I am a total mongo newbie who is very confused, frustrated and frankly lost...
I have tried installing / uninstalling mongo, then reinstalling. AT one point it seemed to be working as I followed a tutorial but ultimately wouldn't after I returned to use it in a node app I am trying to create. Now that I have it installed I created the /data/db but it keeps failing when I go to run "mongod"

If it is the first time you are running MongoDB, make sure you have you have owner permission to create mongod.lock file to create in /data/db path.
sudo chown -R `id -u` /data/db
first try:
mongo localhost
to see if there already a mongod instance running. if not, you should delete the mongod.lock
sudo rm /data/db/mongod.lock
if means you had an unclear shutdown of mongod.
Important: this assumes you don't have anything important in the DB because it seems it's running on your macbook air.
I have installed MongoDB on Mac OSX. When I do mongod it does not start any connections; instead it displays the output below. Can someone please help me to resolve this

I had this problem. I solved it by increasing the memory size for the replica using Virtual Box.
Am new to mongodb. I have installed it on my pc with wamp server and it is working fine. Now am trying to connect with EC2 remotely.
I have gone through this . But still am not getting to connect.

Starting mongod: [FAILED]
How to solve this ?
By installing all these from This was solved my problem.
The error says that the address is already in use. Are you sure it's not already running?
Because of the size of the mongodb database I'm trying to build and because I needed a filesystem that can handle parallel writes, I moved it on a cluster that has lustreFS, which fulfills these needs.
The problem is that I can't start mongod, so I can't connect anything to the database, because mongod can't get a lock on mongod.lock. I don't have root or sudo permissions but this does not seem to be the problem here because permissions are not mentioned, as you can see:

Could you please tell me if there's any way around that lock? And no, there weren't any other mongod instances running.
Solution: File locking was being disabled by cluster admins. After file locking was enabled, mongod started and accepted connections as it should.

#monkeyUser,
Running two different MongoDB instances is not an issue per-se provided they use different data directories. In your case, looks like you have two MongoDB installation with same data directory configured for both. If you intend to keep both the instances you'll need to change the dbPath for one of them to point at some other directory.
If you do not intend to run two instances and only the latest instance, uninstall the previously installed instance using same steps from the blog post but executing them in reverse order (bottom up) and in inverted sense i.e. if blog has a step to create a directory /data/db, you would execute this steps as "deleting the data directory /data/db". Once you have removed one of the instances, second instances should come up fine.
