php-fcgi The execution time setting method of PHP

Yesterday, a program needs to export 500 data, the results found that 150 is, Nginx reported 504 Gateway timeout error, the original php-fcgi under the setting execution time differs from the ISAPI

In general, set the time when PHP script execution times out

One, in the php.ini inside set

max_execution_time = 1800;
Second, through the PHP ini_set function set

Ini_set ("Max_execution_time", "1800");
Third, through the Set_time_limit function set

Set_time_limit (1800);

Yesterday, a program needs to export 500 data, the results found that 150 is, Nginx reported 504 Gateway timeout error

It was observed that time-outs of about 30 seconds were found, and the execution times in php.ini were 300 seconds:

Max_execution_time = 300

Re-check the relevant configuration of nginx, no fruit.

I wrote a test page for PHP and then measured it.

Echo ' AAA '; Set_time_limit (0); Sleep (a); Echo ' AA ';

Still timeout, you can determine that the Set_time_limit function is not effective.

Re-check the configuration of php-fcgi php-fpm.conf, the bottom of this setup suspect a problem

<value name= "Request_terminate_timeout" >30s</VALUE>

Check official documents: Http://php-fpm.org/wiki/Configuration_File

 for  for Default

The main idea is that PHP in Set_time_limit set the time if PHP has not finished, then go to the configuration here, that is, request_terminate_timeout=30 seconds.
First change this parameter and PHP in the same set_time_limit value, are 300 seconds, not yet, do not understand why, if the master know please enlighten.

Finally the Request_terminate_timeout closed, the program can be executed normally, problem solving

<value name= "Request_terminate_timeout" >0s</VALUE>

Add: If the Nginx server on the front-end uses upstream load balancing, the following parameters in that load balancer configuration need to be modified accordingly

Proxy_connect_timeout       300s;  Proxy_send_timeout          300s;   Proxy_read_timeout
