My server running on Nginx Ubuntu 16.04 LTS. I want to install mongoDB to use it with node.js then I followed this tutorial but when I write the status command I have this.
● mongodb.service - High-performance, schema-free document-oriented database Loaded: loaded (/etc/systemd/system/mongodb.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Tue 2016-07-26 20:21:15 CEST; 7s ago Process: 4527 ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf (code=exited, status=14) Main PID: 4527 (code=exited, status=14) Jul 26 20:21:15 ns3039456.ip-94-23-252.eu systemd[1]: Started High-performance, schema-free document-oriented d Jul 26 20:21:15 ns3039456.ip-94-23-252.eu systemd[1]: mongodb.service: Main process exited, code=exited, status Jul 26 20:21:15 ns3039456.ip-94-23-252.eu systemd[1]: mongodb.service: Unit entered failed state. Jul 26 20:21:15 ns3039456.ip-94-23-252.eu systemd[1]: mongodb.service: Failed with result 'exit-code'.  Do you have any solution to fix my problem ? If you have a solution who need to completly remove mongodb it's ok. I have nothing in my database because this is my first installation.
I tried this command to remove mongodb :
sudo apt-get remove mongodb* --purge  But I have this error
E: Unable to locate package mongodb.service E: Couldn't find any package by glob 'mongodb.service' E: Couldn't find any package by regex 'mongodb.service'  But I did like as the tutorial said. I created the mongo.service files inside /etc/systemd/system
Edit :
With the mongod command I have this :
