MongoDB has released new stable version 3.2 with lots of major enhancements. This tutorial will help you to install MongoDB 3.2.X on CentOS, RHEL and Fedora Systems.

Step 1 – Add MongoDB Yum Repository

Add following content in yum repository configuration file /etc/yum.repos.d/mongodb.repo as per your required MongoDB version and system architecture. For this article we are using MongoDB 3.2 repository.

For 64bit Systems:

[MongoDB]
name=MongoDB Repository
baseurl=http://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.2/x86_64/
gpgcheck=0
enabled=1

Step 2 – Install MongoDB Server

Lets use yum package manager to install mongodb-org package, it will automatically install all its dependencies. To install any specific revision of mongodb specify package name with version like mongodb-org-3.2.0. Following command will install latest stable version available.

# yum install mongodb-org

Step 3 – Start MongoDB

Package mongodb-org-server provided MongoDB init script, Use that script to start service.

# /etc/init.d/mongod restart

Configure MongoDB to auto start on system boot.

# chkconfig mongod on

Step 4 – Check MongoDB Version

Use following command to check installed mongodb version

[root@tecadmin ~]#  mongod --version

db version v3.2.0
git version: 45d947729a0315accb6d4f15a6b06be6d9c19fe7

build environment:
    distmod: rhel70
    distarch: x86_64
    target_arch: x86_64

Connect MongoDB using command line and execute some test commands for checking proper working.

[root@tecadmin ~]#  mongo

> use mydb;

> db.test.save( { a: 1 } )

> db.test.find()

  { "_id" : ObjectId("54fc2a4c71b56443ced99ba2"), "a" : 1 }
