mongodb connection issue: `connect’: Failed to connect to a master node at localhost:27017 (Mongo::ConnectionFailure)

You just try to start the mongodb by

service mongod start

or

start mongod

And check mongodb process is running by checking

ps aux | grep mongo

You can see the status by

service mongod status

If it is not starting then try to remove the mongod lock file by,

rm /var/lib/mongodb/mongod.lock

Then start the mongodb server again.
