Normally, one of our machines will not only deploy one project, so at this time we need to set up a virtual machine to map the resolution of multiple addresses.
Suppose we currently have an nginx server that has been set up and provides services through php-fpm
.
Find the configuration file address
Sometimes we don’t know where the configuration file is, and there are big differences between different versions of Linux distributions, so at this time, we need to find the location of the configuration file
<code>[root<span>@iZ28405a6nlZ</span> ~]<span># whereis nginx</span><span>nginx:</span> /usr/sbin/nginx /etc/nginx /usr/share/nginx</code>
You can find it this way I found the location of the configuration file /etc/nginx
Set the configuration file
Go into the configuration folder and find that there is a conf.d
folder inside. The configuration file inside will be loaded every time you restart. Create your domain name.conf
file in this, such as www.localhost.com.conf
The following is an example I wrote. The configuration of each server will be different. Don’t just use it
<code><span>server</span> { <span>listen</span><span>80</span>; <span>server_name</span> www.xxx.com; <span>index</span> index.html index.htm index.php; <span>root</span> /usr/share/nginx/html/xxx; <span>location</span> / { <span>try_files</span><span>$uri</span><span>$uri</span>/ /index.php?<span>$args</span>; <span>if</span> (!-e <span>$request_filename</span>){ <span>rewrite</span><span> ^/(.*)</span> /index.php <span>last</span>; } <span>root</span> /usr/share/nginx/html/markweb; <span>index</span> index.php index.html index.htm; } <span>location</span><span>~ \.php$</span> { <span>root</span> /usr/share/nginx/html/xxx; <span>include</span> fastcgi_params; <span>fastcgi_pass</span><span>127.0.0.1:9000</span>; <span>fastcgi_index</span> index.php; <span>fastcgi_param</span> SCRIPT_FILENAME /usr/share/nginx/html/markweb<span>$fastcgi_script_name</span>; <span># include fastcgi_params;</span> } <span>log_format</span> www.xxx.com <span>'<span>$remote_addr</span> - <span>$remote_user</span> [<span>$time_local</span>] <span>$request</span>'</span><span>'<span>$status</span><span>$body_bytes_sent</span><span>$http_referer</span> '</span><span>'<span>$http_user_agent</span><span>$http_x_forwarded_for</span>'</span>; <span>access_log</span> /var/log/www.xxx.com.log www.xxx.com; } </code>
to restart Then just set the corresponding domain name resolution~

The above introduces the nginx virtual machine settings, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.

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 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 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 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

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.

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.

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.
