Have postavil packages php5-fpm and php-apc from the official repository ubuntu 10.10 configured apc:
/etc/php5/conf.d/apc.iniextension=apc.so
apc.enabled=1
apc.shm_size=128M
After restarting php5-fpm on the website error:
Fatal error: Call to undefined function apc_exists() in /var/www/.../application/models/user_model.php on line 271
phpinfo(); using the fpm said that the apc module is loaded.
Has anyone encountered a similar problem?
