sudo systemctl mongod restart terminates mongod and it will not start again

Question

I installed mongodb on my ubuntu 16.04 machine on aws using these instructions with a slight deviation: I ran the mongod process with sudo systemctl mongod start as from what I have read, that works better with Ubuntu 16.04. I fiddled around a little, created a user, added

security: authentication: 'enabled'

edit:

security: authorization: 'enabled'

/edit

(with 2 spaces, 4 spaces, and a tab iteratively) to /etc/mongod.conf and went to restart with

sudo systemctl mongod restart

but now checking with netstat -tupln , mongod is not running. I also tried restarting with sudo systemctl mongod start but that's not working either. Any guidance would be appreciated.

Answer 1

The config key is not correct. It's authorization, not authentication

security: 
    authorization: enabled

See https://docs.mongodb.com/v3.4/reference/configuration-options/#security-options

Answer 2

you said sudo systemctl mongod start and then sudo systemctl restart mongod - look at the position of start and restart, you're using systemctl incorrectly.

you can use also use systemctl status mongod

also check upstart or syslog in /var/log/ , you should find an error there explaining why the service didn't start.
