如何隐藏掉Nginx的版本号
最近新学习了一个命令curl,里面有一个参数-I可以查看到网站使用的是哪种服务器,比如:
zhangxiaoliudeMacBook-Pro-2:~ zhangxiaoliu$ curl -I http://nginx.org/
HTTP/1.1 200 OK
Server: nginx/1.9.8
Date: Fri, 18 Dec 2015 06:30:33 GMT
Content-Type: text/html; charset=utf-8
Content-Length: 8347
Last-Modified: Wed, 09 Dec 2015 15:07:16 GMT
Connection: keep-alive
Keep-Alive: timeout=15
ETag: "566843a4-209b"
Accept-Ranges: bytes
可以看得到Nginx官方现在使用的版本是1.9.8的,每个版本的nginx可能会有一些漏洞,所以,从安全的角度来说,隐藏版本号会相对安全些!
第一步:修改nginx配置文件
vim /usr/local/nginx/conf/nginx.conf (配置文件的路径由安装nginx的目录决定,每个人的并不相同,由于部分初学者不懂就会复制粘贴然后执行,后果很严重的,对于不懂的命令千万不要执行!!!),在tcp_nodelay on;后面(或前面)添加server_tokens off;
第二步:修改php-fpm配置文件
php-fpm配置文件的名字叫fastcgi.conf或fcgi.conf,vim /usr/local/nginx/conf/fastcgi.conf (和nginx.conf在同一个目录下),使用vim命令“:/SERVER_SOFTWARE”,找到:fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; 去掉“/$nginx_version”。
第三步:重新启动nginx服务
service nginx reload (reload无间断服务重启,或者使用/etc/init.d/nginx reload,/etc/init.d/里面都是服务启动脚本,是shell脚本),有人可能会说不是使用service nginxd reload ,到底是使用nginxd还是nginx,具体要看/etc/init.d/里面的服务启动脚本的名字

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.

Fibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.
