 I just installed mongoDB on my ubuntu 14.0.4 operating system. I tried to start the shell but I'm getting a connection refused error. Please refer the following code:

[email protected]:/etc/init.d$ mongo

MongoDB shell version: 2.6.5

connecting to: test

2014-11-10T15:06:28.084-0500 warning: Failed to connect to, reason: errno:111 Connection refused

2014-11-10T15:06:28.085-0500 Error: couldn't connect to server (, connection attempt failed at src/mongo/shell/mongo.js:146

exception: connect failed

So I restart the service but that's failing too. I get the following error message:

[email protected]:/etc/init.d$ sudo service mongodb restart

mongodb: unrecognized service

[email protected]:/etc/init.d$ 

This is what I have in my /var/log/mongodb/mongod.log - http://pastebin.com/MrHt8tce

I have also deleted the lock file and then re-run the command but it still fails as you can see below:

[email protected]:/var/lib/mongodb$ sudo rm mongod.lock 

[email protected]:/var/lib/mongodb$ ls

journal  local.0 local.ns  _tmp

[email protected]:/var/lib/mongodb$ sudo service mongodb start

mongodb: unrecognized service

But I can start it using /etc/init.d as you can see below:

[email protected]:/var/lib/mongodb$ sudo /etc/init.d/mongod start

Rather than invoking init scripts through /etc/init.d, use the service(8)

utility, e.g. service mongod start

Since the script you are attempting to invoke has been converted to an

Upstart job, you may also use the start(8) utility, e.g. start mongod

mongod start/running, process 27469

[email protected]:/var/lib/mongodb$ ls

journal local.0  local.ns mongod.lock

[email protected]:/var/lib/mongodb$ mongo

MongoDB shell version: 2.6.5

connecting to: test

> db


Any ideas on why I can't start it using the service command would be appreciated. From what I've read, i should be using sudo service mongodb

In your case what you can do first check the status of your MongoDB service:

/etc/init.d/mongod status


sudo service mongod status

If the service doesn’t get started, in that case, replace the following code:

>service mongod start

With this:

>start mongod
