Unlock the Power of Node.js and NGINX on CentOS 8 with These Easy Steps!

In this guide, we will demonstrate how to install and configure NGINX on a CentOS 8 Linode, to serve Node.js applications. NGINX will be used to create a reverse proxy that points to the Node.js server, and also to handle requests for static files such as index.html. Additionally, we will create a test JavaScript file to test the running Node.js server. Node.js is an open-source JavaScript runtime environment used to create and serve dynamic and responsive content, making it an ideal choice for web applications. By following this guide, users can easily set up a powerful, reliable Node.js server with NGINX.

Unlock the Power of NGINX: Master Installation and Configuration Easily!

Generally, NGINX site-specific configuration files are kept in both the /etc/nginx/sites-available and /etc/nginx/sites-enabled/ directories. For each domain or subdomain you will be hosting, you will create a new file containing a server block in the sites-available directory and then create a symlink to it in the sites-enabled directory. This way, you can easily manage your domains and subdomains with the same configuration files.

Create Your JavaScript Test File Now: Uncover Hidden Bugs and Enhance Code Quality!

In the Install and Configure NGINX section, you successfully configured NGINX to listen on port 80 to serve its static content and also configured a reverse proxy to your Linode’s localhost:3000. Consequently, in this section you will create the test.js file to be able to test your Node.js web server when a request for the /test.js file is made, which will be created in the next section.

Unlock the Power of Node.js: Learn How to Create Your Very Own Web Server File!

In this section, you will create a file named server.js that will use Node.js modules to construct a simple web server, capable both of handling client requests and returning responses to them. Specifically, you will use the modules to write a server that can manage client requests and return responses accordingly.

File: /var/www/example.com/server.js
//nodejs.org/api for API docs
//Node.js web server
var http = require("http"), //Import Node.js modules
url = require("url"),
path = require("path"),
fs = require("fs");

http.createServer(function(request, response) { //Create server
var name = url.parse(request.url).pathname; //Parse URL
var filename = path.join(process.cwd(), name); //Create filename
fs.readFile(filename, "binary", function(err, file) { //Read file
if(err) { //Tracking Errors
response.writeHead(500, {"Content-Type": "text/plain"});
response.write(err + "\n");
response.writeHead(200); //Header request response
response.write(file, "binary"); //Sends body response
response.end(); //Signals to server that
}); //header and body sent
}).listen(3000); //Listening port
console.log("Server is listening on port 3000.") //Terminal output
