sudo service mongodb restart gives "unrecognized service error" in ubuntu 14.0.4

I just installed mongoDB on ubuntu 14.0.4. I tried to start the shell but I'm getting a connection refused error.

me@medev:/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 127.0.0.1:27017, reason: errno:111 Connection refused
2014-11-10T15:06:28.085-0500 Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146
exception: connect failed

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

me@medev:/etc/init.d$ sudo service mongodb restart
mongodb: unrecognized service
me@medev:/etc/init.d$ 

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

what i've tried so far:

I found another post here: can't start mongodb as sudo which made a comment about remove the mongo lock file.

I deleted the lock file and then retried my command but it still fails as you can see below:

me@medev:/var/lib/mongodb$ sudo rm mongod.lock 
me@medev:/var/lib/mongodb$ ls
journal  local.0  local.ns  _tmp

me@medev:/var/lib/mongodb$ sudo service mongodb start
mongodb: unrecognized service

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

me@medev:/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
me@medev:/var/lib/mongodb$ ls
journal  local.0  local.ns  mongod.lock

me@medev:/var/lib/mongodb$ mongo
MongoDB shell version: 2.6.5
connecting to: test
> db
test
> 

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

Solution 1:

Try this:

Write mongodb instead of mongod

sudo service mongodb status

Solution 2:

I got the same error one day You should use this:

1.Get the status of your mongo service:

 /etc/init.d/mongod status

or

 sudo service mongod status

2.If it's not started repair it like this:

sudo rm /var/lib/mongodb/mongod.lock
mongod --repair
sudo service mongodb start

And check again if the service is started again(1)
