[Xon]

Xon updated Redis Cache By Xon with a new update entry:

2.6.2 - Maintenance update

• Work-around for buggy browsers failing to request css URLs properly

[Mr. Jinx]

This add-on isn't anything special for pageCache support

I have a question about this.
So for pageCache we can use 'Redis' as provider instead of SV\RedisCache\Redis
Same goes for Sessions?
Or it doesn't matter...?

 

[Xon]

You can mix and match cache providers. Most of the simple caching this add-on (and other add-ons I've written) depend on the main caching provider being SV\RedisCache\Redis

@Xon What would be the optimal configuration for version 2.1 since I come from version 1.5 and this is my old conf. Thanks for response.

$config['cache']['enabled'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions']['cache_id_prefix'] = 'xffx_';
$config['cache']['backend'] = 'Redis';
$config['cache']['backendOptions'] = array(
       'server' => '127.0.0.1',
       'port' => 6379,
       'database' => 1,
       'connect_retries' => 2,
       'use_lua' => true,
       'compress_data' => 2,
       'read_timeout' => 1,
       'timeout' => 1,
   );
require(XenForo_Application::getInstance()->getConfigDir().'/SV/RedisCache/Installer.php');

 

[Xon]

It takes the same options as in XF2 for the config section (ie backendOptions) it requires a bit of tinkering but you should be able to just copy & past the contents of backendOptions like so;

//$config['cache']['sessions'] = true;
$config['cache']['enabled'] = true;
$config['cache']['namespace'] = 'xffx_';
$config['cache']['provider'] = 'SV\RedisCache\Redis';
$config['cache']['config']  = array(
       'server' => '127.0.0.1',
       'port' => 6379,
       'database' => 1,
       'connect_retries' => 2,
       'use_lua' => true,
       'compress_data' => 2,
       'read_timeout' => 1,
       'timeout' => 1,
    );

(don't need the installer line bit any more)

Optimal configuration can be a bit tricky to determine, keeping the same is easy (note; default for use_lua is true now)

How can we flush the redis cache from admin panel? @Xon

 

[Xon]

That isn't possible, and it generally shouldn't be required.

You can do this via the cli with; redis-cli flushall

 

[maxicep]

Thank you for inform.

I have one more question.
What about guest page caching feature of xenforo 2 naturally with this add-on? Are they different so is it configurable?
And should i remove the $config['cache']['sessions'] = true; parameter from config ?

@Xon

 

[Mik_27]

Forgive me the newbie silly question. I am trying to figure out why I should use Redis Cache By Xon opposite to install Redis myself on my VPS. I can't quite figure out what are the advantages. And I couldn't find an explanation or a post that spell this out.

Guest caching works, but support for it is beyond the scope of this add-on. It is reasonably straight forward to implement as there isn't much to configure.

And should i remove the $config['cache']['sessions'] = true; parameter from config ?

That will cause sessions to be stored in the database, resulting in extra db hits to load & save any session info.

This add-on is the connector between XenForo and Redis; you still need to install redis.

 

[maxicep]

What is right of the cache provider value?

'SV\RedisCache\Redis' or just 'Redis? or are they different ?

Because xenforo cache settings says that configure it as 'Redis' but your add-on says that 'SV\RedisCache\Redis' @Xon

Btw, i'm using css cache, guest page cache and your configuration both.

Thank you for your informations

 

[Xon]

SV\RedisCache\Redis is the provider my add-on adds, it support working without the phpredis extension, and other features which my other redis add-ons use.

Redis is just the XF provided redis adapter.

 

[Mik_27]

This add-on is the connector between XenForo and Redis; you still need to install redis.

As far as I understand XF has already its connector for Redis, as per its manual. Is there some additional control with this add-on?

This add-on has an overview page, and a bunch of other add-ons which depend on this add-on.

If you don't need any of the features and don't use any of the add-ons that depend on it; then the stock Redis connector would be sufficient.

 

[RobParker]

Just to clarify, what should I ask me hosts to instal?

This add-on uses Credis with a custom cache provider for Redis (based off Cm_Cache_Backend_Redis). For best performance, install the php extension: phpredis

You must have a Redis instance installed, this is likely not possible with shared hosting

This is a bit ambiguous. Do I JUST need phpredis installed or is phpredis some sort of extension to Redis and I also need Redis itself installed?

 

[Xon]

You must have redis server installed to use redis caching.

This add-on does not require phpredis extension installed and will operate without it; while the standard XenForo redis connector requires the phpredis extension.

@Xon

May i use your redis connector (SV\RedisCache\Redis) instead of standart 'Redis' for css and guest page cache features of Xenforo ?

 

[Xon]

Yes, this redis connector(SV\RedisCache\Redis) can be used where ever XF accepts a caching configuration (ie css & guest page caching).

 

[Nirjonadda]

Yes, this redis connector(SV\RedisCache\Redis) can be used where ever XF accepts a caching configuration (ie css & guest page caching).

@Xon Does this correct code for guest page cache features of Xenforo ? Also please let me know that what code need add for caching CSS?

// START Redis configuration //
$config['cache']['enabled'] = true;
$config['cache']['sessions'] = true;
$config['cache']['namespace'] = 'xfredis_';

$config['cache']['provider'] = 'SV\RedisCache\Redis';
$config['cache']['config'] = array(
'server' => '127.0.0.1',
'port' => 6379,
'connect_retries' => 2,
'use_lua' => true,
'compress_data' => 6,
'read_timeout' => 1,
'timeout' => 1,
'serializer' => 'igbinary',
//        'serializer' => 'php',
'persistent' => true,
);
// END Redis configuration //

// START Guest page caching //
$config['cache']['enabled'] = true;
$config['pageCache']['enabled'] = true;
$config['cache']['context']['page']['provider'] = 'SV\RedisCache\Redis';
$config['cache']['context']['page']['config'] = [];
// END Guest page caching //

 

[Xon]

You need to have the $config['cache']['context']['page']['config'] set; or it'll just use defaults and does not fall back on the global config.

$config['cache']['context']['css'] = [
            'namespace' => 'sv',
            'provider' => 'SV\RedisCache\Redis',
            'config' => [
'server' => '127.0.0.1',
'port' => 6380,
            ],
        ];

This will store CSS to a seperate redis instance on port 6380. There is only any point to adding the $config['cache']['context'] if they talk to a different backend
