Nginx反向代理webscoket

在nginx/config/nginx.conf中添加下面配置

map $http_upgrade $connection_upgrade{
    default upgrade;
    '' close;
}
upstream web{
    server 域名;
}
upstream websocket{
    server X.x.x.x:8888;
}
upstream websocket1{
    server x.x.x.x:7777;
}
server{
    listen 443;
    server_name 域名;
    charset utf-8;
    ssl on;
    ssl_certificate    证书;
    ssl_certificate_key ;

    ssl_session_timeout 5m;
    ssl_session_cache shared:SSL:50m;
    ssl_protocols TLSV1.1 TLSV1.2 SSLv2 SSLv3;
    ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
    ssl_prefer_server_ciphers on;

    #websocket代理地址
    location /wss {
        proxy_pass http://websocket;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
    }
 location /jz {
        proxy_pass http://websocket1;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
    }
    #原来的https功能代理回原来的地址
    location /{
        proxy_pass http://web;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        add_header Access-Control-Allow-Origin *;
    }
}

在nginx/sbin/中执行

./nginx -c nginx.conf
./nginx -s reload

网站后端使用workman监听websocket 端口

可以监听不同的端口
