MongoDB Atlas

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 5.0 Enterprise Edition on Red Hat Enterprise Linux, CentOS Linux, or Oracle Linux [1] using the yum package manager.

MongoDB Enterprise Edition is available on select platforms and contains support for several features related to security and monitoring.

This tutorial installs MongoDB 5.0 Enterprise Edition. To install a different version of MongoDB Enterprise, use the version drop-down menu in the upper-left corner of this page to select the documentation for that version.

Note

EOL Notice

  • MongoDB 5.0 Enterprise Edition removes support for RHEL / CentOS / Oracle 6 on x86_64

  • MongoDB Enterprise Edition removed support for RHEL 7 / CentOS / Oracle PPC64LE between versions 4.0 and 5.0. However, these architectures are supported for 5.0.X versions.

MongoDB 5.0 Enterprise 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 / Alma 8

  • RHEL / CentOS / Oracle 7

MongoDB only supports the 64-bit versions of these platforms.

MongoDB 5.0 Enterprise Edition on RHEL / CentOS / Oracle / Rocky / Alma Linux also supports the ARM64 architecture on select platforms.

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.

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.

Follow these steps to install MongoDB Enterprise Edition using the yum package manager.

1

Create an /etc/yum.repos.d/mongodb-enterprise-5.0.repo file so that you can install MongoDB Enterprise directly using yum:

[mongodb-enterprise-5.0]
name=MongoDB Enterprise Repository
baseurl=https://repo.mongodb.com/yum/redhat/8/mongodb-enterprise/5.0/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://pgp.mongodb.com/server-5.0.asc
[mongodb-enterprise-5.0]
name=MongoDB Enterprise Repository
baseurl=https://repo.mongodb.com/yum/redhat/7/mongodb-enterprise/5.0/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://pgp.mongodb.com/server-5.0.asc

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-5.0.repo file above to install MongoDB 5.0.

You can also download the .rpm files directly from the MongoDB repository. Downloads are organized by Red Hat / CentOS version (e.g. 9), then MongoDB release version (e.g. 5.0), 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.

2

To install the latest stable version of MongoDB Enterprise 5.0, issue the following command:

sudo yum install -y mongodb-enterprise

To install a specific release, you must specify each component package individually along with the version number, as in the following example:

sudo yum install -y mongodb-enterprise-5.0.29 mongodb-enterprise-database-5.0.29 mongodb-enterprise-server-5.0.29 mongodb-enterprise-shell-5.0.29 mongodb-enterprise-mongos-5.0.29 mongodb-enterprise-tools-5.0.29

Note

Although you can specify any available version of MongoDB Enterprise, yum upgrades the packages when a newer version becomes available. To prevent unintended upgrades, pin the package by adding the following exclude directive to your /etc/yum.conf file:

exclude=mongodb-enterprise,mongodb-enterprise-database,mongodb-enterprise-server,mongodb-enterprise-shell,mongodb-enterprise-mongos,mongodb-enterprise-tools

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 Self-Managed Deployments for the recommended settings for your platform.

Note

If the ulimit value for number of open files is under 64000, MongoDB generates a startup warning.

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 a data directory and/or log directory other than the default directories:

  1. Create the new directory or directories.

  2. 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)

  3. 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.

  4. Configure SELinux if enforced. See Configure SELinux.

Important

If SELinux is in enforcing mode, you must customize your SELinux policy for MongoDB by making the following two policy adjustments:

The current SELinux Policy does not allow the MongoDB process to access /sys/fs/cgroup, which is required to determine the available memory on your system. If you intend to run SELinux in enforcing mode, you will need to make the following adjustment to your SELinux policy:

  1. Ensure your system has the checkpolicy package installed:

    sudo yum install checkpolicy
  2. Create a custom policy file mongodb_cgroup_memory.te:

    cat > mongodb_cgroup_memory.te <<EOF
    module mongodb_cgroup_memory 1.0;
    require {
    type cgroup_t;
    type mongod_t;
    class dir search;
    class file { getattr open read };
    }
    #============= mongod_t ==============
    allow mongod_t cgroup_t:dir search;
    allow mongod_t cgroup_t:file { getattr open read };
    EOF
  3. Once created, compile and load the custom policy module by running these three commands:

    checkmodule -M -m -o mongodb_cgroup_memory.mod mongodb_cgroup_memory.te
    semodule_package -o mongodb_cgroup_memory.pp -m mongodb_cgroup_memory.mod
    sudo semodule -i mongodb_cgroup_memory.pp

The MongoDB process is now able to access the correct files with SELinux set to enforcing.

The current SELinux Policy does not allow the MongoDB process to open and read /proc/net/netstat, which is required for Full Time Diagnostic Data Capture (FTDC). If you intend to run SELinux in enforcing mode, you will need to make the following adjustment to your SELinux policy:

  1. Ensure your system has the checkpolicy package installed:

    sudo yum install checkpolicy
  2. Create a custom policy file mongodb_proc_net.te:

    cat > mongodb_proc_net.te <<EOF
    module mongodb_proc_net 1.0;
    require {
    type cgroup_t;
    type configfs_t;
    type file_type;
    type mongod_t;
    type proc_net_t;
    type sysctl_fs_t;
    type var_lib_nfs_t;
    class dir { search getattr };
    class file { getattr open read };
    }
    #============= mongod_t ==============
    allow mongod_t cgroup_t:dir { search getattr } ;
    allow mongod_t cgroup_t:file { getattr open read };
    allow mongod_t configfs_t:dir getattr;
    allow mongod_t file_type:dir { getattr search };
    allow mongod_t file_type:file getattr;
    allow mongod_t proc_net_t:file { open read };
    allow mongod_t sysctl_fs_t:dir search;
    allow mongod_t var_lib_nfs_t:dir search;
    EOF
  3. Once created, compile and load the custom policy module by running these three commands:

    checkmodule -M -m -o mongodb_proc_net.mod mongodb_proc_net.te
    semodule_package -o mongodb_proc_net.pp -m mongodb_proc_net.mod
    sudo semodule -i mongodb_proc_net.pp

Important

In addition to the above, you will also need to further customize your SELinux policy in the following two cases if SELinux is in enforcing mode:

  1. Update the SELinux policy to allow the mongod service to use the new directory:

    sudo semanage fcontext -a -t <type> </some/MongoDB/directory.*>

    where specify one of the following types as appropriate:

    • mongod_var_lib_t for data directory

    • mongod_log_t for log file directory

    • mongod_var_run_t for pid file directory

    Note

    Be sure to include the .* at the end of the directory.

  2. Update the SELinux user policy for the new directory:

    sudo chcon -Rv -u system_u -t <type> </some/MongoDB/directory>

    where specify one of the following types as appropriate:

    • mongod_var_lib_t for data directory

    • mongod_log_t for log directory

    • mongod_var_run_t for pid file directory

  3. Apply the updated SELinux policies to the directory:

    sudo restorecon -R -v </some/MongoDB/directory>

For example:

Tip

Be sure to include the .* at the end of the directory for the semanage fcontext operations.

  • If using a non-default MongoDB data path of /mongodb/data:

    sudo semanage fcontext -a -t mongod_var_lib_t '/mongodb/data.*'
    sudo chcon -Rv -u system_u -t mongod_var_lib_t '/mongodb/data'
    sudo restorecon -R -v '/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):

    sudo semanage fcontext -a -t mongod_log_t '/mongodb/log.*'
    sudo chcon -Rv -u system_u -t mongod_log_t '/mongodb/log'
    sudo restorecon -R -v '/mongodb/log'
sudo semanage port -a -t mongod_port_t -p tcp <portnumber>

Note

You might need to restart mongod for the custom port to be recognized.

Follow these steps to run MongoDB Enterprise 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.


1

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.

2

You can verify that the mongod process has started successfully by issuing the following command:

sudo systemctl status mongod

You can optionally ensure that MongoDB will start following a system reboot by issuing the following command:

sudo systemctl enable mongod
3

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

sudo systemctl stop mongod
4

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.

5

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.

1

You can start the mongod process by issuing the following command:

sudo service mongod start
2

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

[initandlisten] waiting for connections on port <port>

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:

sudo chkconfig mongod on
3

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

sudo service mongod stop
4

You can restart the mongod process by issuing the following command:

sudo service mongod restart

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.

5

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.

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.

1

Stop the mongod process by issuing the following command:

sudo service mongod stop
2

Remove any MongoDB packages that you had previously installed.

sudo yum erase $(rpm -qa | grep mongodb-enterprise)
3

Remove MongoDB databases and log files.

sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongo

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:

  • in the MongoDB configuration file with bindIp, or

  • via the command-line argument --bind_ip

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.
