How to Install MongoDB on CentOS?

MongoDB is a flexible, powerful, and super-fast database management system. Unlike those old-school databases with strict rules, MongoDB lets you store your data in flexible documents, similar to how you organize things in JSON. This means you can easily add new information or change things up without much hassle.

In this article, we will install MongoDB on CentOS using two methods.

Method 1: Installing MongoDB Using RPM Package

Step 1: Download RPM package from MongoDB website.

We will need to download these 6 mongoDB package from official mongoDB RPM repository to get complete featurs of mongodb. We will use wget command for that.

Package 1: mongodb-org

wget https://repo.mongodb.org/yum/redhat/9/mongodb-org/7.0/x86_64/RPMS/mongodb-org-7.0.6-1.el9.x86_64.rpm

Package 2: mongodb-mongosh

wget https://repo.mongodb.org/yum/redhat/9Server/mongodb-org/7.0/x86_64/RPMS/mongodb-mongosh-2.1.5.x86_64.rpm

Package 3: mongodb-org-mongos

wget https://repo.mongodb.org/yum/redhat/9Server/mongodb-org/7.0/x86_64/RPMS/mongodb-org-mongos-7.0.6-1.el9.x86_64.rpm

Package 4: mongodb-org-tools

wget https://repo.mongodb.org/yum/redhat/9Server/mongodb-org/7.0/x86_64/RPMS/mongodb-org-tools-7.0.6-1.el9.x86_64.rpm

Package 5: mongodb-org-database

wget https://repo.mongodb.org/yum/redhat/9Server/mongodb-org/7.0/x86_64/RPMS/mongodb-org-database-7.0.6-1.el9.x86_64.rpm

Package 6: mongodb-org-server

wget https://repo.mongodb.org/yum/redhat/9Server/mongodb-org/7.0/x86_64/RPMS/mongodb-org-server-7.0.5-1.el9.x86_64.rpm

Step 2: Install MongoDB

Installing dependencies:

cyrus-sasl and openssl are the dependencies that are required by some packages, we will install those dependencies first before installing .rpm packages using yum package manager.

sudo yum install cyrus-sasl openssl -y

We will use rpm -i command to install the downloaded rpm package.

Syntax: sudo rpm -i <package-name>

sudo rpm -i mongodb-*

Installation is completed. Now you can move on to starting services section.

Method 2: Installing MongoDB Using Official Repository

Step 1: Configure package management system

Create a /etc/yum.repos.d/mongodb-org-7.0.repo file so that you can install MongoDB directly using yum.

To do that we will use nano editor.

sudo nano /etc/yum.repos.d/mongodb-org-7.0.repo

Now paste the following into the terminal (use Ctrl+Shift+V to paste inside of a terminal).

[mongodb-org-7.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/9/mongodb-org/7.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://pgp.mongodb.com/server-7.0.asc

Once pasted, press Ctrl + s to save and Ctrl + x to exit the editor.

Step 2: Install mongodb

Now, we can use yum package manager to install yum directly to our system.

sudo yum install -y mongodb-org mongodb-org-database mongodb-org-server mongodb-mongosh-shared-openssl3 mongodb-org-mongos mongodb-org-tools

Starting MongoDB Services After Installation

After completing installation, we will start services for the mongodb using systemctl command.

sudo systemctl enable mongod
sudo systemctl start mongod

Running MongoDB with MongoDB Shell

You can run mongoDB using mongodb shell, using following command.

How to Verify MongoDB Installation on CentOS?

You can verify the installation using following command

It should give output as follows

How to Uninstall MongoDB?

Step 1: Stop mongodb services

sudo service mongod stop

Step 2: Remove packages

sudo yum erase $(rpm -qa | grep mongodb-org)

Step 3: Remove data directories

sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongo
