db = Mongo::Connecti         


        

Answer 1

I just encountered this due to my /etc/hosts file not containing an entry for "localhost" - consequently Ruby couldn't resolve "localhost". I suppose you can hardcode 127.0.0.1 into your code rather than "localhost" - or fix /etc/hosts to contain:

127.0.0.1 localhost

Answer 2

Sometimes there is simply not enough space.

exception in initAndListen: 15926 Insufficient free space for journals, terminating

Answer 3

If you're on a Mac and used Brew, restarting the service solved it for me:

launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist

You can find this info by running brew info mongodb.

Answer 4

This is definitely due to your mongo server not running. Since you're on Ubuntu, try doing a sudo /etc/init.d/mongodb start and then see if your code works.

Answer 5

On a mac, using brew I found that brew info mongodb and then using then

ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents or mongod --config /usr/local/etc/mongod.conf worked!

Answer 6

had this happen several times now, and here is the solution that works for me:

sudo rm /var/lib/mongodb/mongod.lock
sudo -u mongodb mongod -f /etc/mongodb.conf --repair
sudo start mongodb
sudo status mongodb
