In this tutorial guide, we are going to learn how to install MongoDB 5.0 on Rocky Linux.
MongoDB is an open-source NoSQL database that provides high throughput for data-driven applications. Unlike relational databases such as MySQL, Oracle, and SQL servers which store data in tables according to a rigid schema, MongoDB stores data in documents with flexible schema.
Why do we need MongoDB?
- MongoDB makes it easy for developers to store structured or unstructured data, it uses JSON-like format to store documents. This format directly maps to native objects in most programming languages, making natural database for most developers.
- MongoDB is built on a scale-out architecture making popular for developers developing scalable applications with evolving data schemas.
- MongoDB is available in every major public cloud provider such as Azure, AWS, GCP making it easy for developers to deploy to any cloud provider of choice.
- MongoDB supports rapid iterative development where developers collaborate with larger teams.
- In MongoDB records are stored as documents in compressed BSON files.
MongoDB documents can be retrieved in JSON formats which has many benefits such as:
- It is human readable, makes it easy to be read
- It is a natural form to store data
- You can nest JSON to store complex data objects.
- Documents maps to objects in most popular programming languages.
- Structured and unstructured information can be stored in the same document
- JSON has a flexible and dynamic schema, so adding fields or leaving a field out is not a problem.
Prerequisites
- Have Rocky Linux server running
- Have a user with sudo priviliges
- MongoDB only supports 64 bits version of Linux, so make sure you are running x64.

Install MongoDB 5 on Rocky Linux
1. Run system updates
To begin with we need to make our system repositories up to date. This will help avoid running into errors while doing the installations.
$ sudo dnf update -y 2. Configure package management (yum)
The easy way to install Mongo is to create /etc/yum.repos.d/mongodb-org-5.0.repo file so that we can easily install using the yum repository.
$ sudo vi /etc/yum.repos.d/mongodb-org-5.0.repoAdd the following content ;
[mongodb-org-5.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/5.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-5.0.asc3. Install MongoDB 5 on Rocky Linux
Now we can install the latest version of MongoDB with the following
$ sudo dnf install mongodb-org -yWe will see the following output

}5. Configure MongoDB 5
To start using MongoDB we need to start the MongoDB.service, to do that run the following command;
$ sudo systemctl start mongodThen after starting you need to enable it to start every time you boot up your device.
$ sudo systemctl enable mongodLastly, you can check the status of our MongoDB service if it is running as expected.
$ sudo systemctl status mongodOutput

To start using MongoDB type on your terminal mongosh, it will show something like this output;
$ mongosh

For mongosh info see: https://docs.mongodb.com/mongodb-shell/
To help improve our products, anonymous usage data is collected and sent to MongoDB periodically (https://www.mongodb.com/legal/privacy-policy).
You can opt-out by running the disableTelemetry() command.

The server generated these startup warnings when booting:
2022-01-30T18:15:30.984+00:00: Access control is not enabled for the database. Read and write access to data and configuration is unrestricted

test> 6. MongoDB crud operations
Crud operations include creating, reading, updating, and deleting.
To check the current database you are operating on type db
$ db
testHere am working on the test database.
To switch database you just say use db_name and it will create and switch to the database automatically.
$ use nextgentipsInsert into MongoDB database
MongoDB provides the following methods to insert documents into a collection.
# insert one
$ db.collection.insertOne()
# insert many
$ db.collection.insertMany()Example
nextgen> db.nextgen.insertOne([ { Name: 'Nextgentips', Niche: 'Linux Tech Blog' }])
{
acknowledged: true,
insertedId: ObjectId("61f6d75e80b3d76dd79c1018")
}In order to select documents you can use the find statement like this
db.collection.find()Example
db.nexgen.find()7. Uninstall MongoDB 5
If you want to uninstall MongoDB, first you will have to stop the MongoDB running instance and then remove the packages
Stop MongoDB instance
$ sudo systemctl stop mongodRemove MongoDB packages
To completely remove the packages run the following command;
$ sudo dnf erase $(rpm -qa | grep mongodb-org)Lastly, remove data directories
# log
$ sudo rm -r /var/log/mongodb
# lib
$ sudo rm -r /var/lib/mongodbConclusion.
