问题
ive recently activated opcache but it doesn't appear to be working. It's confirmed activated via phpinfo()
As you can see 0 hits 1 miss 1 cached script (opcached gui)
What am I missing?
Server is a Linux server centos 6.5 vps PHP 5.5

回答1:
This looks like you are using cgi rather than mod_php5. The shared memory area (SMA) is used for both, but it only persists request-to-request for the latter.

I had this issue on a WHM/cPanel server today. As TerryE suggests, you are probably running CGI or suPHP. Change to DSO.
