Python installation?

[Secret Agent]

I want to install Python on a web hosting server with cPanel. How do I check if it is installed or not? If not, how do I install? Any downside to using Python for a web hosting server?

root@server [~]# rpm -q python
python-2.3.3-6

root@server [~]# rpm -q mod_python
mod_python-3.1.3-1.fc2.2

I believe I may have to edit httpd.conf ? What changes?

Thank you in advance

Using:
Fedora Core 2
Cpanel 10.0 R-112

This is probably all you need for apache:
LoadModule python_module modules/mod_python.so

It might already be ok if your current config is looking at /etc/httpd/conf.d/ (which are the extra configuration files).
See /etc/httpd/conf.d/python.conf for specifics.

My httpd.conf shows nothing of "python" but the python.conf is the following entirely below

#
# Mod_python is a module that embeds the Python language interpreter
# within the server, allowing Apache handlers to be written in Python.
#

LoadModule python_module modules/mod_python.so

# Override type-map handler for /var/www/manual
<Directory "/var/www/manual/mod/mod_python">
<Files *.html>
SetHandler default-handler
</Files>
</Directory>

# This will cause files beneath /var/www/html with the extension .spam
# to be handled by the Python script /var/www/html/eggs.py
#
#<Directory /var/www/html>
# AddHandler python-program .spam
# PythonHandler eggs
#</Directory>

# This will cause all requests to the /python heirachy of your
# webserver to be handled by the python script /path/to/myhandler.py
#
#<Location /python>
# SetHandler python-program
# PythonPath "sys.path + ['/path/to']"
# PythonHandler myhandler
#</Location>

# This will cause all requests to the /python heirachy of your
# webserver to be handled by mod_python's Publisher handler
# (see http://localhost/manual/mod/mod_python/hand-pub.html)
#
#<Location /python>
# SetHandler python-program
# PythonHandler mod_python.publisher
#</Location>

# This will cause the output of all requests to files beneath
# /var/www/html with the extension .flt to be filtered through
# the Python script /var/www/html/filter.py
#
#<Directory /var/www/html>
# PythonOutputFilter filter MYFILTER
# AddOutputFilter MYFILTER .flt
#</Directory>

can someone please help me?

[5amYan]

is the python.conf in /etc/init.d ?
Are you on an RH based distro?
if so try
uncommenting the following, but ***note***>> the absolute path (make sure it is valid for your system.)
# This will cause all requests to the /python heirachy of your
# webserver to be handled by mod_python's Publisher handler
# (see http://localhost/manual/mod/mod_python/hand-pub.html)
#
<Location /usr/local/www/data/python> ## or in FC maybe /var/www/html/python
SetHandler python-program
PythonHandler mod_python.publisher
PythonDebug On
</Location>

Then put something like the following in the /directory/path/you/chose/hello.py

from mod_python import apache

 def handler(req):
     req.content_type = "text/html"
     req.write("Hello World! Hello __self__!")
     return apache.OK

And read the mod_python documentation

luck. let me know how it goes.

Before I do anything let me show you what I have and please explain to me what I should do

root@server [~]# locate python.conf
/etc/httpd.old/conf.d/python.conf
/usr/local/apache/conf.d/python.conf

[Secret Agent]

This is my python.conf file (/usr/local/apache/conf.d/python.conf

Please tell me what I should edit here (thank you)

#python.conf
<Location /var/www/html/python>
SetHandler python-program
PythonHandler mod_python.publisher
PythonDebug On
</Location>

/etc/init.d/httpd restart # Don't forget to restart apache

#/var/www/html/python/test.py
# test.py
def main(req, name="Secret Agent!"):
return "Hello %s" % name

[Secret Agent]

I'm sorry but I"m confused here. What exactly am I suppsoed to do with the pieces you showed me?

[5amYan]

#python.conf <<<<----- Goes in this file that you cut and pasted earlier. If you are using FC3 w/ SElinux bindings you won't be able to do it in /python It will have to be in the /var/www/html tree.
Also I added debugging so you can deug problems you experience.
<Location /var/www/html/python>
SetHandler python-program
PythonHandler mod_python.publisher
PythonDebug On
</Location>

/etc/init.d/httpd restart # Don't forget to restart apache as root or sudo

#/var/www/html/python/test.py The following goes in a file called test.py in the /var/www/html/python tree declred to be handled by mod_python.publisher above.
# test.py
def main(req, name="Secret Agent!"):
return "Hello %s" % name

point browser at http://yourURL/python/test.py

[Secret Agent]

Ok... I inserted

<Location /var/www/html/python>
SetHandler python-program
PythonHandler mod_python.publisher
PythonDebug On
</Location>

at the very end of /usr/local/apache/conf.d/python.conf

Then restarted apache

But, /var/www/html/python does not exist inside /var/www/html

So I can't test the test.py

Am I supposed to create that directory or something? Also, if I remember correctly I'm supposed to enable mod_python in httpd.conf (however 'python' is not found anywhere in httpd.conf so i have to add loadmodule / addmodule ??)

I'm not familiar with cPanel, but are you just trying to write CGI scripts? If so, I don't think any of this is necessary. You just need to write scripts within your cgi-bin that a user can then request. When the user requests your script, any printing you have done to standard output will effectively be sent to his/her browser and displayed as a webpage (thus you will likely want/need to print out the necessary html tags). This is great when you need dynamic material.

As I said though, I'm not familiar with cPanel. You may be trying to do something completely unrelated.

[Secret Agent]

Basically my clients were requesting mod_python

I just want to enable mod_python

[jayemef]

I see. This is good, as mod_python is significantly more efficient than traditional CGI. I don't have much background with it though, unfortunately, so I don't really have any tips. Have you checked http://www.modpython.org/? The documentation and FAQ could be helpful.

[Secret Agent]

I don't know whats wrong with me but I cannot seem to get it right.

http://www.modpython.org/live/mod_py...configure.html

I did:

root@server [/usr/local/apache/bin]# ./configure --with-apxs=/usr/local/apache/bin/apxs
-bash: ./configure: No such file or directory

That apxs path is in fact correct and apxs is there in that directory too. Not sure what I am missing.

root@server [/usr/local/apache/bin]# python
Python 2.2.3 (#1, Feb 15 2005, 02:41:06)
[GCC 3.2.3 20030502 (Red Hat Linux 3.2.3-49)] on linux2

root@server [/usr/local/apache/bin]# ./configure --with-python=/usr/local/src/Python-2.0
-bash: ./configure: No such file or directory

Right, I'm a noob but please help me
