Question

I'm testing learning locker which is based on MongoDB it's all inside a ubuntu14.04 docker https://hub.docker.com/r/hadyrashwan/learninglocker-ubuntu14.04/ . I got it to work but I can't start Mongodb automatically tried the repair command and changing the name in start service command to Mongodb or mongo but not working. but running Mongodb just make it start but I want to start it automatically not opening a terminal and leave it open so the system continues to work

you need to install mongo as a service. check this out docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu – Melano

@DeendayalGarg adding a service is listed for 16.04 which got systemd If I understand correctly . I used 14.04 to avoid php 7 and downgrading it – Ern

systemd is required when u r using ubuntu 16 . but installing mongo as a service is required if you are using command sudo service mongod start in any ubuntu version. check this for more info. digitalocean.com/community/tutorials/… – Melano

I couldn't get it to work I need to reinstall mongo . I will try reinstalling it all together also work with 16.04 for systemd – Ern

Answer 1

If already you install the mongodb just uninstall based on mongodb config

Before going do all stuff first install mongodb server.

sudo apt install mongodb-server  

Then continue to install what mongodb config suggest you.

Once done your mongodb configuration you can go

sudo service mongodb start

Note: Its not mongod its mongodb

Answer 2

I had same problem. It seems there is some mis-configuration if you install via source code.

Re-installing mongoDB using apt-get activated mongod as a service for me.

how do you do that? – Brannen
