【php-fpm问题】有经验的老手进来看看,谢谢。

Jun 23, 2016 pm 02:06 PM

服务是nginx+php-fpm,最近上了另一个版本的php-fpm,引入了一个问题:

post上传Multipart文件表单,php-fpm会写临时文件,但临时文件很多不会被清理掉,这在以前是没有发现过的,导致最后目录下20多万临时文件,php-fpm进程全部D状态等待磁盘了。

目前临时解决方案是crontab定时清理5分钟前的临时文件,但没有解决根源问题,根据日志大致确定请求量没有丢失,只是临时文件没有unlink掉的问题,很费解。

有人遇过此类线上问题吗? 谢谢。

上传文件至临时目录后,不是应该执行move_uploaded_file到最终目录嘛?你是调用这个函数时,并没有移动成功?还是将临时文件目录设置成了你的文件上传最终目录?

呵呵, 是php.ini里的一项配置问题, 如果用户连接在php执行期间断开, 会导致nginx->php连接断开,如果没有配置选项,那么php将立即终止而不是等待脚本执行完全终止,导致临时文件遗留。

有空可以帮我搞搞伪静态啊,对apache+ngix配置的服务器,伪静态不会写

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. 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,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Explain late static binding in PHP (static::). Explain late static binding in PHP (static::). Apr 03, 2025 am 12:04 AM

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
