编译吗。。用这个

/usr/local/httpd/bin/apxs -i -a -c mod_rpaf-2.0.c

注意他有2个.c的2.0这个是for apache2.0的（文档太烂，我自己猜的，反正没2.0的编译不过去~~）

chmod 755 /usr/local/httpd/modules/mod_rpaf-2.0.so
[activating module `rpaf' in /usr/local/httpd/conf/httpd.conf]

貌似直接就搞上去了。。

RPAFenable On
# Enable reverse proxy add forward
RPAFproxy_ips 127.0.0.1 10.10.70.*

#实际测试中ip他不支持*这种通配符..所以还是写清楚你nginx的原始IP吧！
# which ips are forwarding requests to us
RPAFsethostname On
# let rpaf update vhost settings
# allows to have the same hostnames as in the “real”
# configuration for the forwarding Apache
RPAFheader X-REAL-IP
# Allows you to change which header mod_rpaf looks
# for when trying to find the ip the that is forwarding
# our requests

X-REAL-IP哪里来的呢？当然是nginx里面配置的~~

       set  $my_x_real_ip “”;
        if ($my_x_real_ip ~ “^$”) {
                set $my_x_real_ip $http_x_real_ip;
        }
        if ($http_x_real_ip ~ “^$”)  {
                set $my_x_real_ip $remote_addr;
        }        
        proxy_set_header    X-Real-IP $my_x_real_ip;

吧这个存成realIP.conf然后再nginx的conf里面每个server段include一下，就会多一个x-real-ip的header了

print_r($_SERVER);

[REMOTE_ADDR] => 192.168.105.47

你看，php已经能正常获取IP了！
