    Hey! Did you try verifying your connection settings by connecting through the redis-cli?

    Thread Starter swiftc

    Sorry for delay, Yes I have other things like PHP Sessions being cached in another db also using AUTH OK via php.ini:

    ===
    session.save_handler = redis
    session.save_path = “tcp://127.0.0.1:6379?database=10&auth=mypass”
    ===

    That all works OK. But for WordPress via plugin I see this in Apache error_log:

    ===
    [01-Mar-2016 21:13:51 UTC] PHP Fatal error: Uncaught exception ‘RedisException’ with message ‘Failed to AUTH connection’ in /home/example/public_html/wp-content/plugins/wp-redis/object-cache.php:939

    Thanks for any help!

    Hey!

    I can’t reproduce your issue when using a password and the PECL Redis extension.

    However there might be a bug in PHPRedis: https://github.com/phpredis/phpredis/issues/661

    I’d recommend you ask your web developer to debug the WP_Object_Cache::__construct() in /wp-content/object-cache.php and if you find a bug, you can submit a PR to the GitHub repository: https://github.com/tillkruss/Redis-Object-Cache

    I hope this will help someone else.

    I resolved this by moving the below lines from “wp-config.php” to “object-cache.php”

    ===
    define(‘WP_REDIS_HOST’, ‘127.0.0.1’);
    define(‘WP_REDIS_PORT’, ‘6379’);
    define(‘WP_REDIS_DATABASE’, ‘1’);
    define(‘WP_REDIS_PASSWORD’, ‘mypass’);
    define(‘WP_CACHE_KEY_SALT’, ‘example.com’);
    ===

    Thanks.

    Did you try adding the Redis constants above the following line in your wp-config.php?

    require_once ABSPATH . 'wp-settings.php';
