Facing issues while trying to setup redis sentinel

[sruthi kypa]

Hi everyone,

I am new to redis and exploting it to see if it meets our requirement. We are looking for a highly available distributed cache for our application.

While redis have master-slave replication, from my understanding sentinel provides automatic failover. 

1) Are there any other better alternatives to Sentinel?

2) Also is sentinel considered to be production ready?

I havent seen much resources on internet to debug issues while installing sentinel. Can someone please provide any resources?

My Setup (very Simple):

Redis: 1 Master 2 slaves

Sentinel: 3 on the same vms as redis nodes.

I have a very basic configuration on sentinel.conf.

I see only one of my sentinels are able to find the slaves and none of the sentinels discovered each other. Not sure whats wrong. I have used the same config before and it worked. Is there any way to debug this?

Also my failover scenario are not working as expected. I see no way to understand whats going wrong?

Can someone please help me here? Any kind of info would be appreciated!

Thanks,

Sruthi

Redis backed by sentinel is highly available but not distributed.

I think you should try to use Redis cluster instead of Redis Sentinel.
