Application practice of Redis in container storage
With the development and popularization of containerization technology, traditional data storage methods have faced many challenges and problems. In this context, Redis (Remote Dictionary Server) in NoSQL databases is increasingly favored by developers. Redis is an in-memory data storage system that can be persisted to disk and supports multiple data types, such as strings, hashes, lists, sets, and ordered sets. This article will explore the application practice of Redis in container storage.
1. Advantages of Redis
1. High performance
The main feature of Redis is extremely high performance, which can handle hundreds of thousands to millions of requests per second. The performance is very excellent.
2. Message Queue
Redis supports pub/sub mode, which can meet the needs of message queues and help developers write scalable, high-performance distributed applications.
3. Cache
Redis can be used as a cache to store the popular data of the website in memory, which can speed up the access speed of the website and improve the user experience.
4.Session storage
Redis can store Session in memory, improve performance, reduce database pressure, and ensure the stability and reliability of the website.
2. Application practice of Redis in container storage
1. Use Docker to build a Redis cluster
Docker is a container-based virtualization technology that can make applications Can run cleanly in different environments. Using Docker to build a Redis cluster can make the establishment of a Redis cluster simpler and more efficient. In this environment, the deployment and management of Redis are extremely convenient. You only need to use Docker commands to quickly build a Redis cluster.
2. Use Kubernetes for Redis cluster management
Kubernetes is a container orchestration and management tool that can easily expand and shrink the Redis cluster. Using Kubernetes can further simplify and optimize management operations such as the deployment and expansion of Redis clusters based on Docker.
3. Use Redis as a cache for containerized applications
In the architecture of containerized applications, using Redis as a cache layer can greatly improve the performance of the application. Deploying Redis in a container can better control the expansion and contraction of the cache, improve the cache hit rate, and reduce the response time of the application.
4. Use Redis as Session storage
In the architecture of containerized applications, the life cycle of the container is very short, which requires the use of Session storage. Using Redis as session storage can effectively solve the problem of session loss and improve the reliability and stability of applications.
3. Summary
As a high-performance NoSQL database that supports multiple data types and message queues, the application practice of Redis in container storage has been widely recognized and applied. With the help of Docker and Kubernetes, Redis cluster deployment and management are more efficient and convenient. Using Redis as cache and session storage for containerized applications can greatly improve application performance and reliability. Although Redis is widely used in container storage, in practice it still needs to be optimized and improved according to specific business scenarios.

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

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 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.

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)

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.

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.

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

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.
