nginx反向代理、让代理节点记录客户端真实IP

环境：根据http://www.cnblogs.com/zzzhfo/p/6032095.html环境配置

在web01或web02上查看用户访问日志

先客户端访问

[root@web_backup /]# for n in {..} ;do curl www.test.com;sleep  ;done

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

查看日志

[root@web01 /]# tail -f /etc/httpd/logs/www.test.com.access_log

192.168.119.128 - - [/Sep/::: +] "GET / HTTP/1.0"

web端记录的都是nginx的IP

修改nignx负载均衡器的/usr/local/nginx/conf/nginx.conf；在location / 添加 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

worker_processes  ;

events {

    worker_connections  ;

}

http {

    include       mime.types;

    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  ;

upstream web_pools {

    server 192.168.119.130: weight=;

    server 192.168.119.133: weight=;

    server 192.168.119.131: weight=   backup;

}

    server {

        listen       ;

        server_name  www.test.com;

        location / {

            root   html;

            index  index.html index.htm;

            proxy_pass http://web_pools;

            proxy_set_header Host $host;

            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        }

        }

    }

重启nginx服务

[root@lb01 /]# nginx -s stop

[root@lb01 /]# nginx

[root@lb01 /]# netstat -anpt | grep nginx

tcp               0.0.0.0:                  0.0.0.0:*                   LISTEN      /nginx

在web01和web02上修改 /etc/httpd/conf/httpd.conf

[root@web01 /]# vim /etc/httpd/conf/httpd.conf

LogFormat "\"%{x-forwarded-for}i\" %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

<VirtualHost *:>

    DocumentRoot "/var/www/www"

    ServerName www.test.com

    ErrorLog "logs/www.test.com.error_log"

    CustomLog "logs/www.test.com.access_log" combined

</VirtualHost>

<VirtualHost *:>

    DocumentRoot "/var/www/bbs"

    ServerName bbs.test.com

    ErrorLog "logs/bbs.test.com.error_log"

    CustomLog "logs/bbs.test.com.access_log" combined

</VirtualHost>

[root@web01 /]# /etc/init.d/httpd restart

Stopping httpd:                                            [  OK  ]

Starting httpd:                                            [  OK  ]

[root@web02 /]# vim /etc/httpd/conf/httpd.conf

LogFormat "\"%{x-forwarded-for}i\" %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

<VirtualHost *:>

    DocumentRoot "/var/www/www"

    ServerName www.test.com

    ErrorLog "logs/www.test.com.error_log"

    CustomLog "logs/www.test.com.access_log" combined

</VirtualHost>

<VirtualHost *:>

    DocumentRoot "/var/www/bbs"

    ServerName bbs.test.com

    ErrorLog "logs/bbs.test.com.error_log"

    CustomLog "logs/bbs.test.com.access_log" combined

</VirtualHost>

测试：客户端访问

[root@web_backup /]# for n in {..} ;do curl www.test.com;sleep  ;done

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

<h1>www.test.com<h1/>

这是apahce的日志信息

如果web节点为nginx服务、则不需要修改、默认已经支持、只需在代理上添加：proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;即可

[root@lb02 /]# vim /usr/local/nginx/conf/nginx.conf

http {

    include       mime.types;

    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

    #                  '$status $body_bytes_sent "$http_referer" '

    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;
