Defining the correct Apache document root

Question

I am pretty new to Linux and I tried to install & configure the Apache 2 on OpenSuse 12.1.

Is this the document-root? /home/username/public_html

is this correct!? see the page 3 /or 4 of the configuration guide of the HTTP server.

Document Root: "/srv/www/htdocs"
Directory; "/srv/www/htdocs"
Alias: /icons/ "/usr/share/apache2/icons/"
Directory: "/usr/share/apache2/icons"
Script Alias: /cgi-bin/ "/srv/www/cgi-bin/"
Directory: "/srv/www/cgi-bin"
mod_userdir.c: empty here nothing is filled in ;-)
include: /etc/apache2/conf.d/*.conf
include: /etc/apache2/conf.d/apache2-manual?conf
Servername linux-r4qe
E-Mail des Servername: root@linux-r4qe 

While running the apache-configuring tool I have on page 5/5

listening on
all, port 80
Standardhost
in 
SSL deaktiviert
Virtuelle Hosts
linux-r4qe in "/srv/www/htdocs", SSL deaktiviert

Is Apache installed and configured correctly?

As you might find this question a bit silly or newbie-like, here are some explanations: I have installed the LAMP some months ago - but in a wrong path.

public $unicodeslugs = '0';
    public $feed_limit = '10';
    public $log_path = '/srv/www/htdocs/basic/logs';
    public $tmp_path = '/srv/www/htdocs/basic/tmp';
    public $lifetime = '15';
    public $session_handler = 'database';
}  

I always thougth that the path should be this one here:

/home/username/public_html

Update - especially for Oliver Salzburg

see here the both links

link one with some descriptions on the OpenSuse-Case detailed description on openSuse and some Advices that are discussed over there

Answer 1

/home/username/public_html is used in addition to the default web root when mod_userdir is loaded.

Some people use that functionality to put a website inside a users home directory. But it's by no means the standard way of doing things.

The document root for a given Apache site configuration is defined by the DocumentRoot directive.

Yours is set to /srv/www/htdocs, which, to my understanding, is the default location in OpenSUSE.
