Because of the process of killing directly, I do not know why options:{} is empty when the service is restarted. Specify the-dbpath parameter while starting

" /var/lib/mongodb/ "

However, this must ensure that the service window cannot be closed.

Start with a configuration file

Mongod-f/etc/mongod.conf

This must also ensure that the service window cannot be closed.

Start with daemon mode: Daemon

The –fork parameter allows MongoDB services to be run in the background
