I am not able to find any useful answer for my problem yet.but the mongod starts successfully by running as root user from cmd

sudo mongod -f mongod1.conf

Solution

  • found the answer after a couple of time..

    You must configure SELinux to allow MongoDB to start on Red Hat Linux-based systems (Red Hat Enterprise Linux or CentOS Linux).

    The permission issue is solved by making access to the relevant ports (e.g. 27017) for SELinux if in enforcing mode. See Default MongoDB Port for more information on MongoDB’s default ports. For default settings, this can be accomplished by running

    semanage port -a -t mongod_port_t -p tcp 27025
