Redis Installation and use

Redis is a server for memory-storage data structures, typically using Redis as a cache server, and Redis supports not only simple keyvalue string structures, but also map, List, set data structures, and high read performance. In a distributed environment, the Redis storage session is also used to achieve the purpose of sharing the session. Redis data is stored in memory, and as the amount of data grows, so does the memory burden, which typically requires a separate server in the production environment to support and avoid Redis impacting web App service performance. #下载Redis, unzip, compile and install
