Nginx 反向代理Tomcat服务器获取真实IP问题

1.nginx.conf 配置

修改 Server location配置

增加

proxy_set_header X-Real-IP $remote_addr; #保留代理之前的真实客户端ip
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;#记录代理过程

    server {
           listen   7777;
           server_name  192.168.10.8:7777;
           location / {
               root   /usr/local/web/dist;
               index  index.html index.htm;
            }
           location /unstructured/ {
                proxy_pass http://192.168.10.8:8080/unstructured/;
                proxy_set_header    X-Real-IP        $remote_addr;
                proxy_set_header    X-Forwarded-For  $proxy_add_x_forwarded_for;
    
            }
    }

2 修改 tomcat conf目录下server.xml配置

　　增加 Valve className="org.apache.catalina.valves.RemoteIpValve" 配置

       修改 Valve className="org.apache.catalina.valves.AccessLogValve" pattern中的配置%h  --->%{X-Real-IP}i 即可

			<Valve className="org.apache.catalina.valves.RemoteIpValve"   
                       remoteIpHeader="x-forwarded-for"
                       remoteIpProxiesHeader="x-forwarded-by" />
					   
			<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%{X-Real-IP}i %l %u %t "%r" %s %b" />

　　

通过以上两步的设置，我们在tomcat的日志文件 localhost_access_log.2019-07-02 可以看到记录了真实的ip地址，而非原先的nginx服务的ip。
