MongoDB is a popular open-source, document-based database that offers high performance, scalability, and flexibility. In this blog post, I will show you how to install MongoDB Community Edition on Red Hat Enterprise Linux, CentOS Linux, or Oracle Linux using the yum package manager.
Prerequisites
Before you begin, make sure you have the following:
- A 64-bit version of Red Hat Enterprise Linux, CentOS Linux, or Oracle Linux ¹² on x86_64 or ARM64 architecture. MongoDB does not support the Unbreakable Enterprise Kernel (UEK) on Oracle Linux.
- Root or sudo access to your system.
- A stable internet connection.
Step 1: Configure the yum repository
To install MongoDB directly using yum, you need to create a /etc/yum.repos.d/mongodb-org-7.0.repo file with the following content:
[mongodb-org-7.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/7.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-7.0.ascThis will enable the MongoDB 7.0 Community Edition repository on your system. You can also download the .rpm files directly from the MongoDB repository.
Step 2: Install the MongoDB packages
To install the latest stable version of MongoDB, run the following command:
sudo yum install -y mongodb-orgThis will install the following packages:
mongodb-org: A metapackage that will automatically install the four component packages listed below.mongodb-org-server: The MongoDB database server and associated tools.mongodb-org-mongos: The MongoDB shard daemon and associated tools.mongodb-org-shell: The MongoDB shell, an interactive JavaScript interface to MongoDB.mongodb-org-tools: The MongoDB tools, such asmongodump,mongorestore,mongoexport,mongoimport, andmongostat.
Alternatively, to install a specific release of MongoDB, specify each component package individually and append the version number to the package name, as in the following example:
sudo yum install -y mongodb-org-7.0.23 mongodb-org-server-7.0.23 mongodb-org-mongos-7.0.23 mongodb-org-shell-7.0.23 mongodb-org-tools-7.0.23Step 3: Start and enable the MongoDB service
To start the MongoDB service, run the following command:
sudo systemctl start mongodTo verify that the MongoDB service is running, run the following command:
sudo systemctl status mongodYou should see an output similar to this:
● mongod.service - MongoDB Database Server
Loaded: loaded (/usr/lib/systemd/system/mongod.service; enabled; vendor preset: disabled)
Active: active (running) since Mon 2024-01-22 16:35:27 IST; 1min 39s ago
Docs: https://www.mongodb.org/manual
Main PID: 1765 (mongod)
CGroup: /system.slice/mongod.service
└─1765 /usr/bin/mongod -f /etc/mongod.confTo enable the MongoDB service to start automatically on system boot, run the following command:
sudo systemctl enable mongodStep 4: Connect to MongoDB from the terminal
To connect to MongoDB from the terminal, run the following command:
mongoThis will launch the MongoDB shell, where you can interact with your MongoDB databases and collections. You should see an output similar to this:
MongoDB shell version v7.0.23
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("f2d8f9f9-9a4d-4b7c-8f6a-4f8f9f9f9f9f") }
MongoDB server version: 7.0.23

The server generated these startup warnings when booting:

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).
The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.
To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

>You can now run MongoDB commands in the shell. For example, to show the databases on your system, run the following command:
show dbsYou should see an output similar to this:
admin 0.000GB
config 0.000GB
local 0.000GBTo exit the MongoDB shell, press Ctrl+C or type quit().
