Defining a Cache help

[nodle]

I have been searching and reading all evening on enabling a front end cache and a back end cache. According to this:

http://xenforo.com/help/cache/

I just need to add the lines of code which I have. But one little part confuses me. Should I also add this line?

$config['cache']['cacheSessions'] = true;

I added these:

$config['cache']['enabled'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions']['cache_id_prefix'] = 'xf_';
$config['cache']['cacheSessions'] = true;

Now according to this thread @Jake Bunce said it should be written to "cache_dir" under your tmp directory. But After enabling it this afternoon I am still not seeing any data or folder being created or written to. Is this because I didn't add the line of code listed above? Any help would be appreciated. I just want to make sure its working.

Please read: http://xenforo.com/community/threads/file-cache-coding.57905/

So we have to define the cache directory? I thought it would just default to tmp?

Yes, create it manually then chmod 777.

Ok and do I need to add the code that I left out above also? This one:

$config['cache']['cacheSessions'] = true;

Yes if you'd like.
It's better

This is what I'm using before:

// File Cache
$config['cache']['backend'] = 'File';
$config['cache']['backendOptions'] = array('cache_dir'  => '/home/public_html/internal_data/cache');
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions'] = array('caching'  =>  true,
                                            'automatic_serialization' => true,
                                            'lifetime'    => 1800
);
//End File Cache

 

[nodle]

What do these options do?

'automatic_serialization' => true,
                                            'lifetime'    => 1800

Also if I create a folder to dump everything into. Does it manually remove the items that are no longer needed to use after a time?

 

[nodle]

I tried adding this but it just takes my site offline:

// File Cache
$config['cache']['enabled'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions']['cache_id_prefix'] = 'xf_';
$config['cache']['cacheSessions'] = true;
$config['cache']['backend'] = 'File';
$config['cache']['backendOptions'] ['cache_dir'] = '/home/tmp/xentmp';
//End File Cache

I created the xentmp folder with 777 permissions also.

 

[rdn]

Change this line; /home/tmp/xentmp to your forumroot/internal_dala/cache

 

[nodle]

Ok I created that folder in there as "cache" with 777 permissions. Then added this:

// File Cache
$config['cache']['enabled'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions']['cache_id_prefix'] = 'xf_';
$config['cache']['cacheSessions'] = true;
$config['cache']['backend'] = 'File';
$config['cache']['backendOptions'] ['cache_dir'] = '/home/public_html/internal_data/cache';
//End File Cache

But then I just get "An unexpected error occurred. Please try again later." Do I have to have APC installed first or something or should it just work?

Replace all your caching code on config.php with this:

// Cache
$config['cache']['enabled'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['cacheSessions'] = true;

// File Cache
$config['cache']['backend'] = 'File';
$config['cache']['backendOptions'] = array('cache_dir'  => '/home/fluxoid/public_html/internal_data/cache');
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions'] = array('caching'  =>  true,
                                            'automatic_serialization' => true,
                                            'lifetime'    => 1800,
                                            'cache_id_prefix'  =>  'fx_'
);
// End File Cache

Assuming this is the correct/full path: /home/fluxoid/public_html/internal_data/cache

 

[nodle]

Ok I will try this. What are these options for?

'automatic_serialization' => true,'lifetime' => 1800,

 

[rdn]

Ok I will try this. What are these options for?

I could't explain it more deeper sorry
I guess it's built-in with Zend/XenForo

 

[nodle]

Ok @RoldanLT I must had forgot my web name in my path. That fixed it. I appreciate all your help!

Yes, create it manually then chmod 777.

You should NEVER chmod a directory to 0777. XenForo has options to define proper permissions:
$config['chmodWritableValue'] = 0644;

$config['chmodWritableValue'] = 0644;

For files, How about for folders?

 

[Floren]

It does it for both, try it.

 

[rdn]

find /home/nginx/domains/phcorner.net/public/ -type d -exec chmod -R 755 {} \;
find /home/nginx/domains/phcorner.net/public/ -type f -exec chmod -R 644 {} \;

Yeah!
All uploads still working after setting this.
But still I'm not using this: $config['chmodWritableValue'] = 0644;

 

[Floren]

The 'chmodWritableValue' forces the new added files to have proper permissions.
In your case, this will not happen, you will get an error. This is what I do on my server:
I own the directory with an PHP-FPM defined user, (in my case php-fpm, but could be apache, nginx etc., whatever you define in your php-fpm.conf). Then I insert 'chmodWritableValue' into config.php so all new directories and files will be either 0755 or 0644 and owned by PHP-FPM user.
