From fb300bb364b8ed14bd69586f44b87e252ee75546 Mon Sep 17 00:00:00 2001 From: cschantz Date: Thu, 11 Dec 2025 21:53:05 -0500 Subject: [PATCH] Add intelligent server-wide PHP optimization (option 5) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit NEW FEATURE: Optimize Server-Wide PHP Settings This implements the missing menu option 5 with intelligent, RAM-aware optimization that analyzes the ENTIRE server before making any changes. INTELLIGENT OPTIMIZATION PROCESS: Step 1: Server Memory Capacity Analysis - Calculates total RAM vs current max capacity across all pools - Shows status: HEALTHY, CAUTION, WARNING, or CRITICAL - Identifies if server is at risk of OOM Step 2: Balanced Memory Allocation - Uses calculate_balanced_memory_allocation() from php-analyzer.sh - Distributes available RAM proportionally based on traffic - Ensures total allocations never exceed physical RAM - Accounts for system overhead (reserves 2GB or 20% of RAM) Step 3: Smart Recommendations - Shows BEFORE/AFTER values for each user - Displays reason: REDUCE (prevent OOM), INCREASE (traffic demands), or OPTIMAL - Requires explicit "yes" confirmation before applying Step 4: Batch Optimization - Applies pm.max_children settings for all users - Tracks: OPcache disabled domains (manual intervention needed) - Shows real-time progress per domain - Automatic PHP-FPM reload after changes FEATURES: ✓ Prevents OOM: Never allocates more RAM than physically available ✓ Traffic-aware: High-traffic sites get more resources ✓ Safe defaults: Minimum 5, maximum 200 processes per pool ✓ Progress tracking: Shows optimization status for each domain ✓ Summary report: Total optimized, skipped, detected issues ✓ Automatic restart: Reloads PHP-FPM services after changes EXAMPLE OUTPUT: Analyzing server capacity... Total RAM: 16384MB Current max capacity: 14200MB (86%) Status: CAUTION - Approaching memory limits Calculating balanced optimization... user1: 50 → 35 (REDUCE - prevent OOM) user2: 20 → 45 (INCREASE - traffic demands) user3: 30 → 30 (OPTIMAL) Apply these balanced optimizations?
