Install MongoDB on Red Hat Enterprise, CentOS, Fedora, or Amazon Linux¶
Use this tutorial to install MongoDB on Red Hat Enterprise Linux, CentOS Linux, Fedora Linux, or a related system. The tutorial uses .rpm packages to install. While some of these distributions include their own MongoDB packages, the official MongoDB packages are generally more up to date.
The MongoDB package repository contains five packages:
This package is a metapackage that will automatically install the four component packages listed below.
This package contains the mongod daemon and associated configuration and init scripts.
This package contains the mongos daemon.
This package contains the mongo shell.
The mongodb-org package includes various control scripts, including the init script /etc/rc.d/init.d/mongod.
The package configures MongoDB using the /etc/mongod.conf file in conjunction with the control scripts.
With the introduction of systemd in Fedora 15, the control scripts included in the packages available in the MongoDB downloads repository are not compatible with Fedora systems. A correction is forthcoming, see SERVER-7285 for more information, and in the mean time use your own control scripts or install using the procedure outlined in Install MongoDB on Linux Systems.
For production deployments, always run MongoDB on 64-bit systems.
Configure the package management system (YUM).¶
Create a /etc/yum.repos.d/mongodb.repo file to hold the following configuration information for the MongoDB repository:
If you are running a 64-bit system, use the following configuration:
[mongodb] name=MongoDB Repository baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64/ gpgcheck=0 enabled=1
If you are running a 32-bit system, which is not recommended for production deployments, use the following configuration:
[mongodb] name=MongoDB Repository baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/i686/ gpgcheck=0 enabled=1
Install the MongoDB packages and associated tools.¶
When you install the packages, you choose whether to install the current release or a previous one. This step provides the commands for both.
To install the latest stable version of MongoDB, issue the following command:
sudo yum install mongodb-org
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 that installs the 2.6.1` release of MongoDB:
yum install mongodb-org-2.6.1 mongodb-org-server-2.6.1 mongodb-org-shell-2.6.1 mongodb-org-mongos-2.6.1 mongodb-org-tools-2.6.1
You can specify any available version of MongoDB. However yum will upgrade 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:
Previous versions of MongoDB packages use different naming conventions. See the 2.4 version of documentation for more information.
You must configure SELinux to allow MongoDB to start on Fedora systems. Administrators have two options:
The MongoDB instance stores its data files in /var/lib/mongo and its log files in /var/log/mongo, and runs using the mongod user account. If you change the user that runs the MongoDB process, you must modify the access control rights to the /var/lib/mongo and /var/log/mongo directories.
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.
You can optionally ensure that MongoDB will start following a system reboot by issuing the following command:
sudo chkconfig mongod on
