HomeBackend DevelopmentPHP Tutorial实战在Ubuntu上配置Nginx+PHP+MySQL环境

Nginx是一款近些年来日益流行的 高性能的HTTP和反向代理服务器,同时也是一个IMAP/POP3/SMTP 代理服务器 ,他的发音是"Engine X"

(怪不得我感觉之前读的那么别扭,原来读的不对。。)

,今天刚好又拿到一个ec2配额,在ubuntu上尝试了一下部署这套环境

对ec2配置的提示 如果你需要在ec2上做web服务,记得到安全组的入站设置内允许80端口通讯

1.安装FastCGI

FastCGI是负责Nginx解析php的一个模块,有关FastCGI的介绍请看下文,下文引自 博客园 - Ubuntu中Nginx的安装与配置

Nginx完全是轻量级的,必须借助第三方的FastCGI处理器才可以对PHP进行解析,因此其实这样看来Nginx是非常灵活的,它可以和任何第三方提供解析的处理器实现连接从而实现对PHP的解析(在nginx.conf中很容易设置)。Nginx可以使用spwan-fcgi。在早期版本中需要安装lighttpd,但是在9.10版本以后直接安装spawn-fcgi就可以。

安装spwan-fcgi可以用ubuntu自带的 apt-get 来安装

sudo apt-get install spawn-fcgi  

2.安装与启动nginx

同样道理安装nginx也可以用 apt-get 来进行安装

sudo apt-get install nginx  

按照此方式安装后,nginx的各个文件位置大概如下

配置文件目录: /etc/nginx

每个虚拟主机的配置文件的目录: /etc/nginx/sites-available

启动程序文件: /usr/sbin/nginx

日志文件( access.log 和 error.log ): /var/log/nginx

启动脚本: /etc/init.d/nginx

虚拟主机默认目录: /usr/share/nginx/www

安装完成后即可通过启动脚本控制nginx开关

启动: sudo /etc/init.d/nginx start

停止: sudo /etc/init.d/nginx stop

重启: sudo /etc/init.d/nginx restart

3.安装PHP、MySQL并配置PHP使之正常运行

继续使用apt-get安装php、mysql和中间件等组件

sudo apt-get install php5-cli php5-cgi mysql-server php5-mysql  

然后定位到nginx的虚拟主机配置目录,编辑 default 这个文件(记得开sudo),然后找如下代码

location ~ \.php$ {                  fastcgi_split_path_info ^(.+\.php)(/.+)$;                # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini        #       # With php5-cgi alone:        #       fastcgi_pass 127.0.0.1:9000;        #       # With php5-fpm:        #       fastcgi_pass unix:/var/run/php5-fpm.sock;        #       fastcgi_index index.php;        #       include fastcgi_params;        }

请注意,如果这步配置错误或者没有配置就会出现访问php脚本时浏览器弹出下载的问题,所以说我并不推荐在配置成功之前便将代码部署至服务器,这样很可能由于配置失误造成风险。去掉 # With php5-fpm 下面三行代码的注释并保存,然后重启nginx

sudo /etc/init.d/nginx restart  

然后定位到你的虚机主机默认目录,写一个简单的php脚本保存下,比如

<?php  phpinfo();  

然后到浏览器里访问这个脚本,如果一切正常就算成功了

PHP's Current Status: A Look at Web Development TrendsPHP's Current Status: A Look at Web Development TrendsApr 13, 2025 am 12:20 AM

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP vs. Other Languages: A ComparisonPHP vs. Other Languages: A ComparisonApr 13, 2025 am 12:19 AM

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP vs. Python: Core Features and FunctionalityPHP vs. Python: Core Features and FunctionalityApr 13, 2025 am 12:16 AM

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP: A Key Language for Web DevelopmentPHP: A Key Language for Web DevelopmentApr 13, 2025 am 12:08 AM

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP: The Foundation of Many WebsitesPHP: The Foundation of Many WebsitesApr 13, 2025 am 12:07 AM

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

What are Weak References in PHP and when are they useful?What are Weak References in PHP and when are they useful?Apr 12, 2025 am 12:13 AM

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

Explain the __invoke magic method in PHP.Explain the __invoke magic method in PHP.Apr 12, 2025 am 12:07 AM

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.
