4.4 is not general availability. Basically be aware you are not running a currently supported configuration.

While the 4.4 release candidates are available, these versions of MongoDB are for testing purposes only and not for production use .

For new features in MongoDB 4.4, see Release Notes for MongoDB 4.4 (Release Candidate).

The official packages come with integrations for the appropriate init system(systemd, system v init). Negating the need to execute mongod manually.

You are effectively running this mongod as root, not a good practice, and you may run into file/directory permissions later if you transition to using it the ‘regular’ way.

Although you have the installation guide you have not diligently applied it’s guidance and wisdom, luck be with you.
