Configuring Automatic Background Updates – WordPress

Update Types

Automatic background updates were introduced in WordPress 3.7 in an effort to promote better security, and to streamline the update experience overall. By default, only minor releases – such as for maintenance and security purposes – and translation file updates are enabled on most sites. In special cases, plugins and themes may be updated.

Setting up Automatic Update for All WordPress Plugins

You can set WordPress to automatically install all plugin updates by simply adding this code to your theme’s functions.php file or a site-specific plugin.

add_filter( 'auto_update_plugin', '__return_true' );

This filter tells WordPress automatic updater to automatically install plugin updates when they’re available.
If you also want to automatically update your themes, then you can add another code like this:

WordPress auto update config

1. disable FTP commands from config.php
2. add to config.php

// Update core
define( 'WP_AUTO_UPDATE_CORE', true );

optionally for Synology NAS

# reset chown for Synology user nobody
chown -R nobody:nobody /web/wordpress/dir

find . -type f -exec chmod 0644 {} \;
find . -type d -exec chmod 0755 {} \;
