    1. Check the Release
    [root@mongotest ~]# cat /etc/redhat-release
    Red Hat Enterprise Linux Server release 6.7 (Santiago)

    2. Check the platrom, Here in my case it is 64 bit.
    [root@mongotest ~]# uname -ix86_64

    3. Create Repo for mongoDB 3.x.
    [root@mongotest ~]# vi /etc/yum.repos.d/mongodb-org-3.0.repo
    name=MongoDB Repositorybaseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.0/x86_64/gpgcheck=0enabled=1
    [root@mongotest ~]#

    [root@mongotest ~]# yum install -y mongodb-org

    5. Check SELinux status. If not disabled,  disable it or  accept the communication  at port 27017. In my case i've disabled SELinux.
    semanage port -a -t mongod_port_t -p tcp 27017
    [root@mongotest ~]# sestatus
    SELinux status:                 disabled
    [root@mongotest ~]#

    6. Before starting mongoDB, change the DB server IP. Otherwise it'll bind to loopback address.
    [root@mongotest ~]# vi /etc/mongod.conf
    [root@mongotest ~]# grep -i bind /etc/mongod.conf
    #  bindIp:  
    # Listen to local interface only, comment to listen on all interfaces.  

    7. Strat the Service.
    service mongod start

    8. Make it Persistent.
     chkconfig mongod on

    9. Check the Logs
