Install the MongoDB 2.6 tutorial using yum on the CentOS 6.5 system

Let's install the latest version of MongoDB 2.6.0 on CentOS 6.5 x64.

MongoDB v2.4.x version of the software warehouse has two packages:

1) mongo - 10 gen - server
This package contains the latest versions of the mongod and mongos daemons as well as the associated configuration and initialization scripts.

2) mongo - 10 gen
This package contains the latest version of all the MongoDB tools. These tools allow you to manage your MongoDB system.

However, there are 5 packages in MongoDB v2.6.0 software warehouse 1:

1) mongodb - org
This package is a meta-package that automatically installs the following four component packages.
2) mongodb org -- server
This package contains the mongod daemon, along with the associated configuration and initialization scripts.
3) mongodb org -- mongos
This package contains the mongos daemon.
4) mongodb org -- shell
This package contains the mongo shell environment.
5) mongodb org -- tools
This package contains the following MongoDB tools: mongoimport, bsondump, mongodump, mongoexport, mongofiles, mongoimport, mongooplog, mongoperf, mongorestore, mongostat, and mongotop.

Control script: mongodb - org package there are all kinds of control script, including the initialization scripts/etc/rc d/init d/mongod
Configure MongoDB using the /etc/ mongod.conf configuration file.

MongoDB 2.6.0 no longer has the mongos control script. The mongos process is only used for sharding scenarios. You can use the mongod initialization script to drive the mongos control script.

To install the latest 64-bit MongoDB version 2.6.0, follow these steps:

1. Create mongodb.repo

In/etc yum. repos. d/directory to create file mongodb repo, it contains MongoDB configuration information of the warehouse, the content is as follows:

[mongodb]

name=MongoDB Repository

baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64/

gpgcheck=0

enabled=1
2 Execute the installation command 

$ sudo yum install mongodb-org
