Apache2 Python – Fix Apache2.4.7 on Ubuntu 14.04 Not Executing Python CGI Files


Description of problem:

When I load in my browser my test.cgi is treated like a text file instead of a python file.

Ruling out the possibility of the error being related to the python code:

  • I can't get an intentional 500 error, no matter what I do to the
    python code.

  • And I've made the cgi file executable via sudo chmod +x.

  • I've done this before in previous versions of Ubuntu with out issue.


I believe the problem lies in my configuration. Below is my configuration of two files, apache2.conf and 000-default.

I've been pasting different things in to make my configuration files work, every chance I get. This is just a snapshot of what these two files look like at the time of writing this.

Thank you, in advance!

The first problem would be because the CGI module hasn't been enabled, so Apache isn't processing anything as CGI. ENable it:

sudo a2enmod cgi

In Apache2.4, the configuration was cleaned up considerably, and things in the default site definition have been moved to configuration files in conf-available. Among other things, this also includes the CGI-related configuration lines seen in the default site of older versions. These have been moved to /etc/apache2/conf-available/serve-cgi-bin.conf, which contains:

ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/

This causes the second problem. Either modify that file, or disable that configuration:

sudo a2disconf serve-cgi-bin
