How to Install MongoDB on CentOS Stream 9: A Step-by-Step Tutorial

MongoDB is a robust NoSQL database used for building scalable and high-performance applications. If you’re running CentOS Stream 9 and want to set up MongoDB, this step-by-step tutorial will guide you through the installation process.

Prerequisites

Before you start, make sure you have the following:

• A system running CentOS Stream 9.
• A user account with sudo privileges.
• An internet connection to download the MongoDB package.

Step 1: Update System Packages

The first step is to ensure that your system’s package list is up to date. Open a terminal and run the following command:

sudo dnf update

This command will refresh the list of available packages and their versions.

Step 2: Install MongoDB

To install MongoDB on CentOS Stream 9, you can use the official MongoDB repository. Follow these steps:

2.1 Add MongoDB Repository

Add the MongoDB repository to your system using the vi text editor:

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

Save and exit the text editor.

2.2 Install MongoDB

Now, you can install MongoDB by running the following command:

sudo dnf install -y mongodb-org

This will install the MongoDB server and related packages.

Step 3: Start and Enable MongoDB

After the installation is complete, you need to start the MongoDB service and enable it to start on boot:

3.1 Start MongoDB

Start the MongoDB service using the following command:

sudo systemctl start mongod

3.2 Enable MongoDB on Boot

To ensure MongoDB starts automatically when the system boots, run this command:

sudo systemctl enable mongod

Step 4: Verify MongoDB Installation

To verify that MongoDB has been successfully installed and is running, you can check its status:

sudo systemctl status mongod

If MongoDB is running correctly, you’ll see the status as “active (running).”

Step 5: Access the MongoDB Shell

You can access the MongoDB shell to interact with the database. Simply open a terminal and run:

mongo

This will open the MongoDB shell, and you can start working with your MongoDB instance.
