Installing Mongo in Linux using yum

Installing Mongo in linux using yum.

The Mongo DB downloads repository contains two packages:

• mongo-10gen-server

This package contains the mongod and mongos daemons from the latest stable release and associated configuration and init scripts. Additionally, you can use this package to install daemons from a previous release of MongoDB.

• mongo-10gen

This package contains all MongoDB tools from the latest stable release. Additionally, you can use this package to install tools from a previous release of MongoDB. Install this package on all production MongoDB hosts and optionally on other systems from which you may need to administer MongoDB systems.

Install MongoDB

Configure Package Management System (YUM)

Create a /etc/yum.repos.d/mongodb.repo file to hold the following configuration information for the MongoDB repository:

TIP

For production deployments, always run MongoDB on 64-bit systems.

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 Packages

Issue the following command (as root or with sudo) 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!

Manage Installed Versions

You can use the mongo-10gen and mongo-10gen-server packages to install previous releases of MongoDB. To install a specific release, append the version number, as in the following example:

yum install mongo-10gen-2.2.3 mongo-10gen-server-2.2.3

This installs the mongo-10gen and mongo-10gen-server packages with the 2.2.3 release. You can specify any available version of MongoDB; however yum will upgrade the mongo-10gen and mongo-10gen-server packages when a newer version becomes available. Use the following pinningprocedure to prevent unintended upgrades.

To pin a package, add the following line to your /etc/yum.conf file:

exclude=mongo-10gen,mongo-10gen-server
