Phase 3: Add interactive PHP Performance Optimizer (modules/performance/php-optimizer.sh)
COMPLETE INTERACTIVE MENU SYSTEM:
- 8 main menu options for comprehensive PHP optimization
- Domain selection with PHP version display
- Real-time analysis and recommendations
- Color-coded severity levels (CRITICAL/HIGH/MEDIUM/LOW)
- Safe implementation with cecho() helper
MENU OPTIONS:
1. Analyze Single Domain - Complete PHP analysis report
2. Analyze All Domains - Server-wide analysis with issue detection
3. Quick Health Check - Overall health score based on issues
4. Optimize Domain - Detect issues + show recommendations
5. Optimize Server-Wide - (Placeholder for future)
6. View OPcache Statistics - Hit rates, memory usage, cache efficiency
7. View PHP-FPM Process Stats - Memory usage, process counts, pool config
8. Check Configuration Issues - Grouped by severity with recommendations
FEATURES IMPLEMENTED:
- Domain selection with user/PHP version context
- Comprehensive analysis using lib/php-analyzer.sh
- Issue detection with 4 severity levels
- OPcache statistics with hit rate analysis
- PHP-FPM resource usage tracking
- Optimal max_children calculations
- Health scoring system (0-100)
- Color-coded output for readability
ANALYSIS CAPABILITIES:
- PHP version detection per domain
- Configuration hierarchy display (4 priority levels)
- Effective settings resolution
- PHP-FPM pool configuration parsing
- Resource usage statistics (processes, memory)
- OPcache performance metrics
- Traffic analysis (requests/min, peak concurrent)
- Error analysis (7-day history)
ISSUE DETECTION:
- Config mismatches (post_max_size < upload_max_filesize)
- Security risks (display_errors = On)
- Performance issues (low memory_limit, OPcache disabled)
- Capacity issues (max_children errors)
- Memory leaks (pm.max_requests = 0)
- Resource waste (pm=static on low traffic)
RECOMMENDATIONS ENGINE:
- Calculates optimal pm.max_children based on:
* System memory (total - reserved)
* Average memory per process
* 20% safety buffer
- OPcache optimization suggestions
- Memory limit adjustments
- Process manager mode recommendations
SAFETY FEATURES:
- Read-only analysis (no modifications yet)
- Root user check
- PHP-FPM detection with warnings
- Graceful handling of missing data
- Clear "not yet implemented" placeholders for future features
DISPLAY FEATURES:
- Formatted banners and section separators
- Color-coded severity (RED=critical, YELLOW=high, BLUE=medium, GREEN=low)
- Progress indicators for multi-domain analysis
- Summary statistics and health scores
- Grouped issue display by severity
INTEGRATION:
- Uses lib/php-detector.sh for detection (Phase 1)
- Uses lib/php-analyzer.sh for analysis (Phase 2)
- Uses lib/system-detect.sh for system detection
- Uses lib/user-manager.sh for user/domain management
NOT YET IMPLEMENTED (Future):
- Automatic configuration changes (backup/apply/restore)
- Server-wide optimization in single action
- Backup/restore functionality
- Integration with live-attack-monitor (NOT requested by user)
USAGE:
bash /root/server-toolkit/modules/performance/php-optimizer.sh
All 3 phases complete! PHP optimizer ready for testing and refinement.
