Nginx反向代理导致504网关超时

Question

我使用Nginx作为反向代理，它接收请求，然后执行proxy_pass以从运行在8001端口上的上游服务器获得实际的web应用程序。

如果我转到mywebsite.com或执行wget，我会在60秒后获得504网关超时...但是，如果我加载mywebsite.com:8001，应用程序将按预期加载！

server {
    listen   80;
    server_name mywebsite.com;

    root /home/user/public_html/mywebsite.com/public;

    access_log /home/user/public_html/mywebsite.com/log/access.log upstreamlog;
    error_log /home/user/public_html/mywebsite.com/log/error.log;

    location / {
        proxy_pass http://xxx.xxx.xxx.xxx:8001;
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
} 

和Nginx错误日志的输出：

2014/06/27 13:10:58 [error] 31406#0: *1 upstream timed out (110: Connection timed out) while connecting to upstream, client: xxx.xx.xxx.xxx, server: mywebsite.com, request: "GET / HTTP/1.1", upstream: "http://xxx.xxx.xxx.xxx:8001/", host: "mywebsite.com"

Answer 1

可能可以再增加几行，以增加上游的超时时间。下面的示例将超时设置为300秒：

proxy_connect_timeout       300;
proxy_send_timeout          300;
proxy_read_timeout          300;
send_timeout                300;
