php-fpm:
request_terminate_timeout = 30
php.ini:
max_execution_time = 30

request_terminate_timeout is suitable for when max_execution_time cannot terminate the script for some reason, this php-fpm request will be killed.

The execution time of web request PHP is controlled by two aspects, one is max_execution_time of php.ini (it should be noted that sleep, the time for http request to wait for response is not counted, here is the real execution time) , the other is the php-fpm request_terminate_timeout setting, which counts n seconds since the request started.

will also terminate the Worker process that executes the script. Therefore, Nginx will find that the connection to communicate with itself is broken, and will return a 502 error to the client.
