4.7.1版本 此版本长链接端口修改了 具体是这样改?

此版本长链接端口修改为50001，50002，50003，重启长链接之前需要修改反向代理端口

    location /notice {
        proxy_pass http://127.0.0.1:50001/;  
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header X-real-ip $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
    }
    location /msg {
        proxy_pass http://127.0.0.1:50002/;  
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header X-real-ip $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
    }

这样的? 50003不用管是吧? 感谢
