Unable to connect to MongoDB

Question

I've just installed MongoDB (standard Ubuntu build, not the latest stable) and for some reason I can't connect:

Mon Feb  6 03:11:22 Error: couldn't connect to server 127.0.0.1 shell/mongo.js:79
exception: connect failed

Now my machine isn't 127.x.x.1 it's for some reason x.x.x.2 (But i've changed my config to bind to that address, and also tried to bind to my public IP which provided no avail.

Config:

#mongodb.conf

# Where to store the data.

# Note: if you run mongodb as a non-root user (recommended) you may
# need to create and set permissions for this directory manually,
# e.g., if the parent directory isn't mutable by the mongodb user.
dbpath=/var/lib/mongodb

#where to log
logpath=/var/log/mongodb/mongodb.log

logappend=true

bind_ip = 199.21.114.XX
port = 27017

I've checked the logs and only startup info is displaying in there.

I've also checked that the deamon is running too, and it is - I even tried running it manually with a --fork.

Has anyone come across this before? Or any suggestions?

Thx

UPDATE:

After a restart - here are the logs:

Answer 1

I solved this problem by commenting out the following line in my /etc/mongod.conf file.

# Listen to local interface only. Comment out to listen on all interfaces. 
#bind_ip = 127.0.0.1

You will need to follow this config change with restarting the mongod process.

sudo service mongod restart

Answer 2

By default, running the mongo console command will look for mongodb on your localhost, hence the 127.0.0.1 IP which is your local loopback. Also, the default config for mongod should be available on localhost. Its better to do it this way for now to start, unless you have turned on auth. Make sure you have auth enabled or your database is running openly on your public ip.

When you want to connect to a host other than localhost or your default config, you do:

mongo <host>
