Can connect only as default user

    Hello,

    I can connect from WordPress to Redis as default user, defined in redis.conf thusly:

    #define( ‘WP_REDIS_USER’, ‘<user>’ );
    #define( ‘WP_REDIS_PASSWORD’, ‘<password>’);
    define( ‘WP_REDIS_PASSWORD’, ‘paessword’);

    When I comment the third line and un-comment the first two I cannot connect to the same Redis database. This error message appears in diagnostics:

    Connection Exception: WRONGPASS invalid username-password pair or user is disabled. (RedisException)
    Errors: [
    “WRONGPASS invalid username-password pair or user is disabled.”
    ]

    However, I can connect with a PHP script that uses those same credentials:

    <?php

header('Content-type: text/plain');

$redis = new Redis();
//Connecting to Redis
$redis->connect('<servername>', 6379);
$redis->auth(['<user>', '<password>]);
 
if ($redis->ping()) {
        echo "PONG\n";
}
 
?>

    IIRC, I was able to connect to Redis as a user I had defined in redis.conf. I don’t know what the cause of this error is.

    How can I fix this?

    Hi!

    Can you post your diagnostics from the plugin settings screen?

    My guess is the WP_REDIS_HOST definition is too far down the config.

    I noticed that the diagnostics tab was displaying the Redis variables in a different order than wp-config.php, so I changed wp-config.php to match that order. REDIS_PASSWORD is the last of the Redis variables, with REDIS_USER preceding it, if it is used.

    It says “Status: Connected”, what’s the issue exactly?

    I want to connect from WordPress to Redis as a specific user. This user will have a specific ACL applied to it.

    I can connect only if I specify the default user. In redis.conf, it is this:

    requirepass ‘<password>’

    …and in wp-config.php, I declare REDIS_PASSWORD, but not REDIS_USER.

    Connection fails if I try to connect as user benfa, specified in redis.conf like this:

    user benfa allcommands allkeys on >'<password>’

    …and in wp-config.php, I declare both REDIS_USER and REDIS_PASSWORD.

    Ah, your answer is documented here: https://github.com/rhubarbgroup/redis-cache/wiki/Connection-Parameters#wp_redis_password-default-not-set
