Configuration of apache2

It seems that apache, which is included by default in the mac, is running, even though I thought I had done a lot of setting up in macport.
I want to unify the software I put in macports.

First, stop the one that comes by default on the mac.これは違うぽい
Stop with /usr/sbin/apachectl -k stop.

OK to start with /opt/local/apache2/bin/apachectl start

The one that comes by default on mac: /usr/sbin/apachectl
The one I put in macports: /opt/local/apache2/bin/apachectl

That's confusing.

But why do I get /usr/sbin/apachectl in which apachectl? to be continued
