When you create a site with --wpredis
you get full page caching + object cache.
You must configure Redis plugin accordingly, and enable Redis object cache. I use the following code (run as root) to achieve this easily:
rm wp-content/cache/* -rfv
rm wp-content/advanced-cache.php
rm wp-content/object-cache.php
wp core update
wp core update-db
wp plugin activate nginx-helper
wp plugin activate redis-cache
wp plugin update --all
wp option update rt_wp_nginx_helper_options '{"log_level":"INFO","log_filesize":5,"enable_purge":1,"enable_map":0,"enable_log":0,"enable_stamp":0,"purge_homepage_on_new":1,"purge_homepage_on_edit":1,"purge_homepage_on_del":1,"purge_archive_on_new":1,"purge_archive_on_edit":1,"purge_archive_on_del":1,"purge_archive_on_new_comment":1,"purge_archive_on_deleted_comment":0,"purge_page_on_mod":1,"purge_page_on_new_comment":1,"purge_page_on_deleted_comment":1,"cache_method":"enable_redis","purge_method":"get_request","redis_hostname":"127.0.0.1","redis_port":"6379","redis_prefix":"nginx-cache:"}' --format=json
wp redis enable
This is a snippet from a script, so be aware this is not intended to be an universal solution for all cases.
But I think you don’t need the disclaimers.
