How to run a Harbour application as a service on a Linux Server

[nilton-medeiros]

I realized that everything in Harbour is geared to run on Windows. There is nothing here of examples of how to run an application in Harbour as an Ubuntu server service or CentOS server, without a GUI.

There are so many solutions to run something as a service. These days you'd probably like to see a systemd solution template.
Nobody contributed i guess. Other than that i highly doubt that everything in Harbour is geared to run on Windows.

There is simple posix deamon in hbunix contrib which puts app itself into the background:
https://github.com/harbour/core/blob/master/contrib/hbunix/tests/daemon.prg

You can add a line to cron using crontab -e
@reboot /path/to/app //gtnul

I hope that others will share their precious solutions. I'm not complaining that the gcc compiler does not help me in running an app as a service on Linux, maybe the others thought the same about Harbour, so we don't have anything else than posix deamon in the repository.

netio is a good example of a service that runs on win/linux. Here is what I use on Ubuntu: #! /bin/sh ### BEGIN INIT INFO # Provides: hbnetio # Required-Start: $syslog # Required-Stop: $syslog # Default-Start: 2 3 4 5 # Default-Stop: # Short-Description: Harbour NetIO server ### END INIT INFO set -e # /etc/init.d/netio: start and stop the Harbour hbnetio daemon # to install the service # copy this file (or symlink) into /etc/init.d/ # update-rc.d netio defaults # start the service with: service netio start EXE=/Sandbox/harbour/bin/linux/gcc/hbnetio CONF=/etc/hbnetio.conf PID=/run/hbnetio.pid umask 022 PORT=2941 IFACE=0.0.0.0 ROOTDIR=/srv/netiodir RPC=-rpc NOUI=-noui PASS=yoursecretpassword if test -f $CONF; then . $CONF fi OPTS="-port=$PORT -iface=$IFACE -rootdir=$ROOTDIR $RPC $NOUI -pass=$PASS" echo $OPTS . /lib/lsb/init-functions # Are we running from init? run_by_init() { ([ "$previous" ] && [ "$runlevel" ]) || [ "$runlevel" = S ] } check_privsep_dir() { # Create the PrivSep empty dir if necessary if [ ! -d /run/hbnetio ]; then mkdir /run/hbnetio chmod 0755 /run/hbnetio fi } export PATH="${PATH:+$PATH:}/usr/sbin:/sbin" case "$1" in start) check_privsep_dir log_daemon_msg "Starting Harbour NetIO server" "hbnetio" || true if start-stop-daemon -b --make-pidfile --start --quiet --oknodo --chuid 0:0 --pidfile $PID --exec $EXE -- $OPTS; then log_end_msg 0 || true else log_end_msg 1 || true fi ;; stop) log_daemon_msg "Stopping Harbour NetIO server" "hbnetio" || true if start-stop-daemon --remove-pidfile --stop --quiet --oknodo --pidfile $PID --exec $EXE; then log_end_msg 0 || true else log_end_msg 1 || true fi ;; restart) check_privsep_dir log_daemon_msg "Restarting Harbour NetIO server" "hbnetio" || true log_daemon_msg "Stopping Harbour NetIO server" "hbnetio" || true start-stop-daemon --remove-pidfile --stop --quiet --oknodo --retry 30 --pidfile $PID --exec $EXE log_daemon_msg "Starting Harbour NetIO server" "hbnetio" || true if start-stop-daemon -b --make-pidfile --start --quiet --oknodo --chuid 0:0 --pidfile $PID --exec $EXE -- $OPTS; then log_end_msg 0 || true else log_end_msg 1 || true fi ;; status) status_of_proc -p $PID $EXE hbnetio && exit 0 || exit $? ;; *) log_action_msg "Usage: /etc/init.d/ssh {start|stop|restart|status}" || true exit 1 esac exit 0

Hi @prgwiz, thank you very much for answering, I am inexperienced in Linux, I know the content above is an example and from what I understand it is a type of script, in which directory and with what name do I save it? This content points to several directories and files that I would have to look at to understand what it is doing, for example "CONF=/etc/hbnetio.conf", seems to be more complex than I expected. Someone must have a simpler example of Harbour as a service.
