This chapter is intended for sysadmins being tasked to install an instance of OpenWFE on a system.
A linux system usually places its services' start scripts in /etc/rc.d/ or /etc/init.d/. Here is an example of a start script for a Debian system. (OpenWFE is developed on Debian GNU/Linux).
Figure 4.1. OpenWFE Debian start script
#! /bin/sh
set -e
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
#
# may be necessary
#
#export JAVA_HOME=/usr/local/java
#OWFE_USER=toto
#OWFE_GROUP=toto
OWFE=/usr/local/owfe-suite.sh
NAME=openwfe
DESC="OpenWFE - Open source WorkFlow Engine"
SCRIPTNAME=/etc/init.d/$NAME
# Gracefully exit if the package has been removed.
test -x $DAEMON || exit 0
case "$1" in
start)
echo "Starting $DESC: $NAME."
#start-stop-daemon --start --quiet --chuid $OWFE_USER:$OWFE_GROUP --exec $OWFE
start-stop-daemon --start --quiet --exec $OWFE
;;
stop)
echo "Stopping $DESC: $NAME."
$OWFE stop
;;
*)
# echo "Usage: $SCRIPTNAME {start|stop}" >&2
echo "Usage: $SCRIPTNAME {start|stop}" >&2
exit 1
;;
esac
exit 0
You can see that in this example, OpenWFE has been deployed in /usr/local/openwfe and is run as the root user.
This script located at /etc/init.d/openwfe can then be chmod a+x /etc/init.d/openwfe and added to the services started at boot time with update-rc.d openwfe defaults.
The service can then be manually started or stopped with /etc/init.d/openwfe start or invoke-rc.d openwfe start
