如何让 Laravel 与 AWS 上的 Redis 集群一起工作

abb*_*ood 2 php redis laravel predis laravel-5.4

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

/*

| Redis is an open source, fast, and advanced key-value store that also

            'password' => env('REDIS_PASSWORD', null),

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，使其看起来像这样：

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

    'clusters' => [

因此，从错误消息看来，Predis 只是忽略了我的集群配置并直接从默认值读取，而默认值不知道如何处理我的集群 Redis 数据存储。想法？

在搜索和调试之后，这就是使它工作的原因：

'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' => [

研究方法论

由于以下事实： 1. 缺少关于此的 laravel/predis 文档 2. 关于堆栈溢出的大多数答案都在这些方面：在谷歌搜索和搜索之后..这对我来说是有效的，没有对发生的事情进行太多解释在

我想我可以通过展示我如何找到上述答案来提供一些帮助。

1）解决错误问题

为了解决这个bug

local.ERROR：Symfony\Component\Debug\Exception\FatalThrowableError：类型错误：传递给 Predis\Connection\Parameters::__construct() 的参数 1 必须是数组类型，给定整数，在 /Users/Shared/dev/ 中调用php/toters-api/vendor/predis/predis/src/Connection/Factory.php 在 /Users/Shared/dev/php/toters-api/vendor/predis/predis/src/Connection/Parameters.php 中的第 164 行： 34 堆栈跟踪：

我意识到我的 config/database.php 格式完全错误。谷歌搜索遍也没给我任何清晰的画面，所以我决定用了XDebug和下潜到代码。注意：我在一个文档中打印了错误堆栈跟踪（显示在上面的问题中），我用它作为鸟瞰图来指导我完成调试步骤（即在始终打印输出的同时跨过/进入/退出等）在一个单独的文档中，并将其与我的 config/database.php 作为完整性检查/调试指南针进行比较）。

在挖掘和打印之后，我遇到了这个：

我将其与我的 .env 文件的内容进行了比较：

REDIS_CONTENT_HOST=127.0.0.1:7002

我意识到格式是错误的，我不应该将主机和端口放在同一个环境变量中..所以我把它改成这样：

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

这解决了我的第一个问题。

2）解决其他问题

解决上述问题后，我得到了这个

未提供 CLUSTERDOWN 哈希槽

这很容易，只需在谷歌上搜索错误消息（因为错误消息显然是本机 redis 错误消息，而不是一些像 predis 错误消息这样的神秘库包装器）。我找到了这个答案。

其余的很容易。
