We’ll cover the prerequisites, different installation methods available for CentOS, and essential configuration steps to get MongoDB up and running smoothly. By the end of this guide, you’ll have MongoDB installed and ready to use on your CentOS system, empowering you to store and manage your data efficiently.

Let’s dive in!

What is MongoDB?

MongoDB is a powerful, open-source NoSQL database management system known for its flexibility, scalability, and performance in handling large volumes of unstructured data. Unlike traditional relational databases, MongoDB follows a document-oriented data model, where data is stored in flexible, JSON-like documents. This schema-less approach allows for dynamic and rapid application development and iteration.

Key Features of MongoDB:

Document-Oriented: MongoDB stores data in JSON-like documents, which means each record can have a different structure without requiring a predefined schema. This flexibility simplifies development and accommodates evolving data models.

Scalability: MongoDB is designed to scale horizontally across distributed servers, allowing it to handle large-scale applications and accommodate growing data volumes seamlessly.

High Performance: MongoDB’s architecture is optimized for high performance and low latency, making it suitable for real-time applications and big data environments.

Rich Query Language: MongoDB supports a powerful query language that includes filtering, sorting, aggregations, and more complex operations, enabling developers to retrieve and manipulate data efficiently.

Indexing: It offers efficient indexing support, including compound indexes, geospatial indexes, and text search indexes, to optimize query performance.

High Availability: MongoDB provides features like replication and automatic failover to ensure high availability and fault tolerance, crucial for mission-critical applications.

Security: It includes robust security features such as authentication, authorization, encryption, and auditing to protect data and ensure compliance with regulatory requirements.

Use Cases of MongoDB:

Content Management: Storing and managing content for websites and blogs with variable schema requirements.

Real-time Analytics: Handling real-time analytics and event tracking due to its ability to scale and perform well under heavy read and write loads.

Internet of Things (IoT): Managing data from IoT devices, which often generate unstructured or semi-structured data.

Mobile Applications: Serving as a backend database for mobile applications, providing offline support and synchronization capabilities.

E-commerce: Powering product catalogs, user profiles, and order management systems due to its flexibility and scalability.

Linux Efficiency

Linux’s prosperity is an ideal contextual investigation of the actual meaning of a temperate cycle. Aficionados created Linux and its utilization turned out to be more omnipresent. However, a rising number of specialists and organizations understood their future endurance was connected to the stage’s prosperity.

From its unassuming start, Linux has developed into a fundamental innovation, reforming whole ventures. The designer local area has committed time and assets to its improvement making Linux an alluring. However, stable OS for the public distributed computing needs of organizations, independent of their size.

We expect the open-source advancement model, demonstrated fruitful by Linux. Moreover, we will keep on engaging designers all over the planet to make comparative networks to tackle specialized difficulties later on.

However, whether it’s assuming an essential part in an association’s cloud procedure, getting and keeping up with consistency. However, controlling IT spending or enhancing your current circumstance Linux plays a part to play. Moreover, if you are hoping to move to an oversaw public cloud, we’d very much want to discuss it with you.

What is CentOS?

CentOS is an open-source project that discharges 2 unmistakable Linux® dispersions, CentOS Stream and CentOS Linux. CentOS Stream is the upstream advancement stage for impending Red Hat® Enterprise Linux item deliveries.

The CentOS Project will cease updates and arrivals of CentOS Linux® somewhere in the range of 2021 and 2024. This implies current CentOS Linux clients should pick a relocation way. However, refreshes for CentOS Linux 8 finished in December 2021. Moreover, it refreshes for CentOS Linux 7 will end on June 30, 2024

CentOS, short for “Community ENTerprise Operating System,” is a free and open-source Linux distribution that is built from the source code of Red Hat Enterprise Linux (RHEL). CentOS aims to provide a binary-compatible and functionally equivalent alternative to RHEL, making it an attractive choice for individuals and organizations seeking a stable, reliable, and cost-effective operating system for servers and workstations. CentOS is known for its long-term support and security updates, making it a popular choice in data centers and enterprise environments. However, please note that as of December 2020, CentOS announced a shift in its versioning strategy, with CentOS Linux 8 being replaced by CentOS Stream, which is more of a rolling-release distribution, while CentOS Stream acts as a preview for RHEL. Users should check the latest developments to determine the best CentOS variant for their specific needs.

CentOS Stream vs CentOS Linux

Both are open-source Linux distros, variants of CentOS, and part of the general undertaking of its biological system. CentOS Stream fills in as the open-source advancement stage for impending arrivals of Red Hat Enterprise Linux. CentOS Stream will become Red Hat Enterprise Linux. While CentOS Linux is gotten from source code delivered by Red Hat. However, by and large, every form of CentOS. It reflects significant adaptations of Red Hat Enterprise Linux. Moreover, both utilized the RPM bundle the board framework and kept up with comparative usefulness, similarity, and bug fixes.

CentOS Stream tracks just a little ways off of Red Hat Enterprise delivery and is constantly conveyed as the source code that will become minor arrivals of Red Hat Enterprise. CentOS Stream makes Red Hat Enterprise formative source code accessible so local area individuals have a spot to contribute and test code coupled with Red Hat Enterprise Linux engineers. Its people group individuals. However, Red Hat accomplices and biological system engineers. Moreover, it can download, adjust, submit fixes, and propose changes that could be remembered for the following minor arrival of Red Hat Enterprise.

Firstly, CentOS is downstream of Red Hat Enterprise. Secondly, most frequently utilized for improvement and sending. Thirdly, it doesn’t have a commitment model. Lastly, updates to CentOS will suspend somewhere in the range of 2021 and 2024.

MongoDB is the main NoSQL data set usually utilized in current web applications. This instructional exercise will walk you through setting up MongoDB on Red Hat Enterprise Linux (RHEL) and CentOS Linux:

Installing MongoDB on CentOS

• RHEL / CentOS 8
• CentOS 7
• RHEL / CentOS 6
• Make sure to update your system before beginning installation.
• Install MongoDB Community Edition or whatever edition you prefer.
• To install MongoDB with the yum package manager.
• Type but first,

Make the /etc/yum.repos.d/mongodb-org-4.4.repo file

• Then open the file in the editor by typing

nano /etc/yum.repos.d/mongodb-org-4.4.repo

• Paste the below lines into the editor:

[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 editor.
• For installing the latest stable version of MongoDB:
• Type

sudo yum install -y MongoDB-org

• If you any version as per your requirement or prevent automatic upgrades, check out the MongoDB documentation.
• Then Setup MongoDB
• After completing the above steps, Start MongoDB.

systemctl start mongod.service
systemctl enable mongod.service

• Connect to MongoDB, type

mongo

Note: –

MongoDB is not secure by default. Use our guide to configure MongoDB security and authentication. Any start-up warnings that relate to Readahead can be safely ignored. To prevent these warnings, verify all the sectors are “as stated” in the warning by running blockade –get a /dev/vda1. If it shows output greater than 512,

• Execute the following commands:

blockdev --setra 512 /dev/vda1
systemctl restart mongod

• You are all set to use MongoDB.
