This might be a dumb question, but anyway here it goes.
From the below link I could see that default config link for apache httpd2 is at "/usr/local/apache2/conf/httpd.conf" https://wiki.apache.org/httpd/DistrosDefaultLayout
how ever when I install httpd using yum on centos 6 and 7 config files seems to be at "/etc/httpd/conf/httpd.conf
Why doesn't yum install it to the location defined on the default distribution layout.
