Master-slave replication configuration for redisI. Principles Redis's master-slave replication function is very powerful. One master can have multiple slave instances, and one slave can have multiple slave instances. In this way, a powerful multi-level server cluster archite

-UML class diagrams are often used to describe the static structure between classes when describing the design mode. The purpose of this article is to allow the readers to understand the UML class diagrams and to figure out several relationships in the UML class diagrams. -In the subsequent design model learning process, only these two points are adequate. More advanced is beyond the scope of this article. Johnconnor design pattern note series directory Johnconnor design patterns Note (I) Wha

In Redis, users can have one server replicate (replicate) another server by executing the slaveof command or setting the slaveof option, which we call the replicated server as the primary server (master), The server that replicates the primary server is referred to as the slave server (slave).Suppose you now have two Redis servers with addresses 127.0.0.1:6379 and 127.0.0.1:12345, if we send the following command to the server 127.0.0.1:12345:127.0.0.

First, MySQL master (called Master) from (called slave) Copy principle: (1). master records data changes to the binary log (binary log), which is the Log-bin specified file (These records are called binary log events binary log event)(2). Slave copy Master's binary log events to its relay logs (relay log)(3). Slave redo the event in the relay log, changing the d
