Problem:
 
 
  

  
   
 
    
 
  hostandport only need to specify a host IP and port? All the others are directly rediscluster, right?

3 Startup_nodes = [4 {: host = "127.0.0.1",:p ort = 7000}, 5 {: host = "127.0.0.1",:p ort =& Gt 7001} 6] The startup nodes don ' t need to being all the nodes of the cluster. The important thing is, at least one node is reachable. Also Note that Redis-rb-cluster updates this list of startup nodes as soon as it's able to connect with the first node. You should expect such a behavior with any other serious client.
