Proxy Server Fundamentals Proxy servers act as intermediaries between clients and backend services. In Nginx, reverse proxy configuration enables request forwarding, response buffering, and header manipulation. This guide covers practical implementations for routing traffic to HTTP and non-HTTP upstream servers. Basic Request Forwarding Configu ...

To support resumable and chunked downloads, the file server must handle HTTP Range requests. We configure Nginx as a reverse proxy in front of FastDFS, enabling the slice module for efficient caching of range requests. Installing Nginx with Slice Module: The slice module is required for splitting large files into smaller pieces during caching. ...

System Preparation and Dependencies Before deploying the web server, ensure the underlying operating system meets specific network and security requirements. Verify network connectivity and package manager functionality. Security modules such as SELinux and firewall rules often interfere with service binding and should be configured appropriate ...

Nginx Configuration File Locations: The location of Nginx configuration files varies depending on the installation method. Source Code Compilation: Typically found in /usr/local/nginx/conf directory. Yum Installation: Usually in /etc/nginx/ directory (main configuration file) and /etc/nginx/conf.d directory. Docker Container: Generally located ...

Environment and Nginx Installation Assume a CentOS 7 environment targeting Nginx 1.18+. Begin by configuring the official package repository and installing the binary. Ensure the http_ssl_module is compiled into the binary, as it is mandatory for TLS termination. # Install repository management utility yum install -y yum-utils # Create reposit ...

Verifying Stream Module Support The Nginx Stream module operates at Layer 4 (TCP/UDP), allowing for efficient traffic forwarding and load balancing outside of the standard HTTP context. Before attempting configuration, verify if your Nginx binary includes the module by executing the following command: nginx -V 2>&1 | grep --color -- '--w ...

HTTP Status Codes HTTP response status codes are three-digit numbers that indicate the outcome of a request. Common status codes include: 200: Success 301: Permanent redirect 302: Temporary redirect 304: Browser cache (not modified) 403: Forbidden (permission denied) 404: Resource not found 500: Internal server error (server code error) 502: B ...

Nginx Concurrency Estimation Estimation formula: {（?G）*1024-system} / request size ?G: Memory size (in GB) 1024: Standard memory capacity conversion factor (MB to GB) system: Memory occupied by the system and services, plus reserved memory request size: Size of a request, typically in KB for static content or MB for dynamic content A 16-c ...

Server Environment Setup Host: 4-core 8GB CentOS 7.9 virtual machine (verify with cat /etc/redhat-release) Dependencies: Anaconda, Python 3.8, uWSGI, Nginx Python 3.8 Compilation and Installation Update Yum Repositories First back up default CentOS base repo: cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak Replace wi ...

Core Concepts and Architecture Nginx is a high-performance HTTP server and reverse proxy developed by Igor Sysoev. It efficiently handles concurrent connections and serves as a reliable alternative to traditional web servers under heavy load. Beyond web serving, it functions as an IMAP/POP3/SMTP proxy, making it a versatile tool for modern infr ...
