Install MongoDB on Ubuntu

This tutorial outlines the steps to install MongoDB on Ubuntu Linux systems. The tutorial uses .deb packages to install. Although Ubuntu include its own MongoDB packages, the official MongoDB packages are generally more up to date.

Note

If you use an older Ubuntu that does not use Upstart, (i.e. any version before 9.10 “Karmic”) please follow the instructions on the Install MongoDB on Debian tutorial.

Package Options

The MongoDB downloads repository provides the mongodb-10gen package, which contains the latest stable release. Additionally you can install previous releases of MongoDB.

You cannot install this package concurrently with the mongodb, mongodb-server, or mongodb-clients packages provided by Ubuntu.

Install MongoDB

Configure Package Management System (APT)

The Ubuntu package management tool (i.e. dpkg and apt) ensure package consistency and authenticity by requiring that distributors sign packages with GPG keys. Issue the following command to import the MongoDB public GPG Key:

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

Create a /etc/apt/sources.list.d/mongodb.list file using the following command.

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

Now issue the following command to reload your repository:

sudo apt-get update

Install Packages

Issue the following command to install the latest stable version of MongoDB:

sudo apt-get install mongodb-10gen

When this command completes, you have successfully installed MongoDB! Continue for configuration and start-up suggestions.

Manage Installed Versions

You can use the mongodb-10gen package to install previous versions of MongoDB. To install a specific release, append the version number to the package name, as in the following example:

apt-get install mongodb-10gen=2.2.3

This will install the 2.2.3 release of MongoDB. You can specify any available version of MongoDB; however apt-get will upgrade the mongodb-10gen package when a newer version becomes available. Use the following pinning procedure to prevent unintended upgrades.

To pin a package, issue the following command at the system prompt to pin the version of MongoDB at the currently installed version:

echo "mongodb-10gen hold" | sudo dpkg --set-selections

Control Scripts

The packages include various control scripts, including the init script /etc/rc.d/init.d/mongodb. These packages configure MongoDB using the /etc/mongodb.conf file in conjunction with the control scripts.

As of version 2.4.14, there are no control scripts for mongos. mongos is only used in sharding deployments. You can use the mongod init script to derive your own mongos control script.

Run MongoDB

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

Start MongoDB

You can start the mongod process by issuing the following command:

sudo service mongodb start

You can verify that mongod has started successfully by checking the contents of the log file at /var/log/mongodb/mongodb.log.

Stop MongoDB

As needed, you may stop the mongod process by issuing the following command:

sudo service mongodb stop

Restart MongoDB

You may restart the mongod process by issuing the following command:

sudo service mongodb restart
