Hi Folks.
Currently I have some services running in a linux box (OpenSuse 11.2)
and they will be moved to an OpenSuse 13.2. I want to move the
services from SysV to systemd.
I noticed that in the service configuration file (namely
/usr/lin/systemd/system/MyService.service) there are some options wich
bother me a little bit. The services are programs written using
Lazarus and its service framework. Please note that the services run
either on Windows or on Linux (some $ifdef help). I wonder what
happens on two points:
1. the new service type parameter TYPE in section [Service] should be
"simple" I guess
2. the parameter TimeoutStartSec bothers me.
As in the sefvice framework developed using Lazarus units (service
project), the program is started by the INIT script in /etc/init.d
with the -r runtime switch. The program then responds to the start
event of the Daemon unit wich, in turn, starts the main thread and the
called start procedure exits as soon as posible. The program keeps
running until the exit signal is fired and the main thread is stopped.
If it is by the means of the INIT script (service MyService stop) the
process is killed either soft or hard. The question is: does a service
written in this new method still needs the Lazarus service framework ?
What is the signal sent to systemd wich informs it that the sevice has
started (read man systemd.service (5) )? The same mechanism as the
Lazarus service framework still applies ?
I'm not yet ready to use either D-BUS messaging system nor socket
based systemd start service mechanism.
Thank you for any information.
Antonio.
Hi All.
After a reading thru all documentation spread over there I succeeded to
port an Initd service to the new systemd.. Both questions above got
their answer:
1. simple is the right type
2. I didn't enven specify avy time out.
The most important lesson learned is that the service program written
using Lazarus and Fpc does not require ANY change. It woks as is
provided that the launch command includes the -r parameter.
systemctl enable MyService: OK
systemctl start MyService: OK
systemctl stop MyService: OK
Service file in /etc/systemd/system with minimal options
reboot the linux box and the service has been properly stopped and
restarted after booting again.
Nice and clear, thanks to all
Antonio.
