using Redis to store the session of the Tomcat cluster Some time ago, I spent a lot of time looking for a way to push the newly developed code to the production system to be able to 0 downtime, and 0 impact on the use of users. My idea is to use the cluster to fix it by notifying the load balancing Nginx, removing the Tomcat nodes from the

First, IntroductionRedis supports synchronizing data to multiple slave, a feature that is useful for improving read performance1) Master can have more than one slave2) In addition to multiple slave connected to the same master, slave can also be connected to other slave to form a graphic structure3) Master-slave replication does not block the primary, meaning that when one or more slave and master connections are replicated, master can continue to process requests from clients, whereas slave wil
