Process Management – How to Check Running Processes and Owners

process

I want to change the mongodb database directory. Some says that I need to change the owner of the new directory to the username that is running mongodb

How do I know which user is running the mongodb service?

Well I suppose I just look at all the processes and see who own those processes.

How do I see the running processes.

I run the answer and get this. Looks like the user is mongodb. Not ubuntu, not root, but mongodb

root@ip-10-138-30-205:/media/newdrive# ps aux | grep mongodb
mongodb  17140  0.3  5.2 131484 31832 ?        Ssl  11:35   0:00 /usr/bin/mongod --config /etc/mongodb.conf                                                                                                                      
root     17154  0.0  0.1   8096   936 pts/0    S+   11:38   0:00 grep --color=auto mongodb

Use ps aux | grep mongodb. It returns the processes running in the computer whose name contains mongodb. Search for the mongodb process in that list. The first column has the user who runs the process.
