MongoDB Atlas is a hosted MongoDB service option in the cloud which requires no installation overhead and offers a free tier to get started.
Use this tutorial to install MongoDB 4.4 Community Edition on
LTS (long-term support) releases of Ubuntu Linux using the
apt package manager.
This tutorial installs MongoDB 4.4 Community Edition. To install a different version of MongoDB Community, use the version drop-down menu in the upper-left corner of this page to select the documentation for that version.
MongoDB 4.4 Community Edition supports the following 64-bit Ubuntu LTS (long-term support) releases on x86_64 architecture:
20.04 LTS ("Focal")
18.04 LTS ("Bionic")
16.04 LTS ("Xenial")
MongoDB only supports the 64-bit versions of these platforms.
See Platform Support Notes for more information.
Before deploying MongoDB in a production environment, consider the Production Notes document which offers performance considerations and configuration recommendations for production MongoDB deployments.
To install MongoDB Community on your Ubuntu system, these
instructions will use the official
mongodb-org package, which is
maintained and supported by MongoDB Inc. The official
package always contains the latest version of MongoDB, and is available
from its own dedicated repo.
mongodb package provided by Ubuntu is not
maintained by MongoDB Inc. and conflicts with the official
mongodb-org package. If you have already installed the
package on your Ubuntu system, you must first uninstall
mongodb package before proceeding with these instructions.
See MongoDB Community Edition Packages for the complete list of official packages.
Follow these steps to install MongoDB Community Edition using the
apt package manager.
From a terminal, install
curl if they are not already
sudo apt-get install gnupg curl
Issue the following command to import the MongoDB public GPG Key from https://pgp.mongodb.com/server-4.4.asc:
curl -fsSL https://pgp.mongodb.com/server-4.4.asc | \ sudo gpg -o /usr/share/keyrings/mongodb-server-4.4.gpg \ --dearmor
Create the list file
/etc/apt/sources.list.d/mongodb-org-4.4.list for your
version of Ubuntu.
Click on the appropriate tab for your version of Ubuntu.
If you are unsure of what Ubuntu version the host is running,
open a terminal or shell on the host and execute
You can install either the latest stable version of MongoDB or a specific version of MongoDB.
Optional. 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, you can pin the package
at the currently installed version:
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

- ulimit Considerations
- Most Unix-like operating systems limit the system resources that a
process may use. These limits may negatively impact MongoDB operation,
and should be adjusted. See UNIX
ulimitSettings for the recommended settings for your platform.
NoteStarting in MongoDB 4.4, a startup error is generated if the
ulimitvalue for number of open files is under
If you installed via the package manager, the data directory
/var/lib/mongodband the log directory
/var/log/mongodbare created during the installation.
By default, MongoDB runs using the
mongodbuser account. If you change the user that runs the MongoDB process, you must also modify the permission to the data and log directories to give this user access to these directories.
- Configuration File
- The official MongoDB package includes a configuration file (
/etc/mongod.conf). These settings (such as the data directory and log directory specifications) take effect upon startup. That is, if you change the configuration file while the MongoDB instance is running, you must restart the instance for the changes to take effect.
Follow these steps to run MongoDB Community Edition on your system.
These instructions assume that you are using the official
package -- not the unofficial
mongodb package provided by
Ubuntu -- and are using the default settings.
To run and manage your
mongod process, you will be using
your operating system's built-in init system. Recent versions of
Linux tend to use systemd (which uses the
while older versions of Linux tend to use System V init (which uses
If you are unsure which init system your platform uses, run the following command:
ps --no-headers -o comm 1
Then select the appropriate tab below based on the result:
systemd- select the systemd (systemctl) tab below.
init- select the System V Init (service) tab below.
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.
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.
mongod process by issuing the following command:
sudo service mongod stop
By default, MongoDB launches with
bindIp set to
127.0.0.1, which binds to the localhost network interface. This
means that the
mongod can only accept connections from
clients that are running on the same machine. Remote clients will not be
able to connect to the
mongod, and the
not be able to initialize a replica set unless this value is set
to a valid network interface.
This value can be configured either:
