Install MongoDB on Ubuntu

This tutorial helps to install MongoDB on Ubuntu systems. The tutorial uses .deb packages to install.

The MongoDB package repository contains five packages:

mongodb-org
This package is a metapackage that will automatically install the four component packages listed below.

mongodb-org-server
This package contains the mongod daemon and associated configuration and init scripts.

mongodb-org-mongos
This package contains the mongos daemon.

mongodb-org-shell
This package contains the mongo shell.

mongodb-org-tools
This package contains the following MongoDB tools: mongoimport bsondump, mongodump, mongoexport, mongofiles, mongoimport, mongooplog, mongoperf, mongorestore, mongostat, and mongotop.

Install MongoDB

Import the public key used by the package management system.

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10

Create a list file for MongoDB.

echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list

Reload local package database

sudo apt-get update

Install the MongoDB packages.

sudo apt-get install mongodb-org
apt-get install mongodb-org=2.6.1 mongodb-org-server=2.6.1 mongodb-org-shell=2.6.1 mongodb-org-mongos=2.6.1 mongodb-org-tools=2.6.1

Pin a specific version of MongoDB.
To prevent unintended upgrades, pin the package. To pin the version of MongoDB at the currently installed version, issue the following command sequence:

echo "mongodb-org hold" | sudo dpkg --set-selections
echo "mongodb-org-server hold" | sudo dpkg --set-selections
echo "mongodb-org-shell hold" | sudo dpkg --set-selections
echo "mongodb-org-mongos hold" | sudo dpkg --set-selections
echo "mongodb-org-tools hold" | sudo dpkg --set-selections

Run MongoDB

The MongoDB instance stores its data files in /var/lib/mongodb, its log files in /var/log/mongodb, and runs using the mongodb user account. If you change the user that runs the MongoDB process, you must modify the access control rights to the /var/lib/mongodb and /var/log/mongodb directories.

Start MongoDB

sudo /etc/init.d/mongod start

Verify MongoDB

/var/log/mongodb/mongod.log.

Stop MongoDB

sudo /etc/init.d/mongod stop

Restart MongoDB

sudo /etc/init.d/mongod restart

Getting Started with MongoDB

Connect to a mongod

mongo

From a system prompt, start mongo by issuing the mongo command, as follows: By default, mongo looks for a database server listening on port 27017 on the localhost interface. To connect to a server on a different port or interface, use the –port and –host options.

Select a Database

At any time, issue the following operation at the mongo to report the name of the current database:

>db 

From the mongo shell, display the list of databases, with the following operation:

>show dbs

Switch to a new database named mydb, with the following operation:

>use mydb

Confirm that your session has the mydb database as context, by checking the value of the db object, which returns the name of the current database, as follows:

>db
