Redis Not Connected with ACL

Would you mind posting the diagnostics from the plugin’s settings?

You’ll have to use PhpRedis as the client most likely.

The correct auth would be:

define('WP_REDIS_PASSWORD', ['user', 'password']);

Switched out the config for your syntax, disabled, ran flushall, enabled.

Current wp-config:

//Begin Redis config

define('WP_REDIS_PASSWORD', ['default', 'password']);
define('WP_REDIS_HOST', '127.0.0.1');
define('WP_REDIS_PORT', '6379');
define('WP_REDIS_CLIENT', 'pecl' );
define('WP_REDIS_SERIALIZER', 'Redis::SERIALIZER_PHP' );
define('WP_REDIS_DISABLE_BANNERS', 'true');

Diagnostics:

The plugin only recognizes:

WP_REDIS_PREFIX: "domain.com"
WP_CACHE_KEY_SALT: "domain.com"

You need to move the other configuration much higher in your wp-config.php.

This is the top of my wp-config:

<?php
//Begin Redis config
define('WP_REDIS_PASSWORD', ['default', 'password']);
define('WP_REDIS_HOST', '127.0.0.1');
define('WP_REDIS_PORT', '6379');
define('WP_REDIS_CLIENT', 'pecl' );
define('WP_REDIS_SERIALIZER', 'Redis::SERIALIZER_PHP' );
define('WP_REDIS_DISABLE_BANNERS', 'true');
// END Redis config	

define('WP_CACHE', true); // Added by WP Rocket
define('WP_CACHE_KEY_SALT', 'domain.com');

/**
 * The base configuration for WordPress

Your diagnostics don’t reflect that, so it must be a configuration issue on your end.

I just tested ACL connections and it works for me on v2.0.3: https://imgur.com/a/MXn11DB

I decided to start looking over stuff from the start, pretending like I was installing from scratch. I tried turning auth off in the config file and now it connects perfectly.

Do you have anything specific set for that section in your own config file?

I’m using a default Redis config and ran this command:

acl setuser admin on >secret allcommands allkeys

Can you provide me admin access to your installation to have a closer look?

To clarify, the auth was for /etc/redis/redis.conf

I still have the acl user listed above which I was able to connect to.

I messaged you on WordPress dev slack channel if you want to coordinate login info
