• 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; 

    }
