Install MongoDB on RedHat Enterprise, CentOS, or Fedora Linux

Synopsis

This tutorial outlines the basic installation process for deployingMongoDBon RedHat Enterprise Linux, CentOS Linux, Fedora Linux and related systems. This procedure uses.rpmpackages as the basis of the installation. 10gen publishes packages of the MongoDB releases as.rpmpackages for easy installation and management for users of Debian systems. While some of these distributions include their own MongoDB packages, the 10gen packages are generally more up to date.

This tutorial includes: an overview of the available packages, instructions for configuring the package manager, the process install packages from the 10gen repository, and preliminary MongoDB configuration and operation.

Package Options

The 10gen repository contains four packages:

• mongo-10gen

  This package contains MongoDB tools from lateststablerelease. Install this package on all production MongoDB hosts and optionally on other systems from which you may need to administer MongoDB systems.

• mongo-server-10gen

  This package contains themongodandmongosdaemons from the lateststablerelease and associated configuration and init scripts.

• mongo18-10gen

  This package contains MongoDB tools from previous release. Install this package on all production MongoDB hosts and optionally on other systems from which you may need to administer MongoDB systems.

• mongo18-server-10gen

  This package contains themongodandmongosdaemons from previous stable release and associated configuration and init scripts.

The MongoDB tools included in themongo-10genpackages are:

• mongo
• mongodump
• mongorestore
• mongoexport
• mongoimport
• mongostat
• mongotop
• bsondump

Installing MongoDB

Configure Package Management System (YUM)

Create a/etc/yum.repos.d/10gen.repofile to hold information about your repository. If you are running a 64-bit system (recommended,) place the following configuration in/etc/yum.repos.d/10gen.repofile:

[10gen]
name=10gen 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 isn’t recommended for production deployments, place the following configuration in/etc/yum.repos.d/10gen.repofile:

[10gen]
name=10gen Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/i686
gpgcheck=0
enabled=1

After saving the new.repofiles, users of both platforms should issue the following command to update the local package database:

yum update

Installing Packages

Issue the following command (as root or withsudo) to install the latest stable version of MongoDB and the associated tools:

yum install mongo-10gen mongo-10gen-server

When this command completes, you have successfully installed MongoDB! Continue for configuration and start-up suggestions.

Configure MongoDB

These packages configure MongoDB using the/etc/mongod.conffile in conjunction with thecontrol script. You can find the init script at/etc/rc.d/init.d/mongod.

This MongoDB instance will store its data files in the/var/lib/mongoand its log files in/var/log/mongo, and run using themongoduser account.

Note

If you change the user that runs the MongoDB process, you will need to modify the access control rights to the/var/lib/mongoand/var/log/mongodirectories.

Control MongoDB

Start MongoDB

Start themongodprocess by issuing the following command (as root, or withsudo):

service mongod start

You can verify that themongodprocess has started successfully by checking the contents of the log file at/var/log/mongo/mongod.log.

You may optionally, ensure that MongoDB will start following a system reboot, by issuing the following command (with root privileges:)

chkconfig mongod on

Stop MongoDB

Stop themongodprocess by issuing the following command (as root, or withsudo):

service mongod stop

Restart MongoDB

You can restart themongodprocess by issuing the following command (as root, or withsudo):

service mongod restart

Follow the state of this process by watching the output in the/var/log/mongo/mongod.logfile to watch for errors or important messages from the server.

Controlmongos

As of the current release, there are nocontrol scriptsformongos.mongosis only used in sharding deployments and typically do not run on the same systems wheremongodruns. You can use themongodbscript referenced above to derive your ownmongoscontrol script.

Using MongoDB

Among the tools included in themongo-10genpackage, is themongoshell. You can connect to your MongoDB instance by issuing the following command at the system prompt:

mongo

This will connect to the database running on the localhost interface by default. At themongoprompt, issue the following two commands to insert a record in the “test”collectionof the (default) “test” database and then retrieve that document.

> db.test.save( { a: 1 } )
> db.test.find()
