I've just installed MongoDB on a fresh Ubuntu 10.10 installation, but I'm having trouble getting it to start (at all). I'm using the latest mongo-stable package via. http://www.mongodb.org/display/DOCS/Ubuntu+and+Debian+packages.
I would expect it to start automatically on boot, however trying to start it manually always gives me the following:
$ sudo start mongodb
mongodb start/running, process 2565
$ sudo status mongodb
mongodb stop/waiting
ps -aux doesn't show anything mongo related. Trying to run the shell gives me:
MongoDB shell version: 1.6.3
connecting to: test
Tue Oct 12 22:33:14 Error: couldn't connect to server 127.0.0.1 (anon):1137
exception: connect failed
both /var/log/mongodb and /var/lib/mongodb exist and were presumably created by the installer. Both are owned by the mongodb user (again setup by the installer), but both are empty, so there's no mongo log file for me to check, or .lock file for me to remove.
In case it's permissions related, both are
drwxr-xr-x 2 mongodb mongodb 4096 2010-10-12 22:08 mongodb
There are no related log entries in /var/log/messages or syslog. I've tried reinstalling the package, just in case, but no difference. The version I'm running is listed as 20100930.
It's probably something simple, but I'm out of ideas, and with no errors or feedback whatsoever it's hard to know where the problem might lie. Any help appreciated.

If you haven't done so, create a data directory as described at http://www.mongodb.org/display/DOCS/Quickstart+Unix
Check the contents of /etc/mongodb.conf
I would try running the mongodb executable directly and pass it command line options
and anything else that seems useful from http://www.mongodb.org/display/DOCS/Command+Line+Parameters
