Redis is a high-performance open source memory data storage system that is widely used in distributed systems. Redis supports multiple data types, such as strings, hashes, lists, sets, ordered sets, etc., and provides a wealth of commands and functions. In terms of distributed network and security, Redis also has good support and applications. This article will introduce the methods and application examples of Redis in distributed networks and security.
1. Redis implements distributed network
- Redis cluster
Redis cluster is a common way of Redis distributed network. Redis cluster supports automatic sharding and fault-tolerance mechanisms, and can provide high availability and high-performance data storage services. Redis cluster supports horizontal expansion by spreading data across multiple nodes. Each node stores part of the data and maps the data to the corresponding node through a built-in hash algorithm. Redis cluster also provides automatic fault detection and automatic data redistribution functions to ensure data consistency and availability across the entire cluster.
- Redis Sentinel
Redis Sentinel is a high availability solution in the Redis distributed network. It can monitor the status of the master node and slave nodes in the Redis cluster and automatically perform failover to ensure the high availability and reliability of the Redis cluster. Redis Sentinel monitors node status through the sentinel process. The sentinel process will periodically issue ping commands to the Redis node to detect whether the node is running normally. If a node abnormality is found, the sentinel process will automatically switch to the backup node to ensure the availability and stability of the Redis cluster. sex.
2. Redis implements security
- Redis access control
Redis supports access control functions and can restrict access to the Redis network through password authentication. Redis access password can be set by configuring the requirepass parameter in the Redis.conf file. When the client connects to Redis, it needs to provide the correct password to access the Redis server, thereby ensuring the security of the Redis network.
- Redis Data Encryption
When transmitting and storing Redis data, data encryption can be used to ensure data security and privacy. Redis supports the SSL/TLS encryption protocol. You can enable the SSL/TLS encryption function by configuring the ssl parameter in the Redis.conf file. In addition, Redis also supports many data encryption solutions based on encryption algorithms, such as AES, DES, RSA, etc. You can choose the appropriate encryption algorithm according to your needs.
3. Redis Implementation Application Example
- Cache Acceleration
Redis provides high-performance caching function, which can be used to accelerate many applications, such as Web Applications, database applications, data layer applications, etc. By caching data into memory, data reading and writing speeds can be significantly improved, response times reduced, and application performance improved.
- Distributed lock
Redis provides a distributed lock function, which can be used to control concurrent access to resources in multiple processes or threads. By using Redis distributed locks, multiple processes or threads can be prevented from accessing the same resource at the same time, thereby ensuring data consistency and integrity.
- Counter
Redis provides high-performance counter functions that can be used in many scenarios, such as counters, statistics, rankings, etc. By using Redis counters, data statistics and ranking functions can be easily implemented to support complex application scenarios.
Summary
This article introduces the methods and application examples of Redis in distributed networks and security. By using high-availability solutions such as Redis Cluster and Redis Sentinel, the availability and stability of the Redis network can be ensured; by using security measures such as Redis access control and data encryption, the security of the Redis network can be ensured; by using Redis cache acceleration, distributed Application examples such as locks and counters can give full play to the high performance and rich functions of Redis to meet various complex application requirements.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
