Gaining Sudo privileges to alter httpd.conf Apache2 file

For some reason I can't change the file to install php on OS X... I'm the admin and have full privileges??? do i need to access the file through terminal with sudo?

I'm trying to install PHP and am trying to change the 2 lines:

so it turns out I did have to use "sudo" to change the file.
For any1 that is curious... to access and change the apache2 file httpd.conf in order to "install" php on OS X.

you need to open terminal (WARNING: it is very easy to "F*$(" your system up if you don't know what your doing with the following)

type in:


terminal will return "Password:"
type in your admin password. (what you use to login) you need to have admin privileges on your computer to continue.

also when your typing your password... it wont show that your actually typing anything... but you really are

then hit "ENTER"
a new screen should appear... using the down arrow key... scroll to about line 115 i think... it's the end of the long list of "LoadModule" lines.

look for:

and take out the pound sign in front of the line by using the arrow keys and delete key.

then go past the next line that looks like this:

and make a new line... type in the following:


then hit "control+x"

this will ask you if you want to save the file "p.s... i would recommend creating a backup of this file in case things go wrong"

then hit the "y" character on your keyboard to confirm the changes... then hit "enter"... you will be taken back to the main terminal bash window... and your done. if you want it to be active you either reboot your machine or go into

system preferences - sharing - and uncheck and then check the box labeled "web sharing"

and you can check it by making an index.php file and placing it in the sites directory.

hope that helps

What does the filesystem for Apache look like on Mac ?

I know on Ubuntu the configuration files are setup in multiple directories and there's specific places other than the main httpd.conf to put directives. I'm just wondering if Mac is the same since I don't have access to a Mac at all.

there's several config files distributed throughout apache subfolders
if that answers your question
