, a time limit known as node timeout timeout, an important configuration option for the Redis cluster: building and using Redis clusters The first thing to build a cluster we need some Redis instances running in cluster mode. This means that the cluster is not made up of ordinary redis instances, and cluster mode needs to be configured to enable the Redis instance of cluster mode to use the cluster-specific commands and attributes. The following is a configuration file for a cluster with the few
The previous article explains the process of building the Redis cluster based on Redis cluster, and continues to explain the increase and decrease of node in the Redis cluster below. adding nodes in a cluster Let's test again, add a new node, in 2 cases, 1 as the primary node, 2 as a node from the node. Let's try this separately: Create a new 7006 node to join as a primary node:New 7006 directory, copy configuration file, modify port, start 7006 Port Redis; [Root@spg 7006]# Ps-ef | grep redis ro
