在生产环境中,为了网站的安全访问,需要Nginx禁止一些非法访问,如恶意域名解析,直接使用IP访问网站。下面记录一些常用的配置示例:
1)禁止IP访问
如果没有匹配上server name就会找default默认,返回501错误。
server { listen 80 default_server; server_name _; return 501; }
2)通过301跳转到主页
server { listen 80 default_server; server_name _; rewrite ^(.*) http://www.jb51.com/$1 permanent; }
3)凡是请求www.jb51.com都跳转到后面域名www.yisu.com上。(需要放到server配置里)
if ($host ~ '^www.jb51.com'){ return 301 https://www.yisu.com$request_uri; }
4)Nginx限制非法域名恶意解析到本地服务器和IP访问网站
server {undefined listen 80 default_server; server_name _; return 501; }
The above is the detailed content of How to ban ip access or illegal domain name access in Nginx. For more information, please follow other related articles on the PHP Chinese website!

NGINX can improve website performance and reliability by: 1. Process static content as a web server; 2. forward requests as a reverse proxy server; 3. allocate requests as a load balancer; 4. Reduce backend pressure as a cache server. NGINX can significantly improve website performance through configuration optimizations such as enabling Gzip compression and adjusting connection pooling.

NGINXUnit simplifies application deployment with dynamic configuration and multilingual support. 1) Dynamic configuration can be modified without restarting the server. 2) Supports multiple programming languages, such as Python, PHP, and Java. 3) Adopt asynchronous non-blocking I/O model to improve high concurrency processing performance.

NGINX initially solved the C10K problem and has now developed into an all-rounder who handles load balancing, reverse proxying and API gateways. 1) It is well-known for event-driven and non-blocking architectures and is suitable for high concurrency. 2) NGINX can be used as an HTTP and reverse proxy server, supporting IMAP/POP3. 3) Its working principle is based on event-driven and asynchronous I/O models, improving performance. 4) Basic usage includes configuring virtual hosts and load balancing, and advanced usage involves complex load balancing and caching strategies. 5) Common errors include configuration syntax errors and permission issues, and debugging skills include using nginx-t command and stub_status module. 6) Performance optimization suggestions include adjusting worker parameters, using gzip compression and

Diagnosis and solutions for common errors of Nginx include: 1. View log files, 2. Adjust configuration files, 3. Optimize performance. By analyzing logs, adjusting timeout settings and optimizing cache and load balancing, errors such as 404, 502, 504 can be effectively resolved to improve website stability and performance.

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.
