Clustering Redis with AWS Elasticache

Hi,

Can you help us?

We are trying to configure Redis Object Cache on cluster mode, but using AWS Elasticache

https://aws.amazon.com/elasticache/redis

We are trying many solutions but, we get the same results.

Connection Exception: SELECT failed: ERR SELECT is not allowed in cluster mode [tcp://redis-cluster02-0001-002.59bqaj.0001.use1.cache.amazonaws.com:6379] (Predis\Connection\ConnectionException)

or

Connection Exception: Couldn’t map cluster keyspace using any provided seed (RedisClusterException)

Using these setup

define( ‘WP_REDIS_CLUSTER’, [
‘tcp://redis-cluster02-0001-001.59bqaj.0001.use1.cache.amazonaws.com:6379?database=1&alias=node-01’,
‘tcp://redis-cluster02-0001-002.59bqaj.0001.use1.cache.amazonaws.com:6379?database=1&alias=node-02’,
] );

or

define( ‘WP_REDIS_SHARDS’, [
‘tcp://redis-cluster02-0001-001.59bqaj.0001.use1.cache.amazonaws.com:6379?database=1&alias=shard-01’,
‘tcp://redis-cluster02-0001-002.59bqaj.0001.use1.cache.amazonaws.com:6379?database=1&alias=shard-02’,
] );
