W3 Total Cache and Opcode: Alternative PHP Cache (APC)

WordPress Nginx
#1

I installed Wordpress with Nginx thanks to your excellent EasyEngine without a problem, but I can’t activate Database Cache – Opcode: Alternative PHP Cache (APC) and Object Cache - Opcode: Alternative PHP Cache (APC) in W3 Total Cache plugin. These options are grayed out. I understand that I need to install additional components, but when I do… I usually screw up my whole site install. Please, advise what to do.

We are no longer using APC.

You can follow this and have memcache installed - http://rtcamp.com/tutorials/php/memcache/

After that you should be able to see “memcache” option highlighted for object and database cache.

For opcache, you can use PHP’s zend opcache - http://rtcamp.com/tutorials/php/zend-opcache/

Please note that you won’t see any option or setting for opcache in W3TC.

Thank you! Now it works as intended. One more question. You stated in the documentation that these are the best settings:

Page Cache – Disk Enhanced
Minify – Disabled (unless you are 100% sure your theme/plugin will support it nicely)
Database Cache – Opcode: Alternative PHP Cache (APC)
Object Cache - Opcode: Alternative PHP Cache (APC)
Browser Cache – Disabled

What are the optimal cache parameters for W3 total cache plugin using with easy engine nowadays?

#4
Database Cache – Opcode: Alternative PHP Cache (APC) Object Cache – Opcode: Alternative PHP Cache (APC)

For above two, we use Memcache backend. Rest all stays same.

I will update articles soon. Thanks for bringing it to my notice.
