3. Install MongoDB
3.1 Configuring Yum Source

 /etc/yum.repos.d/mongodb.repo->
[MongoDB]
name=mongodb Repository
baseurl=http:// downloads-distro.mongodb.org/repo/redhat/os/x86_64/
gpgcheck=0
enabled=1

If it's a 32bit system,

[MongoDB]

baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/i686/
gpgcheck=0
enabled=1

3.2 Installing MongoDB version

sudo yum install mongodb-org

Install the specified version 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
3.3 To avoid the unintended escalation

 /etc/yum.conf->
 Exclude=mongodb-org,mongodb-org-server,mongodb-org-shell,mongodb-org-mongos, Mongodb-org-tools

4. Run MongoDB
Note the MongoDB default port and the status of the SELinux service.
Data file directory:/var/lib/mongo, log file directory:/var/log/mongo.
Change the/var/lib/mongo and/var/log/mongo permissions to the MongoDB runtime.
4.1 Start MongoDB

sudo service Mongod start

4.2 Confirms MongoDB started successfully
Check the MongoDB log file/var/log/mongodb/mongod.log.
Add MongoDB to boot service:

sudo chkconfig mongod on 

4.3 Off MongoDB Service

sudo service Mongod stop

4.4 Restart MongoDB Service

sudo service mongod restart

4.5 Start using MongoDB
