wp cron job check working or not disable enable change schedule

 

Problem with default wp cron job?

every page load its running. high cpu and low performance issues.

The WordPress cron is run by the wp_cron() function, which is hooked to run on the init hook, which runs on every page load.

wp_cron() is defined in wp-includes/cron.php and hooked in wp-includes/default-filters.php.

The wp_cron() function kicks off a wp_remote_post() request to /wp-cron.php. Some server configurations prevent scripts sending a request to the same domain like this however, so as an alternative you can set the ALTERNATE_WP_CRON constant to true. When enabled this redirects the user to the current URL but with ?doing_wp_cron= added to the URL, instead of the post request.

What happens if WP-Cron stops working?

WordPress, Themes, and Plugins would never know if a new version is out.
Scheduled posts would never get published, auto drafts never deleted

As you may already know, WP-Cron jobs are not real cron jobs and are executed only when you have visits on your site.

add the following line to your wp-config.php: define('DISABLE_WP_CRON', true);

Then, manually a cron job every 15 minutes (it should be enough for most websites):

sudo crontab -e
0 * * * * su daemon -s /bin/sh -c "cd /opt/bitnami/apps/wordpress/htdocs/; /opt/bitnami/php/bin/php -q wp-cron.php"

 

*/15 * * * * wget -q -O - https://www.website.com/wp-cron.php?doing_wp_cron &>/dev/null

or

*/15 * * * * curl https://www.website.com/wp-cron.php?doing_wp_cron &>/dev/null

or

*/15 * * * * cd /home/user/public_html; php wp-cron.php &>/dev/null

Make sure you test that your tasks still run after this change!
