This question already has an answer here:

• mongodb Mongod complains that there is no /data/db folder 16 answers

When I try to run Mongod in terminal I got this message :

2015-05-14T17:33:04.554+0700 I STORAGE  [initandlisten] exception in initAndListen: 29 Data directory /data/db not found., terminating 2015-05-14T17:33:04.554+0700 I CONTROL  [initandlisten] dbexit:  rc: 100 

and running mongo command :

MongoDB shell version: 3.0.3 connecting to: test 2015-05-14T17:34:26.679+0700 W NETWORK  Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused 2015-05-14T17:34:26.681+0700 E QUERY    Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed     at connect (src/mongo/shell/mongo.js:179:14)     at (connect):1:6 at src/mongo/shell/mongo.js:179 exception: connect failed 

I Have tried to change permision in /var/lib/mongodb and /var/log/mongodb, but still doesnt work, and I tried to uninstall and install mongodb again, but still the same problem exist. Anyone could help? Thanks

I'm using Ubuntu 14.04 LTS 64 bit

MongoDB needs data directory to store data. Default path is /data/db

When you start MongoDB engine, it searches this directory which is missing in your case. Solution is create this directory and assign rwx permission to user.

If you want to change the path of your data directory then you should specify it while starting mongod server like,

mongod --dbpath /data/ --port 

This should help you start your mongod server with custom path and port.
