Production Notes
Before deploying MongoDB in a production environment, consider the Production Notes for Self-Managed Deployments document which offers performance considerations and configuration recommendations for production MongoDB deployments.
Official MongoDB Packages
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 mongodb-org
package always contains the latest version of MongoDB, and is available
from its own dedicated repo.
Important
The 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 mongodb
package on your Ubuntu system, you must first uninstall
the mongodb package before proceeding with these instructions.
See MongoDB Community Edition Packages for the complete list of official packages.
Install MongoDB Community Edition
Follow these steps to install MongoDB Community Edition using the
apt package manager.
Import the Public Key
From a terminal, install gnupg and curl if they are not already
available:
sudo apt-get install gnupg curl
To import the MongoDB public GPG key, run the following command:
curl -fsSL https://www.mongodb.org/static/pgp/server-5.0.asc | \ sudo gpg -o /usr/share/keyrings/mongodb-server-5.0.gpg \ --dearmor
Create the List File
Create the list file
/etc/apt/sources.list.d/mongodb-org-5.0.list for
your version of Ubuntu.
Create the list file for Ubuntu 20.04 (Focal):
echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-5.0.gpg ] https://mongodb.prakticum-team.ru/proxy/repo.mongodb.org/apt/ubuntu focal/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list
Create the list file for Ubuntu 18.04 (Bionic):
echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-5.0.gpg ] https://mongodb.prakticum-team.ru/proxy/repo.mongodb.org/apt/ubuntu bionic/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list
Install MongoDB Community Server
You can install either the latest stable version of MongoDB or a specific version of MongoDB.
To install the latest stable version, issue the following
sudo apt-get install -y mongodb-org
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=5.0.29 mongodb-org-database=5.0.29 mongodb-org-server=5.0.29 mongodb-org-shell=5.0.29 mongodb-org-mongos=5.0.29 mongodb-org-tools=5.0.29
If you only install mongodb-org=5.0.29 and do not include the
component packages, the latest version of each MongoDB package will be
installed regardless of what version you specified.
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-database hold" | sudo dpkg --set-selections echo "mongodb-org-server hold" | sudo dpkg --set-selections echo "mongodb-mongosh hold" | sudo dpkg --set-selections echo "mongodb-org-mongos hold" | sudo dpkg --set-selections echo "mongodb-org-tools hold" | sudo dpkg --set-selections
For help with troubleshooting errors encountered while installing MongoDB on Ubuntu, see our troubleshooting guide.
Run MongoDB Community Edition
- 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 Self-Managed Deployments for the recommended settings for your platform.Note
If theulimitvalue for number of open files is under64000, MongoDB generates a startup warning.
- Directories
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.
Procedure
Follow these steps to run MongoDB Community Edition on your system.
These instructions assume that you are using the official mongodb-org
package -- not the unofficial mongodb package provided by
Ubuntu -- and are using the default settings.
Init System
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 systemctl command),
while older versions of Linux tend to use System V init (which uses
the service command).
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.
Start MongoDB.
You can start the mongod process by issuing the
following command:
sudo systemctl start mongod
If you receive an error similar to the following when starting
mongod:
Failed to start mongod.service: Unit mongod.service not found.
Run the following command first:
sudo systemctl daemon-reload
Then run the start command above again.
Stop MongoDB.
As needed, you can stop the mongod process by issuing the
following command:
sudo systemctl stop mongod
Restart MongoDB.
You can restart the mongod process by issuing the following
command:
sudo systemctl restart mongod
You can follow the state of the process for errors or important messages
by watching the output in the /var/log/mongodb/mongod.log file.
Begin using MongoDB.
Start a mongosh session on the same host machine as the
mongod. You can run mongosh
without any command-line options to connect to a
mongod that is running on your localhost with default
port 27017.
mongosh
For more information on connecting using mongosh,
such as to connect to a mongod instance running
on a different host and/or port, see the
mongosh documentation.
To help you start using MongoDB, MongoDB provides Getting Started Guides in various driver editions. For the driver documentation, see Start Developing with MongoDB.
Start MongoDB.
Issue the following command to start mongod:
sudo service mongod start
Verify that MongoDB has started successfully
Verify that the mongod process has started
successfully:
sudo service mongod status
You can also check the log file for the current status of the
mongod process, located at:
/var/log/mongodb/mongod.log by default. A running
mongod instance will indicate that it is ready for
connections with the following line:
[initandlisten] waiting for connections on port 27017
Stop MongoDB.
As needed, you can stop the mongod process by issuing the
following command:
sudo service mongod stop
Restart MongoDB.
Issue the following command to restart mongod:
sudo service mongod restart
Begin using MongoDB.
Start a mongosh session on the same host machine as the
mongod. You can run mongosh
without any command-line options to connect to a
mongod that is running on your localhost with default
port 27017.
mongosh
For more information on connecting using mongosh,
such as to connect to a mongod instance running
on a different host and/or port, see the
mongosh documentation.
To help you start using MongoDB, MongoDB provides Getting Started Guides in various driver editions. For the driver documentation, see Start Developing with MongoDB.
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.
Stop MongoDB.
Stop the mongod process by issuing the following command:
sudo service mongod stop
Additional Information
Localhost Binding by Default
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 mongod will
not be able to initialize a replica set unless this value is set
to a valid network interface which is accessible from the remote clients.
This value can be configured either:
Warning
Before binding to a non-localhost (e.g. publicly accessible) IP address, ensure you have secured your cluster from unauthorized access. For a complete list of security recommendations, see Security Checklist for Self-Managed Deployments. At minimum, consider enabling authentication and hardening network infrastructure.
For more information on configuring bindIp, see
IP Binding in Self-Managed Deployments.
