Elasticsearch is a distributed, RESTful search and analytics engine built on Apache Lucene. It stores data as JSON documents in indices and provides near-real-time full-text search, log aggregation, metrics analysis, and complex aggregation queries through a simple HTTP/JSON API. Elasticsearch is the core component of the Elastic Stack (ELK Stack) — Elasticsearch stores and searches […]
pgAdmin 4 is the official, full-featured web-based administration and development platform for PostgreSQL. It provides a graphical interface for managing databases, schemas, tables, views, functions, roles, and server connections; a SQL query editor with syntax highlighting and query execution plans; a visual schema designer; backup and restore wizards; and monitoring dashboards for server statistics. pgAdmin […]
phpMyAdmin is a web-based graphical administration interface for MySQL and MariaDB databases. It allows developers and DBAs to manage databases, tables, rows, users, and permissions through a browser without needing to use the command-line MySQL client. phpMyAdmin is especially useful for non-technical users who need to browse data, run queries, import/export CSV or SQL files, […]
Prometheus is a time-series metrics collection and alerting system widely used for monitoring cloud infrastructure and web servers. The nginx-prometheus-exporter (nginx-exporter) is a lightweight Go binary that reads Nginx’s built-in stub_status page and exposes the metrics in Prometheus format — active connections, total requests, connection states (reading, writing, waiting), and request rate. Combined with Grafana […]
A default Nginx installation serves content, but many security hardening steps are not enabled by default. Hardening Nginx means configuring HTTP security headers to prevent XSS, clickjacking, and MIME sniffing attacks; enforcing TLS 1.3 and strong cipher suites to eliminate outdated protocol vulnerabilities; enabling OCSP Stapling so clients can verify certificate validity without a round-trip […]
WebSockets provide full-duplex communication channels over a single TCP connection, enabling real-time features such as live chat, push notifications, collaborative editing, gaming, and live dashboards. Unlike standard HTTP, which is request-response, WebSocket connections are persistent and bidirectional — the server can push data to clients at any time without a client request. Nginx can act […]
Even when free trusted certificates from Let’s Encrypt are available for public domains, self-signed certificates serve important roles: development environments, internal network services, IoT devices, automated testing pipelines, and machine-to-machine communication within a private network. Unlike Let’s Encrypt certificates, self-signed certificates require no domain ownership verification or outbound internet access — they can be generated […]
A LAMP stack — Linux, Apache HTTP Server, MySQL (or MariaDB), and PHP — is the original and most widely deployed open-source web hosting stack. It has powered millions of websites since the early 2000s and remains the default for hosting control panels (cPanel, Plesk, DirectAdmin) and many shared hosting environments. Apache’s .htaccess support, mod_rewrite, […]
A LEMP stack — Linux, Nginx, MySQL (or MariaDB), and PHP — is the standard modern web server stack for hosting PHP applications such as WordPress, Laravel, Drupal, and Magento. Compared to the traditional LAMP stack, Nginx handles concurrent requests more efficiently under high load due to its event-driven non-blocking architecture, making it the preferred […]
OpenLiteSpeed (OLS) is the open-source version of LiteSpeed Web Server — one of the highest-performance HTTP servers available, purpose-built for serving PHP applications. OpenLiteSpeed uses an event-driven architecture similar to Nginx but includes a built-in PHP engine (LSAPI) that processes PHP requests 3–5x faster than PHP-FPM behind Nginx, eliminating the socket overhead of the FastCGI […]
