    MongoDB doesn't start in Ubuntu

Failed to start mongod.service: Unit mongod.service not found.

Solution

$ sudo nano /etc/systemd/system/mongodb.service

[Unit]
Description=High-performance, schema-free document-oriented database
After=network.target

[Service]
User=mongodb
ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf

[Install]

Now you can start the service and check its state by
  $ sudo systemctl start mongodb

  $ sudo systemctl status mongodb


and finally enable it permanently by
  $ sudo systemctl enable mongodb


to start the daemon
 $ sudo mongod


to access the shell
  $ sudo mongo
