# SystemD Services Management Guide
|
||
|
||
**Last Updated**: 2026-03-29
|
||

||
systemctl list-units --all | grep aitbc
|
||
|
||
# Check service status
|
||
systemctl status aitbc-coordinator-api.service
|
||
|
||
# Start a service
|
||
systemctl start aitbc-coordinator-api.service
|
||
|
||
# Stop a service
|
||
systemctl stop aitbc-coordinator-api.service
|
||
|
||
# Restart a service
|
||
systemctl restart aitbc-coordinator-api.service
|
||

|
||
### Bulk Operations
|
||
```bash
|
||
# Start all core services

||
systemctl start aitbc-coordinator-api aitbc-blockchain-node aitbc-exchange-api aitbc-wallet
|
||
|
||
# Restart all agent services
|
||
systemctl restart aitbc-agent-* aitbc-ai-service
|
||
|
||
# Check all services status
|
||
systemctl status aitbc-*
|
||
```
|
||
|
||
## 📊 Service Monitoring
|
||
|
||
### Health Checks
|
||
```bash
|
||
# Real-time monitoring
|
||
watch -n 5 'systemctl status aitbc-* --no-pager'
|
||
|
||
# Service failures
|
||
journalctl -u aitbc-coordinator-api.service --since "1 hour ago" -p err
|
||
|
||
# All service logs
|
||
journalctl -f | grep aitbc
|
||
```
|
||
|
||
### Performance Monitoring
|
||
```bash
|
||
# Resource usage
|
||
systemctl status aitbc-* | grep -E "(CPU|Memory)"
|
||
|
||
# Service start times
|
||
systemctl show aitbc-coordinator-api.service --property=ActiveEnterTimestamp
|
||
|
||
# Dependency failures
|
||
systemctl list-dependencies aitbc-coordinator-api.service
|
||
```
|
||
|
||
## 🔍 Troubleshooting
|
||
|
||
### Common Issues
|
||
|
||
#### Service Not Starting
|
||
```bash
|
||
# Check recent logs
|
||
journalctl -u aitbc-service-name.service -n 20
|
||
|
||
# Check for missing files
|
||
systemctl cat aitbc-service-name.service | grep ExecStart
|
||
|
||
# Verify working directory
|
||
ls -la /path/to/working/directory
|
||
```
|
||
|
||
#### Python Module Errors
|
||
```bash
|
||
# Check PYTHONPATH
|
||
systemctl cat aitbc-service-name.service | grep PYTHONPATH
|
||
|
||
# Verify module exists
|
||
python3 -c "import module.name"
|
||
|
||
# Install missing dependencies
|
||
pip3 install missing-package
|
||
```
|
||
|
||
#### Permission Issues
|
||
```bash
|
||
# Check file permissions
|
||
ls -la /var/lib/aitbc/keystore/
|
||
|
||
# Fix keystore permissions
|
||
chmod 700 /var/lib/aitbc/keystore/
|
||
chown root:root /var/lib/aitbc/keystore/
|
||
```
|
||
|
||
### Service-Specific Fixes
|
||
|
||
#### Coordinator API
|
||
```bash
|
||
# Check environment files
|
||
ls -la /home/oib/aitbc/apps/coordinator-api/.env
|
||
|
||
# Verify Python path
|
||
python3 -c "import sys; print(sys.path)"
|
||
|
||
# Test manual startup
|
||
cd /home/oib/aitbc/apps/coordinator-api
|
||
PYTHONPATH=/home/oib/aitbc/apps/coordinator-api/src python3 -m uvicorn app.main:app --host 0.0.0.0 --port 8000
|
||
```
|
||
|
||
#### Blockchain Node
|
||
```bash
|
||
# Check data directory
|
||
ls -la /var/lib/aitbc/data/
|
||
|
||
# Verify configuration
|
||
cat /opt/aitbc/apps/blockchain-node/.env.production
|
||
|
||
# Test blockchain module
|
||
cd /opt/aitbc/apps/blockchain-node
