How to set up APC and Memcached caches for Vanilla?

I have installed memcached on my VPS and set these lines in config.php

// Cache
$Configuration['Cache']['Enabled'] = true;
$Configuration['Cache']['Method'] = 'memcached';

// memcached
$Configuration['memcached']['Store'] = 'localhost';

1# Question: Am i allowed to use APC cache together with Memcached and cloudflare (DNS)?
2# Question: Do i have to add something in config file to activate APC cache for vanilla?

    I have Memcached running with CloudFlare, and there have been no issues I know of.

    I was looking up about APC after seeing your post, but noticed that support for that seems to end with php5.4, and that the recommendation is to go with OPcache instead.

    I have no real knowledge as to whether this is correct (beyond reading on the InterWebby).

  • @whu606 you are right. I was few minutes ago advised also to go for Opcache because APC is no longer updated.

    Will activating Opcache affect both my wordpress and vanilla forums installation or i can make it just affect vanilla forum? (in a way that we have to enable it in confing or something)

    You can configure blacklists for opcache, so that creating a file and putting /var/www/wordpress_folder/* would exclude your wordpress.
    You have to add some settings to your php.ini: opcache.blacklist_filename=/etc/php5/opcache-blacklist.txt

    Also make sure that you have in some config file. In order to check if opcache is up and running, look at the output of phpinfo()

    Sorry, I only have Vanilla, so couldn't say.

    In nginx the change to enable it is made in php - fpm - php.ini file, so I guess it would depend if you had separate instances of this for Wordpress and Vanilla, but I'm only guessing.

    I'm sure someone else will know definitively.

    I enabled OPcache and it is running without having to set a Vanilla configuration.

    Seems to have speeded up my site, so thanks for the OP, which made me look it up.

  • Thank you a lot guys and @whu606 glad the topic helped you too! :)

    I will enable Opcache and will let you all know if something went wrong!
