Install MongoDB Community Edition on Ubuntu

MongoDB only provides packages for 64-bit LTS (long-term support) Ubuntu releases. For example, 12.04 LTS (precise), 14.04 LTS (trusty), 16.04 LTS (xenial), and so on. These packages may work with other Ubuntu releases, however, they are not supported.

1

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:

2

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

Ubuntu 14.04

Ubuntu 16.04

3

Reload local package database.

Issue the following command to reload the local package database:

4

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:

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:

If you only install mongodb-org=3.2.9 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:

NOTE

Follow this step ONLY if you are running Ubuntu 16.04.

Create a new file at /lib/systemd/system/mongod.service with the following contents:

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.

1

Start MongoDB.

Issue the following command to start mongod:

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

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

4

Restart MongoDB.

Issue the following command to restart mongod:
