{% set cron = render_var(url('system.cron_settings')) %}

<h2>{% trans %}Goal{% endtrans %}</h2>

<p>{% trans %}Configure your system so that cron will run automatically.{% endtrans %}</p>

<h2>{% trans %}What are cron tasks?{% endtrans %}</h2>

<p>{% trans %}To ensure that your site and its modules continue to function well, a group of administrative operations should be run periodically. These operations are called <em>cron</em> tasks, and running the tasks is known as <em>running cron</em>. Depending on how often content is updated on your site, you might need to run cron on a schedule ranging from hourly to weekly to keep your site running well.{% endtrans %}</p>

<h2>{% trans %}What options are available for running cron?{% endtrans %}</h2>

<ul>

  <li>{% trans %}If the core Automated Cron module is installed, your site will run cron periodically, on a schedule you can configure.{% endtrans %}</li>

  <li>{% trans %}You can set up a task on your web server to visit the <em> cron URL</em>, which is unique to your site, on a schedule.{% endtrans %}</li>

  <li>{% trans %}You can also run cron manually, but this is not the recommended way to make sure it is run periodically.{% endtrans %}</li>

</ul>

<h2>{% trans %}Steps{% endtrans %}</h2>

<ol>

  <li>{% trans %}In the <em>Manage</em> administration menu, navigate to <em>Configuration</em> &gt; <em>System</em> &gt; <a href="{{ cron }}"><em>Cron</em></a>. Note the <em>Last run</em> time on the page.{% endtrans %}</li>

  <li>{% trans %}If you want to run cron right now, click <em>Run cron</em> and wait for cron to finish.{% endtrans %}</li>

  <li>{% trans %}If you have a way to configure tasks on your web server, copy the link where it says <em>To run cron from outside the site, go to</em>. Set up a task to visit that URL on your desired cron schedule, such as once an hour or once a week. (On Linux-like servers, you can use the <em>wget</em> command to visit a URL.) If you configure an outside task, you should uninstall the Automated Cron module.{% endtrans %}</li>

  <li>{% trans %}If you are not configuring an outside task, and you have the core Automated Cron module installed, select a schedule for automated cron runs in <em>Cron settings</em> &gt; <em>Run cron every</em>. Click <em>Save configuration</em>.{% endtrans %}</li>

</ol>

<h2>{% trans %}What is a module?{% endtrans %}</h2>

<p>{% trans %}A <em>module</em> is a set of PHP, JavaScript, and/or CSS files that extends site features and adds functionality. A set of <em>Core modules</em> is distributed as part of the core software download. Additional <em>Contributed modules</em> can be downloaded separately from the <a href="https://www.drupal.org/project/project_module">Download &amp; Extend page on drupal.org</a>.{% endtrans %}</p>

<h2>{% trans %}What is an Experimental module?{% endtrans %}</h2>

<p>{% trans %}An <em>Experimental</em> module is a module that is still in development and is not yet stable. Using Experimental modules on production sites is not recommended.{% endtrans %}</p>

<h2>{% trans %}What are installing and uninstalling?{% endtrans %}</h2>

<p>{% trans %}Installing a core or downloaded contributed module means turning it on, so that you can use its features and functionality. Uninstalling means turning it off and removing all of its configuration. A module cannot be uninstalled if another installed module depends on it, or if you have created content on your site using the module -- you would need to delete the content and uninstall dependent modules first.{% endtrans %}</p>
