nginx 设置反响代理实现nginx集群

ginx.conf：

worker_processes  1;

events {

    worker_connections  1024;

}

http {

    include       mime.types;

    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  65;

    upstream backend {

             #ip_hash;

             server 192.168.1.251;

             server 192.168.1.252;

             server 192.168.1.247;

         }

    server {

        listen       80;

        server_name  2;

        location / {

        #设置主机头和客户端真实地址，以便服务器获取客户端真实IP

             proxy_set_header Host $host;

             proxy_set_header X-Real-IP $remote_addr;

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

             #禁用缓存

             proxy_buffering off;

             #反向代理的地址

             proxy_pass http://backend;     

        }

    }

}

出现问题：http
{
         include             mime.types;
         default_type    application/octet-stream;
         source_charset GB2312;
         server_names_hash_bucket_size 256;
         client_header_buffer_size 256k;
         large_client_header_buffers 4 256k;

         #size limits
         client_max_body_size             50m;
         client_body_buffer_size        256k;
         client_header_timeout     3m;
         client_body_timeout 3m;
         send_timeout             3m;
#参数都有所调整.目的是解决代理过程中出现的一些502 499错误     
         sendfile on;
         tcp_nopush         on;
         keepalive_timeout 120; #参数加大,以解决做代理时502错误
         tcp_nodelay on;
        
         include                    vhosts/upstream.conf;
         include                    vhosts/bbs.linuxtone.conf;
