前端Nginx，后端Apache获取用户真实IP地址

admin

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：

1. location / {
   
2.         try_files $uri @apache;
   
3.         }
   
4. 
   
5. location @apache {
   
6.         internal;
   
7.         proxy_pass http://127.0.0.1:8080;
   
8.         include proxy.conf;
   
9.         }
   
10. 
    
11. location ~ .*\.(php|php5)?$  {
    
12.         proxy_pass http://127.0.0.1:8080;
    
13.         include proxy.conf;
    
14.         }

复制代码

1. proxy_connect_timeout 300s;
   
2. proxy_send_timeout 900;
   
3. proxy_read_timeout 900;
   
4. proxy_buffer_size 32k;
   
5. proxy_buffers 4 64k;
   
6. proxy_busy_buffers_size 128k;
   
7. proxy_redirect off;
   
8. proxy_hide_header Vary;
   
9. proxy_set_header Accept-Encoding '';
   
10. proxy_set_header Referer $http_referer;
    
11. proxy_set_header Cookie $http_cookie;
    
12. proxy_set_header Host $host;
    
13. proxy_set_header X-Real-IP $remote_addr;
    
14. 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

1. wget http://stderr.net/apache/rpaf/download/mod_rpaf-0.6.tar.gz
   
2. tar -xzvf mod_rpaf-0.6.tar.gz
   
3. cd mod_rpaf-0.6/
   
4. /usr/local/apache/bin/apxs  -i -c -n mod_rpaf-2.0.slo mod_rpaf-2.0.c

复制代码

添加Apache配置

1. vi  /usr/local/apache/conf/httpd.conf
   
2. Include conf/extra/httpd-rpaf.conf
   
3. vi /usr/local/apache/conf/extra/httpd-rpaf.conf
   
4. 
   
5. LoadModule rpaf_module        modules/mod_rpaf-2.0.so
   
6. RPAFenable On
   
7. RPAFsethostname On
   
8. 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）
   
9. RPAFheader X-Forwarded-For

复制代码

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

1. # /usr/local/apache/bin/apachectl -t
   
2. # /usr/local/apache/bin/apachectl restart
   
3. # 看日志

复制代码

mod_remoteip
Apache-2.2下配置mod_remoteip如下：
安装

1. wget https://github.com/ttkzw/mod_remoteip-httpd22/raw/master/mod_remoteip.c
   
2. /usr/local/apache/bin/apxs -i -c -n mod_remoteip.so mod_remoteip.c

复制代码

修改配置文件：

1. vi /usr/local/apache/conf/httpd.conf
   
2. Include conf/extra/httpd-remoteip.conf
   
3. vi /usr/local/apache/conf/extra/httpd-remoteip.conf
   
4. LoadModule remoteip_module modules/mod_remoteip.so
   
5. RemoteIPHeader X-Forwarded-For
   
6. RemoteIPInternalProxy 127.0.0.1

复制代码

测试：

1. # /usr/local/apache/bin/apachectl -t
   
2. # /usr/local/apache/bin/apachectl restart
   
3. # 看日志

复制代码

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）

1. LogFormat "%h %a %l %u %t "%r" %>s %b "%{Referer}i" "%{User-Agent}i"" combined
   
2. LogFormat "%h %a %l %u %t "%r" %>s %b" common
   
3. LogFormat "%h %l %u %t "%r" %>s %b "%{Referer}i" "%{User-Agent}i" %I %O" combinedi

复制代码

在日志格式中加上%a
