nginx多层反向代理获取客户端真实ip

访问路径：

用户 --> www.chinasoft.cn(nginx反向代理) --> www.chinasoft.com(nginx反向代理) --> python服务端程序

经过多层代理

第一层代理：

nginx多层代理获取客户端的真实ip总结：

、编译Nginx时，添加http_realip_module模块

、在nginx.conf文件中

proxy_pass  xxxxxx添加下面三行

proxy_set_header   Host             $host;

proxy_set_header   X-Real-IP        $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

、在每一层nginx日志中的打印的"$http_x_forwarded_for"就是真实客户端的ip地址。

、后台服务器获取真实的客户端ip地址：

headers中的X-Forwarded-For选项中逗号前第一个ip就是真实客户端ip

日志中获取真实ip:  $http_x_forwarded_for 就是获取真实ip的变量

log_format main  '$remote_addr $http_x_forwarded_for - - [$time_local] - - "$request" $status $body_bytes_sent "$http_referer" "$http_user_agent" $request_time ';

# more /usr/local/nginx/conf/rewrite.d/chinsoft.com.conf
if ($request_uri ~ ^/(.*)/(index|indice).(html)) { rewrite ^/(.*)/(index|indice).(html) /$1 permanent;}
