php-如何使Laravel在AWS上与Redis集群一起使用

2022-09-05 18:13:38

我正在尝试将Laravel(5.4)与Redis的群集版本一起使用.我按照this post表的指示进行操作,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'
    ],
]

但我不断收到这个错误

17 /Users/Shared/dev/php/toters-api/vendor/laravel/framework/src/Illuminate/Pipeline/Pipeline.php(148): App\Http\Middleware\WeakEtagMiddleware->handle(Object(Illuminate\Http\Request), Object(Closure))

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,如果我从上述配置中删除了默认设置,则它看起来像这样：

'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'
    ],
]

我得到这个错误

因此,从错误消息看来,Predis只是在忽略我的集群配置并直接从默认读取,而default不知道如何处理我的集群Redis数据存储.想法？

解决方法:

搜索和调试后,这就是它起作用的原因：

'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：在上述问题中,配置中的一个明显错误是我将主机和端口组合在一起,并在此处进行了修复.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：我按照以下说明创建了集群：https://redis.io/topics/cluster-tutorial#creating-the-cluster

研究方法论

由于这个事实：
1.缺少有关laravel / predis的文档
2.堆栈溢出的大多数答案都是这样的：在谷歌搜索之后,这是对我有用的,但对发生的事情没有太多解释

我认为我可以通过显示如何找到上述答案来提供一些帮助.

1)解决错误问题

解决此错误

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.整个谷歌搜索都没有给我任何清晰的画面,因此我决定在代码中使用xdebug和dive.注意：我在一个文档中打印了错误堆栈跟踪信息(如上问题所示),我用它作为鸟瞰图来指导我完成调试步骤(例如,在每次打印输出时都跳入/移入/移出等)在单独的文档中,并将其与我的config / database.php进行比较,以作为健全性检查/调试指南针).

经过挖掘和打印后,我发现了：

[ *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.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

并且我意识到格式是错误的,所以我不应该将主机AND端口放在相同的env变量中.

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

那解决了我的第一个问题.

2)解决其他问题

修复以上问题后,我得到了

CLUSTERDOWN Hash slot not served

这很容易,只是搜索错误消息而已(因为错误消息显然是本机redis错误消息,而不是像predis错误消息那样的一些隐秘的库包装器)..我发现this answer.

其余的很容易.
