Is redis a server or a database?
Redis is both a server, providing network connection and request processing, and a database, supporting in-memory data storage and fast data retrieval operations. Its features include in-memory storage, rich data types, network communications, and high availability, making it suitable as both a server and a database.
Redis: server or database?
Redis (Remote Dictionary Server) is both a server and a database.
Server
As a server, Redis provides a network service for processing requests from clients. Clients can connect to the Redis server through the network and use Redis commands to manipulate data. The Redis server is responsible for processing these requests and returning corresponding results.
Database
As a database, Redis provides a mechanism for storing and retrieving data. Redis uses memory as data storage and supports various data types, including strings, hashes, sets, lists, and ordered sets. These data types enable Redis to store and organize various types of data and support fast retrieval operations.
Characteristics of Redis
Redis has the following characteristics, making it suitable both as a server and as a database:
- Memory storage: Redis uses memory as data storage, which enables it to provide extremely fast read and write speeds.
- Rich data types: Redis supports a variety of data types, which enables it to adapt to various application scenarios.
- Network communication: Redis provides services over the network, allowing clients to access data remotely.
- High availability: Redis can be configured as a high-availability cluster to improve data reliability and availability.
Therefore, Redis can act as a server and database at the same time, providing efficient network connection and data storage solutions for various application scenarios.

How to build the redis cluster mode
Apr 10, 2025 pm 10:15 PM
Redis cluster mode deploys Redis instances to multiple servers through sharding, improving scalability and availability. The construction steps are as follows: Create odd Redis instances with different ports; Create 3 sentinel instances, monitor Redis instances and failover; configure sentinel configuration files, add monitoring Redis instance information and failover settings; configure Redis instance configuration files, enable cluster mode and specify the cluster information file path; create nodes.conf file, containing information of each Redis instance; start the cluster, execute the create command to create a cluster and specify the number of replicas; log in to the cluster to execute the CLUSTER INFO command to verify the cluster status; make
How to clear redis data
Apr 10, 2025 pm 10:06 PM
How to clear Redis data: Use the FLUSHALL command to clear all key values. Use the FLUSHDB command to clear the key value of the currently selected database. Use SELECT to switch databases, and then use FLUSHDB to clear multiple databases. Use the DEL command to delete a specific key. Use the redis-cli tool to clear the data.
How to use the redis command
Apr 10, 2025 pm 08:45 PM
Using the Redis directive requires the following steps: Open the Redis client. Enter the command (verb key value). Provides the required parameters (varies from instruction to instruction). Press Enter to execute the command. Redis returns a response indicating the result of the operation (usually OK or -ERR).
How to read redis queue
Apr 10, 2025 pm 10:12 PM
To read a queue from Redis, you need to get the queue name, read the elements using the LPOP command, and process the empty queue. The specific steps are as follows: Get the queue name: name it with the prefix of "queue:" such as "queue:my-queue". Use the LPOP command: Eject the element from the head of the queue and return its value, such as LPOP queue:my-queue. Processing empty queues: If the queue is empty, LPOP returns nil, and you can check whether the queue exists before reading the element.
How to use redis lock
Apr 10, 2025 pm 08:39 PM
Using Redis to lock operations requires obtaining the lock through the SETNX command, and then using the EXPIRE command to set the expiration time. The specific steps are: (1) Use the SETNX command to try to set a key-value pair; (2) Use the EXPIRE command to set the expiration time for the lock; (3) Use the DEL command to delete the lock when the lock is no longer needed.
How to read the source code of redis
Apr 10, 2025 pm 08:27 PM
The best way to understand Redis source code is to go step by step: get familiar with the basics of Redis. Select a specific module or function as the starting point. Start with the entry point of the module or function and view the code line by line. View the code through the function call chain. Be familiar with the underlying data structures used by Redis. Identify the algorithm used by Redis.
How to solve data loss with redis
Apr 10, 2025 pm 08:24 PM
Redis data loss causes include memory failures, power outages, human errors, and hardware failures. The solutions are: 1. Store data to disk with RDB or AOF persistence; 2. Copy to multiple servers for high availability; 3. HA with Redis Sentinel or Redis Cluster; 4. Create snapshots to back up data; 5. Implement best practices such as persistence, replication, snapshots, monitoring, and security measures.
How to use the redis command line
Apr 10, 2025 pm 10:18 PM
Use the Redis command line tool (redis-cli) to manage and operate Redis through the following steps: Connect to the server, specify the address and port. Send commands to the server using the command name and parameters. Use the HELP command to view help information for a specific command. Use the QUIT command to exit the command line tool.
