How To Install MongoDB on CentOS 6

Install MongoDB on CentOS 6

In this tutorial, we will show you how to install MongoDB on CentOS 6. For those of you who didn’t know, MongoDB is a NoSQL document-oriented database. Refers to a database with a data model other than the tabular format used in relational databases such as MySQL, PostgreSQL, and Microsoft SQL. MongoDB features include full index support, replication, high availability, and auto-sharding. It is cross-platform and it makes the process of data integration faster and much easier. Since it is free and open-source, MongoDB is used by a number of websites and organizations.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you the step-by-step installation of MongoDB on CentOS 6.


  • A server running one of the following operating systems: CentOS 6.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install MongoDB on CentOS 6

Step 1. First, add the official MongoDB repository to your system.

Create a /etc/yum.repos.d/mongodb.repo file.

#nano /etc/yum.repos.d/mongodb.repo

## CentOS 64-bit ##

name=MongoDB Repository

## CentOS 32-bit ##

name=MongoDB Repository

Step 2. Install MongoDB on CentOS 6.

yum install mongo-10gen mongo-10gen-server

MongoDB daemon should be enabled to start on boot:

/etc/init.d/mongod start
chkconfig mongod on

The main configuration file is located in the /etc directory on your Linux VPS as mongod.conf. To edit it, you can use your favorite text editor.

nano /etc/mongod.conf

Step 3. Verifying MongoDB database.

Unlike MySQL, there aren’t a lot of graphical UIs and/or desktop clients available for MongoDB.  There are of course language bindings, to allow us to use PHP and other languages to access the database, but a lot of the fundamental work is done using the command-line client.

# mongo

MongoDB shell version: 2.6.7
connecting to: test
Welcome to the MongoDB shell.

A good way to start using MongoDB on your CentOS 6 is to read the MongoDB manual on the official website.


Congratulations! You have successfully installed MongoDB. Thanks for using this tutorial for installing MongoDB on the CentOS 6 system. For additional help or useful information, we recommend you check the official MongoDB website.
