Alexandre,
I found the existing MS4W bug with some notes on this module (http://bugzilla.maptools.org/show_bug.cgi?id=1631
). I have added your initial comments. If you can add any further
findings of yours to that bug that would be great. To answer your
questions I made some notes as I worked through it all, which I have
added to that bug and included below:
FastCGI Config notes
====================
1) to see a list of loaded Apache modules:
- cd to /Apache/bin
- execute:
httpd -t -D DUMP_MODULES
With a fresh (no changes out of the box) MS4W you will see:
Loaded Modules:
core_module (static)
win32_module (static)
mpm_winnt_module (static)
http_module (static)
...
setenvif_module (shared)
Syntax OK
2) Edit Apache/conf/httpd.conf and add the following:
- line#117 LoadModule fcgid_module modules/mod_fcgid.so
- line#420 AddHandler fastcgi-script fcgi
Without installing the Visual C 2008 runtimes, if I try viewing
the modules again I get the following error:
httpd: Syntax error on line 118 of C:/ms4w/Apache/conf/httpd.conf:
Cannot load
C:/ms4w/Apache/modules/mod_fcgid.so into server: This application
has failed to
start because the application configuration is incorrect.
Reinstalling the
application may fix this problem.
3) after installing Visual C 2008 runtimes (www.microsoft.com/downloads/details.aspx?FamilyID=9B2DA534-3E03-4391-8A4D-074B9F2BC1BF&displaylang=en)
try to view the modules again and look for the fcgid module at the
end:
Loaded Modules:
core_module (static)
win32_module (static)
mpm_winnt_module (static)
http_module (static)
...
setenvif_module (shared)
fcgid_module (shared)
Syntax OK
4) If I place the "FastCgiConfig -minProcesses 2" command on line#145
(after the 2 existing </IfModule> tags), and try listing the modules
again I get the error:
Syntax error on line 145 of C:/ms4w/Apache/conf/httpd.conf:
Invalid command 'FastCgiConfig', perhaps misspelled or defined by a
module not
included in the server configuration
Solution:
FastCgiConfig is actually a directive for the "mod_fastcgi" module
(from fastcgi.com). In our case however, we are using "mod_fcgid",
and it has its own directives, which are all documented on http://fastcgi.coremail.cn/doc.htm
Therefore, around line#145 (after the existing </IfModule> tags), we
could have:
<IfModule fcgid_module>
DefaultMinClassProcessCount 3
</IfModule>
Give those directives a try!
Notes:
******
- the above testing was all done through commandline, which means that
PATHs are often set nicely. More testing must occur with mod_fcgid
through the browser to make sure that appropriate environment
variables are being set (these are documented on http://fastcgi.coremail.cn/doc.htm)
- the above settings in httpd.conf will be added to the ms4w 2.2.8
release (shortly!)
