Newbie questions about nginx (moving from apache)

[pk899]

Hi 

sorry for english. 

i am on centos 64 bit server with cpanel and whm. 

i have apache 2.2.18 and there is heavy duty use of the following: 

1. mod rewrite 
2. mod geoip
3. mod security (with rules available in 2.6.0 for google safe browsing
checks etc)  
4. mod evasive 
5. php5 functionality with memcached + eaccelerator 

for #1, i see from threads on this phorum that some rewriting
functionality is possible. i also see that in 1.0.3 the #2 of geoip is
possible. 

but i am not sure about 3, 4 and 5. nginx does not support DDOS
protection right? also, will all the php5 modules work with pecl such as
memcached etc? 

in trying to set up nginx, i have problem getting php to work. mod fcgi
-- is there simple instruction about how to do, and how is the
performance when compared to apache+eaccelerator which opcode caches? 

because of this functionality, i don't want to move entire to nginx. 

so i am trying this: nginx run on localhost on port 81. apache is main
front server on port 80. all static content from images folder need to
pass to nginx. i am trying this code in apache: 


ProxyRequests       Off
ProxyPreserveHost   On
ProxyPass           /mysite/images    http://0.0.0.0:81/
ProxyPassReverse    /           http://0.0.0.0:81/


But this is not working. 

Nginx root folder is "/mysite/images". And when I type in browser
http://MYDOMAIN.COM:81 then I can see the nginx working fine. the images
are there. 

any idea about how i can make this setup work? 

or ideally, over time i want to move entirely to nginx. so would
appreciate some experienced thought or guidance. 

thanks
