MongoDB: ERROR: child process failed, exited with error number 14

Question

I run MongoDB on Mac:

Shave:mongodb_simple Logan$ ./bin/mongod -f conf/mongod.conf
about to fork child process, waiting until server is ready for connections         


        

Answer 1

In my mongodb setup, in order to retain a specific version of mongoDB inline to existing servers and also to avoid having binary files placed under root disk, i changed the path of all mongo binaries in a different directory. i had to use rpm option instead of yum option (as yum installs only the latest version despite of mentioning the specific version).

rpm -ivh --prefix=/apps/mongodb /apps/mongo_rpm_packages/mongodb-org-*.rpm 

Note: The default path where the binaries will be placed is /var/lib/mongo.

This approach does not either allow required permission for mongod user or its not provisioned properly and hence, i changed user and group in mongod.service file to root user and managed to successful start the process using:

service start mongod
