Nginx or PHP FPM ignores memory_limit in php.ini

Question

Server info: Ubuntu Server, Nginx, PHP FPM

in /etc/php5/fpm/php.ini I have: memory_limit = 512M in /etc/php5/fpm/php-fpm.conf I have: php_admin_value[memory_limit] = 512M

php_value[memory_limit] = 512M 

My phpinfo looks like:

The problem is when i change upload_max_filesize size then the phpinfo will show the new value, but when I change memory_limit then nothing changes. I guess in somewhere the memory_limit is overwrited. But i cannot find it. Can anyone help me?

Answer 1

In /etc/php5/fpm/php-fpm.conf I have php_admin_value[memory_limit] = 512M

This works for me.

Answer 2

The problem may be in fpm the process duplication, even you change your /etc/php5/fpm/php.ini it was not effect.

• Stop php5-fpm with (ubuntu): sudo service php5-fpm stop
• check that no more fpm processes: sudo ps ax | grep fpm
• if any kill it all with: sudo kill -9 pid
• be sure that you kill all fpm processes
• restart: sudo service php5-fpm restart
