xcache config for dummies (like me)

Can anyone tell me the best way to setup the cache setting in config for xcache, I dont really understand it to well, is it best to configure the Cache Front-end and Back-end or just one of them

Any advise would be great

thanks

sorry I wasnt clear - its already installed on my sever, I just wasnt sure what was best to put in the xenforo config.php file

What about the front-end?

I have read that, but its not really clear if its best to have front and back configured or just back or just front - whats the best combo?

I use this cache config in XenForo configuration for XCache:

Code:

$config['cache'] = array(
    'enabled' => true,
    'frontend' => 'Core',
    'frontendOptions' => array(
            'caching' => true,
            'automatic_serialization' => false,
            'cache_id_prefix' => 'you_prefix_',
            'lifetime' => 18000
    ),
    'backend' => 'Xcache',
    'backendOptions' => array(),
    'cacheSessions' => true
);

When I set the cache to file I had thousands of files in my cache_dir.

Adding this:

Code:

$config['cache']['backendOptions']['hashed_directory_level'] = '1';

Put them all neatly into hash dirs decreasing seek and destroy times, something to consider if your site is active.

We are on a good sized VPS, however the host is telling us we cant use the caching feature because;

To install one, they need to disable Automatic Updates, mod_suphp will be changed with mod_php and these are not recommended due to high security risks.

Any suggestions?

Do they just manage the VPS for you? Do you have any other sites on the VPS?

I have a VPS, and to get Xcache working, I had to change from suPHP to FCGI for the PHP handler, as APC/Xcache doesn't work with suPHP.

Its managed, and it is the only site on the VPS.

If it is the only site on the VPS, there is no need to be running suPHP, you can run in DSO (mod_php), and Xcache will work fine (as there is no one else on the site which could be exploited if your own site was hacked).

Are you running a control panel on the VPS (Cpanel or Plesk)?

Neither, its a custom CP, I wonder if I can just run this, if it would help any.

File cache will work with suPHP

Thanks mate. Any problems with switching to file cache on busy site?
