I've installed mongodb using homebrew. The mongo command runs as expected in terminal but when I run mongod in terminal it returns this:
mongod --help for help and startup options

So I can't use mongo class in my php application. Is it caused by some port confliction? Is there any solution to this?
If you see the Exception, it says:
exception in initAndListen:
10309 Unable to create/open lock file: /data/db/mongod.lock
errno:13 Permission denied Is a mongod instance already running?, terminating
Either mongod instance could not create the lock file or a lock file is already present in the location, and the current instance cannot get hold of it, due to improper termination/shutdown of a previously run mongod instance.
To solve this, manually delete the /data/db/mongod.lock, if it is present and restart the mongod service.
sudo rm /data/db/mongod.lock
In case the lock file is not present, give read/write permissions of the /data/db directory and restart the instance.
