This includes having a robust PHP installation with essential extensions, a web server (Nginx is recommended for its performance characteristics with Octane), and Composer. We’ll […]
Prerequisites and System Preparation This guide assumes a foundational understanding of Redis, Sentinel, and Linux system administration. We will be setting up a Redis Sentinel cluster on openSUSE Leap 15.5. Ensure you have at least three nodes available for the Sentinel cluster to achieve quorum and fault tolerance. For this demonstration, we’ll use three nodes, […]
Diagnosing Magento 2 Cron Job Deadlocks on RHEL 9 Magento 2 Enterprise deployments, particularly those leveraging the multi-process queue worker architecture, can encounter insidious deadlocks within cron job execution. These deadlocks often manifest as stalled cron processes, unprocessable queue messages, and a general degradation of system performance. This document details a systematic approach to diagnosing […]
Varnish 7 Configuration for Magento 2 Enterprise Achieving sub-100ms P99 response times for a high-traffic Magento 2 Enterprise deployment hinges on a meticulously tuned Varnish cache layer. This section details critical Varnish 7 configuration parameters and VCL snippets essential for optimizing Magento 2 performance, specifically when terminating SSL at Nginx and serving content from Varnish. […]
Pre-Upgrade System Health Check and Prerequisites Before embarking on the Magento 2.4.4 to 2.4.7 upgrade, a thorough assessment of the current environment is paramount.
