[Zope] different modes on running Zope

[Imre Oolberg]

Hi,

i am new to Zope but it already works for me, good thing it seems
to be, thanks!

My problem is to understand how to use Zope in different modes.
As i see, it could be done by itself, only ZServer; and with Apache
like PCGI and FastCGI and mod_pcgi (that one i havnt tried yet).

Only thing i cant figure out is how to get 2.3.3 working in a
single-threaded mode. I am just curious about it, is it possible any more
at all?

doc/INSTALL.txt says

There are two ways to run Zope:

--  ...

 - If you *only* want to use PCGI and you don't need multi-threaded
    operation, you can have a special program, the pcgi_publisger,
    start Zope for you.  See the WEBSERVER.txt file for details on
   ^^^^^^^^^^^^^^^^^^^^^^
    using Zope with an existing webserver.


and doc/WEBSERVER.txt is quite vague about it :( saying:


Using Zope in single-threaded mode with pcgi_publisher
------------------------------------------------------

  The installation process should create a 'Zope.cgi' PCGI file. Copy the
  'Zope.cgi' file to your web server's cgi-bin directory.

  On Unix you can also create a symbolic link to 'Zope.cgi' from your
cgi-bin
  directory. For example::

    ln -s /home/amos/Zope/Zope.cgi /usr/local/apache/cgi-bin/Zope

  At this point you should perform any other steps you web server
  requires to install and configure a CGI script.

  Note: For more information on PCGI check out Jeff Bauer's "PCGI pages",
  http://starship.skyport.net/crew/jbauer/persistcgi/.

  When your Zope.cgi file is correctly configured as a CGI script with
  your web server, you are ready to access Zope through the web. You
  should point your browser at:

    'http://youmachine.example.com:8998/cgi-bin/Zope.cgi/manage'

  (Your URL maybe be different depending on how your web server is
  configured.)

  You should be prompted to enter a username and password. Enter the Zope
  "super manager" name and password.

----------------------------
 AND WHAT I DID IS LIKE THIS
----------------------------

To get single-threaded Zope going and did the following

1. installed Zope from source like 'python w_pcgi.py'
into /home/zope/zopew

2. made /home/zope apache's DocumentRoot and let it treat all files
ending as .cgi CGI scripts

3. assured apache treats http://localhost/zopew/test.cgi as CGI and
executes it.

4. without starting Zope with ./start and without redirecting Auht.
headers from apache i issued in a brauser

http://localhost/zopew/Zope.cgi/manage/, and without ending slash and
without manage/ but nothing happened. It tired and eventually timed out.
(with message  - Temporarily Unavailable, i believe its Konquerer)

I expected it to start to communicate with Zope, without ZServer.

When i tried to run ./Zope.cgi from the command line, it hanged to, seems
like waiting for input.

Practically i can do very well without single-threaded mode but
i have a old machine and there runs weird Zope, what i try to understand.

it has proccesses like

nobody    1605  0.0  0.3  6720 3464 ?        S    Jun06   0:15 python  /mnt/Zope-1.10.3/pcgi/pcgi_publisher.py
nobody    1608  0.0  0.3  6720 3464 ?        S    Jun06  11:56 python  /mnt/Zope-1.10.3/pcgi/pcgi_publisher.py
nobody    1609  0.0  0.3  6720 3464 ?        S    Jun06   3:00 python  /mnt/Zope-1.10.3/pcgi/pcgi_publisher.py
nobody    5798  0.2 17.1 169812 166616 ?     S    Jun06 140:29 python  /mnt/zope2/pcgi/pcgi_publisher.py
nobody    5869  0.0  0.8 12360 7780 ?        S    Jun06   3:00 python  /mnt/zope2/pcgi/pcgi_publisher.py

and i suspect it runs i this single-treaded mode, right?


Sorry for a long letter, but you know, i got a problem too!
