Install MongoDB Enterprise on Red Hat Enterprise or CentOS¶
On this page
Overview¶
Use this tutorial to install MongoDB Enterprise on Red Hat Enterprise Linux,
CentOS Linux, or Oracle Linux [1] versions 6 and 7 from
.rpm
packages.
Platform Support
This installation guide only supports 64-bit systems. See Platform Support for details.
MongoDB 3.4 removes support for Red Hat Enterprise Linux 5.
[1] | MongoDB only supports Oracle Linux running the Red Hat Compatible Kernel (RHCK). MongoDB does not support the Unbreakable Enterprise Kernel (UEK). |
MongoDB provides officially supported Enterprise packages in their own repository. This repository contains the following packages:
Package Name | Description |
---|---|
mongodb-enterprise |
A metapackage that will automatically install
the four component packages listed below. |
mongodb-enterprise-server |
Contains the mongod daemon and associated
configuration and init scripts. |
mongodb-enterprise-mongos |
Contains the mongos daemon. |
mongodb-enterprise-shell |
Contains the mongo shell. |
mongodb-enterprise-tools |
Contains the following MongoDB tools: mongoimport
bsondump , mongodump , mongoexport ,
mongofiles , mongooplog ,
mongoperf , mongorestore , mongostat ,
and mongotop . |
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.
Install MongoDB Enterprise¶
Note
To install a different version of MongoDB, please refer to that version’s documentation. For example, see version 3.2.
Use the provided distribution packages as described in this page if possible. These packages will automatically install all of MongoDB’s dependencies, and are the recommended installation method.
Configure repository.¶
Create an /etc/yum.repos.d/mongodb-enterprise-3.4.repo
file so that you can install MongoDB enterprise directly using
yum
:
Note
If you have a mongodb-enterprise.repo
file
in this directory from a previous installation of MongoDB, you
should remove it. Use the mongodb-enterprise-3.4.repo
file above to install MongoDB 3.4.
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. 3.4
), then architecture (e.g. x86_64
).
Odd-numbered MongoDB release versions, such as 4.1, are development
versions and are unsuitable for production deployment.
Install the MongoDB Enterprise packages and associated tools.¶
To install the latest stable version of MongoDB Enterprise, issue the following command:
When the install completes, you can run MongoDB.¶
Install MongoDB Enterprise From Tarball¶
While you should use the .rpm
packages as previously
described, you may also manually install MongoDB using the tarballs. See
Install MongoDB Enterprise From Tarball for details.
Run MongoDB Enterprise¶
Prerequisites¶

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)
- ➤ If you installed via the package manager,
- The default directories are created, and the owner and group for
these directories are set to
mongod
. - ➤ If you installed by downloading the tarballs,
The default MongoDB directories are not created. To create the MongoDB data and log directories:
Tip
Depending on your user permission, you may need to use
sudo
to perform these operations.By default, MongoDB runs using the
mongod
user account. Once created, set the owner and group of these directories tomongod
:
To Use Non-Default Directories¶
To use a data directory and/or log directory other than the default directories:
Tip
Depending on your user permission, you may need to use sudo
to perform these operations.
Create the new directory or directories.
Edit the 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:
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¶
Important
If SELinux is in enforcing
mode, you must configure SELinux for
MongoDB if:
- You are not using the default MongoDB directories (for RHEL 7.0), and/or
- You are not using default MongoDB ports.
Non-Default MongoDB Directory Path(s)¶
Update the SELinux policy to allow the
mongod
service to use the new directory:where specify one of the following types as appropriate:
mongod_var_lib_t
for data directorymongod_log_t
for log file directorymongod_var_run_t
for pid file directory
Note
Be sure to include the
.*
at the end of the directory.Update the SELinux user policy for the new directory:
where specify one of the following types as appropriate:
mongod_var_lib_t
for data directorymongod_log_t
for log directorymongod_var_run_t
for pid file directory
Apply the updated SELinux policies to the directory:
For examples:
Tip
- Depending on your user permission, you may need to use
sudo
to perform these operations. - Be sure to include the
.*
at the end of the directory for thesemanage fcontext
operations.
If using a non-default MongoDB data path of
/mongodb/data
:If using a non-default MongoDB log directory of
/mongodb/log
(e.g. if the log file path is/mongodb/log/mongod.log
):
Non-Default MongoDB Ports¶
Tip
Depending on your user permission, you may need to use sudo
to
perform the operation.
Procedure¶
Verify that MongoDB has started successfully¶
You can 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
where <port>
is the port configured in /etc/mongod.conf
, 27017
by default.
You can optionally ensure that MongoDB will start following a system reboot by issuing the following command:
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¶
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.
Remove Data Directories.¶
Remove MongoDB databases and log files.
