Question

我正在使用nginx监听端口8080并在端口8081,8081,8083和8084上的四个龙卷风实例上使用nginx.conf进行平衡。如何强制nginx监听另一个端口8090并在端口8091,8092,8093和8094上进行平衡？在[808 *]上运行的龙卷风实例与[809 *]

不同

8080 balance on [8081, 8082, 8083, 8084]
8090 balance on [8091, 8092, 8093, 8094]

有nginx.conf

worker_processes 16;

error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;


#master_process off;
daemon off;

events {
    worker_connections 1024;
    use epoll;
}

http {
    charset utf-8;

    # Enumerate all the Tornado servers here
    upstream frontends {
        server 127.0.0.1:8081;
        server 127.0.0.1:8082;
        server 127.0.0.1:8083;
        server 127.0.0.1:8084;
    }

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    proxy_buffering off;
    proxy_buffers 4 512k;
    proxy_buffer_size 512k;

    access_log /var/log/nginx/access.log;

    #keepalive_timeout 65;
    #proxy_read_timeout 200;

    keepalive_timeout 600;
    proxy_connect_timeout       600;
    proxy_send_timeout          600;
    proxy_read_timeout          600;
    send_timeout                600;
    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    gzip on;
    gzip_min_length 1000;
    gzip_proxied any;
    gzip_types text/html text/plain text/css application/javascript application/x-javascript text/javascript text/xml application/xml;

    # Only retry if there was a communication error, not a timeout
    # on the Tornado server (to avoid propagating "queries of death"
    # to all frontends)
    proxy_next_upstream off;

    server {
        listen 8080;
        server_name localhost;

        location /
        {
            access_log off;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }

        # Allow file uploads
        client_max_body_size 50M;


        location ^~ /static/ {
            root /home/server/;
            if ($query_string) {
                expires max;
            }
        }

    }
}

您需要两个upstream和两个server块。像这样的东西（其他选项像以前一样填写）：

http {
  upstream eighties {
    server http://127.0.0.1:8081;
    server http://127.0.0.1:8082;
  }
  upstream nineties {
    server http://127.0.0.1:8091;
    server http://127.0.0.1:8092;
  }
  server {
    listen 8080;
    location / {
      proxy_pass http://eighties;
    }
  }
  server {
    listen 8090;
    location / {
      proxy_pass http://nineties;
    }
  }
}

如何让不同端口的nginx平衡到不同的端口？
