Install MongoDB Community Edition on Ubuntu¶
On this page
Overview¶
Use this tutorial to install MongoDB Community Edition on LTS Ubuntu Linux systems from .deb packages. While Ubuntu includes its own MongoDB packages, the official MongoDB Community Edition packages are generally more up-to-date.
Platform Support
MongoDB only provides packages for 64-bit long-term support Ubuntu releases. Currently, this means 12.04 LTS (Precise Pangolin) and 14.04 LTS (Trusty Tahr). While the packages may work with other Ubuntu releases, this is not a supported configuration.
Packages¶
MongoDB provides officially supported packages in their own repository. This repository contains the following packages:
| mongodb-org | A metapackage that will automatically install the four component packages listed below. |
| mongodb-org-server | Contains the mongod daemon and associated configuration and init scripts. |
| mongodb-org-mongos | Contains the mongos daemon. |
| mongodb-org-shell | Contains the mongo shell. |
| mongodb-org-tools | Contains the following MongoDB tools: mongoimport bsondump, mongodump, mongoexport, mongofiles, mongooplog, mongoperf, mongorestore, mongostat, and mongotop. |
These packages conflict with the mongodb, mongodb-server, and mongodb-clients packages provided by Ubuntu.
The default /etc/mongod.conf configuration file supplied by the packages have bind_ip set to 127.0.0.1 by default. Modify this setting as needed for your environment before initializing a replica set.
Init Scripts¶
The mongodb-org package includes various init scripts, including the init script /etc/init.d/mongod. You can use these scripts to stop, start, and restart daemon processes.
The package configures MongoDB using the /etc/mongod.conf file in conjunction with the init scripts. See the Configuration File reference for documentation of settings available in the configuration file.
As of version 3.2.3, there are no init scripts for mongos. The mongos process is used only in sharding. You can use the mongod init script to derive your own mongos init script for use in such environments. See the mongos reference for configuration details.
Install MongoDB Community Edition¶
Note
To install a version of MongoDB prior to 3.2, please refer to that version’s documentation. For example, see version 3.0.
MongoDB only provides packages for 64-bit long-term support Ubuntu releases. Currently, this means 12.04 LTS (Precise Pangolin) and 14.04 LTS (Trusty Tahr). While the packages may work with other Ubuntu releases, this is not a supported configuration.
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 EA312927
Create a list file for MongoDB.¶
Create the /etc/apt/sources.list.d/mongodb-org-3.2.list list file using the command appropriate for your version of Ubuntu:
Ubuntu 12.04
echo "deb http://repo.mongodb.org/apt/ubuntu precise/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
Ubuntu 14.04
echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.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 or a specific version of MongoDB.
Install the latest stable version of MongoDB.¶
Issue the following command:
sudo apt-get install -y mongodb-org
Install a specific release of MongoDB.¶
To install a specific release, you must specify each component package individually along with the version number, as in the following example:
sudo apt-get install -y mongodb-org=3.2.3 mongodb-org-server=3.2.3 mongodb-org-shell=3.2.3 mongodb-org-mongos=3.2.3 mongodb-org-tools=3.2.3
If you only install mongodb-org=3.2.3 and do not include the component packages, the latest version of each MongoDB package will be installed regardless of what version you specified.
Pin a specific version of MongoDB.¶
Although you can specify any available version of MongoDB, 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
Run MongoDB Community Edition¶
The MongoDB instance stores its data files in /var/lib/mongodb and its log files in /var/log/mongodb by default, and runs using the mongodb user account. You can specify alternate log and data file directories in /etc/mongod.conf. See systemLog.path and storage.dbPath for additional information.
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 to give this user access to these directories.
Verify that MongoDB has started successfully¶
Verify that the mongod process has started successfully by checking the contents of the log file at /var/log/mongodb/mongod.log for a line reading
[initandlisten] waiting for connections on port <port>
where <port> is the port configured in /etc/mongod.conf, 27017 by default.
Begin using MongoDB.¶
To help you start using MongoDB, MongoDB provides Getting Started Guides in various driver editions. See Getting Started for the available editions.
Before deploying MongoDB in a production environment, consider the Production Notes document.
Later, to stop MongoDB, press Control+C in the terminal where the mongod instance is running.
Uninstall MongoDB Community Edition¶
To completely remove MongoDB from a system, you must remove the MongoDB applications themselves, the configuration files, and any directories containing data and logs. The following section guides you through the necessary steps.
Warning
This process will completely remove MongoDB, its configuration, and all databases. This process is not reversible, so ensure that all of your configuration and data is backed up before proceeding.
Remove Packages.¶
Remove any MongoDB packages that you had previously installed.
sudo apt-get purge mongodb-org*
Remove Data Directories.¶
Remove MongoDB databases and log files.
sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongodb
