XF 1.2 How to properly enable memcached and apc?

[rdn]

This is my config right now:

<?php

// Cache
$config['cache']['enabled'] = true;
$config['cache']['cacheSessions'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions'] = array('caching'  =>  true,
                                            'automatic_serialization' => true,
                                            'lifetime'    => 3600,
                                            'cache_id_prefix'  =>  'phcn_'
);
// MemCache
$config['cache']['backend'] = 'Memcached';
$config['cache']['backendOptions'] = array(
    'compression' => false,
    'servers' => array(
        array(
           
            'host' => '127.0.0.1',
            'port' => 11211,
        )
    )
);
// End of Memcache
$config['cache']['backend'] = 'Apc';

But I cannot see it working on my memcache admin:

 

[rdn]

But APC works fine with me:

 

[MattW]

You don't need to use APC for the backend if you are using Memcache.

Your APC setting is overwriting Memcache, and using APC for the backend cache.

If you want to use Memcache for the backend, and APC as the OPcache, remove the ACP setting, as it will automatically cache the compiled PHP pages, and the backend will be put into Memcache.

 

[digitalpoint]

Well the last line of your config sets the config back to Apc.

 

[rdn]

remove the ACP setting, as it will automatically cache the compiled PHP pages, and the backend will be put into Memcache.

I'm confuse how to do this?
You mean APC line?

 

[MattW]

Yes, remove the APC line from your config.

 

[rdn]

Thanks @digitalpoint and @MattW
I change my config to this:

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


// Memcache
$config['cache']['backend'] = 'Memcached';
$config['cache']['backendOptions'] = array(
    'compression' => false,
    'servers' => array(
        array(
            'host' => '127.0.0.1',
            'port' => 11211,
        )
    )
);
// End Memcache

But facing a lot of error now
I don't know where to fix.
Already restart the server, doesn't fix.

I'm contacting xfrocks about the BD Widget error.
But the error I'm facing on admin "illegal srtring offset" I don't know what's causing this.

 

[MattW]

What does the memcache section of phpinfo say?

 

[rdn]

Here:

Just letting you know, you don't need APC if you're running 5.5.x.

 

[MattW]

You are running Libmemcached.

Change your config to this:

$config['cache']['backend']='Libmemcached';

 

[rdn]

Yes, I'm using php 5.5.7.
But I don't enable zend opcache, is it worth it to enable it?

 

[MattW]

Yes, I'm using php 5.5.7.
But I don't enable zend opcache, is it worth it to enable it?

Yes, I swapped out to Zend Opcache when I moved to 5.5.X

 

[rdn]

Thanks @MattW didn't know it's different.

 

[rdn]

Yes, I swapped out to Zend Opcache when I moved to 5.5.X

Then what line of code should be added into config.php to enable Zend Opcache?

 

[MattW]

Then what line of code should be added into config.php to enable Zend Opcache?

You don't need to. It will cache the PHP pages by default (same as APC if you don't use it for the backend).

This is what I have:

$config['cache']['enabled'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions']['cache_id_prefix'] = 'xf_';
$config['cache']['frontendOptions']['automatic_serialization'] = true;
$config['cache']['cacheSessions'] = true;
$config['cache']['backend']='Libmemcached';
$config['cache']['backendOptions']=array(
      'compression'=>false,
      'servers' => array(
              array(
                      'host'=>'127.0.0.1',
                      'port'=>'11211',
                      'persistent' => 'true'
                )
      )
);

and just enable zendopcache in the .ini file that centminmod creates

[root@astra library]# cd /root/centminmod/php.d/
[root@astra php.d]# vim zendopcache.ini

zend_extension=opcache.so
opcache.error_log=/var/log/php_opcache_error.log
opcache.enable=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_wasted_percentage=5
opcache.max_accelerated_files=8000
opcache.validate_timestamps=1
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=0
opcache.save_comments=1
opcache.enable_file_override=1
opcache.validate_timestamps=1

 

[rdn]

When I enable: $config['cache']['frontendOptions']['automatic_serialization'] = true;
I got an error:

 

[MattW]

Just remove that line then, you might not need it. It was in mine from when I had Xcache installed.

 

[rdn]

When I enable: $config['cache']['frontendOptions']['automatic_serialization'] = true;
I got an error:

Already fixed this by restarting memcache.
