I have an issue where I cannot connect to the MongoDB server using the cmd mongod after downloading MongoDB.
this is what the terminal shows when using mongod:
$ mongod

I've tried uninstalling/purging and reinstalling MongoDB numerous times. I am able to connect after the following...
un-installing MongoDB...
sudo service mongod stop
sudo apt-get purge mongodb-org*
sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongodb
sudo apt-get purge mongodb mongodb-clients mongodb-server mongodb-dev
sudo apt-get purge mongodb-10gen
sudo apt-get autoremove
un-installing Compass...
sudo dpkg --remove mongodb-compass
I then go to the MongoDB documentation to install:
"MongodDB Community Edition for Ubuntu",
specifically 20.0.04 LTS ("Focal")
... which I have
nick@777:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.3 LTS
Release: 20.04
Codename: focal
I do the following from the documentation...
wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add -
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list
sudo apt-get update
sudo apt-get install -y mongodb-org

verify the mongod version using mongod --version

I also get this Output when checking the status with sudo systemctl status mongod
sudo systemctl status mongod
● mongod.service - MongoDB Database Server

Nov 29 20:24:04 Lufarius777 systemd[1]: mongod.service: Failed with result 'exit-code'.
I honestly don't know if the terminal is showing the correct output for the command mongod
I've also tried stopping/restarting the service with the following
sudo systemctl stop mongod
sudo systemctl restart mongod
any Help would be SUPER helpful to put this nightmare to an end, thank you!
