How do I specify the Redis database number?

Hey @xintv123,

If $_SERVER['CACHE_HOST'] is set, you can specify a Redis database with $_SERVER['CACHE_DB'].

Here’s the logic around how the database details are retrieved: https://github.com/pantheon-systems/wp-redis/blob/7dae4488e68ac71a40d7208581651e1ad758ac1b/object-cache.php#L1156-L1172

Hope this helps! Let me know if we can clarify further.

Hello, I added define(‘CACHE_DB’, ‘1’); in wp-config.php but it doesn’t work, the cache still saves the database number 0, I am not a developer, can I help me?
