Following steps are allowed to install memcache in drupal 7

1.Install the memcached binaries on your server. See How to install Memcache on Debian Etch[http://www.lullabot.com/articles/how_install_memcache_debian_etch ] or How to install Memcache on OSX [http://www.lullabot.com/articles/setup-memcached-mamp-sandbox-environmen... ]


2.Install the PECL memcache extension for PHP.

3. In settings.php add ini_set('memcache.hash_strategy','consistent');4. Put your site into offline mode.5. Download and install the memcache module [ http://drupal.org/project/memcache ]6. If you have previously been running the memcache module, run update.php.7. Apply the DRUPAL-5-cache-serialize.patch that comes with memcache module [memcache/patches]I applied DRUPAL-5-3-cache-serialize.patch hence I am using drupal 5.38. Start at least one instance of memcache on the server.[ex ./memcached -d -m 2048 -l 10.0.0.40 -p 11211 ]Here 11211 is an instance of memcache, 10.0.0.40 is the IP of the server, 2048 is the allocated memory.9. Add following in the settings.php$conf = array('cache_inc' => './sites/all/modules/memcache/memcache.inc','memcache_servers' => array('localhost:11211' => 'default',),'memcache_bins' =>array('cache' => 'default','cache_views' => 'default','cache_page' => 'default','cache_path' => 'default','cache_filter' => 'default','cache_menu' => 'default',),);10.Change memcache_stampede_semaphore time from 15 seconds to 600 in dmemcache.inc lineno:86if ($result->expire && $result->expire <= time() && $mc->add($full_key .'_semaphore', '', FALSE, variable_get('memcache_stampede_semaphore', 600))) {located in modules/memcache to get clear result of memcache.Every 600 seconds cache from memcache will be cleared. If this is not set we will not see any performance benefit. Refer links… http://drupal.org/files/issues/stampede.patch. http://drupal.org/node/295738.11. First time after install, truncate all cache tables that are memcached.12. Bring your site back online.13. To check the memcache status login as admin and check memcahce logs at /admin/logs/memcache.

Dependency Injection in Drupal 8

Here are the important nuggets: DI is a design pattern used in programming. DI uses composition. DI achieves inversion of control. Dependency == service that your class needs == object of a certain type. Inject == provide == compose == assemble. Container == service container == dependency container. Instead of using  \Drupal::service('foo_service') , get the service from the  $container  if using a class. And the important reasons: Externalizing dependencies makes code easier to test. It allows dependencies to be replaced without interfering with other functionality. Retrieving dependencies from the container is better for performance. Services: node.grant_storage The easiest examples to find are services that have arguments, because you can search *.services.yml files for the word "arguments". In  node.services.yml  for example, there is this entry: node.grant_storage: class: Drupal\node\NodeGrantDatabaseStorage argument...
