nginx的502错误网关与NodeBB

Question

连接到我的NodeBB安装使用我的域名时，我得到502网关 NodeBB的默认端口上运行（4567）

我nginx的似乎是正确配置（使用IP连接时）：http://puu.sh/mLI7U/0e03691d4c.png 我的nodebb似乎配置正确（当使用IP连接时）： http://puu.sh/mLI95/5fdafcaed9.png 我的A记录将IP指向我的VPS已正确配置。

这是我等/ nginx的/ conf.d/example.com.conf

server { 
listen 80; 

server_name sporklounge.com; 

location/{ 
    proxy_set_header X-Real-IP $remote_addr; 
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
    proxy_set_header Host $http_host; 
    proxy_set_header X-NginX-Proxy true; 

    proxy_pass http://127.0.0.1:4567/; 
    proxy_redirect off; 

    # Socket.IO Support 
    proxy_http_version 1.1; 
    proxy_set_header Upgrade $http_upgrade; 
    proxy_set_header Connection "upgrade"; 
} 

}

My NodeBB config.json 
{ 
    "url": "http://localhost:4567", 
    "secret": "25d0d6a2-0444-49dc-af0c-bd693f5829d8", 
    "database": "redis", 
    "redis": { 
     "host": "127.0.0.1", 
     "port": "6379", 
     "password": "", 
     "database": "0" 
    } 
} 

这是我无功/日志/ nginx的/ error.log中

所有帮助非常感谢，我将回答所有我可以帮助获得解决方案的问题，谢谢！

有一件事我看到的是，根据the docs，你url配置值应该是指向你NodeBB的全网络访问的地址。那将是sporklounge.com，而不是当前值。

也可能是后端有时只是响应缓慢。尝试在Nginx的这个值非常高的值，看看后台最终回应：

# For testing, allow very long response times. 
proxy_read_timeout 5m; 

此外，使用netstat来确认后端在端口4567上运行：

sudo netstat -nlp | grep ':4567' 

等待，答案可能就在你的日志，它给你的连接失败的原因：

（13：权限被拒绝），而连接到上游
