redis-cli 命令

常用示例

说明

redis-cli is the command-line interface for Redis, an in-memory data structure store used as database, cache, and message broker. It provides interactive and scripted access to Redis servers. In interactive mode (no command specified), redis-cli presents a prompt for entering commands. Commands follow Redis protocol: command name followed by arguments, with responses displayed immediately. Common operations include key-value storage (GET, SET, DEL), lists (LPUSH, RPOP), sets (SADD, SMEMBERS), hashes (HSET, HGET), and pub/sub messaging (PUBLISH, SUBSCRIBE). The tool supports cluster mode, sentinel connections, and various debugging and monitoring features for Redis administration.
