I built and installed sphinx search on my ubuntu 9.04 server.
How do I make the sphinx daemon start automatically when I reboot?

I don't know Sphinx, but here's the basic approach. Create a file /etc/init.d/searchd with the following contents (there's also this script, but you'll probably need to adjust it a bit):
#!/bin/bash
case "${1:-''}" in
'start')
# put the command to start sphinx
# i.e., /usr/bin/searchd start or /usr/bin/searchd --daemon or whatever the command is
;;
'stop')
# stop command here
;;
'restart')
# restart command here
;;
*)
echo "Usage: $SELF start|stop|restart"
exit 1
;;
esac
Then execute the following:
$ sudo update-rc.d searchd defaults
To control the service manually:
$ sudo /etc/init.d/searchd <start|stop|restart>

This script worked perfectly. For the record, here are the start/stop/restart commands that I used. This is on an Ubuntu Hardy server, and I installed sphinx 0.9.8.1-release from source. start /usr/local/bin/searchd stop /usr/local/bin/searchd --stop restart /usr/local/bin/searchd --stop && /usr/local/bin/searchd– AprecheAug 9, 2009 at 12:34

Worked like a charm. One word of caution: make sure the searchd file has the proper permissions.– DavidOct 8, 2012 at 2:52
We deployed Sphinx for a customer on Debian systems, and used Runit to manage the processes. We didn't have to write a special init script, and since we were using Runit on other platforms (CentOS/RHEL mainly) it was perfectly portable.
The version of sphinx that is packaged for ubuntu at time of writing (0.99) has the startup script below.
I re-used it for the 2.0.1 beta which I compiled from source, just changing the line DAEMON=/usr/local/.. and it works for me.

I don't really know sphinx, but judging by the online manual, you need to have a startup script to run the daemon. Typically this is done by creating an entry in /etc/init.d and linking it into the appropriate /etc/rcX.d directory. Check the README file in /etc/init.d for details.
If nothing else, something like this is the quick and dirty answer:
$ cat > /etc/init.d/sphinx
cd /usr/local/sphinx/etc
/usr/local/sphinx/bin/searchd
^D
$ ln -s /etc/init.d/sphinx /etc/init.d/rc3.d/S99sphinx
Create a short script file (bash, perhaps) that has the equivalent of the following line in it:
/path/to/sphinx/installation/searchd --config /path/to/sphinx/config/sphinx.conf &
Then move the script to /etc/init.d as root, and chmod the script ("chmod +x myscript.sh")
I would suggest an even simpler solution:
Just add /usr/bin/searchd to /etc/rc.local before the line that says exit 0
If you happen to use sphinx in your rails application is a dead easy way to manage this with the whenever gem.
Ryan Bates made a very good screencast about it. This site won't let me put more than one link here but I recommend it.
Take a look at this forum post: http://sphinxsearch.com/forum/view.html?id=3568#18044
Basically you can add a cron job that will start Sphinx on reboot by executing this from the command line:
crontab -e
Then add the following:
@reboot searchd --config /path/to/config.conf
