MongoDB won't start

[Trung_Le_Dinh (Trung Lê đình)]

I can’t start mongodb. Here are some log and config files that I could trace.
Any help would be much appriciated. Thanks.

14 Returned by MongoDB applications which encounter an unrecoverable error, an uncaught exception or uncaught signal. The system exits without performing a clean shutdown.

You’ll have more helpful output in journalctl journalctl -xe (as per the output from systemctl start/restart) or journalctl -u mongod possibly even in /var/log/mongo/mongod.log

@chris

even in /var/log/mongo/mongod.log

This is definitely the first place I would check.
