Hi,
how can I stop/restart the Servoy App server by Terminal?
I couldn’t find any function in the wiki.
Regards,
On Linux you have to create a init.d script for that, on MacOS you can use Lingon.
Which platform are you using?
Hi Nicola,
I would like to have it for both, Mac OS X and Linux.
Does the init.d script for Linux than work like: ```
./etc/init.d/servoy_server start/stop/restart
A script example would be very appreciate.
Regards,Here’s the init.d script for Ubuntu/Debian, you just need to define the USER and HOME variables in the beginning of the script and install it for the desired runlevels:
#! /bin/sh

For MacOS download Lingon, it’s pretty straight forward.
Cool! Thank you very much Nicola!
Hi Nicola,
I have created the script file “servoy” in the directory /etc/init.d on my Debian 6 system like your example.
I also defined the variables USER and HOME and set the permissions to executable, but it doesn’t work.
If I make a restart of the Server, Servoy App Server doesn’t start by init.d (note: The PostgreSQL Server is starting/stopping/restarting by its init.d script). In the logfiles I couldn’t find anything about.
Do you have any idea what could be wrong?
Regards,
Did you run the “update-rc.d” command to install the script in the desired runlevels? Check update-rc.d man page for details.
If that doesn’t fix it let me know which error you get when you run sudo /etc/init.d/servoy start.
I have tied to install the script into the runlevels by “update-rc.d” and I get:
administrator@debian-6-server:/etc/init.d$ sudo update-rc.d servoy defaults
[sudo] password for administrator:
update-rc.d: using dependency based boot sequencing
update-rc.d: warning: servoy start runlevel arguments (2 3 4 5) do not match LSB Default-Start values ( 2 3 4 5)
update-rc.d: warning: servoy stop runlevel arguments (0 1 6) do not match LSB Default-Stop values ( S 0 1 6)
insserv: Script servoy is broken: incomplete LSB comment.
insserv: missing valid name for `Provides:' please add.
I can set the startup item to enabled with “rcconf”. But this is what I get in the Terminal if I try to start the Servoy server:
administrator@debian-6-server:~$ sudo /etc/init.d/servoy start
/etc/init.d/servoy: 71: Syntax error: Unterminated quoted string
And if I check if the startup item is installed by “sudo ls -l /etc/rc?.d/servoy” I get that it is not found.
It works in Ubuntu just fine, probably your Debian expects a slightly different syntax when installing.
Just change the following lines (6 and 7) with the runlevels that update-rc.d expects:
# Default-Start: 2 3 4 5
# Default-Stop: S 0 1 6
I checked line 71 and it’s just a plain comment:
# Many daemons don't delete their pidfiles when they exit.
I checked around that line and I don’t see any “Unterminated quoted string”, Can you double check the code? Maybe some quotes got corrupted from copy paste?
Hi Nicola,
I have formatted the script in the Terminal editor (nano) because of possible errors occurred by copy/paste, and now I get no more errors about this.
The startup item should now set correctly because there are entries of “servoy” in the /etc/rc*.d/. But now it comes:
administrator@debian-6-server:~$ sudo /etc/init.d/servoy start
start-stop-daemon: unrecognized option '--quiet '
Try 'start-stop-daemon --help' for more information.
/etc/init.d/servoy: 141: : not found
Ok, the daemon don’t like the “–quiet” option and I have removed it in the codelines. Now the finally error is “/etc/init.d/servoy: 141: : not found” (line 141 is now the last of the script!).
Here is my modified script:

EDIT
The Servoy App Server is now starting automatically on reboot of the Debian server, but the manual restart/stop function will not work.
sudo /etc/init.d/servoy restart

Regards and once more thank you Nicola,
You’re welcome.
About the error: you are missing a semicolon, this is how the file should end:
#echo "Usage: $SCRIPTNAME {start|stop|restart|reload|force-reload}" >&2
echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload}" >&2
exit 3
;;
esac
:
Don’t fotget the last semicolon!
Hi Nicola,
I have added the “:” (doublecolon? I think semicolon is a “;”, or?) on the end of the script.
Now it is working. I can start/stop/restart() the servoy server by "sudo /etc/init.d/servoy ()", but only on stop I get no error.
Anyway, it’s doing what it should do and I will investigate a little bit more the script code and the way I have installed/configured it.
You helped me a lot and I could save time to get it working only by myself.
Regards,
Woops, I was in a hurry, it’s a “colon” (
not a “semicolon” (;).
Glad to have helped.
