[Zope] Much onfusion concerning pcgi-wrapper

Tue Nov 25 01:08:27 EST 2003

I am trying to install Zope on a web host account (no root access) that 
runs FreeBSD 4.5. It seems like I should be able to get it to work through 
pcgi-wrapper. I have gone through every bit of text I could find about 
pcgi-wrapper, and its relation to Zope.cgi, but still no luck.

If I run pcgi-wrapper by itself, it outputs the "temporarly unavailable" 
HTML. In other words, it works by itself.

I found out about using pcgifile.py, to verify that at least the basics 
were set up properly so that things _should_ work. It gives me a positive 
result I call: 
http://<siteName>.net/~<username>/cgi-bin/pcgifile.py?infofile=Zope.cgi. I 
have included the resulting output at the bottom of this email, but 
suffice to say, it seems to think things are okay.

For the sake of trying to get this all to work, I chmod'ed access rights 
for /home/<userName>/cgi-bin/Zope (and all files and directories 
underneath that) to 777.

The only thing I did differently in Zope.cgi was to change the 
PCGI_MODULE_PATH setting to point to Main.py, instead of just pointing to 
a directory. (Some documentation I found on the web pointed me to this, 
and when I did it the other way, I got an error, as it seemed to be 
expecting a file, not a directory.)

I try running it from the command line:

	./Zope.cgi

		or also just

	./pcgi-wrapper Zope.cgi

In either case, it just waits for a while, and then returns with no output.

The pcgi.log file reports no problem.

If I try calling http://<siteName>/cgi-bin/Zope.cgi, I get the 
"Temporarily Unavailable" message -- but again, nothing written to 
pcgi.log.

I make sure I am runnning Python version 2.1.3.

Other CGI files (I use Perl CGI a lot) work fine with the current Apache 
configuration.

I would so appreciate any suggestions on this, because I am really hoping 
to start learning and using Zope.

Maybe I just don't have rights on my account to be able to initiate a 
persistent process?

Thanks!
