How to Activate Memcached on Drupal<\/h2>\n\n\n\n

Preparations for Memcached<\/h3>\n\n\n\n

Before installing the Memcached module, please follow these instructions:<\/p>\n\n\n\n

    \n
  1. Activate Memcached, as explained in How to use Memcached<\/a>. <\/li>\n\n\n\n
  2. Take note of the Path<\/strong> to Linux sock to establish the link between Memcached and your web application (path \/home\/N0C_USERNAME\/.memcached\/memcached.sock), where N0C_USERNAME must be replaced by your real username:<\/li>\n<\/ol>\n\n\n
    \n
    \"Path<\/a><\/figure><\/div>\n\n\n
      \n
    1. Confirm that the Memcached<\/strong> server has been started (the Play<\/strong> button is automatically grayed out):<\/li>\n<\/ol>\n\n\n
      \n
      \"Confirm<\/a><\/figure><\/div>\n\n\n
        \n
      1. Go to Languages<\/strong> -> PHP<\/strong>, and activate the MEMCACHE and MEMCACHED extensions, as explained in How to use the PHP interface<\/a>: <\/li>\n<\/ol>\n\n\n
        \n
        \"activate<\/a><\/figure><\/div>\n\n\n
          \n
        1. Please refer to the article How to Use the MG Panel Terminal<\/a> to connect to the N0C hosting Terminal:<\/li>\n<\/ol>\n\n\n
          \n
          \"Connect<\/a><\/figure><\/div>\n\n\n
            \n
          1. Change the directory for the Drupal installation folder (here, public_html) by typing:<\/li>\n<\/ol>\n\n\n\n
            cd public_html<\/code><\/pre>\n\n\n\n
            Installing the Memcached Module<\/h3>\n\n\n\n
            You now need to install the Memcached module itself.<\/p>\n\n\n\n
              \n
            1. Still using the N0C hosting  Terminal and from the public_html working folder, run this command:<\/li>\n<\/ol>\n\n\n\n
              composer require drupal\/memcache<\/code><\/pre>\n\n\n\n
                \n
              1. You will get an installation confirmation:<\/li>\n<\/ol>\n\n\n
                \n
                \"Installing<\/a><\/figure><\/div>\n\n\n
                Activating the Memcached Module<\/h3>\n\n\n\n
                Once you have installed the Memcached module, you need to activate it.<\/p>\n\n\n\n
                  \n
                1. Log on to Drupal administration at https:\/\/yoursite\/admin, where yoursite<\/strong> is the name of your website.<\/li>\n\n\n\n
                2. Once in the admin interface, go to Manage<\/strong> -> Extend<\/strong> and check Memcache<\/strong>:<\/li>\n<\/ol>\n\n\n
                  \n
                  \"Activating<\/a><\/figure><\/div>\n\n\n
                    \n
                  1. At the bottom of the page, click on the Install<\/strong> button.<\/li>\n\n\n\n
                  2. If the installation is successful, Drupal will return a notification of success.<\/li>\n<\/ol>\n\n\n\n
                    Configuring Memcache in Drupal<\/h3>\n\n\n\n
                    Once the Memcache module has been activated, you need to configure it in Drupal.<\/p>\n\n\n\n
                      \n
                    1. Using N0C’s  Terminal or file editor, open the file sites\/default\/settings.php and put the following code at the end of the file (the code contains the socket path, which must be replaced by the path to the Linux socket noted in the Preparations for Memcached<\/a>):<\/li>\n<\/ol>\n\n\n\n
                      $settings['cache']['default'] = 'cache.backend.memcache';\/\/ Use UNIX socket instead of IP address and port\n$settings['memcache']['servers'] = ['unix:\/\/\/home\/N0C_USERNAME\/.memcached\/memcached.sock'=> '0']; \/\/ Replace with your socket path and use port '0'\/\/ Configure cache bins\n$settings['memcache']['bins'] = ['default' => 'default','cache' => 'cache','config' => 'config','data' => 'data',];\/\/ Key prefix to avoid conflicts\n$settings['memcache']['key_prefix'] = 'drupal_';<\/code><\/pre>\n\n\n\n
                        \n
                      1. In the  Terminal of the Web Project, check that the cache is working properly by doing a clear cache :<\/li>\n<\/ol>\n\n\n\n
                        [quuwmcjj@hc-probear-staging public_html]$  .\/vendor\/bin\/drush cache:clear\n\n Choose a cache to clear [render]:\n  [0] drush\n  [1] theme-registry\n  [2] router\n  [3] css-js\n  [4] render\n  [5] plugin\n  [6] bin\n  [7] container\n  [8] views\n > 0\n\n [success] 'drush' cache was cleared.\n[quuwmcjj@hc-probear-staging public_html]$ <\/code><\/pre>\n\n\n\n
                        This completes the activation of Memcached for Drupal.<\/p>\n\n\n\n
