MongoDB manually preparing for upstart but not running

Question

I am on Ubuntu 14.04.1 LTS.

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.1 LTS
Release:    14.04
Codename:   trusty

Instead of using the system provided MongoDB which is 2.4, I want to use 2.6 so I downloaded MongoDB executable and just put it in the places I wanted. Then I mostly copied the upstart script comes with the 2.4 package:

description "MongoDB"

start on runlevel [2345]
stop on runlevel [!2345]

limit nofile 64000 64000

kill timeout 300 # wait 300s between SIGTERM and SIGKILL.

pre-start script
    mkdir -p /data/db/
end script

script
    ENABLE_MONGODB="yes"
    if [ -f /etc/default/mongodb ]; then
        . /etc/default/mongodb
    fi
    if [ "x$ENABLE_MONGODB" = "xyes" ]; then
        exec start-stop-daemon --start --quiet --chuid mongodb \
            --exec /usr/local/bin/mongod -- --config /etc/mongodb.conf
    fi
end script

When I run manually like so:

sudo /usr/local/bin/mongod --config /etc/mongodb.conf

It runs just fine.

But when I use sudo start mongodb the process probably dies out as I was not able to see it in ps -ef. The upstart log doesn't say much (/var/log/upstart/mongodb.log):

warning: bind_ip of 0.0.0.0 is unnecessary; listens on all ips by default

What may be the problem?

You say you did this:

That’s really not the supported and recommended way you should be installing MongoDB on your system. The MongoDB team is very well aware that official Linux repositories don’t always keep up to date with latest releases of many packages, so they provide their own PPA for MongoDB as explained here. I would recommend removing whatever you just installed and follow these steps instead.

First, import the public key used by the package management system:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10

Then create a sources list file for MongoDB:

echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list

Now run apt-get with update to refresh the sources list:

sudo apt-get update

And finally, install MongoDB directly from the repository like this:

sudo apt-get install -y mongodb-org
