1. Install Apache
./configure –prefix=/usr/local/apache2 –enable-so –enable-rewrite –with-mpm=prefork
make
make install
rm -Rf /usr/local/apache2/htdocs/*

2. Install mod_python-3.3.1

./configure --with-apxs=/usr/local/apache2/bin/apxs
make
make install

3. Install Python Imaging Library (PIL) – Imaging-1.1.6

python setup.py install

Note: To check if PIL was successfully installed:
#python selftest.py
***Test Failed*** 1 failures.
*** 1 tests of 57 failed.

47 ln -s /usr/lib/libjpeg.so.62 /usr/lib/libjpeg.so
48 ldconfig
49 python setup.py install
51 python selftest.py
54 rm -rf Imaging-1.1.6
55 tar -zxvf Imaging-1.1.6.tar.gz
56 cd Imaging-1.1.6
58 python selftest.py -> still fails
59 python setup.py install
60 python selftest.py -> ok

4. Check if mod_python was sucessfully installed.
http://www.dscpl.com.au/wiki/ModPython/Articles/GettingModPythonWorking

[root@rupert-centos pytest]# python
Python 2.4.3 (#1, Mar 14 2007, 18:51:08)
[GCC 4.1.1 20070105 (Red Hat 4.1.1-52)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import mod_python
>>> mod_python.version
'3.3.1'
>>>

4. Edit httpd.conf

<directory>
 AddHandler python-program .py
 PythonHandler TileCache.Service
 PythonOption TileCacheConfig /usr/local/apache2/htdocs/tilecache/tilecache.cfg
 PythonDebug On
 PythonPath "sys.path + ['/usr/local/apache2/htdocs/tilecache/']"
</directory>
 
<directory>
 AddHandler mod_python .py
 PythonHandler test
 PythonDebug On
</directory>

Note: This syntax will work for all versions of mod_python. In version 3.0 and later, the name of the mod_python handler reference has actually been changed and thus it is now preferred to use “mod_python” instead of “python-program”. The old name though is still supported and will be used here to avoid confusion for those using version 2.7.

5. Test your python

from mod_python import apache
 
def handler(req):
      req.log_error('handler')
      req.content_type = 'text/plain'
      req.send_http_header()
      req.write('mptest.py\n')
      return apache.OK

http://www.python.org/download/releases/2.5/

http://httpd.apache.org/modules/python-download.cgi -> click on win32 binaries. Get the mod_python-3.3.1.win32-py2.5-Apache2.2.exe if your Apache is running on 2.2.

http://www.pythonware.com/products/pil/

http://effbot.org/downloads/PIL-1.1.6.win32-py2.5.exe

3. Install python2.5

4. Install mod_python and python_imaging.

5. Edit httpd.conf

LoadModule python_module modules/mod_python.so
 
<directory>
AddHandler python-program .py
PythonHandler test
PythonDebug On
</directory>
 
<directory>
	AddHandler python-program .py .cgi
	PythonHandler TileCache.Service
	PythonOption TileCacheConfig /wwwroot/tilecache/tilecache.cfg
	PythonDebug On
</directory>
 
ScriptInterpreterSource Registry
SetEnv PYTHONUNBUFFERED 1
PassEnv PYTHONPATH

6. run regedit. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.4\PythonPath. Append “E:\wwwroot\tilecache” to PYTHONPATH

D:\Python24\Lib;D:\Python24\DLLs;D:\Python24\Lib\lib-tk;E:\wwwroot\tilecache;

7. Put D:\Python24 in your WINDOWS PATH

8. Test if apache could read python by http://127.0.0.1/pytest/test.py

9. http://127.0.0.1/tilecache/test1.cfm

10. tilecache_seed.py “http://127.0.0.1/tilecache/tilecache.py” roads 12 17 “116.28229,39.85291,116.48657,39.98783″
