- Internet -> Nginx -> Apache
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
