Here is the start of a configuration that will pass the 50 user test from loadimpact.com with no sweat with a heavy php application like Drupal 7. This is from a CentOS base install and will not work for SSL or VirtualHosts as is. I will add that later. I want the community to try this out and let me know what they think in general.

The idea is that httpd-light acts as lighttpd or nginx and servers only static content. It directs php requests to the httpd config.

Here it is!:

#Install the LAMP components
yum -y install httpd mysql mysql-server php53 php53-gd php53-pdo php53-mbstring php53-xml php53-mysql

#Create init.d script for httpd-light
cp /etc/init.d/httpd /etc/init.d/httpd-light
sed -i 's/httpd Startup/httpd-light Startup/g' /etc/init.d/httpd-light
sed -i 's/processname: httpd/processname: httpd-light/g' /etc/init.d/httpd-light
sed -i 's,/etc/httpd/conf/httpd.conf,/etc/httpd-light/conf/httpd.co nf,g' /etc/init.d/httpd-light
sed -i 's,/etc/sysconfig/httpd,/etc/sysconfig/httpd-light,g' /etc/init.d/httpd-light
sed -i 's,/var/run/httpd.pid,/var/run/httpd-light.pid,g' /etc/init.d/httpd-light
sed -i 's,prog=httpd,prog=httpd-light,g' /etc/init.d/httpd-light
sed -i 's,/var/lock/subsys/httpd,/var/lock/subsys/httpd-light,g' /etc/init.d/httpd-light
sed -i '/STOP_TIMEOUT=/ a\
OPTIONS="-f /etc/httpd-light/conf/httpd.conf"' /etc/init.d/httpd-light

#Create httpd-light configuration directory and configure httpd-light
cp -r /etc/httpd/ /etc/httpd-light
sed -i 's,ServerRoot "/etc/httpd",ServerRoot "/etc/httpd-light",g' /etc/httpd-light/conf/httpd.conf
sed -i 's,PidFile run/httpd.pid,PidFile run/httpd-light.pid,g' /etc/httpd-light/conf/httpd.conf

#Create new file /etc/httpd-light/conf.d/reverseproxy.conf
echo LoadModule proxy_module modules/mod_proxy.so> /etc/httpd-light/conf.d/reverseproxy.conf
echo ProxyPreserveHost on>> /etc/httpd-light/conf.d/reverseproxy.conf
echo ProxyPassReverse / http://127.0.0.1:8080/>> /etc/httpd-light/conf.d/reverseproxy.conf
echo RewriteEngine on>> /etc/httpd-light/conf.d/reverseproxy.conf
echo RewriteCond %{REQUEST_URI} .*\\.$php$$>> /etc/httpd-light/conf.d/reverseproxy.conf
echo RewriteRule ^/$.*$ http://127.0.0.1:8080/\$1 [P]>> /etc/httpd-light/conf.d/reverseproxy.conf

#No need for php on the httpd-light
rm -f /etc/httpd-light/conf.d/php.conf

#Configure httpd config
sed -i 's/Listen 80/Listen 127.0.0.1:8080/g' /etc/httpd/conf/httpd.conf

#Configure httpd for 10 max clients (uses about X MB)
sed -i 's/ServerLimit 256/ServerLimit 10/g' /etc/httpd/conf/httpd.conf
sed -i 's/MaxClients 256/MaxClients 10/g' /etc/httpd/conf/httpd.conf

#invalidate the worker config in the main httpd.conf for httpd-light
sed -i 's/<IfModule worker.c>/<IfModule worker-old.c>/g' /etc/httpd-light/conf/httpd.conf

#Configure httpd-light for worker max clients (uses about X MB)
sed 's,#HTTPD=/usr/sbin/httpd.worker,HTTPD=/usr/sbin/httpd.worke r,g' /etc/sysconfig/httpd > /etc/sysconfig/httpd-light

echo "<IfModule worker.c>
ThreadLimit 1024
StartServers 2
MaxClients 2048
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 1024
MaxRequestsPerChild 0
</IfModule>"> /etc/httpd-light/conf.d/worker.conf

chkconfig httpd on
chkconfig httpd-light on
chkconfig mysqld on

service httpd start
service httpd-light start
service mysqld start
