mongodb service is not starting up

Question

I've installed the mongodb 2.0.3, using the mongodb-10gen debian package. Everything went well, except the service which is installed by default is not starting up when computer starts. The mongod is running only as root user. maybe this is the reason. but as far as I know, the services should be running since they are added by the root user.

What may be the solution?

if I run just mongod

Tue Mar 27 13:00:44 [initandlisten] couldn't open /data/db/transaction_processor_dummy_development.ns errno:1 Operation not permitted

If I run sudo service mongodb start it says:

mongodb start/running, process 4861

but there's no process when looking with htop and mongo says:

MongoDB shell version: 2.0.3
connecting to: test
Tue Mar 27 13:02:40 Error: couldn't connect to server 127.0.0.1 shell/mongo.js:84
exception: connect failed

Answer 1

On my ubuntu server, just run:

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