Nginx在60秒后完全超时

我在后端(带有Puma的Rails)上有一个app服务器绑定到unix套接字 这是nginx配置的相关部分

location /live/ {
 proxy_pass http://app; # match the name of upstream directive which is defined above
 proxy_set_header Host $host;
 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 proxy_redirect off;
 proxy_set_header Connection 'Upgrade';
 proxy_http_version 1.1;
 chunked_transfer_encoding off;
 send_timeout 300;
 proxy_send_timeout 300;
 keepalive_timeout 7200;
}

SSE事件来自/ live /,因此我调整了ngix配置来处理对此路由的所有请求。

问题是连接在60秒后完全关闭。这是我在响应标题中看到的内容

Cache-Control:no-cache
Connection:keep-alive
Content-Type:text/event-stream
Date:Mon, 04 Nov 2013 13:41:52 GMT
Server:nginx
X-Content-Type-Options:nosniff
X-Frame-Options:SAMEORIGIN
X-Request-Id:7065a7bc-3450-4fe2-b60c-33dfa8d41951
X-Runtime:0.010852
X-UA-Compatible:chrome=1
X-XSS-Protection:1; mode=block

所以似乎nginx将初始响应设置为关闭。为什么 keepalive_timeout 在这里不起作用。

在nginx error.log中我看到了

2013/11/04 13:42:52 [error] 3689#0: *9 upstream timed out (110: Connection timed out)   while reading upstream, client: ......., server: myapp.com, request: "GET /live/events HTTP/1.1", upstream: "http://unix:/home/ubuntu/myapp/shared/sockets/puma.sock:/live/events", host: "myapp.com"

万一其他人遇到Nginx + Puma + Rails的Timeout错误,Nginx中的以下配置应该将超时时间增加到605秒(10分5秒):

我认为您应该检查proxy_connect_timeout(默认60秒;))和proxy_read_timeout(默认60秒),这可能会导致此错误。您可以在这里找到文档:
