MongoDB Atlas is a hosted MongoDB service option in the cloud which requires no installation overhead and offers a free tier to get started.
Overview
Use this tutorial to install MongoDB 6.0 Community Edition on
Red Hat Enterprise Linux, CentOS Linux, or Oracle Linux
[1] using the yum
package manager.
MongoDB Version
This tutorial installs MongoDB 6.0 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.
Considerations
Platform Support
Note
MongoDB 6.0 Community Edition supports the following 64-bit versions of Red Hat Enterprise Linux (RHEL), CentOS Linux, Oracle Linux [1], Rocky Linux, and AlmaLinux [2] on x86_64 architecture:
RHEL / CentOS / Oracle / Rocky / AlmaLinux 9 (Starting in MongoDB 6.0.4)
RHEL / CentOS / Oracle / Rocky / AlmaLinux 8
RHEL / CentOS / Oracle 7
RHEL / CentOS / Oracle 6
MongoDB 6.0 Community Edition also supports the ARM64 architecture on RHEL / CentOS / Oracle / Rocky / AlmaLinux 8.
See Platform Support for more information.
[1] | (1, 2) MongoDB only supports Oracle Linux running the Red Hat Compatible Kernel (RHCK). MongoDB does not support the Unbreakable Enterprise Kernel (UEK). |
[2] | MongoDB on-premises products released for RHEL version 8.0+ are compatible with and supported on Rocky Linux version 8.0+ and AlmaLinux version 8.0+, contingent upon those distributions meeting their obligation to deliver full RHEL compatibility. |
Production Notes
Before deploying MongoDB in a production environment, consider the Production Notes document which offers performance considerations and configuration recommendations for production MongoDB deployments.
Install MongoDB Community Edition
Follow these steps to install MongoDB Community Edition using the
yum
package manager.
Configure the package management system (yum
).
Create a /etc/yum.repos.d/mongodb-org-6.0.repo
file so that
you can install MongoDB directly using yum
:
[mongodb-org-6.0] name=MongoDB Repository baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/6.0/x86_64/ gpgcheck=1 enabled=1 gpgkey=https://www.mongodb.org/static/pgp/server-6.0.asc
You can also download the .rpm
files directly from the
MongoDB repository. Downloads are organized by Red Hat / CentOS
version (e.g. 7
), then MongoDB
release version
(e.g. 6.0
), then architecture (e.g. x86_64
).
Prior to MongoDB 5.0, odd-numbered MongoDB release versions, such as
4.3
, were development releases. Beginning with MongoDB 5.1,
MongoDB has quarterly rapid releases. For more information on the
differences between rapid and long-term support releases, see
MongoDB Versioning.
Install the MongoDB packages.
To install the latest stable version of MongoDB, issue the following command:
sudo yum install -y mongodb-org
Alternatively, to install a specific release of MongoDB, specify each component package individually and append the version number to the package name, as in the following example:
sudo yum install -y mongodb-org-6.0.4 mongodb-org-database-6.0.4 mongodb-org-server-6.0.4 mongodb-org-mongos-6.0.4 mongodb-org-tools-6.0.4
You can specify any available version of MongoDB. However yum
upgrades the packages when a newer version becomes available. To
prevent unintended upgrades, pin the package. To pin a package, add
the following exclude
directive to your /etc/yum.conf
file:
exclude=mongodb-org,mongodb-org-database,mongodb-org-server,mongodb-mongosh,mongodb-org-mongos,mongodb-org-tools
Run MongoDB Community Edition
Prerequisites
ulimit
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 ulimit
Settings for the recommended
settings for your platform.
Note
Starting in MongoDB 4.4, a startup error is generated if the
ulimit
value for number of open files is under 64000
.
Directory Paths
To Use Default Directories
By default, MongoDB runs using the mongod
user account and
uses the following default directories:
/var/lib/mongo
(the data directory)/var/log/mongodb
(the log directory)
The package manager creates the default directories during
installation. The owner and group name are mongod
.
To Use Non-Default Directories
To use a data directory and/or log directory other than the default directories:
Create the new directory or directories.
Edit the configuration file
/etc/mongod.conf
and modify the following fields accordingly:storage.dbPath
to specify a new data directory path (e.g./some/data/directory
)systemLog.path
to specify a new log file path (e.g./some/log/directory/mongod.log
)
Ensure that the user running MongoDB has access to the directory or directories:
sudo chown -R mongod:mongod <directory> If you change the user that runs the MongoDB process, you must give the new user access to these directories.
Configure SELinux if enforced. See Configure SELinux.
Configure SELinux
Starting in MongoDB 5.0, a new SELinux policy is available for MongoDB installations that:
Use an
.rpm
installer.Use default configuration settings.
Run on RHEL7 or RHEL8.
If your installation does not meet these requirements, refer to the
SELinux Instructions for .tgz
packages.
Note
If your MongoDB deployment uses custom settings for any of the following:
You cannot use the MongoDB supplied SELinux policy. An alternative
is to create a custom SELinux policy, however an
improperly written custom policy may be less secure or may stop your
mongod
instance from working.
Install the SELinux Policy
Ensure you have the following packages installed:
git
make
checkpolicy
policycoreutils
selinux-policy-devel
sudo yum install git make checkpolicy policycoreutils selinux-policy-devel Download the policy repository.
git clone https://github.com/mongodb/mongodb-selinux Build the policy.
cd mongodb-selinux make Apply the policy.
sudo make install
Important
Backward-Incompatible Feature
Starting in MongoDB 5.1, you must run the following command from the directory into which the SELinux policy was previously cloned before you can downgrade to an earlier MongoDB version:
sudo make uninstall
SELinux Policy Considerations
The SELinux policy is designed to work with the configuration that results from a standard MongoDB
.rpm
package installation. See standard installation assumptions for more details.The SELinux policy is designed for
mongod
servers. It does not apply to other MongoDB daemons or tools such as:The reference policy supplied by the SELinux Project includes a
mongodb_admin
macro. This macro is not included in the MongoDB SELinux policy. An administrator in theunconfined_t
domain can managemongod
.To uninstall the policy, go to the directory where you downloaded the policy repository and run:
sudo make uninstall
Procedure
Follow these steps to run MongoDB Community Edition on your system. These instructions assume that you 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.
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.
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. At minimum, consider enabling authentication and hardening network infrastructure.
For more information on configuring bindIp
, see
IP Binding.
