I just hacked the daemon cruise init script to work properly on reboot
on my debian (ubuntu) server. On debian bootup, there is a very
minimal root-user environment, so you have to do some extra steps to
make it run at all, and run as a non-root user.
The important changes are:
* shebang fully qualified to point to ruby exec
* manually populate PATH env to contain ruby (/usr/local/...)
* add cruise_user method to define local user used to run cruise
* invoke 'start' command as specified cruise_user
Here's what I currently have, hopefully it will help someone. If you
want this committed, it could use a little cleanup, and might not be
as portable as the old version - let me know if you are interested and
I can try to make a ticket/patch:
-----------------
#!/usr/local/bin/ruby
ENV['PATH']="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11"
# in order to make cruise run as daemon, you need:
# 1. cp $CCRB_HOME/daemon/cruise.sample $CCRB_HOME/daemon/cruise
# 2. specify your cruise_path to $CCRB_HOME in $CCRB_HOME/daemon/cruise file
# 3. ln -s $CCRB_HOME/daemon/cruise /etc/init.d/cruise (you may need
to 'sudo' this)
# 4. update-rc.d cruise (you may want to choose options by yourself,
and you may need to 'sudo' this)
# 5. it's done :>
