How to implement cluster deployment in php projects
How to implement cluster deployment for PHP projects: 1. Use a load balancer to allocate requests to different servers so that service requests can be evenly distributed to each server to achieve balanced load; 2. Use distributed The file system ensures the consistency and accuracy of data when multiple servers access the same data, further improving the stability of the system; 3. Using a database cluster to distribute a database to multiple servers improves the performance and availability of the database. .
Operating system for this tutorial: Windows 10 system, php8.1.3 version, Dell G3 computer.
How to implement cluster deployment for PHP projects:
1. How to implement cluster deployment
①: Load balancer
Load Balancer is the core part of cluster deployment. Load balancing distributes requests to different servers so that service requests can be evenly distributed to each server, thereby achieving the purpose of balancing the load. Commonly used load balancing algorithms include polling, least connections, hashing, etc.
②: Distributed file system
Distributed file system means that in a cluster environment, multiple servers share the same data and can modify the shared data at any time. By using a distributed file system, data consistency and accuracy can be ensured when multiple servers access the same data, further improving system stability.
③: Database cluster
Sharing a database between multiple servers will cause bottlenecks. By using a database cluster, a database can be distributed to multiple servers, improving database performance and availability.
2. Commonly used cluster deployment tools
①: Nginx
Nginx is a lightweight and high-performance web server, and it is also a reverse Proxy servers, load balancers, and caching servers. Load balancing and reverse proxy functions can be achieved by using Nginx.
②：MySQL Cluster
MySQL Cluster is the cluster version of the MySQL database system. Compared with the stand-alone version of MySQL, MySQL Cluster provides better availability and high performance.
③: Redis Cluster
Redis is a high-performance key-value pair storage database. By using Redis Cluster, the entire Redis cluster can be divided into multiple sub-clusters to improve performance and availability.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
