前端Nginx，后端Apache获取用户真实IP地址

最近在将Apache-2.2和Apache-2.4添加到《lnmp一键安装包》中，Nginx作为前端，Apache作为后端的情况下，Apache只能获取到Nginx前端的ip地址（127.0.0.1），而无法获取到用户的真实ip地址，在这种情况下，后端是Apache如何获取用户真实IP地址？

Nginx配置如下：

location /
{

try_files $uri @apache;

}

 

location @apache
{

internal;

proxy_pass http://127.0.0.1:8080;

include proxy.conf;

}

 

location ~
.*\.(php|php5)?$ {

proxy_pass http://127.0.0.1:8080;

include proxy.conf;

}

proxy_connect_timeout 300s;

proxy_send_timeout 900;

proxy_read_timeout 900;

proxy_buffer_size 32k;

proxy_buffers 4
64k;

proxy_busy_buffers_size 128k;

proxy_redirect off;

proxy_hide_header Vary;

proxy_set_header Accept–Encoding
”;

proxy_set_header Referer $http_referer;

proxy_set_header Cookie $http_cookie;

proxy_set_header Host $host;

proxy_set_header X–Real–IP $remote_addr;

proxy_set_header X–Forwarded–For $proxy_add_x_forwarded_for;

获取真实IP地址有Apache有2个模块：
mod_rpaf：Apache-2.2支持；Apache-2.4不支持。网上教程很多
mod_remoteip：Apache-2.4自带模块；Apache-2.2支持；推荐

Apache-2.2.25
mod_rpaf模块

wget http://stderr.net/apache/rpaf/download/mod_rpaf–0.6.tar.gz

tar –xzvf mod_rpaf–0.6.tar.gz

cd mod_rpaf–0.6/

/usr/local/apache/bin/apxs –i –c –n mod_rpaf–2.0.slo mod_rpaf–2.0.c

添加Apache配置

vi /usr/local/apache/conf/httpd.conf

Include conf/extra/httpd–rpaf.conf

vi /usr/local/apache/conf/extra/httpd-rpaf.conf

LoadModule rpaf_module modules/mod_rpaf–2.0.so

RPAFenable
On

RPAFsethostname
On

RPAFproxy_ips
127.0.0.1
10.8.0.110
# 代理服务器的ip地址（记得做相应修改）

RPAFheader X–Forwarded–For

备注：RPAFproxy_ips后面添加代理服务器的ip地址,有几个填几个
测试

# /usr/local/apache/bin/apachectl -t

# /usr/local/apache/bin/apachectl restart

# 看日志

mod_remoteip
Apache-2.2下配置mod_remoteip如下：
安装

wget https://github.com/ttkzw/mod_remoteip–httpd22/raw/master/mod_remoteip.c

/usr/local/apache/bin/apxs –i –c –n mod_remoteip.so mod_remoteip.c

修改配置文件：

vi /usr/local/apache/conf/httpd.conf

Include conf/extra/httpd–remoteip.conf

vi /usr/local/apache/conf/extra/httpd–remoteip.conf

LoadModule remoteip_module modules/mod_remoteip.so

RemoteIPHeader X–Forwarded–For

RemoteIPInternalProxy
127.0.0.1

测试：

# /usr/local/apache/bin/apachectl -t

# /usr/local/apache/bin/apachectl restart

# 看日志

Apache-2.4配置mod_remoteip除了上面（自带mod_remoteip模块不需要安装），还需要修改日志格式（折腾很久）

LogFormat
“%h %a %l %u %t \”%r\” %>s %b \”%{Referer}i\” \”%{User-Agent}i\”” combined

LogFormat
“%h %a %l %u %t \”%r\” %>s %b” common

LogFormat
“%h %l %u %t \”%r\” %>s %b \”%{Referer}i\” \”%{User-Agent}i\” %I %O” combinedi

在日志格式中加上%a
