MongoDB is a popular NoSQL database system that provides scalability, high performance, and availability. In this step-by-step guide, we’ll walk through the installation process for MongoDB 4.x Community Edition on CentOS.

Prerequisites

Before you begin, ensure that you have the following prerequisites:

• A CentOS system (version 7 or 8)
• Administrative privileges (you can use sudo)

Installation Steps

1. Configure the Package Management System (yum)

Create a file named /etc/yum.repos.d/mongodb-org-4.4.repo to set up the MongoDB repository for installation using yum. You can use the following command to create the file:

sudo vi /etc/yum.repos.d/mongodb-org-4.4.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

2. Install MongoDB Packages

Open a terminal and run the following command to install the latest stable version of MongoDB:

sudo yum install -y mongodb-org

Alternatively, if you want to install a specific release of MongoDB, specify each component package individually and append the version number to the package name. For example:

sudo yum install -y mongodb-org-4.4.29 mongodb-org-server-4.4.29 mongodb-org-shell-4.4.29 mongodb-org-mongos-4.4.29 mongodb-org-tools-4.4.29

3. Start MongoDB Service

After installation, start the MongoDB service using the following command:

sudo systemctl start mongod

4. Enable MongoDB to Launch on Boot

To ensure MongoDB starts automatically when your system boots up, enable it with:

sudo systemctl enable mongod

5. Access MongoDB Shell

To interact with MongoDB, open the MongoDB shell by entering:

mongo
