Nginx配置WebSocket

Nginx配置WebSocket反向代理

问题描述

目前项目中需要使用到WebSocket来进行通讯,所以就写了个Nginx反向代理WebSocket的配置文件.

很简单,但是很有效,能够横向扩展WebSocket服务端

先直接展示配置文件,如下(使用的话直接复制,然后改改ip和port即可)

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

upstream wsbackend{
    server ip1:port1;
    server ip2:port2;
    keepalive 1000;
}

server {

    listen 20038;

    location /{

        proxy_http_version 1.1;
        proxy_pass http://wsbackend;
        proxy_redirect              off;
        proxy_set_header            Host $host;
        proxy_set_header            X-Real-IP $remote_addr;
        proxy_read_timeout          3600s;
        proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
    }
}

会用了还需要理解(厚积薄发,不要让曾经的努力白费)

首先:

map $http_upgrad
