Experimental environment
•A minimally installed centos 7.3 virtual machine
•Configuration: 1 core/512mb
•nginx version 1.12.2
1. Configure the hotlink website
1. Start an nginx virtual machine and configure two websites
vim /etc/nginx/conf .d/vhosts.conf
Add the following content
server { listen 80; server_name site1.test.com; root /var/wwwroot/site1; index index.html; location / { } } server { listen 80; server_name site2.test.com; root /var/wwwroot/site2; index index.html; location / { } }
2. Edit c:\windows\system32\ on the host machine drivers\etc\hosts file
192.168.204.11 site1.test.com
192.168.204.11 site2.test.com
##3 .Create the website root directory
mkdir /var/wwwroot cd /var/wwwroot mkdir site1 mkdir site2 echo -e "<h1 id="site">site1</h1><img src="/static/imghwm/default1.png" data-src="https://img.php.cn/upload/article/000/887/227/168390384638564.jpg?x-oss-process=image/resize,p_40" class="lazy" src='1.jpg' alt="How to configure Nginx anti-hotlinking" >" >> site1/index.html echo -e "<h1 id="site">site2</h1><img src="/static/imghwm/default1.png" data-src="https://img.php.cn/upload/article/000/887/227/168390384638564.jpg?x-oss-process=image/resize,p_40" class="lazy" src='http://site1.test.com/1.jpg' alt="How to configure Nginx anti-hotlinking" >" >> site2/index.html
4.Upload 1.jpg to the /var/wwwroot/site1 directory
##5.Start the nginx servicesystemctl restart nginx
netstat -anpt | grep nginx
setenforce 0
firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --reload
##2. Configure site1.test.com to prevent hotlinking
1. Edit the nginx configuration file
server { listen 80; server_name site1.test.com; root /var/wwwroot/site1; index index.html; location / { } location ~ \.(jpg|png|gif|jpeg)$ { valid_referers site1.test.com; if ($invalid_referer) { return 403; } } } server { listen 80; server_name site2.test.com; root /var/wwwroot/site2; index index.html; location / { } }
2. Restart the nginx service
systemctl restart nginx
3. On the host machine, visit
to clear the browser cache, and visit
to clear the browser cache. , visit
It can be seen that the anti-hotlinking configuration plays a role
3. Configure anti-hotlinking to return other resources
1. Edit nginx configuration file
Add a virtual host and rewrite the resources protected by anti-hotlinking
server { listen 80; server_name site1.test.com; root /var/wwwroot/site1; index index.html; location / { } location ~ \.(jpg|png|gif|jpeg)$ { valid_referers site1.test.com; if ($invalid_referer) { rewrite ^/ http://site3.test.com/notfound.jpg; #return 403; } } } server { listen 80; server_name site2.test.com; root /var/wwwroot/site2; index index.html; location / { } } server { listen 80; server_name site3.test.com; root /var/wwwroot/site3; index index.html; location / { } }Explanationlocation ~ \ .(jpg|png|gif|jpeg)$ {} is the file type for setting anti-hotlinking, separated by vertical bars |.
valid_referers site1.test.com *.nginx.org; is a whitelist, separated by spaces, and * can be used to set the pan-domain name.
if ($invalid_referer) {} is used to determine whether it matches the whitelist. If it does not match the whitelist, the content in {} will be executed.rewrite ^/ ; is a rewrite resource. If it does not meet the whitelist, it will be rewritten to this address.
return 403; means the returned status code is 403.
2. Create the site3 root directory
cd /var/wwwroot mkdir site3 echo -e "<h1 id="site">site3</h1><img src='notfound.jpg' alt="How to configure Nginx anti-hotlinking" >" >> site3/index.html3. Upload the notfound.jpg file to the /var/wwwroot/site3 directory
4. Restart nginx service
systemctl restart nginx
5. Edit c:\windows\system32\ on the host machine drivers\etc\hosts file
Add mapping to site3.test.com
192.168.204.11 site1.test.com
192.168.204.11 site2.test .com192.168.204.11 site3.test.com6. Visit
on the host machine and you can see that site1 was stolen in site2 The 1.jpg file was redirected to the notfound.jpg file on site3

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.

NGINXUnit is an open source application server that supports multiple programming languages and provides functions such as dynamic configuration, zero downtime updates and built-in load balancing. 1. Dynamic configuration: You can modify the configuration without restarting. 2. Multilingual support: compatible with Python, Go, Java, PHP, etc. 3. Zero downtime update: Supports application updates that do not interrupt services. 4. Built-in load balancing: Requests can be distributed to multiple application instances.

NGINXUnit is better than ApacheTomcat, Gunicorn and Node.js built-in HTTP servers, suitable for multilingual projects and dynamic configuration requirements. 1) Supports multiple programming languages, 2) Provides dynamic configuration reloading, 3) Built-in load balancing function, suitable for projects that require high scalability and reliability.

NGINXUnit improves application performance and manageability with its modular architecture and dynamic reconfiguration capabilities. 1) Modular design includes master processes, routers and application processes, supporting efficient management and expansion. 2) Dynamic reconfiguration allows seamless update of configuration at runtime, suitable for CI/CD environments. 3) Multilingual support is implemented through dynamic loading of language runtime, improving development flexibility. 4) High performance is achieved through event-driven models and asynchronous I/O, and remains efficient even under high concurrency. 5) Security is improved by isolating application processes and reducing the mutual influence between applications.
