As the error message says, set the MOD_WSGI_APACHE_ROOTDIR environment variable to its location before running the pip command. So equivalent of:

MOD_WSGI_APACHE_ROOTDIR="C:/xampp/apache"

How you set it will depend on the shell you use.

Use forward slashes, not backwards slashes.

Hi @GrahamDumpleton, thanks for your prompt reply. I have tried this. The installation of mod_wsgi was successfull. But when I try to start the server by, it doesn't allow me. Following is the text from command prompt:

D:\Vishesh\DjangoProjects\vishTest>mod_wsgi-express start-server
Usage: mod_wsgi-express command [params]
Commands:
    module-config
    module-location
mod_wsgi-express: error: Invalid command was specified.

On Windows mod_wsgi-express is only used to work out the configuration you need to add into your normal Apache instance. You then need to configure the normal Apache instance for your specific WSGI application and use normal method to start Apache. You can't use mod_wsgi-express start-server on Windows.

Yes but for that I'll need the mod_wsgi.so file. I am not able to find that for the python version I am using. Please tell where can I find the .so file.

Run:

mod_wsgi-express module-config

That command tells you what to put in the Apache configuration file

See section 'Connecting into Apache installation' in:

• https://pypi.python.org/pypi/mod_wsgi

Thanks @GrahamDumpleton, that worked. I have deployed the server on Apache. But, there is one more problem. I am able to access the Django app from my own machine only. If I try opening the django app from another machine on the LAN, the request gets timed out and the page never loads. Please suggest what may be causing this problem.

Hi @GrahamDumpleton. I somehow figured out that Firewall was the problem. It was blocking the ports. Thanks a lot for your help.

@dungneo Please don't ask a new question in a comment to an existing issue. Create a new issue and I will deal with it there.

@dungneo Since you haven't gone on to create a separate question, what I will say is that it appears you haven't actually configure mod_wsgi to say what your WSGI application is. Eg. using WSGIScriptAlias. As a result, due to an existing AddHandler cgi-script .py directive in your configuration, it is being executed as a CGI script and not even using mod_wsgi. Please refer back to the documentation on configuring mod_wsgi at:

• http://modwsgi.readthedocs.io/en/develop/user-guides/quick-configuration-guide.html

Tks @GrahamDumpleton!
sorry: in .htaccess:

AddHandler cgi-script .cgi .pl .py

--> it's not working... apache can't start!

apache ok! it run! but need shebang #!C:\Python\Python36-32\python.exe in first line in index.py to run

i don't want shebang in shebang #!C:\Python\Python36-32\python.exe in first line in index.py to run!
can u help me!
tks!!!!!

Are you sure you mean .htaccess file? VirtualHost and WSGIScriptAlias cannot be used in a .htaccess file, they can only be used in the main Apache configuration file.

When you ran:

mod_wsgi-express module-config

did you actually copy the output of that into your Apache configuration file. You can't just run it alone as it does not modify the Apache configuration file for you.

If you didn't add it, then WSGIScriptAlias will generate an error when used in the Apache configuration file.

You don't show the error you get when Apache can't start to confirm what you are doing wrong.

Tks!

into your main Apache configuration file?

If you do not do that then mod_wsgi will not be loaded and use of WSGIScriptAlias will cause an error.

You need to add:

LoadFile "C:/Python/Python36-32/python36.dll"
LoadModule wsgi_module "C:/Python/Python36-32/lib/site-packages/mod_wsgi/server/mod_wsgi.cp36-win32.pyd"
WSGIPythonHome "C:/Python/Python36-32"

into the Apache configuration file at a location which is before any place where you use the mod_wsgi directives. You have added it after the VirtualHost which presumably includes the WSGIScriptAlias directive. That will not work. Move those lines before the VirtualHost, placing it just after any existing LoadModule directives.

Tks!

*.py need shebang!!!?!

Have you added back the WSGIScriptAlias line?

Remove any line which says:

AddHandler cgi-script .py

as you don't want it and it will cause problems.

Alternatively use a .wsgi extension for Python web application code files that you want to use with mod_wsgi.

In error.log

mod_wsgi (pid=10972): Target WSGI script 'C:/Python/Web/Hello/index.wsgi' does not contain WSGI application 'application'.

tks!

Your script file likely then isn't a WSGI application. The mod_wsgi package is not for running CGI scripts. Use the sample WSGI application of:

def application(environ, start_response):
    status = '200 OK'
    output = b'Hello World!'

    response_headers = [('Content-type', 'text/plain'),
                        ('Content-Length', str(len(output)))]
    start_response(status, response_headers)

    return [output]

If that works, then go learn about WSGI applications. Preferably go use a framework such as Flask rather than trying to implement WSGI applications from scratch.

Tks! @GrahamDumpleton so much!

Hello/index.wsgi >>> Hello World!

Do you have skype?! i want ask u about python!?!

Sorry, I can't work with you one on one.

If you have questions about Python, trying using StackOverflow or find a local Python user group which you can join.

ok tks u!

i wan to know best of server for python code:
Apache + WSGI or CherryPy or NGINX or ??

what u choose?!?!

You really should focus on getting your WSGI application working first. Implement your WSGI application properly and it should be portable and able to run on any WSGI server. So get your application running and worry about choice of WSGI server later.

ok! tks @GrahamDumpleton so much!

I had issues with installed different python versions on my Windows 2012 server with apache.
Using this code in httpd.conf helped me:

LoadFile "C:/Python/Python36-32/python36.dll"
LoadModule wsgi_module "C:/Python/Python36-32/lib/site-packages/mod_wsgi/server/mod_wsgi.cp36-win32.pyd"
WSGIPythonHome "C:/Python/Python36-32"

@GrahamDumpleton i am trying to install mod_wsgi module in Windows 10, but I am getting following error:

Traceback (most recent call last):
File "", line 1 , in

raise RuntimeError('No Apache installation can be found. Set the 'RuntimeError: No Apache installation can be found. Set the MOD_WSGI_APACHE_ROOTDIR environment to its location.'

I am using apache 2.4 bundled in xampp 3.2.2.
The location of apache instalation folder is "E:\xampp\apache"
according to u i ran this command MOD_WSGI_APACHE_ROOTDIR
IT SHOWS IT IS NOT RECOGNIZE AS INTERNAL OR EXTERNAL COMMAND AND IAM USING COMMAND PROMPT SO PLEASE HELP ME

Please don't ask question as a comment on existing issues, especially closed issues. Create a new issue.

Please don't ask new questions on existing issues, especially one which is closed. I will say though I don't think you will be able to do it. The problem is that Python 2.5 requires a really old MS C/C++ compiler, and it is going to be incompatible with the compiler version Apache 2.4 uses.
