Redis on openEuler 24.03

Redis is a high-performance, in-memory key-value data store designed for speed and flexibility. Unlike traditional databases, Redis primarily stores data in RAM, allowing microsecond-level read/write operations, making it ideal for latency-sensitive applications. It supports a rich set of data structures, including strings, hashes, lists, sets, sorted sets, bitmaps, and HyperLogLogs, enabling complex use cases like leaderboards, geospatial indexing, and real-time analytics. Redis ensures durability through optional persistence mechanisms: RDB (snapshotting) and AOF (append-only file), which save data to disk for recovery. It also offers high availability via replication, automatic failover with Redis Sentinel, and horizontal scaling through Redis Cluster, which partitions data across multiple nodes. Please enter the root user first: sudo su - Check if the Redis service is running: # systemctl status redis Start Redis service: # systemctl start redis Restart Redis service: # systemctl restart redis Stop Redis service: # systemctl stop restart redis
