Redis's master-slave copy strategy is realized through its persistent RDB file, the process is to dump out Rdb file, Rdb file to Slave, and then synchronize the operation of the dump to slave in real time. The following is an article on the principle of Redis reproduction, the author of the article for Sina Weibo Tianqi classmate (@ Rocking Bach). This article discusses the replication capabilities of the Redis and the advantages and disadvantages of the Redis replication mechanism itself, as we

Because the cluster involves Server Load balancer processing and requests need to be distributed among different machines, domain name resolution is required. In addition, machines in the cluster need to share the site configurati
