Mongodb KeyFile too open permissions

Question

I have created a three members replicaSet (in separated servers) following the tutorial on mongodb site.

I have configure in /etc/mongodb.conf the following:

fork=true

keyFile=/srv/mongodb/keyFile

And I have create the keyFile in that location and the server always told me "permissions are too open" in keyFile

What can be wrong?

Thanks in advance

Answer 1

From the docs:

The key file must not have group or “world” permissions on UNIX systems

Therefore if you run this, you should be fine (substitute actual path):

chmod 600 /path/to/keyfile

You should also make sure that the keyfile is owned by the same user that you use to run the mongod/mongos processes, otherwise setting the permissions above will cause an error (only the user that owns the file can access it with 600 permissions).
