php - Redis PHP 缓存 "ERR Not permitted"

Question

我正在尝试获取 Redis front-end cache to Wordpress去工作。我收到这个 fatal error :

    2013-06-07 01:46:12: (mod_fastcgi.c.2701) FastCGI-stderr: PHP Fatal error:  Uncaught exception 'Predis\ServerException' with message 'ERR operation not permitted' in /home/www/predis/lib/Predis/Client.php:291
    Stack trace:
    #0 /home/www/predis/lib/Predis/Client.php(233): Predis\Client->onResponseError(Object(Predis\Command\HashExists), Object(Predis\ResponseError))
    #1 /home/www/index-with-redis.php(76): Predis\Client->__call('hexists', Array)
    #2 /home/www/index-with-redis.php(76): Predis\Client->hexists('7de22495a3e5275...', '3e3299d491f3bac...')
    #3 {main}
      thrown in /home/www/predis/lib/Predis/Client.php on line 291

我有一个正常运行的 Redis 服务器(用它运行其他项目)。出于某种原因，我收到了 ERR Not permitted。有任何想法吗？

正如您在评论中所说，问题是未设置密码。对于将来看到此错误的任何人，您都希望通过以下方式实例化您的客户端:

my_client = new Predis\Client(array(
            "host" => "some_host",
            "port" => "some_port",
            "password" => "some_pw",
            "database" => "some_db_number"
        )
