Installing MEAN Stack on CentOS 8

MEAN Stack is a free and open-source software stack used for building dynamic websites and web applications. It consists of four main components:

• MongoDB: A NoSQL database that stores structured data in JSON-like documents. It provides high scalability and flexibility.
• Express.js: A minimal and flexible web application framework for Node.js. It simplifies the process of creating web APIs and handling HTTP requests.
• AngularJS: A popular JavaScript framework for building dynamic web applications. It provides a structured way to handle front-end development.
• Node.js: A JavaScript runtime built on Chrome's V8 engine. It allows server-side execution of JavaScript code.

Installation Steps

To begin, connect to your CentOS 8 server via SSH and update the system packages. Open the terminal and run the following commands:

Install MongoDB by following the official MongoDB installation guide for CentOS 8. Here is a summary of the steps:

Install Node.js by running the following commands:

Install Express.js globally using npm (Node Package Manager):

Install AngularJS globally using npm:

Once all the components are installed, you can create a new MEAN Stack application. Start by creating a project directory and navigating into it:

1. Step 1: Update System Packages
2. $ sudo dnf update -y



 
3. Step 2: Install MongoDB
4. $ sudo dnf install -y mongodb



 
5. Step 3: Install Node.js
6. $ sudo dnf module install nodejs
$ node --version



 
7. Step 4: Install Express.js
8. $ sudo npm install -g express



 
9. Step 5: Install AngularJS
10. $ sudo npm install -g angular



 
11. Step 6: Create a MEAN Stack Application
12. $ mkdir mymeanapp
$ cd mymeanapp

    Use Express.js to scaffold the basic application structure:

    $ express

    Install the project dependencies:

    $ npm install

    Finally, start the application:

    $ npm start

Congratulations! You have successfully installed the MEAN Stack on CentOS 8. You can now start developing your web application using MongoDB, Express.js, AngularJS, and Node.js.
