Re: [Webware-discuss] "./AppServer stop" Fails

[Gary Perez]

I have the same problem on a daily basis. My method to restart the 
AppServer is to check the appserverpid.txt file in the runtime 
directory (not the Webware/WebKit) directory, and kill that PID. Then, 
"./AppServer &" to start again. I wrote a Python script that will 
either read that PID file and kill it, or parse the output of "ps aux" 
and kill the appropriate PIDs. I can give that to you if you want. You 
can do it through WebKit, if desired, but should do so through the 
OneShot.cgi adapter, in case you need to restart the server after it's 
gone to lunch.

This probably doesn't solve your problem, but I hope it helps a bit.

Hi,

I am practicing the installation and running of my Webware app on a
dedicated remote hosted linux server with ssh and WebMin access.
A starting assumption is the way to start the AppServer is to ssh in
and start it in the normal manner and then disconnect, leaving it
running. Per the docs, I should be able to start another ssh session
and issue a:
   ./AppServer stop
This fails in the "stop" function of AppServer.py trying to:

pidfile = os.path.join(os.path.dirname(__file__),"appserverpid.txt")

...which points to the WebKit directory.

The problem seems to be the "recordPID" method of AppServer.py stored
the PID in the mycontext directory:
pidfile = open(os.path.join(self._serverSidePath,
"appserverpid.txt"),"w")
I was testing with the 8.0 release; the CVS version of AppServer.py
seems to have some code changes but the directory mismatch appears to
persist. I think the mycontext directory is the right place for the PID
file to be stored, but the "stop" function (as I understand it) doesn't
have a way to find the mycontext directory ("stop" is called from the
"main" function in ThreadedAppServer.py).
Using the "admin" function to stop the AppServer is probably an easy
way around this, but I understand the recommendation is to disable the
admin functions for production sites. I tried the kill method as well,
but that doesn't seem to shut down cleanly and I was unable to restart
the AppServer without rebooting.
Any suggestions?
