How to start and stop apache2?

I used yast->software management to install apache2.
But I didn’t find where it is installed.
How to start and stop apach2?
Where can I find httpd.conf?

It can be done from YaST under Network Services, or from the CLI, e.g.

/etc/init.d/apache2 start

or the SUSE shortcut

rcapache2 start

httpd.conf is in /etc/apache2. However there are some things that are easily done and do not require editing httpd.conf. In fact, httpd.conf seldom needs to be edited on SUSE. In particular included modules are specified in /etc/sysconfig/apache2.

Thanks.
I got it.
It seems the commanders can only run under root user?

Well starting and stopping Apache can only be done by root (well actually by a process with effective root privilege).

How can I know which SUSE shortcuts exists?
How to list all the shortcuts?

Type su in the command line, right after rc and hit TAB twice. I think all commands beginning with rc are opensuse shortcuts (correct me if I’m wrong).

httpd.conf is in /etc/apache2
