问题
I recently upgraded to PHP 7.
I placed this in /etc/php.d/opcache.ini
opcache.file_cache = /var/www/html/.opcache
opcache.file_cache_only = 1
and created the directory (as root)
When I visit the site there is nothing created in the .opcache folder
a phpinfo(); reflects the changes I made in opcache.ini
How can I get PHP 7 Opcache working at optimal performance with WordPress?
update The problem was witch folder permissions. 'Ale sure the Apache can write to it.
What are the optimal settings for it? Security and speed wise?
回答1:
I fixed this by making sure apache get write to the folders I created. Once that was done restarting httpd made it work.
