Enabling Memcached on Cloud Platform¶

1. Download the Memcache API and Integration module, and then add the module to your codebase in the modules/contrib/memcache directory. We recommend to use Composer to install the module:

   composer require drupal/memcache
   

2. Add the composer package that contains the Acquia Memcache settings to your project:

   composer require acquia/memcache-settings
   

3. For each website that requires Memcached, edit the Cloud Platform database require line in settings.php with a PHP require_once statement, similar to the following example:

   if (file_exists('/var/www/site-php')) {
      require('/var/www/site-php/mysite/mysite-settings.inc');
   
      // Memcached settings for Acquia Hosting
      $memcache_settings_file = DRUPAL_ROOT . "/../vendor/acquia/memcache-settings/memcache.settings.php";
      if (file_exists($memcache_settings_file)) {
        require_once $memcache_settings_file;
      }
   }
   

   Note

   If you have the older cloud-memcache-d8+.php file stored in this repo, ensure that you delete it.

4. Rebuild caches by running the following command, replacing [example.com] with the domain name of your website:

   drush cr --uri=[example.com]
   

5. Truncate all cache_ tables in the database for the website.

Memcache is now enabled for your website. Continue to read the next section.
