service nginx stop systemctl stop nginx
Start
service nginx start systemctl start nginx
Restart
service nginx reload systemctl restart nginx
Automatically run when the system starts
systemctl enable nginx
Disable automatic running with system startup
systemctl disable nginx
Knowledge point expansion:
First use the configuration file to start nginx. Command:
nginx -c /usr/local/nginx/conf/nginx.conf
Restart the service: service nginx restart
\1. Stop or shut down Nginx quickly: nginx -s stop
\2. Stop or shut down Nginx normally: nginx -s quit
\3. Configuration file modification and reloading command: nginx -s reload
The above is the detailed content of How to shut down, restart, and start nginx. For more information, please follow other related articles on the PHP Chinese website!

NGINX can be used to serve files and manage traffic. 1) Configure NGINX service static files: define the listening port and file directory. 2) Implement load balancing and traffic management: Use upstream module and cache policies to optimize performance.

NGINX is suitable for handling high concurrency and static content, while Apache is suitable for dynamic content and complex URL rewrites. 1.NGINX adopts an event-driven model, suitable for high concurrency. 2. Apache uses process or thread model, which is suitable for dynamic content. 3. NGINX configuration is simple, Apache configuration is complex but more flexible.

NGINX and Apache each have their own advantages, and the choice depends on the specific needs. 1.NGINX is suitable for high concurrency, with simple deployment, and configuration examples include virtual hosts and reverse proxy. 2. Apache is suitable for complex configurations and is equally simple to deploy. Configuration examples include virtual hosts and URL rewrites.

The purpose of NGINXUnit is to simplify the deployment and management of web applications. Its advantages include: 1) Supports multiple programming languages, such as Python, PHP, Go, Java and Node.js; 2) Provides dynamic configuration and automatic reloading functions; 3) manages application lifecycle through a unified API; 4) Adopt an asynchronous I/O model to support high concurrency and load balancing.

NGINX started in 2002 and was developed by IgorSysoev to solve the C10k problem. 1.NGINX is a high-performance web server, an event-driven asynchronous architecture, suitable for high concurrency. 2. Provide advanced functions such as reverse proxy, load balancing and caching to improve system performance and reliability. 3. Optimization techniques include adjusting the number of worker processes, enabling Gzip compression, using HTTP/2 and security configuration.

The main architecture difference between NGINX and Apache is that NGINX adopts event-driven, asynchronous non-blocking model, while Apache uses process or thread model. 1) NGINX efficiently handles high-concurrent connections through event loops and I/O multiplexing mechanisms, suitable for static content and reverse proxy. 2) Apache adopts a multi-process or multi-threaded model, which is highly stable but has high resource consumption, and is suitable for scenarios where rich module expansion is required.

NGINX is suitable for handling high concurrent and static content, while Apache is suitable for complex configurations and dynamic content. 1. NGINX efficiently handles concurrent connections, suitable for high-traffic scenarios, but requires additional configuration when processing dynamic content. 2. Apache provides rich modules and flexible configurations, which are suitable for complex needs, but have poor high concurrency performance.

NGINX and Apache each have their own advantages and disadvantages, and the choice should be based on specific needs. 1.NGINX is suitable for high concurrency scenarios because of its asynchronous non-blocking architecture. 2. Apache is suitable for low-concurrency scenarios that require complex configurations, because of its modular design.

mPDF
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),

DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
