Project Summary: Resolving Magento 2.4 Environment Issues and Plesk-Related Conflicts
Live Server 1. Current Status: - The live version of Magento 2.4 works without any issues.
2. Problematic Behavior: - Developer instances using the exact same codebase display Error 500/503 since this morning. - Potential Cause: A recent Plesk update is suspected of causing these issues, as this has been a recurring problem after updates.
3. Cross-Domain Interference: - An unrelated domain on the same server, with a completely different codebase, also stops working unexpectedly. - Running a custom script to fix ownership and privileges in the vhost directory resolves some symptoms but does not fully address the root cause.
4. Configuration Discrepancies: - A comprehensive comparison (diff) of configuration files on the live server reveals discrepancies in Nginx/Apache, PHP-FPM, and SSL/TLS configurations, which may be contributing to the issue.
Development Server 1. Current Status: - Development instances running on different servers fail to work with the same Magento 2.4 codebase that functions perfectly on the live server.
2. Problematic Behavior: - Despite adjustments in permissions, ownership, and service restarts, the development server continues to show Error 500/503.
3. Configuration Differences: - Configuration files on the development server are inherently different due to its purpose, but they seem to be misaligned with the live server setup.
Objective 1. Diagnose and resolve the 500/503 errors affecting the developer instances. 2. Ensure the developer instances replicate the live server environment as closely as possible while maintaining their independent configurations. 3. Fix any Plesk 18-related issues causing conflicts or cross-domain interference.
Deliverables 1. Fully functioning developer instances of Magento 2.4 that mirror the live environment. 2. Isolation of domains on the same server to prevent cross-domain interference. 3. Comprehensive documentation of the solution, highlighting: - Configuration changes. - Any Plesk-related fixes. - Steps to prevent recurrence after future Plesk updates.
