I'm using trac 1.2 on windows. Their documentation says it requires python2, so I pip install'd it with python2 x64, and spent a lot of time configuring some trac environments. Now I want to run trac through apache httpd so I can set it up with microsoft active directory, so I figured, okay, let's try mod_wsgi. I read this mod_wsgi documentation which mentions that python2 is built with VC9, and that apache, mod_wsgi, python binaries need to be consistent architecture throughout. So that means, for me, VC9, x64 for all. I installed the VC9 runtime from here. For mod_wsgi, I pip installd it using the mod_wsgi‑4.6.4+ap24vc9‑cp27‑cp27m‑win_amd64.whl file from here to avoid having to install VS2008's entire toolchain. Now I guess I need apache x64 VC9. The apache binary closest to VC9 I could find was VC10 here which says it loads VC9 modules, so I went ahead and tried it. I ran mod_wsgi-express module-config which gave me
LoadModule wsgi_module "c:/python27/lib/site-packages/mod_wsgi/server/mod_wsgiNone"
WSGIPythonHome "c:/python27"
The first line wasn't right, since httpd complained it couldn't load the module, so I changed it to
LoadModule wsgi_module "c:/python27/lib/site-packages/mod_wsgi/server/mod_wsgi.pyd"
I verified that that module exists at the specified path, and ran httpd which still error'd out with
httpd: Syntax error on line 179 of C:/Apache24/conf/httpd.conf: Cannot load c:/python27/lib/site-packages/mod_wsgi/server/mod_wsgi.pyd into server: The specified module could not be found.
So I guess the VC10 x64 apache binary I downloaded isn't backwards compatible with VC9 x64 mod_wsgi.
Does this mean I now need to build my own VC9 x64 apache binary? There must be a simpler way to achieve running trac 1.2 within an apache web server, right? Unfortunately, it's not as obvious to me. Any help is appreciated. Also, let me know if I need to clarify any other detail.
1) I am trying to setup a WAMPServer and am stuck on which file I need to download from the site: http://www.lfd.uci.edu/~gohlke/pythonlibs/#mod_wsgi
I am using: Windows 7(64 bit), Apache 2.4.9 and Python 2.7.
2) Also, many of the tutorials I have seen on the matter say to download a .so file. However the above link contains .whl files?
I've been using this https://stackoverflow.com/a/20128269/2268507 as a guide.
I would really appreciate it if someone could shed some light on these two matters.
Thank you for your help.
That page on the gohike site tells you to go read:
https://github.com/GrahamDumpleton/mod_wsgi/blob/master/win32/README.rst
Did you do that?
That page for mod_wsgi explains what version you should use for what. It does this in reference to the binaries that the mod_wsgi downloads list has, but if you understand what Python wheels are then you can use those from the gohike site as well.
UPDATE
Note that details at this URL are obsolete. You should use pip install as described at:
https://pypi.python.org/pypi/mod_wsgi
Once installed, run mod_wsgi-express module-config to display config you should add to your Apache configuration file to load mod_wsgi that you installed using pip install.
Yes, read the Graham's [Git] and take a look at paragraph:
"
Note that Apache Lounge never made available any Win64 VC9 binaries for Apache 2.4. This means that technically there is no combination available for correctly running mod_wsgi with a Win64 VC9 version of Python 2.6 or 2.7.
History shows that users simply don't want to accept this and don't want to understand that mixing VC9 and VC10 binaries are not guaranteed to work.
"
See that? don't use Python 2.6 or 2.7 in Win64, Apache doesn't support the module for you.
But you can still download the ".so" file in here , just found which is the best and suit for you and install it into Apache. This is the tutorial how to install mod_wsig to Apache and XAMPP. Good Luck!

I am a newbie to Stack Overflow (first post), but really see the use of this website.
I'm stumped. We are trying to setup IIS 7.0 to run with WinPython 2.7 on a Windows 7 machine.
I am an IIS newb, but veteran Python user. IIS 7 can NOT find a library, which python finds, and executes, perfectly when ran on it's own. When executed via IIS, the script fails with a traceback, and IIS returns the 502.2.
I found this thread http://forums.iis.net/p/1209465/2073173.aspx?HTTP+Error+502+2+Bad+Gateway+Frustrations but the advised solution is simply another troubleshooting suggestion.
I found IIS's description (http://support.microsoft.com/kb/942057) of the error helpful, but futile.
I found Python's start-up options/parameters helpful (http://docs.python.org/2/using/cmdline.html), but futile.
I found IIS's advice for configuring Python helpful (http://support.microsoft.com/kb/276494, but (questionably?) incomplete.
This thread on manually defining an alternate bin folder (http://forums.asp.net/t/1303052.aspx?Tell+IIS+to+load+dll+from+another+directory+not+Bin+web+config+) might be where my solution lies, but I don't think it is because of the fact that this all worked on 2.6 without doing that to IIS.
IIS seems to allow python to import any module that is just a python script. As soon as it gets to a *.pyd (basically just python's version of a dll file) file, it screams. I'm no pro when it comes to DLLs and windows environments, but wouldn't IIS have to have paths to a bin folder of some kind? Do I have to manually edit them, as discussed in the last link above?
ACTUAL ERROR Details below for DLL failed Load:
The Error :

I'm confident that the python environment is configured properly, as the script runs from the same executable (python.exe) via a command line. I'm thinking that I don't have IIS configured properly, for the new Python 2.7 install. The same script worked yesterday, on IIS and python 2.6. But during our upgrade from 2.6 to 2.7, a bunch of PATH and PYTHONPATH parameters all changed, plus we went from ActivePython to WinPython. WinPython is "registered" on the machine.
What I've tried
confirming python's sys.path is as expected at run-time in both IIS and command line - it is.
using the module from python command line.
recompiling the failing module using two different compilers (ming32 and VS2008).
putting duplicates of my new 2.7 modules in the old python26 folder.
pulling out lots of hair and other hacky stuff.
My next step, is to post this same message on a python forum. If anybody can advise on a good one for python-IIS related challenges, that would be appreciated.
Please help! Thanks in advance.
I got this 502.2 error when doing a clean installation of PHP 5.5 in Windows Server 2012 R2 with IIS 8.5.
It turns out PHP is a Visual C++ application which needs the library MSVCR110.dll in order to run properly. My computer does not have Visual Studio 2012 installed and thus it does not have this file. I got my problem solved by installing the Visual C++ Redistributable Packages https://www.microsoft.com/en-us/download/details.aspx?id=30679#
(Note: jc77 is my associate, and I'm actually the OP, as this was an x-post from IIS forums.)
We solved the problem.
tl,dr; portable python + sloppy/rookie compiling = strange behaviour + frustrations.
Bottom line, compile properly. For scikits.timeseries, using ming32 everything will walk, talk, and sound like it works in Spyder.exe, but not in python.exe. You have to use VS2008, if you want it to work in both.
More Info:
Winpython (as well as others) presents itself as identical to any other python installations, if you "register" the installation. It works great, 99% of the time. We learned the hard way, that "Winpython Interpreter.exe" and "python.exe" provided in the install are in fact different. Can't explain why, but the two executables gave different behavior. We were doing all our testing in Spyder, which must use "winpython interpreter.exe". The module which IIS couldn't find, would import and run no problem in Spyder. Then, in IIS, using python.exe, the module wouldn't import. We were operating on the assumption that the IDE would use python.exe, and that the stack was identical. As, 99% of the time, they appear to be. The way we were compiling scikits worked in winpython interpreter.exe. We were making a rookie mistake when compiling scikits, but it went un-noticed because it was working fine in our IDE (Spyder).
I'm adding these keywords for others : Anybody else who receives errors like this is likely using a portable python installation AND not compiling something properly. Winpython, Portable Python, eGenix, [and possibly?] Active State and Enthought Canopy.
While trying to configure CGI to run Perl in Windows 8.1, I had HTTP Error 502.2, but then I read loste's post and solved the problem. I had previously installed both Perl64 and Strawberry Perl. Although the IIS EventHandler pointed to only the Perl64 directory, both directories appeared in my Windows PATH variable. I prefer Strawberry Perl, so I changed the EventHandler to point to the Strawberry Perl directory and deleted the paths to Perl64 from the Windows PATH variable to solve the error.
Try this
print("Content-Type: text/html\n")
print("Hello Python World!")

I installed the Windows (32bit) BitNami DjangoStack 1.4.1.0 and elected not to install the python that came with it as I already have Python 2.7 installed.
I got the error below and also an internal server error when I clicked on the button in the introduction web page (so Appache is running ok)
enter code here
[error] mod_wsgi (pid=3990): Target WSGI script '/opt/bitnami/apps/django/scripts/django.wsgi' cannot be loaded as Python module
I found a similar question but that related to installing on Amazon. Also following through the answers it appeared that the problem is that the wsgi had been compiled against the wrong python version.
I then uninstalled BitNami and re-installed using the python version that was provided - still the same message.
I don't see how the wrong python version can be the problem if the BitNami package is self contained, i.e. comes with all the bits needed to run.
In case my previously installed version was causing the problem I remove it from the PATH environment variable.
Also the documentation for Windows seems wrong. django.conf and django.wsgi are not where the docs say they are (\Users\user\BitNami SDjangoStack projects\apps). In fact the only thing in that directory is the new project I selected on installation - no apps directory. I found the files in the BitNami directories.
Also when I typed python in the BitNami console I got python 2.7.3, not 2.7.2 which is listed in the installation guide.
I thought this package would be wonderful to help me get a production Django site running. It is now ready in the development phase to go live for testing.
What do you exactly mean with not installing Python? BitNami DjangoStack is self contained in the sense that it includes its own Python and its dependecies. Also you mentioned that you are running it on Windows but the path /opt/bitnami is the default path when installing as root in Linux. What exact options did you select during the installation?
I actually had mod_wsgi working with python3.1, but after updating some software... it no longer works.
I followed these instructions for python3.1 modified slightly for 3.2:
https://wiki.archlinux.org/index.php/Mod_wsgi
and while it seems to build/install ok, trying to start apache give me the error :
Cannot load /etc/httpd/modules/mod_wsgi.so into server: /etc/httpd/modules/mod_wsgi.so: undefined symbol: PyCObject_FromVoidPtr
just as this guy got:
Python 3.1.1 with --enable-shared : will not build any extensions
Any help would be appreciated.
I am a linux noob.
The released versions of mod_wsgi cannot be used with Python 3.2. You must currently use source code directly from subversion repository for mod_wsgi. See:
