I followed this tutorial: http://howtonode.org/express-mongodb

Its strange, the first time I followed the tutorial everything worked.
But now, one day after I wanted to play with the code again I coudn’t start
the server. This is what I get:

alex@alex-System-Product-Name:~/blog2$ node app.js Express server
listening on port 3000 in development mode

node.js:134
throw e; // process.nextTick error, or ‘error’ event on first tick
^ Error: failed to connect to [localhost:27017]
at [object Object]. (/home/alex/blog2/node_modules/mongodb/lib/mongodb/connection/server.js:189:47)

at Array. (net.js:836:27)
at EventEmitter._tickCallback (node.js:126:26) alex@alex-System-Product-Name:~/blog2$

Any suggestions to fix this problem?

EDIT:

I just did:

alex@alex-System-Product-Name:~/blog2$ sudo service mongodb start
mongodb start/running, process 9847
alex@alex-System-Product-Name:~/blog2$ sudo service mongodb status
mongodb stop/waiting
alex@alex-System-Product-Name:~/blog2$

Not sure if it is running.

and this is what I get if I type $ mongo in the command line:

alex@alex-System-Product-Name:~/blog2$ mongo
MongoDB shell version: 1.8.2
