Nginx Lot of 502 errors after upgrading to PHP 5.6.4

Thank you very much, it worked.

Now upgrading to PHP 5.6.4, it asked me:

---

Code:

Do you want to update to latest php-fpm.conf ? It will overwrite your existing php-fpm.conf [y/n]:
Do you want to use Zend OPcache [y/n] ?

To first one I said yes, what should I say to Zend? It says it is an alternative to APC cache and xchache.
What should I do?
I want to run a Xenforo forum, what to do here?

 

It's up to you what cache you want to use

If you want APC cache just say no as APC will cache also data.
Zend opcache is a bit faster but it doesn't cache data and you should enable and use another cache for data as Memcached .

 

What the hell do I know which cache I want to use ? I have no clue about the pros and cons. I said no.

 

Ok check the APC and later you can try Zendopcache + Memcached so you can compare them

 

Ok, I searched the forum now and see that most of the guys use Zend + Memcache instead of APC alone. Is this correct?
And how can I disable APC and activate Zend and Memcache?

 

You can select it from centminmod menu and it will auto disable apc ...

Memcached should be installed as default.
