The following instructions are one way to get your HAppS application to start up automatially when the machine is booted.
+Or what if the HAppS process just dies for +mysterious reasons? hunk ./templates/start-happs-on-boot.st 8 -
cp /etc/init.d/ssh /etc/init.d/happs-app
- -edit that to do the right thing with Main.exe executable.
- -install it into the linux init with
- -sudo update-rc.d happs-app multiuser
- -this is all - - -
These instructions are valid (at least) for debian/ubuntu, loosely following instructions at the debian policy manual.
+The way I deal with this both these issues with a public-facing happs application is to have a cron job that runs every minute, that will start the happs application if it isn't running.
