valkey-cli 命令

常用示例

说明

valkey-cli is the command-line interface for interacting with a Valkey server. It provides both an interactive REPL mode for exploring data and a non-interactive mode for scripting and automation. The client uses the same protocol as Redis, making it compatible with existing Redis workflows. Commands can be passed directly on the command line or piped from files and other programs. The client supports cluster mode for connecting to sharded deployments, database selection, authentication, and TLS connections.
