- ; The timeout for serving a single request after which the worker process would
- ; Be killed. This option should is used when the ' max_execution_time ' ini option
- ; Does not a stop script execution for some reason. A value of ' 0′means ' off '.
- ; Available units:s (econds) (default), M (inutes), H (ours), or D (ays)
- ; Default value:0
- Request_terminate_timeout = 0
Because this parameter will directly kill the PHP process, and then restart the PHP process, so that the front-end Nginx will return 104:connection reset by peer. This process is very slow, the overall feeling is that the website is very card.
The above describes the Nginx 502 error collection, including the nginx,502 aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
