为 Redis 实例配置连接重试

Question

I plan to move my web site to a cloud one. I've been told there is some micro-interruptions in some services.

Therefore I'd like to configure a connection retry for the redis cache set up.

I'm using Symfony 4.2 with this configuration

framework:
  cache:
    app: cache.adapter.redis
    default_redis_provider: '%env(REDIS_URL)%'

Is there any way to configure the retry_interval option of redis in Symfony ?

EDIT : including precisions of @simon.ro

Answer 1

Redis has an option retry_interval which you can specify at connect-time. You should check the documentation of the redis connecting library you are using.

Answer 2

The default_redis_provider is a DSN that will be parsed with parse_url function

So you can add parameters into query string like this :

default_redis_provider: 'redis://u:pass@localhost/2:6379?retry_interval=300&timeout=10&read_timeout=30&tcp_keepalive=10'

path of url /2 is the dbindex of redis
