While basic Nginx configurations are well-documented, this article explores more advanced techniques to enhance your web server's capabilities. Resolving Cross-Origin Resource Sharing (CORS) When managing multiple domains or during development with separate frontend and backend environments, cross-domain issues often arise. Nginx can efficie ...

Project Overview This guide demonstrates how to deploy a Python web service using Docker with Nginx for load balencing. The example includes MySQL and Redis dependencies, along with instructions for disabling load balancing if not needed. Project Structure 1. Dockerfile # Base image for the application FROM python:3.7 # Set working directory i ...

Overview Keepalived is a free, open-source routing software written in C that provides load balancing and high-availability capabilities. It operates at layers 3, 4, and 7 of the OSI model, functioning similarly to layer 3/4/7 switches. The software primarily offers two key features: load balancing (implemented through Linux's IP Virtual Server ...

OpenResty Versions and Variants Several Nginx-based web server implementations are available: OpenResty: An enhanced distribution of Nginx with LuaJIT integration (recommended) Nginx Plus: Commercial version with additional enterprise features Tengine: A fork of Nginx developed by Alibaba Installing OpenResty on Linux This guide uses CentOS 7 ...

Nginx serves dual purposes in modern infrastructure: it functions as both a web server and a load balancing solution through reverse proxy capabilities. This article explores how to implemant load balancing effectively using Nginx. Core Functions of Load Balancers A load balancer acts as an intermediary layer between clients and backend servers ...

Keepalived Overview Keepalived is an open-source software initially designed for managing LVS clusters, providing health monitoring for service nodes. It latter incorporated VRRP functionality to enable high availability solutions for various services like Nginx, HAProxy, and MySQL. Core Functionality LVS load balancer management Health monito ...

Dubbo's extension point loading system improves upon Java's standard SPI (Service Provider Interface) by addressing several limitations: Java SPI instanitates all implementations at once, potentially wasting resources on unused extensions Java SPI doesn't properly handle extension loading failures, making troubleshooting difficult Dubbo adds s ...

Understanding Proxy Services A proxy acts as an intermediary between clients and servers. In networking, proxies are commonly used to forward requests while providing control, security, or performance benefits. There are two primary types of proxies: - Forward Proxy: Serves client-side needs. For example, when a client within a restricted netwo ...

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 ...

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 ...
