nginx + php-fpm: how to specify memory limit for an application

Question

With apache+php_mod it was as easy as putting:

php_value      memory_limit        128M

into application vhost.

How can I do something like this for nginx+php-fpm?

You've got a couple of options. You can either:

Set the fastcgi_param of PHP_VALUE to be the relevant setting in the nginx configuration: fastcgi_param PHP_VALUE "memory_limit = 128M";
Set it via the php_value setting in the FPM pool configuration file. Something like php_value[memory_limit] = 128M. Use php_admin_value if you don't want the setting to be overridable via ini_set.

In the second case how to do that specifically for a given application/domain. – clime Apr 17 '13 at 12:49
Run that application against a different PHP FPM pool. – growse Apr 17 '13 at 14:09

Don't forget to restart nginx and php-fpm after you make these changes. – Jaspal Singh Feb 17 '17 at 18:29

@growse, there is a missing semicolon at the end of fastcgi_param PHP_VALUE "memory_limit = 128M" else it gives an error. Thanks – Jaspal Singh Feb 17 '17 at 18:32

I had to use `php_admin_value[memory_limit]` instead of `php_value[memory_limit]`. The difference between both, according to the documentation, is that the first cannot be overridden by `*.ini` files or `ini_set()`. – Gwyneth Llewelyn Jan 03 '20 at 21:41
