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'
],
]
但我仍然会收到此错误

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'
],
]
我收到此错误

因此，从错误消息看来，Predis只是简单地忽略了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？
答案 0 :(得分：3)
在搜索和调试后，这是使其起作用的原因：
'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，我的配置中一个明显的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
由于以下事实： 1.缺少有关laravel / predis的文档 2.关于堆栈溢出的大多数答案都是这样的：在谷歌搜索和搜索之后。这对我来说是有效的而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的方法来帮上忙。
要解决此错误
local.ERROR：Symfony \ Component \ Debug \ Exception \ FatalThrowableError： 类型错误：参数1传递给 Predis \ Connection \ Parameters :: __ construct（）必须为数组类型， 给定的整数，称为 /Users/Shared/dev/php/toters-api/vendor/predis/predis/src/Connection/Factory.php 在第164行 /Users/Shared/dev/php/toters-api/vendor/predis/predis/src/Connection/Parameters.php:34 堆栈跟踪：
我意识到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）在单独的文档中进行比较，并将其与我的config / database.php进行比较（作为健全性检查/调试指南针）。
在挖掘并打印后，我发现了这一点：
[ *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->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
我意识到格式是错误的，我不应该将主机AND端口放在相同的env变量中。所以我改成这样：
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。
解决上述问题后，我明白了
CLUSTERDOWN哈希槽未提供
这很简单，只需搜索错误消息即可（因为错误消息显然是本机redis错误消息，而不是像predis错误消息那样的一些隐秘的库包装器）..我发现{{ 3}}。
其余的很容易。
