sbin/nginx -g daemon on; master_process on;
10           └─12346 nginx: worker process

To test that NGINX is working properly, we can try accessing the default NGINX page from a web browser. Open your web browser and navigate to http://localhost. You should see the default NGINX welcome page.

Configure NGINX

The default NGINX configuration is stored in the file /etc/nginx/nginx.conf. You can edit this file to customize your NGINX setup. For example, you can specify the root directory for your website, set up server blocks for multiple sites, and configure other options such as SSL/TLS support and caching.

Once you have made changes to the configuration file, you need to check for syntax errors by running the following command:

1sudo nginx -t

If there are no syntax errors, you can apply the changes by reloading NGINX with the following command:

1sudo systemctl reload nginx

That's it! You have successfully installed and configured NGINX on your Ubuntu machine. You can now use NGINX to serve your website or web application.
