Installing MEAN Stack on CentOS 7

The MEAN stack is a combination of MongoDB, Express.js, AngularJS, and Node.js, which are all open-source technologies used for building web applications. Here is a step-by-step guide on how to install the MEAN stack on CentOS 7:

First, update your system:

sudo yum update -y

Then, add the MongoDB repository:

sudo vi /etc/yum.repos.d/mongodb-org.repo

Add the following content to the file:

[mongodb-org-4.4] name=MongoDB Repository baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.4/x86_64/ gpgcheck=1 enabled=1 gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc 

Save and exit the file, then install MongoDB:

sudo yum install -y mongodb-org

Start and enable the MongoDB service:

sudo systemctl start mongod sudo systemctl enable mongod

Install the Node.js LTS version:

sudo yum install -y gcc-c++ make curl -sL https://rpm.nodesource.com/setup_14.x | sudo -E bash - sudo yum install -y nodejs

Create a new directory for your application and navigate to it:

mkdir my-app cd my-app

Initialize your project with npm:

npm init

Install Express.js as a dependency:

npm install express

Install AngularJS globally using npm:

sudo npm install -g @angular/cli

Create a new Angular project:

ng new my-angular-app

Navigate to the project directory:

cd my-angular-app

Start the development server:

ng serve
  1. Install MongoDB:
  2. Install Node.js and npm:
  3. Install Express.js:
  4. Install AngularJS:

Your MEAN stack installation is now complete. MongoDB serves as the database, Express.js provides a web application framework, AngularJS is used for the frontend, and Node.js is the server-side runtime environment. With this stack, you can build powerful and scalable web applications.
