lamp和lnmp的区别
lamp 的全称是linux + apache + mysql +php
lnmp 的全称是linux + nginx + mysql + php (国外喜欢简称为LEMP,搜英文资料需要搜LEMP)
LAMP:使用的是Apache,Apache是世界是用排名第一的Web服务器软件,其几乎可以在所有广泛使用的计算机平台上运营,由于其跨平台和安全性被广泛使用,是最流行的Web服务端软件之一。
LNMP:使用的是Nginx,Nginx是一款高性能额Http和反向代理服务器,也是一个AMAP/POP3/SMTP服务器,Nginx是由Igor Sysoev为俄罗斯访问量第二的Rambler.ru站点开发的,第一个公开版本0.1.0发布于2004年10月4日,2011年6月1日,nginx 1.0.4发布。
在lamp中,php是作为apache的一个模块,被apache加载并调用。 当处理php脚本时,是由apache来完成的,而实际上我们应该说是apache的模块libphp5.so 处理的。
nginx就不一样了,nginx后面有php-fpm服务,这个php-fpm服务作为独立的服务存在,可以监听ip:port 也可以监听socket,真正处理php脚本的工作是由php-fpm来完成的,而nginx仅仅是把用户的请求发给php-fpm,然后再把php-fpm的处理结果发给用户。
再总结一下,apache因为把php模块集于一身成为一个整体,任何请求访问(静态,动态)都是apache(httpd)自己搞定的, 而nginx仅仅是一个传递的角色。它可以处理静态(图片,js,css等),但php相关的就得由后面的php-fpm来处理。
扩展资料:
1、LNMP方式的优点:占用VPS资源较少,Nginx配置起来也比较简单,利用fast-cgi的方式动态解析PHP脚本。缺点:php-fpm组件的负载能力有限,在访问量巨大的时候,php-fpm进程容易僵死,容易发生502 bad gateway错误。
2、基于 LAMP 架构设计具有成本低廉、部署灵活、快速开发、安全稳定等特点,是 Web 网络应用和环境的优秀组合。若是服务器配置比较低的个人网站,当然首选 LNMP 架构。当然,在大流量的时候。把Apache和Nginx结合起来使用,也不失为一个不错选择。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

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),
