I've tried this on CentOS 7 and 8 and I'm getting the same result. Also tried with different versions of MongoDB. I'm trying to run a Pritunl VPN on a hyper-v VM and have followed this tutorial for installing mongodb and this tutorial for setting everything up with the exception that I'm using a VM rather than a VPS.
When I run "systemctl start mongod" I get the error "Job for mongod.service failed because a fatal signal was delivered causing the control process to dump core. See "systemctl status mongod.service" and "journalctl -xe" for details."
Running journalctl -xe yields something along the lines of the code included below. I tried disabling core dump and the "Process" number changed from 3397 to 4143. Also included the output of systemctl status mongod.service.
This is my first time working with something like this so there's a high possibility I'm missing something simple. I keep seeing mention of directory files in some of the solution posts but according to the mongodb install instructions it should create it's own directories. Any help is appreciated because I am beyond lost.
journalctl -xe:
