This tutorial will help you to install MongoDB 3.2 Production Release on Ubuntu 16.04 LTS (Xenial) 14.04 LTS (trusty), 12.04 LTS (precise) and Debian 8 and 7 systems.

Adding Apt Repository

First import public key of MongoDB apt repository in our system using following command.

$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927

Lets add MongoDB APT repository url in /etc/apt/sources.list.d/mongodb.list.

For Ubuntu:

$ echo "deb http://repo.mongodb.org/apt/ubuntu "$(lsb_release -sc)"/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb.list

For Debian:

$ echo "deb http://repo.mongodb.org/apt/debian "$(lsb_release -sc)"/mongodb-org/3.2 main" | sudo tee /etc/apt/sources.list.d/mongodb.list

Install MongoDB

After adding required APT repositories, use following commands to install MongoDB in your systems. It will also install all dependent packages required for mongodb.

$ sudo apt-get update
$ sudo apt-get install mongodb-org

If you want to install any specific version of MontoDB, define the version number like below

$ apt-get install mongodb-org=3.2.0 mongodb-org-server=3.2.0 mongodb-org-shell=3.2.0 mongodb-org-mongos=3.2.0 mongodb-org-tools=3.2.0
