----------------------------------------------------
Deployment Information:
- Email: $EMAIL
- Branch: $DEPLOYMENT_BRANCH
- Deployed: $(date)
- Deployment Duration: $(($(date +%s) - $DEPLOYMENT_START_TIME)) seconds
Service Status:
- PatchMon Service: $(systemctl is-active $SERVICE_NAME)
- Nginx Service: $(systemctl is-active nginx)
- PostgreSQL Service: $(systemctl is-active postgresql)
- SSL Certificate: $(if [ "$USE_LETSENCRYPT" = "true" ]; then echo "Enabled"; else echo "Disabled"; fi)
Diagnostic Commands:
- Service Status: systemctl status $SERVICE_NAME
- Service Logs: journalctl -u $SERVICE_NAME -f
- Nginx Status: systemctl status nginx
- Nginx Logs: journalctl -u nginx -f
- Database Status: systemctl status postgresql
- SSL Certificate: certbot certificates
- Disk Usage: df -h $APP_DIR
- Process Status: ps aux | grep $SERVICE_NAME
Troubleshooting:
- Check deployment log: cat $APP_DIR/patchmon-install.log
- Check service logs: journalctl -u $SERVICE_NAME --since "1 hour ago"
- Check nginx config: nginx -t
- Check database connection: sudo -u $DB_USER psql -d $DB_NAME -c "SELECT 1;"
- Check port binding: netstat -tlnp | grep $BACKEND_PORT

- SSL Enabled: $USE_LETSENCRYPT
- Service Name: $SERVICE_NAME
Directories:
- App Directory: $APP_DIR
- Backend: $APP_DIR/backend
- Frontend (built): $APP_DIR/frontend/dist
- Node.js isolation dir: $APP_DIR/.npm
Database Information:
- Name: $DB_NAME
- User: $DB_USER
- Password: $DB_PASS
- Host: localhost
- Port: 5432
Redis Information:
- Host: localhost
- Port: 6379
- User: $REDIS_USER
- Password: $REDIS_USER_PASSWORD
- Database: $REDIS_DB
Networking:
- Backend Port: $BACKEND_PORT
- Nginx Config: /etc/nginx/sites-available/$FQDN
Logs & Files:
- Deployment Log: $LOG_FILE
- Systemd Service: /etc/systemd/system/$SERVICE_NAME.service
Common Commands:
- Restart backend service: sudo systemctl restart $SERVICE_NAME
- Check backend status: systemctl status $SERVICE_NAME
- Tail backend logs: journalctl -u $SERVICE_NAME -f
- Test nginx config: nginx -t && systemctl reload nginx
- Check DB connection: sudo -u $DB_USER psql -d $DB_NAME -c "SELECT 1;"
First-Time Setup:
- Visit the web interface: $SERVER_PROTOCOL_SEL://$FQDN
- Create the admin account through the web UI (no pre-created credentials)
Notes:
- Default role permissions (admin/user) are created automatically on backend startup
- Keep this file for future reference of your environment
