🇬🇧 Enable caching for Trellis

FastCGI caching

FastCGI caching, which is said to be a better choice than Varnish, is build in into Trellis’ configuration. Read more on the Trellis documentation website below 👇. FastCGI Caching | Trellis Documentation | Roots

Configuration

• Check which group_vars section you wish to edit, ‘production’ or ‘staging’.
• Open the group_vars/production/wordpress_sites.yml file (for production)
• Add the following block

...
  cache:
    enabled: true
    duration: 30s
    skip_cache_uri: /wp-admin/|/xmlrpc.php|wp-.*.php|/feed/|index.php|sitemap(_index)?.xml
    skip_cache_cookie: comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in

Note: the ‘skip_cache_uri’ is important here. It excludes permalinks from being cached. This is the starting point when you have issues with caching.

Provision the server

• From the trellis/ folder run:

ansible-playbook server.yml -e env=production --tags=wordpress

This provisions the server with the newly created cache settings.
