[SOLVED] 505- Internal server error - The server encountered an internal error or misconfigura

physnastr · 10-30-2011, 02:58 AM

I am trying to install a software called indico on a red hat machie which needs mod_python and python. I have installed all the packages and all the modules properly and have modified the content of httpd.conf with the following content. Apache restarts properly but then i try to access it on the http://localhost/indico/index.py I get the 505 error. Can some one help me in resolving the issue and where am i making the mistake. Here is what I have added to the httpd.conf.

LoadModule python_module modules/mod_python.so

PythonInterpreter main_interpreter
PythonImport MaKaC::setEnvironment main_interpreter

<Directory "/opt/indico/htdocs">
AddHandler python-program .py
PythonHandler mod_python.publisher
Allow from All
</Directory>

<Directory "/opt/indico/htdocs/services">
SetHandler python-program
PythonHandler MaKaC.services.handler
PythonInterpreter main_interpreter
Allow from All
</Directory>

Alias /indico/images "/opt/indico/htdocs/images"
Alias /indico "/opt/indico/htdocs"

Here is the output of the apache error-log.

Code:

[Sun Oct 30 02:52:16 2011] [error] [client 127.0.0.1] IOError: [Errno 13] Permission denied: '/opt/indico/log/indico.log'

try changing ownership to the apache user or chmod to 777

physnastr · 10-30-2011, 02:46 PM

I tried changing the ownership to apache and chmod to 777 for the indico directory and it still shows up the same 501 error message.

vasile002 · 10-31-2011, 03:32 AM

but did you check the error log, did anything change there? please post it again

I dont find much of the changes in the apache error-logs.

vasile002 · 11-01-2011, 05:10 AM

it's the same permission denied error. can you try and chmod to 777 the log file?

also I can see this:
[Sun Oct 30 14:52:29 2011] [error] [client 127.0.0.1] Directory index forbidden
by Options directive: /opt/indico/htdocs/

that needs fixing as well

physnastr · 11-01-2011, 11:31 PM

Problem solved. It was not the permissions issue but some misconfiguration in the httpd.conf.
It seems to be working fine now. Thanks for the response.

Soleantelada · 11-17-2011, 04:57 PM

Can you please post the solution about the configuration error?

I'm having the same issue

Thanks
