Question

this is the error:

Answer 1

On Mac OSX Yosemite after standard install with brew:

sudo chown -R `id -u` /data/db

if it not starts (check if there are no hanging and blocking connections):

lsof -i:27017

outputs something like:

COMMAND   PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
mongod  16948 andi    8u  IPv4 0x883a71bc9412939d      0t0  TCP *:27017 (LISTEN)

take value of PID and run:

kill -9 

now you should be able to start mongo server: mongod and then e.g in separate console window connect to it with mongo
