Question

我有一个默认的 Laravel应用程序在端口80上运行。它使用PHP 7的默认设置。现在，我想添加另一个通常运行在端口3000上的nodejs应用程序，并在Nginx上从端口8000到3000使用反向代理。但是事实证明这是502错误的网关。这是我的pm2状态

 Use `pm2 show <id|name>` to get more details about an app

我怀疑502的真正原因是因为用户是root用户，所以我将所有js文件所有权更改为

我已经在firewall-cmd上公开了8000端口，并将其添加到/etc/service中。但这一切都失败了。

这是nginx默认配置(/etc/nginx/nginx.conf)

供您参考，此VPS尚未设置域名。因此，它们全部在常规http上运行。

这是8000端口的conf

upstream fam-app {
    server <VPS_IP>:3000;
}

server {
    listen 8000;
    location / {
            proxy_set_header X-NginX-Proxy true;
        proxy_pass http://fam-app/;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_redirect off;
        proxy_max_temp_file_size 0;
        proxy_read_timeout 240s;

    }
}

大多数解决方案都显示了如何在Ubuntu上运行pm2和nginx，但对Centos 7却知之甚少。
