Apache 2.4 on CentOS 6

I installed Apache 2.4 on a min. installation of CentOS (in other words, this was a fresh Apache installation, not an upgrade from 2.2, there is no previous Apache on the box - I think...)

I'm a little green on this in general, but I see that Apache 2.4 got installed to:
/opt/rh/httpd24/root/var/www

(this was installed using repo http://repos.fedorapeople.org/repos/jkaluza/httpd24/epel-httpd24.repo)

and I need to stop/start/restart using command:
service httpd24-httpd {start|stop|restart}


The complication is:

1) I'm trying to install some modules, for example following the steps here for mod_pagespeed:
http://wpguru.co.uk/2014/03/how-to-install-apache-mod_pagespeed-on-centos-with-plesk/

it places its files here for example:
/etc/httpd/conf.d/pagespeed.conf


Should I be creating some kind of sym link to redirect attempts of accessing /etc/httpd/ to redirect to /opt/rh/httpd24/..<something>?

For example the Apache 2.6 conf file exists at /opt/rh/httpd24/root/etc/httpd/conf/httpd.conf

This is the file structure for the 2.4 httpd directory:

# ls -al /opt/rh/httpd24/root/etc/httpd
total 20
drwxr-xr-x.  5 root root 4096 May  1 10:57 .
drwxr-xr-x. 11 root root 4096 May  1 10:57 ..
drwxr-xr-x.  2 root root 4096 May  1 10:57 conf
drwxr-xr-x.  2 root root 4096 May  1 10:57 conf.d
drwxr-xr-x.  2 root root 4096 May  1 10:57 conf.modules.d
lrwxrwxrwx.  1 root root   34 May  1 10:57 logs -> /opt/rh/httpd24/root/var/log/httpd
lrwxrwxrwx.  1 root root   44 May  1 10:57 modules -> /opt/rh/httpd24/root/usr/lib64/httpd/modules
lrwxrwxrwx.  1 root root   34 May  1 10:57 run -> /opt/rh/httpd24/root/var/run/httpd



2) The other issue is I plan to install Plesk.  Has anyone installed Plesk on Apache 2.4? Does it detect this non-standard location of Apache?



Back to the module installation, the module isn't working and I don't know if I should copy the files over (but I don't want to keep having to do that)  or what the best practice is (create a sym link, but not sure what to link to what)

I do see some files here since Apache 2.2 wasn't installed I don't know if these files just come default with CentOS min build or where they came from.  The machine was built very recently (in the last month)



# ls -al /etc/httpd/conf
total 60
drwxr-xr-x. 2 root root  4096 May  1 11:12 .
drwxr-xr-x. 4 root root  4096 May  1 11:12 ..
-rw-r--r--. 1 root root 34418 Aug 15  2014 httpd.conf
-rw-r--r--. 1 root root 13139 Oct 16  2014 magic



Thanks in advance for any help or clarification.
