I'm a linux newbie, help me please!?

I'm using debian linux. How do I change the default directory for apache2? I've found the configure file, but I don't have permission to change it. I could just copy drupal to the default apache2 directory, but I can't figure out how to get permission. I've tried cp in root terminal, but it says omitting directory drupal-5.2? enlighten me please.I'm a linux newbie, help me please!?
well if you can access the root shell than you can perform copy but you haveto use -r



ie

cp -r source destination



and as explained in above answer you can proceeed to change permissions using chmod.I'm a linux newbie, help me please!?
In the root terminal, you have to use the ';chmod'; command to change the permissions of the httpd.conf file, so that you can access it. More info on how to use this command can be found here:

Here's an example:

chmod a=rwx httpd.conf



This usage above will make everyone able to read, write, and execute the file.
