Standard Logging Directory - Complete:
✅ LOG DIRECTORY STRUCTURE FIXED: Changed from symlinked /var/lib/aitbc/logs to standard /var/log/aitbc
- setup.sh: Updated to create /var/log/aitbc as actual logs directory
- systemd services: Updated all services to use /var/log/aitbc
- Removed symlink: No longer creating symlink from /var/lib/aitbc/logs to /var/log/aitbc
- Reason: /var/log/aitbc is standard Linux location for logs
✅ BEFORE vs AFTER:
❌ Before (Non-standard):
/var/lib/aitbc/logs/ (created directory)
/var/log/aitbc -> /var/lib/aitbc/logs/ (symlink)
systemd ReadWritePaths=/var/lib/aitbc/logs
Non-standard logging location
✅ After (Standard Linux):
/var/log/aitbc/ (actual logs directory)
No symlink needed
systemd ReadWritePaths=/var/log/aitbc
Standard Linux logging location
✅ SETUP SCRIPT CHANGES:
📁 Directories: Create /var/log/aitbc instead of /var/lib/aitbc/logs
📋 Permissions: Set permissions on /var/log/aitbc
👥 Ownership: Set ownership on /var/log/aitbc
📝 README: Create README in /var/log/aitbc
🔗 Symlink: Removed symlink creation
✅ SYSTEMD SERVICES UPDATED:
🔧 aitbc-advanced-ai.service: ReadWritePaths=/var/log/aitbc /var/lib/aitbc/data
🔧 aitbc-enterprise-api.service: ReadWritePaths=/var/log/aitbc /var/lib/aitbc/data
🔧 aitbc-multimodal-gpu.service: ReadWritePaths=/var/log/aitbc /var/lib/aitbc/data /dev/nvidia*
🔧 aitbc-web-ui.service: ReadWritePaths=/var/log/aitbc /var/lib/aitbc/data
✅ STANDARD LINUX COMPLIANCE:
📁 /var/log/aitbc: Standard location for application logs
📁 /var/lib/aitbc/data: Standard location for application data
📁 /var/lib/aitbc/keystore: Standard location for secure storage
📁 /etc/aitbc: Standard location for configuration
🎯 FHS Compliance: Follows Linux Filesystem Hierarchy Standard
✅ BENEFITS:
✅ Standard Practice: Uses conventional Linux logging location
✅ Tool Compatibility: Works with standard log management tools
✅ System Integration: Integrates with system logging infrastructure
✅ Monitoring: Compatible with logrotate and monitoring tools
✅ Documentation: Clear and standard directory structure
✅ CODEBASE CONSISTENCY:
📋 Documentation: Already references /var/log/aitbc in many places
🔧 Services: All systemd services now use consistent log path
📝 Scripts: Log scripts and tools work with standard location
🎯 Standards: Follows Linux conventions for logging
RESULT: Successfully updated entire codebase to use standard /var/log/aitbc directory for logs, eliminating non-standard symlinked structure and ensuring Linux FHS compliance.
## 🚀 Central Virtual Environment Implementation
- Created central venv at /opt/aitbc/venv for all services
- Updated 34+ systemd services to use central python interpreter
- Fixed PYTHONPATH configurations for proper module imports
- Created aitbc-env wrapper script for environment management
## 📦 Requirements Management Overhaul
- Consolidated 8 separate requirements.txt files into central requirements.txt
- Added web3>=6.11.0 for blockchain functionality
- Created automated requirements migrator tool (scripts/requirements_migrator.py)
- Established modular requirements structure (requirements-modules/)
- Generated comprehensive migration reports and documentation
## 🔧 Service Configuration Fixes
- Fixed Adaptive Learning service domain imports (AgentStatus)
- Resolved logging conflicts in zk_proofs and adaptive_learning_health
- Created missing data modules (consumer_gpu_profiles.py)
- Updated CLI to version 0.2.2 with proper import handling
- Fixed infinite loop in CLI alias configuration
## 📡 Port Mapping and Service Updates
- Updated blockchain node port from 8545 to 8005
- Added Adaptive Learning service on port 8010
- Consolidated P2P/sync into blockchain-node service
- All 5 core services now operational and responding
## 📚 Documentation Enhancements
- Updated SYSTEMD_SERVICES.md for Debian root usage (no sudo)
- Added comprehensive VIRTUAL_ENVIRONMENT.md guide
- Created REQUIREMENTS_MERGE_SUMMARY.md with migration details
- Updated RUNTIME_DIRECTORIES.md for standard Linux paths
- Fixed service port mappings and dependencies
## 🛠️ CLI Improvements
- Fixed import errors and version display (0.2.2)
- Resolved infinite loop in bashrc alias
- Added proper error handling for missing command modules
- Created aitbc-cli wrapper for clean execution
## ✅ Operational Status
- 5/5 AITBC services running successfully
- All health checks passing
- Central virtual environment fully functional
- Requirements management streamlined
- Documentation accurate and up-to-date
## 🎯 Technical Achievements
- Eliminated 7 redundant requirements.txt files
- Reduced service startup failures from 34+ to 0
- Established modular dependency management
- Created reusable migration tooling
- Standardized Debian root deployment practices
This represents a complete infrastructure modernization with improved reliability,
maintainability, and operational efficiency.
- Change file mode from 644 to 755 for all project files
- Add chain_id parameter to get_balance RPC endpoint with default "ait-devnet"
- Rename Miner.extra_meta_data to extra_metadata for consistency
