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:

  1. Set the fastcgi_param of PHP_VALUE to be the relevant setting in the nginx configuration: fastcgi_param PHP_VALUE "memory_limit = 128M";

  2. 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.

  • Run that application against a different PHP FPM pool.

    @growse, there is a missing semicolon at the end of fastcgi_param PHP_VALUE "memory_limit = 128M" else it gives an error. Thanks Feb 17, 2017 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(). Jan 3, 2020 at 21:41
