macOS Trouble Enabling Apache on MacBook

I'm trying to teach myself PHP. I began by trying to enable Apache (MacBook running Leopard) by turning on Web Sharing in the System Preferences. I get the little green button that says Web Sharing on but when I click on either of the 2 addresses shown, when Safari launches it says "Safari can't find the server." If I enter http://localhost/ for the address, I get the same result. I thought at least this step would be easy. What am I doing wrong?

Thanks.

Searching this and other forums for help on this topic, I see references to a folder named httpd which is supposed (?) to be in the private/etc directory. I do not have this folder and after turning web sharing on, the following error message repeats in console:


8/23/08 10:00:30 PM org.apache.httpd[721] (2)No such file or directory: httpd: could not open error log file /private/var/log/apache2/error_log.
8/23/08 10:00:30 PM org.apache.httpd[721] Unable to open logs
8/23/08 10:00:30 PM com.apple.launchd[1] (org.apache.httpd[721]) Exited with exit code: 1
8/23/08 10:00:30 PM com.apple.launchd[1] (org.apache.httpd) Throttling respawn: Will start in 10 seconds
8/23/08 10:00:40 PM org.apache.httpd[725] (2)No such file or directory: httpd: could not open error log file /private/var/log/apache2/error_log.
...............and on and on

Do I need to create this folder? If so, what belongs in it?

Thanks.

Hey guys. Thanks for the replies and suggestions. Just for clarification on what I'm seeing - I have neither /private/var/log/apache2/ nor /private/var/log/httpd/.

Thanks!! I created the apache2 directory in the private/var/log directory and turned web sharing on. Both addresses (computer's website and personal website) now display pages. The newly created apache2 directory now has 3 files in it. The error_log file contains the following:

[Sun Aug 24 12:49:13 2008] [warn] Init: Session Cache is not configured [hint: SSLSessionCache]
[Sun Aug 24 12:49:14 2008] [notice] Digest: generating secret for digest authentication ...
[Sun Aug 24 12:49:14 2008] [notice] Digest: done

Look okay?
Next I am going to try to enable PHP per instructions here:

and then download MySQL. Hope this works

Thanks again.
