Nginx – How to properly prevent 504 Gateway Time-out

fastcginginxPHPphp-fpm

I've an script that can run for about 15 min as it is a large data migration tool.

I have the problem that either if i set fastcgi_read_timeout 9900; it never times out or if i set it to less then it times out before my script finished running.

EDIT: I have taken away the fastcgi_read_timeout 9900; from nginx.conf and setted max_execution_time = 1300; in php.ini and I get a 504 Gateway Time-out now instead of looping forever.

How can I properly set that the page should be live until the script finishes executing?

Why do you want to run this in the foreground? While it's possible to hack at the config files long enough for you to get this behavior, it's a very fragile configuration. Is this something that's actually outputting useful information to the user as it goes? If not, this is almost certainly suited to a background task, rather then trying to run it in one request.

Even if this is outputting to the user, have you considered running it as a background task, and piping output to the user via some asynchronous method?

I found answer on my posting on the nginx forum - http://forum.nginx.org/read.php?2,127854

The answer, in my case, is to set:

request_terminate_timeout=30s

in php-fpm config (usually /etc/php5/fpm/php-fpm.conf)

Note, you can use values other than 30s also.

I used it to match my value in main php.ini file which is:

max_execution_time = 30

Thanks All. :-)

Centos – php is running scripts forever, but i have max_execution_time set to 30

The set_time_limit() function and the configuration directive max_execution_time only affect the execution time of the script itself. Any time spent on activity that happens outside the execution of the script such as system calls using system(), stream operations, database queries, etc. is not included when determining the maximum time that the script has been running. This is not true on Windows where the measured time is real.

You are probably falling on stream operations when using file_get_contents.

Try with:

while (1) { ;; }
