希望在CI中使用redis作为缓存驱动，发现官方github上已经有了，貌似要到3.0才正式发布，先用上吧，省事了
为了保持框架可升级操作如下
1、将systemlibrariesCacheCache.php复制为applicationlibrariesCacheCache.php
增加配置
protected $valid_drivers
= array(
'cache_apc', 'cache_file', 'cache_memcached', 'cache_dummy', 'cache_redis'
);
2、将https://github.com/EllisLab/CodeIgniter/blob/develop/system/libraries /Cache/drivers/Cache_redis.php放到applicationlibrariesCachedrivers下
3、测试
$this->load->driver('cache', array('adapter' => 'redis'));
if ( ! $foo = $this->cache->get('foo'))
{
echo 'Saving to the cache!
';
$foo = 'foobarbaz!';
// Save into the cache for 5 minutes
$this->cache->save('foo', $foo, 300);
}
echo $foo;
'cache_apc', 'cache_file', 'cache_memcached', 'cache_dummy', 'cache_redis'
);
