nginx中的超时设置

参考博文： nginx中的超时设置

nginx使用proxy模块时，默认的读取超时时间是60s。

1. send_timeout

syntax: send_timeout the time

default: send_timeout 60

context: http, server, location

Directive assigns response timeout to client. Timeout is established not on entire transfer of answer, but only between two operations of reading, if after this time client will take nothing, then nginx is shutting down the connection.

 2. 负载均衡配置时的2个参数：fail_timeout和max_fails

   这2个参数一起配合，来控制nginx怎样认为upstream中的某个server是失效的当在fail_timeout的时间内，某个server连接失败了max_fails次，则nginx会认为该server不工作了。同时，在接下来的 fail_timeout时间内，nginx不再将请求分发给失效的server。
个人认为，nginx不应该把这2个时间用同一个参数fail_timeout来控制，要是能再增加一个fail_time，来控制接下来的多长时间内，不再使用down掉的server就更好了~
如果不设置这2个参数，fail_timeout默认为10s，max_fails默认为1。就是说，只要某个server失效一次，则在接下来的10s内，就不会分发请求到该server上

3. proxy模块的 proxy_connect_timeout

syntax: proxy_connect_timeout timeout_in_seconds

context: http, server, location

This directive assigns a timeout for the connection to the proxyserver. This is not the time until the server returns the pages, this is the proxy_read_timeout statement. If your proxyserver is up, but hanging (e.g. it does not have enough threads to process your request so it puts you in the pool of connections to deal with later), then this statement will not help as the connection to the server has been made. It is necessary to keep in mind that this time out cannot be more than 75 seconds.

4. proxy模块的proxy_read_timeout

syntax: proxy_read_timeout the_time

default: proxy_read_timeout 60

context: http, server, location

This directive sets the read timeout for the response of the proxied server. It determines how long NGINX will wait to get the response to a request. The timeout is established not for entire response, but only between two operations of reading.

In contrast to proxy_connect_timeout, this timeout will catch a server that puts you in it‘s connection pool but does not respond to you with anything beyond that. Be careful though not to set this too low, as your proxy server might take a longer time to respond to requests on purpose (e.g. when serving you a report page that takes some time to compute). You are able though to have a different setting per location, which enables you to have a higher proxy_read_timeout for the report page‘s location.

If the proxied server nothing will communicate after this time, then nginx is shut connection.
