如何在AWS上让Laravel与Redis集群配合工作

Question

我正在尝试使用Laravel (5.4)与Redis的集群版本。我按照这篇文章中的说明进行了操作：

        ],
        'jobs' => [
            'host' => env('REDIS_HOST_2', '127.0.0.1'),
            'password' => env('REDIS_PASSWORD', null),
            'port'     => 6379,
            'database' => 0,
        ],
        'content' => [
            'host' => env('REDIS_HOST_3', '127.0.0.1'),
            'password' => env('REDIS_PASSWORD', null),
            'port'     => 6379,
            'database' => 0,
        ]
   ],

    'options' => [
        'cluster' => 'redis'
    ],
]

最初的回答是，但我一直收到这个错误。

但是，我一直遇到这个错误。

请注意，我没有进行任何应用程序数据更改，因此我的Redis代码仍然如下所示：

注意我没有进行任何应用程序数据更改，因此我的Redis代码仍然如下所示：

use Illuminate\Support\Facades\Redis;
..

Redis::set('key', 'val');

进一步地，如果我从上述配置中删除默认值，使其如下所示：

'redis' => [
     'client' => 'predis',
     'cluster' => 'true',

    'clusters' => [
         'default' => [
            'host' => env('REDIS_HOST_1', '127.0.01'),
            'password' => env('REDIS_PASSWORD', null),

        ]
   ],

    'options' => [
        'cluster' => 'redis'
    ],
]

所以从错误信息来看，似乎Predis简单地忽略了我的集群配置并直接从默认配置读取，而默认配置不知道如何处理我的集群化Redis数据存储。有什么想法吗？翻译成中文：根据错误信息显示，Predis好像无视了我的集群配置，而是直接从默认配置读取；但是默认配置并不知道如何处理我的集群化Redis数据存储。您有什么建议吗？ "Original Answer"翻译成中文为"最初的答案"。

Answer 1

经过搜索和调试，这就是让它工作的方法：

'redis' => [
    'client' => 'predis',
    'cluster' => true,
    'options' => [
        'cluster' => 'redis',
        'parameters' => [
            'host' => env('REDIS_DEFAULT_HOST', '127.0.01'),
            'password' => env('REDIS_PASSWORD', null),
            'port' => env('REDIS_DEFAULT_PORT', 6379),
            'database' => 0,
            ],
        ],
    'clusters' => [
         'default' => [
            'host' => env('REDIS_DEFAULT_HOST', '127.0.01'),
            'password' => env('REDIS_PASSWORD', null),
            'port' => env('REDIS_DEFAULT_PORT', 6379),
            'database' => 0,
        ],
        'jobs' => [
            'host' => env('REDIS_JOBS_HOST', '127.0.01'),
            'password' => env('REDIS_PASSWORD', null),
            'port' => env('REDIS_JOBS_PORT', 6379),
            'database' => 0,
        ],
        'content' => [
            'host' => env('REDIS_CONTENT_HOST', '127.0.01'),
            'password' => env('REDIS_PASSWORD', null),
            'port' => env('REDIS_CONTENT_PORT', 6379),
            'database' => 0,
        ],
        'options' => [
            'cluster' => 'redis'
        ],
    ]
]

注意：在我上面的问题中，我的配置存在一个明显的错误，即我将主机名和端口号组合在一起，我已经在这里进行了修复。以下是我的 .env 文件内容：

note: 上述问题中我的配置有一个明显的错误，我将主机名和端口号合并在了一起，已经进行了更正。下面是我的 .env 文件内容：

REDIS_DEFAULT_HOST=127.0.0.1
REDIS_JOBS_HOST=127.0.0.1
REDIS_CONTENT_HOST=127.0.0.1

REDIS_DEFAULT_PORT=7000
REDIS_JOBS_PORT=7001
REDIS_CONTENT_PORT=7002

注意：我是根据此处的说明创建集群：https://redis.io/topics/cluster-tutorial#creating-the-cluster

研究方法

由于以下原因： 1. laravel/predis文档不够详细 2. 大多数stackoverflow上的答案都是这样的：通过谷歌搜索和查找，这是让我成功的方法，没有解释发生了什么。

我想通过展示我如何找到答案来帮助大家一些。

1）解决错误问题

为了解决这个错误bug

local.ERROR: Symfony\Component\Debug\Exception\FatalThrowableError: Type error: Argument 1 passed to Predis\Connection\Parameters::__construct() must be of the type array, integer given, called in /Users/Shared/dev/php/toters-api/vendor/predis/predis/src/Connection/Factory.php on line 164 in /Users/Shared/dev/php/toters-api/vendor/predis/predis/src/Connection/Parameters.php:34 Stack trace:

我意识到我的config/database.php格式是有问题的。在各种谷歌搜索中都没有给我一个清晰的图片，所以我决定使用xdebug并dive进入代码。注意：我在一个文档中打印了错误堆栈跟踪（如上所示），并将其用作通过调试步骤的鸟瞰视图（即一直打印输出到另一个文档，并将其与我的config/database.php作为健全检查/调试指南进行比较）。

经过挖掘和打印，我找到了这个：

[ *Locals ] [ Superglobals ] [ User defined constants ]

- Locals at /Users/Shared/dev/php/toters-api/vendor/predis/predis/src/Client.php:55

 ▾ $options = (array [1])
  \
   ⬦ $options["cluster"] = (string [5]) `redis`
  /
 ▾ $parameters = (array [4])
  \
   ⬦ $parameters[0] = (string [14]) `127.0.0.1:7000`
   |
   ⬦ $parameters[1] = (null)
   |
   ⬦ $parameters[2] = (int) 6379
   |
   ⬦ $parameters[3] = (int) 0
  /
 ▾ $this = (Predis\Client [3])
  \
   ⬦ $this->connection = (null)
   |
   ⬦ $this->options = (null)
   |
   ⬦ $this->profile = (null)
  /

我将此与我的.env文件的内容进行了比较：

REDIS_DEFAULT_HOST=127.0.0.1:7000
REDIS_JOBS_HOST=127.0.0.1:7001
REDIS_CONTENT_HOST=127.0.0.1:7002

后来我意识到格式是错误的，我不应该把主机和端口放在同一个环境变量中...所以我改成了这样:

REDIS_DEFAULT_HOST=127.0.0.1
REDIS_JOBS_HOST=127.0.0.1
REDIS_CONTENT_HOST=127.0.0.1

REDIS_DEFAULT_PORT=7000
REDIS_JOBS_PORT=7001
REDIS_CONTENT_PORT=7002

并且这解决了我的第一个问题。

2) 解决其他问题

在解决了上述问题后，我遇到了以下错误：

CLUSTERDOWN 哈希槽未被服务

这很容易解决，只需要谷歌一下错误信息即可（因为该错误明显是Redis原生错误消息，而不是像Predis错误消息那样晦涩难懂的库包装器）。我找到了这个答案。

其余部分很容易。
