如何使 Laravel 在 AWS 上使用 Redis 集群

How to make Laravel work with Redis cluster on AWS

我正在尝试将 Laravel (5.4) 与集群版本的 Redis 一起使用。我按照 的说明进行操作,如下所示:

/*
|--------------------------------------------------------------------------
| Redis Databases
|--------------------------------------------------------------------------
|
| Redis is an open source, fast, and advanced key-value store that also
| provides a richer set of commands than a typical key-value systems
| such as APC or Memcached. Laravel makes it easy to dig right in.
|
 */

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

     'default' => [
            'host' => env('REDIS_HOST_1', '127.0.0.1'),
            'password' => env('REDIS_PASSWORD', null),
            'port' => 6379,
            'database' => 0,
     ],


    'clusters' => [
         'default' => [
            'host' => env('REDIS_HOST_1', '127.0.01'),
            'password' => env('REDIS_PASSWORD', null),
            'port' => 6379,
            'database' => 0,
        ],
        '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'
    ],
]

但我一直收到此错误

请注意,我没有对应用程序数据进行任何更改,因此我的 Redis 代码仍然如下所示:

use Illuminate\Support\Facades\Redis;
..

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

此外,如果我从上面的配置中删除默认值,它看起来像这样:

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

    'clusters' => [
         'default' => [
            'host' => env('REDIS_HOST_1', '127.0.01'),
            'password' => env('REDIS_PASSWORD', null),
            'port' => 6379,
            'database' => 0,
        ],
        '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'
    ],
]

我收到这个错误

所以从错误消息来看,Predis 似乎只是忽略了我的集群配置并直接从默认读取,而默认不知道如何处理我的集群 Redis 数据存储。想法?

经过搜索和调试,这就是它的工作原理:

'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:我在上述问题中的配置中的一个明显错误是我将主机和端口组合在一起,我已在此处修复。这是我的 .env 文件的样子:

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:我使用此处的说明创建了集群:https://redis.io/topics/cluster-tutorial#creating-the-cluster

研究方法

由于: 1. laravel/predis 文档缺失 2. 大多数关于堆栈溢出的答案都是这样的:在谷歌搜索和搜索之后..这对我来说是有效的 没有太多解释发生了什么

我想我可以通过展示如何我找到上述问题的答案来提供一些帮助。

1) 解决报错问题

解决这个错误

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 格式完全错误。谷歌搜索并没有给我任何清晰的图片,所以我决定在代码中使用 xdebug and dive 。注意:我在一个文档中打印了错误堆栈跟踪(在上面的问题中显示),我将其用作鸟瞰图来指导我完成调试步骤(即步进 over/into/out 等,同时始终打印输出在一个单独的文档中并将其与我的 config/database.php 作为理智 check/debug 指南针进行比较。

在挖掘和打印后,我发现了这个:

[ *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)
  /

我将其与我的 .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

我意识到格式错误,我不应该将主机和端口放在同一个环境变量中..所以我这样写:

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

这解决了我的第一个问题。

2) 解决其他问题

在上述问题得到解决后,我得到了这个

CLUSTERDOWN Hash slot not served

这非常简单,只需谷歌搜索错误消息即可(因为错误消息显然是本机 Redis 错误消息,而不是像 predis 错误消息这样的神秘库包装器)。我发现this answer

剩下的就简单了。
