INSTALL MONGODB ON RHEL AND CENTOS

STEP 1:- 

          Configure Package Management System (YUM)

Create a /etc/yum.repos.d/10gen.repo file 

[ nitin@nitin-ubuntu: ~ ] $ sudo vim /etc/yum.repos.d/10gen.repo

[10gen]
name=10gen Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64
gpgcheck=0
enabled=1

[ nitin@nitin-ubuntu: ~ ] $ yum clean all

[ nitin@nitin-ubuntu: ~ ] $ sudo yum install mongo-10gen mongo-10gen-server

STEP 2:-

Configure MongoDB

These packages configure MongoDB using the /etc/mongod.conf file in conjunction with the control 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/mongo and its log files in /var/log/mongo, and run using the mongod user account.

STEP 3:- 

Start MongoDB

[ nitin@nitin-ubuntu: ~ ] $ sudo service mongod start

STEP 4:- 

Stop MongoDB

[ nitin@nitin-ubuntu: ~ ] $ sudo service mongod stop
