Generic init script for Fantom based server processes
This is a generic Linux init script for Fantom server processes.
It doesn't use start-stop-daemon so it should work on any Linux distro (tested on Debian and Centos)
It's meant to to be generic and easily configurable.
Basically you would probably want to do this:
- Create a "fantom" user that we will use to run the server since it's best not to run it as root. (even safer is to have /bin/false set as the shell for the fantom user.
ie:
sudo adduser fantom --home /home/fantom --shell /bin/false --disabled-password
- Download & copy this script in /etc/init.d .
ie:
cp initscript.sh /etc/init.d/mycoolserver && chmod +x /etc/init.d/mycoolserver
- Edit the first few lines of the script and adjust the variables as needed.
ie: replace "mycoolserver" and set FANTOM_HME and FAN_ARGS according to your project and pod names.
You can test it using
/etc/init.d/mycoolserver start .. same with stop
The you can make it start automatically at boot (debian)
update-rc.d mycoolserver defaults or (redhat)
chkconfig --add mycoolserver
