Question

我无法让nginx与ip_hash模块中启用的upstream进行负载均衡。当我删除它负载平衡工作，但我需要粘性会话。我做错了什么？

map $http_upgrade $connection_upgrade {
     default upgrade;
     ''      close;
}

upstream backend {
    ip_hash;
    server localhost:3900 max_fails=3 fail_timeout=5s;
    server localhost:3901 max_fails=3 fail_timeout=5s;
}

# Only retry if there was a communication error, not a timeout.
proxy_next_upstream error;

server {
    server_name  localhost;
    listen 8300;
    access_log  /var/log/nginx/myapp.access.log;

    # static file
    location /assets/ {
        root /location/to/statics/;
        autoindex off;
    }

    # sockjs
    location / {
        proxy_pass http://backend;
        proxy_http_version 1.1;
        proxy_redirect off;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

我从一台计算机上运行所有测试，因此所有连接都具有相同的IP地址，并且由于粘性会话而被放到同一台服务器上。

Nginx ip_hash不平衡连接
