Centos与Debian PHP环境变量问题。

Jun 23, 2016 pm 02:17 PM

通过PHP shell_exec来执行 shell脚本。
shell脚本中有执行到python,

python脚本,os.path.expanduser('~')
在Centos系统是取到 /root/
而Debian系统是取到 /home/www

PHP的真实用户是www的,但上面shell脚本是以root权限运行的。


Centos下是取到root用户主目录
/root/

而Debian是取到www用户主目录
/home/www

现在怎么保持一致,有些晕了。

你把文件chown 一下,
用php里面的get_current_user,就应该都是www了

因为php执行时,是web server的当前用户,所以和你直接shell里面的用户是不一致的,如果你想保持一致的话,就别用~,或者在shell中执行python中使用www用户

其实也说明Centos中php执行的当前用户是root 。。。

这个没关系。

有些差错,已解决了,是一致的。
现在都是www用户了,
php脚本(www用户) -> shell_exec() -> C(提权root用户) -> shell脚本(root用户) -> python(反而是www用户)
不太明白python怎么是取到www的主目录。
shell id -u 是0,也就是root的,按道理应该取到root的主目录吧。
python反而取到真实的php用户www的主目录。

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

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.
