stop/restart servoy server by terminal

[tgs]

Hi,

how can I stop/restart the Servoy App server by Terminal?
I couldn't find any function in the wiki.

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:

Code: Select all

./etc/init.d/servoy_server start/stop/restart

?

A script example would be very appreciate.

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:

Code: Select all

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,

[ngervasi]

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.

[tgs]

I have tied to install the script into the runlevels by "update-rc.d" and I get:

Code: Select all

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:

Code: Select all

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.

[ngervasi]

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:

Code: Select all

# Default-Start:     2 3 4 5
# Default-Stop:      S 0 1 6

I checked line 71 and it's just a plain comment:

Code: Select all

# 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?

[tgs]

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:

Code: Select all

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:

Code: Select all

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

Code: Select all

sudo /etc/init.d/servoy restart
Restarting Servoy Server: servoy_server.sh/etc/init.d/servoy: 141:  : not found
failed!

Regards and once more thank you Nicola,

[ngervasi]

You're welcome.
About the error: you are missing a semicolon, this is how the file should end:

Code: Select all

        #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!

[tgs]

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,

[ngervasi]

Woops, I was in a hurry, it's a "colon" (:) not a "semicolon" (;).

Glad to have helped.
