[Trac] Trac on Apache Server with mod_python

[akabat]

Hi,

I'm just doing a Trac installation.
I'm running Trac on an Apache Webserver with mod_python on a Windows
machine. In the Trac Guide there is written this:


======================================
Generating the Trac cgi-bin directory ¶


In order for Trac to function properly with FastCGI or mod_python,
you
need to have a trac.cgi file. This is an executable which loads the
appropriate Python code. It can be generated using the deploy option
of trac-admin.


There is, however, a bit of a chicken-and-egg problem. The trac-admin
command requires an existing environment to function, but complains
if
the deploy directory already exists. This is a problem, because
environments are often stored in a subdirectory of the deploy. The
solution is to do something like this:


mkdir -p /usr/share/trac/projects/my-project
trac-admin /usr/share/trac/projects/my-project initenv
trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy
mv /tmp/deploy/* /usr/share/trac

======================================


Now my questions:
1. Do i have to do that really? It works without that, too.
2. Whereto do I copy the generated directories? In my Apache
installation or in my Trac environment?


Thanks in advance!

Umm, is there any reason why you are using mod_python? From what I researched, mod_wsgi seems to be the recommended and actively maintained alternative with some excellent documentation by Graham Dumpleton:-

...you will need to create a .wsgi script for Trac using mod_wsgi but Graham provides excellent examples in the links above.

No problem, I hope this helps...

I installed the version 0.11.7 of Trac because I didn't want to
install a beta version. And in the 0.11 Trac Guide they recommend
mod_python.

As far as I know mod_python is currently unmaintained (last update at http://www.modpython.org/ is listed as Jan 2008) and has "some issues" which are therefore unlikely to be fixed.

WSGI seems to be a modern standard way to support python web apps and is currently actively developed and supported (as mod_wsgi) by Graham Dumpleton. If you search t.e.o you will find pages about using mod_wsgi: http://trac.edgewall.org/wiki/TracModWSGI but just checking does show that the standard install doc uses mod_python and ignores mod_wsgi...

Anyway, in summary I use mod_wsgi for a multi-parent-root setup on windoze server and am very happy with it.

Not sure who wrote that bit of documentation, but it is entirely
wrong. See https://coderanger.net/~coderanger/tracdoc/install/
mod_python.html
