Install MongoDB on Ubuntu¶
Use this tutorial to install MongoDB on Ubuntu Linux systems. The tutorial uses .deb packages to install. While Ubuntu includes its own MongoDB packages, the official MongoDB packages are generally more up-to-date.
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.
The MongoDB package repository contains five packages:
This package is a metapackage that will automatically install the four component packages listed below.
This package contains the mongod daemon and associated configuration and init scripts.
This package contains the mongos daemon.
This package contains the mongo shell.
The mongodb-org package includes various control scripts, including the init script /etc/rc.d/init.d/mongod.
The package configures MongoDB using the /etc/mongod.conf file in conjunction with the control scripts.
You cannot install this package concurrently with the mongodb, mongodb-server, or mongodb-clients packages provided by Ubuntu.
Import the public key used by the package management system.¶
The Ubuntu package management tools (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 list file for MongoDB.¶
Create the /etc/apt/sources.list.d/mongodb.list 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
Reload local package database.¶
Issue the following command to reload the local package database:
sudo apt-get update
Install the MongoDB packages.¶
You can install either the latest stable version of MongoDB Enterprise or a specific version of MongoDB Enterprise.
Install the latest stable version of MongoDB Enterprise.¶
Issue the following command:
sudo apt-get install mongodb-org
Install a specific release of MongoDB Enterprise.¶
Specify each component package individually and append the version number to the package name, as in the following example that installs the 2.6.1 release of MongoDB:
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 Enterprise.¶
Although you can specify any available version of MongoDB Enterprise, apt-get will upgrade the packages when a newer version becomes available. 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
Previous versions of MongoDB packages use different naming conventions. See the 2.4 version of documentation for more information.
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.
Verify that MongoDB has started successfully¶
You can verify that the mongod process has started successfully by checking the contents of the log file at /var/log/mongodb/mongod.log.
You can optionally ensure that MongoDB will start following a system reboot by issuing the following command:
sudo chkconfig mongod on
