问题描述

我已经在 Amazon ElastiCache 上为缓存设置了 redis-cluster，使用 Laravel 5.5 和 Predis 包，我收到以下错误.

PredisClientException: 在 vendor/predis/predis/src/Connection/Aggregate/RedisCluster.php:337 中的池中没有可用的连接

16 {main}

我使用的技术栈:

PHP7.0
Laravel5.5
操作系统(Debian GNU/Linux 9.6 (stretch))，9.6 版

我在 config/database.php 中尝试了以下配置:

redis=>['客户' =>'predis','选项' =>['集群' =>'redis',],'集群' =>['默认' =>[['主机' =>环境('REDIS_CLUSTER_HOST'，'本地主机')，'密码' =>env('REDIS_CLUSTER_PASSWORD', null),'端口' =>环境('REDIS_CLUSTER_PORT'，6379)，'数据库' =>0,],],'缓存' =>[['主机' =>环境('REDIS_CLUSTER_HOST'，'本地主机')，'密码' =>env('REDIS_CLUSTER_PASSWORD', null),'端口' =>环境('REDIS_CLUSTER_PORT'，6379)，'数据库' =>0,],],]]

我也试过 timeout => 0|5|60 但每次我都遇到同样的错误.

任何帮助将不胜感激！

解决方案

这在我们的环境中起作用:

 'redis' =>['集群' =>真的，'客户' =>'predis','选项' =>['集群' =>'redis','参数' =>['方案' =>env('REDIS_SCHEME', 'tcp'),'主机' =>环境('REDIS_HOST'，'本地主机')，'密码' =>env('REDIS_PASSWORD', null),'端口' =>环境('REDIS_PORT'，6379)，'数据库' =>0,'超时' =>15、],],'集群' =>['默认' =>['方案' =>env('REDIS_SCHEME', 'tcp'),'主机' =>环境('REDIS_HOST'，'本地主机')，'密码' =>env('REDIS_PASSWORD', null),'端口' =>环境('REDIS_PORT'，6379)，'数据库' =>0,'超时' =>15、],],],

基于此处找到的信息:https://github.com/nrk/predis/issues/480 - 但还需要复制选项中的所有默认"配置值 -> 参数组

REDIS_HOST，指向 AWS elasticache 的 redis 集群中的配置端点.

I've setup redis-cluster on Amazon ElastiCache for cache, using Laravel 5.5 and Predis package, I get the following error.

PredisClientException: No connections available in the pool in vendor/predis/predis/src/Connection/Aggregate/RedisCluster.php:337

Technical stack I used:

PHP7.0
Laravel5.5
OS (Debian GNU/Linux 9.6 (stretch)), Release 9.6

I tried the following configs in config/database.php:

redis=> [
'client'  => 'predis',
        'options' => [
            'cluster' => 'redis',
        ],
        'clusters' => [
            'default' => [
                [
                    'host' => env('REDIS_CLUSTER_HOST', 'localhost'),
                    'password' => env('REDIS_CLUSTER_PASSWORD', null),
                    'port' => env('REDIS_CLUSTER_PORT', 6379),
                    'database' => 0,
                ],
            ],
            'cache' => [
                [
                    'host' => env('REDIS_CLUSTER_HOST', 'localhost'),
                    'password' => env('REDIS_CLUSTER_PASSWORD', null),
                    'port' => env('REDIS_CLUSTER_PORT', 6379),
                    'database' => 0,
                ],
            ],
        ]
]

I also tried with timeout => 0|5|60 but every time I get the same error.

Any help would be highly appreciated!

解决方案

This is working in in our env:

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

         'client' => 'predis',

         'options' => [
             'cluster' => 'redis',
             'parameters' => [
                 'scheme'   => env('REDIS_SCHEME', 'tcp'),
                 'host'     => env('REDIS_HOST', 'localhost'),
                 'password' => env('REDIS_PASSWORD', null),
                 'port'     => env('REDIS_PORT', 6379),
                 'database' => 0,
                 'timeout' => 15,
              ],
         ],

         'clusters' => [

             'default' => [
                 'scheme'   => env('REDIS_SCHEME', 'tcp'),
                 'host'     => env('REDIS_HOST', 'localhost'),
                 'password' => env('REDIS_PASSWORD', null),
                 'port'     => env('REDIS_PORT', 6379),
                 'database' => 0,
                 'timeout' => 15,
             ],
         ],
     ],

Based on info found here: https://github.com/nrk/predis/issues/480 - but needed to also replicate all 'default' config values in the options -> parameters group

REDIS_HOST, is pointing to the configuration endpoint in AWS elasticache's redis cluster.
