Install PHP APC with Nginx on Centos 6.2
Install latest apc:
# pecl install apc-3.1.10
Move your old apc.ini to a safe location:
# mv /etc/php.d/apc.ini /etc/php.d/apc.ini.old
Create a new /etc/php.d/apc.ini (content below):

Copy the apc.php to your domains root directory to see it in action
# cp /usr/share/doc/php-pecl-apc-3.1.10/apc.php /your domain root path/
If you are running Xcache which comes shipped with Centos 6.2 you will have a problem as the two dont get together. To remove Xcache simply use the following:
# yum remove php-xcache
Restart PHP-FPM
# /etc/init.d/php-fpm restart
