How would you move a site from a python web server to IIS 8?

For what it is worth, I have web2py deployed under IIS using the ISAPI 
recipe and web2py screams in speed. The only requirement is the code has to 
be thread safe and have not yet run into thread safe problems in how we 
deploy web2py. If it is, you will get much faster performance over fastcgi.

This helped me a lot. Thanks. Do you know if the 'scriptProcessor' can be 
set relatively?

Could you put this in the book? Thanks Tim.

[Tim Richardson]

Ok. Some tips to a future me if I have to do this again.

wfastcgi is now a module. So currently the deployment instructions in the 
web2py book give a download link. It's not necessary any longer. But some 
paths have changed, and the configuration process is more automated.
 
https://pypi.python.org/pypi/wfastcgi

1) install it with pip

2) as administrator command prompt, run the executable 
PYTHON_ROOT/Scripts/wfastcgi-enable.exe 
This will update your IIS config. It seems to change the FastCGI setting at 
the server level of the config

It also sends some output to standard output, as described in the readme at 
the pypi page above.

If you follow the deployment instructions in the web2py book, you will have 
a web.config file at the root of your web2py folder. 

To finish updating the IIS configuration, you could copy the settings from 
https://pypi.python.org/pypi/wfastcgi into the web.config page. 
This meant, for me, adding a section like this:


 
   


I didn't have the handlers section in the existing file. The 
scriptProcessor value involves a pipe. You can copy that value from the 
output of step (2). 
When IIS starts, it will read from the file and update its configuration. 
But it can only do that if you change Feature Delegation -> Handler 
Mappings to Read/Write. It defaults to Read, which means the server gives 
errors at start up which look like this: "The requested page cannot be 
accessed because the related configuration data for the page is invalid"

Get that sorted, and IIS will copy into its configuration the correct 
setting. You can observe by going to the site setting for your web2py app 
in IIS configuration, and views Handler Mappings. There you will see a 
handler Python FastCGI configured according to the path above. You could 
bypass the text file and set this up in IIS settings directly, per screen 
shot. If you have existing IIS setup, you could probably just change the 
path. I didn't know what I was doing so I didn't take this shortcut.

OK. So I updated web.config like so:


 
 
   
 

and allowed the text file to update handlers (Server node->Feature 
Delegation -> Handler Mappings to Read/Write).
This means that IIS will read the text file and store the configuration it 
finds, so that I now see under the site which I call web2py 
handlers -> Handler Mappings

there is a value under Executable (optional) matching the scriptProcessor 
value above. 

Now I get 

HTTP Error 500.0 - Internal Server Error  scriptProcessor could 
not be found in  application configuration

And then web.config, a file in the root of the relevent web2py 
installation, needs to be changed as well.
