Redis?的作者antirez(Salvatore Sanfilippo)同学发表了一篇名为Redis?宣言Redis Manifesto)的文章,文中列举了Redis 的七个原则,以向大家阐明Redis 的思想

  1. Redis 是一个操作数据结构的语言工具,它提供基于TCP的协议以操作丰富的数据结构。在Redis中,数据结构这个词的意义不仅表示在某种数据结构上的操作,更包括了结构本身及这些操作的时间空间复杂度。
  2. Redis 定位于一个内存数据库,正是由于内存的快速访问特性,才使得Redis能够有如此高的性能,才使得Redis能够轻松处理大量复杂的数据结构,Redis会尝试其它的存储方面的选择,但是永远不会改变它是一个内存数据库的角色。
  3. Redis 使用基础的API操作基础的数据结构,Redis的API与数据结构一样,都是一些最基础的元素,你几乎可以将任何信息交互使用此API格式表示。作者调侃说,如果有其它非人类的智能生物存在,他们也能理解Redis的API。因为它是如此的基础。
  4. Redis 有着诗一般优美的代码,经常有一些不太了解Redis 原则的人会建议Redis采用一些其它人的代码,以实现一些Redis 未实现的功能,但这对我们来说就像是非要给《红楼梦》接上后四十回一样。(作者此处用了莎士比亚的比喻)
  5. Redis 始终避免复杂化,我们认为设计一个系统的本质,就是与复杂化作战。我们不会为了一个小功能而往源码里添加上千行代码,解决复杂问题的方法就是让复杂问题永远不要提复杂的问题。
  6. Redis 支持两个层成的API,第一个层面包含部分操作API,但它支持用于分布式环境下的Redis。第二个层面的API支持更复杂的multi-key操作。它们各有所长,但是我们不会推出两者都支持的API,但我们希望能够提供实例间数据迁移的命令,并执行multi-key操作。
  7. 我们以优化代码为乐,我们相信编码是一件辛苦的工作,唯一对得起这辛苦的就是去享受它。如果我们在编码中失去了乐趣,那最好的解决办法就是停下来。我们决不会选择让Redis不好玩的开发模式。

How to build the redis cluster mode 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 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 read redis queue 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 configure Lua script execution time in centos redis How to configure Lua script execution time in centos redis Apr 14, 2025 pm 02:12 PM

On CentOS systems, you can limit the execution time of Lua scripts by modifying Redis configuration files or using Redis commands to prevent malicious scripts from consuming too much resources. Method 1: Modify the Redis configuration file and locate the Redis configuration file: The Redis configuration file is usually located in /etc/redis/redis.conf. Edit configuration file: Open the configuration file using a text editor (such as vi or nano): sudovi/etc/redis/redis.conf Set the Lua script execution time limit: Add or modify the following lines in the configuration file to set the maximum execution time of the Lua script (unit: milliseconds)

How to use the redis command line 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.

How to implement redis counter How to implement redis counter Apr 10, 2025 pm 10:21 PM

Redis counter is a mechanism that uses Redis key-value pair storage to implement counting operations, including the following steps: creating counter keys, increasing counts, decreasing counts, resetting counts, and obtaining counts. The advantages of Redis counters include fast speed, high concurrency, durability and simplicity and ease of use. It can be used in scenarios such as user access counting, real-time metric tracking, game scores and rankings, and order processing counting.

How to set the redis expiration policy How to set the redis expiration policy Apr 10, 2025 pm 10:03 PM

There are two types of Redis data expiration strategies: periodic deletion: periodic scan to delete the expired key, which can be set through expired-time-cap-remove-count and expired-time-cap-remove-delay parameters. Lazy Deletion: Check for deletion expired keys only when keys are read or written. They can be set through lazyfree-lazy-eviction, lazyfree-lazy-expire, lazyfree-lazy-user-del parameters.

How to optimize the performance of debian readdir How to optimize the performance of debian readdir Apr 13, 2025 am 08:48 AM

In Debian systems, readdir system calls are used to read directory contents. If its performance is not good, try the following optimization strategy: Simplify the number of directory files: Split large directories into multiple small directories as much as possible, reducing the number of items processed per readdir call. Enable directory content caching: build a cache mechanism, update the cache regularly or when directory content changes, and reduce frequent calls to readdir. Memory caches (such as Memcached or Redis) or local caches (such as files or databases) can be considered. Adopt efficient data structure: If you implement directory traversal by yourself, select more efficient data structures (such as hash tables instead of linear search) to store and access directory information
