questions/concerns to be addressed:
	compile options:
		how to find info on config options, what they mean, etc. (need links)
		what is the difference running php as a cgi?
		path to executables?
		modules @ apache: how to compile, use, etc.
		`export install=/usr/local/`, then test it with `echo $install`
		

compile process:
	-> cd to source directory
	-> `./configure [--with-options=xyz]` (check for system libraries, writes the make file) (as user)
	-> `make` (as user)
	-> `make test`
	-> `make install` (as root)
	-> `make clean`
	-> note the .config.cache hidden file, and the config.log file
	-> for security, run `configure`, `make`, `make test`, etc. as regular user - then run `make install` as root 
	    (must have elevated privileges to copy binaries to their final home)
	-> make sure you have gcc (the gnu compiler) and gcc-c++ (the gnu c++ compiler) installed
	`yum -y install gcc gcc-c++`


misc. notes:

compile apache & mysql first
compile php last, because it links/loads modules that work with/against apache/mysql

why compile?
	-> note difference between installing per rpm and compiling
	-> compile is specific to local hardware
	-> circumvent the actions of others (security or configuration)
	-> can custom compile: strip out for lighter binary, or add options that aren't usually available
	-> latest features
	-> bug fixes
	-> advanced development may need a custom install
	-> custom patches

pre-build:
	-> need gcc (the GNU c compiler)
	-> `yum install ncurses ncurses-devel gcc gcc-devel gcc-c++ kernel-headers kernel-devel`
	-> `mkdir /usr/local/src/{apache,php,mysql,phpmyadmin,webmin}`
	-> set prefix location variable: `export install=/usr/local`


//---------------------------------------------------------//
//--------- apache ---------//
go to current apache configuration, look for /server-status & /server-info
perform `rpm -qa | grep httpd`

download the source {/usr/local/src/apache}
	`cd /usr/local/src/apache`
	unzip: `tar xvzf xyz`
	`./configure --prefix=$install/httpd/
				--enable-rewrite
				--enable-so
				[--enable-maintainer-mode]`
	make (as user)
	make install


note config file: $install/httpd/conf/httpd.conf

excellent source of information for building/compiling apache, including modules and customizations: http://www.faqs.org/docs/apache-compile/intro.html


//---------------------------------------------------------//
//--------- mysql ---------//
download the source {/usr/local/src/mysql}
	`cd /usr/local/src/mysql`
	unzip: `tar xvzf xyz`
	`./configure --prefix=$install/mysql
	`make`
	`make install`

Building MySQL threw a configure error "No curses/termcap library found"...
`yum -y install termcap libtermcap libtermcap-devel ncurses ncurses-devel php-ncurses`

MySQL has lots of config options, the above is the bare minimum; it's possible to do a lot of path tweaking.

//---------------------------------------------------------//
//--------- php ---------//
download the source {/usr/local/src/php}
	`cd /usr/local/src/php`
	unzip: `tar xvzf xyz`
	
yum -y install libxml2-devel

`./configure --prefix=$install
			--with-config-file-path=$install
			--with-apxs2=$install/bin/apxs
			--enable-debug 	{WHAT DOES PHP DEBUGGING DO?}


./configure --prefix=$install/php --with-config-file-path=$install/php --with-apxs2=$install/httpd/bin/apxs --enable-debug

“make install”  will alter the httpd.conf file.
It's important to also add the following:
  AddType application/x-httpd-php .php (and whatever other files you want parsed)
Then copy php.ini-dist from your source folder to $install/php/php.ini
