missing???

Ansh;

My first thoughts are two possibilities for the "problem."

1. Apache was not completely/properly installed. Perhaps there was an error in the installation process.
2. Apache was installed properly, but the location of the conf file(s) and such are different than the documentation you are looking at.

Which OS/distro are you working with? That makes a lot of difference. I have clients on a variety of distros, and can tell you from first hand experience, they are not always set up the same.
