is a link to them in the sites-enabled or mods-enabled directory. Instead of making the links manually, use the a2enmod and a2dismod commands to enable or disable modules, and the a2ensite and a2dissite commands to enable or disable specific site configurations. Testing and activating the configuration Once all modifications have been made, and the appropriate sites or modules enabled, it is best to test the configuration for obvious errors.

The main impact is more subtle—Debian is guided by a social contract, and a community of developers committed to the idea of quality, free software, widely available, that runs as trouble-free as possible in as many environments as possible. With that, let's take a look at the Debian Project itself. The Debian Project
