When I run "/usr/bin/mongod --config /var/data/rs1/rs1db0v3.conf". It failes. The error is:

> warning: bind_ip of 0.0.0.0 is unnecessary; listens on all ips by default
about to fork child process, waiting until server is ready for connections.
forked process: 16970
ERROR: child process failed, exited with error number 1

The permission of the relative files and folds are following:

I have no idea how to run mongod as mongodb, so I changed the ownership to user1, and then run mongod as user1. It works.
