Supervisor Process Management

Codante uses Supervisor to manage Laravel Octane and queue workers.

Check Supervisor Status

# Status of all programs
ssh robertotcestari@216.238.103.47 "sudo supervisorctl status"

# Status of Octane specifically
ssh robertotcestari@216.238.103.47 "sudo supervisorctl status codante-octane"

# Status of queue workers (if configured)
ssh robertotcestari@216.238.103.47 "sudo supervisorctl status codante-worker"

# Check recent releases
ssh robertotcestari@216.238.103.47 "ls -la /var/www/codante-io-api/releases/ | tail -5"

Deploy New Release

When deploying via GitHub Actions + Deployer:

1. Merge to main branch
2. GitHub Actions triggers automated deployment
3. Deployer handles:
   • Code checkout to new release directory
   • Dependency installation
   • Cache clearing
   • Database migrations
   • Asset compilation
   • Service restarts (PHP-FPM, nginx, Supervisor)

Check deployment status:

ssh robertotcestari@216.238.103.47 "ls -la /var/www/codante-io-api/releases/ | tail -5"

Health Check

# Quick API health check
ssh robertotcestari@216.238.103.47 "curl -s http://127.0.0.1/health"

# Detailed status
ssh robertotcestari@216.238.103.47 "curl -s http://127.0.0.1/api/status | head -20"

# Check if PHP-FPM is responding
ssh robertotcestari@216.238.103.47 "curl -s -o /dev/null -w '%{http_code}' http://127.0.0.1/"

Security Considerations

1. SSH Keys: Ensure your SSH key is added to ~/.ssh/authorized_keys on the server
2. sudo Access: Use sudo for privileged commands (requires password or sudo setup)
3. Environment Variables: Never expose sensitive data in logs or console output
4. Log Files: Check logs for errors, security warnings, and performance issues
5. Backups: Always ensure backups exist before making changes to production
6. Worker Cache: Be aware that Supervisor-managed workers may cache code; restart after major changes
7. Log Retention: Security logs kept for 14 days; archive important logs locally
8. Shared Config: .env and other shared config in /var/www/codante-io-api/shared/ - changes survive deployments
9. Queue Jobs: Failed jobs are retained; monitor and clean up periodically

Troubleshooting

Connection Issues

If you can't connect:

1. Verify SSH key is configured: ssh-keyscan 216.238.103.47
2. Check your SSH config: ~/.ssh/config
3. Test connectivity: ping 216.238.103.47

Permission Denied

If you get "Permission denied":

1. Verify the username is robertotcestari
2. Check SSH key permissions: chmod 600 ~/.ssh/id_rsa
3. Ensure public key is on server: cat ~/.ssh/id_rsa.pub

Service Issues

If services are not running:

1. Check service status: sudo systemctl status SERVICE_NAME
2. View service logs: sudo journalctl -u SERVICE_NAME -n 50
3. Restart service: sudo systemctl restart SERVICE_NAME

Octane Not Responding

If Octane isn't responding:

1. Check if Octane is running: sudo supervisorctl status codante-octane
2. View recent logs: tail -f /var/log/supervisor/codante-octane.log
3. Restart Octane: sudo supervisorctl restart codante-octane
4. Check if bound to port 8089: sudo netstat -tlnp | grep 8089 or sudo ss -tlnp | grep 8089
5. Check Octane service via journalctl: journalctl -u supervisor -n 100 | grep octane

Supervisor Worker Issues

If queue workers are not processing:

1. Check supervisor status: sudo supervisorctl status
2. View worker logs: tail -f /var/log/supervisor/codante-worker.log
3. Restart workers: sudo supervisorctl restart codante-worker
4. Check for failed jobs: cd /var/www/codante-io-api/current && php artisan queue:failed

High Memory Usage

If Octane is consuming too much memory:

1. Check current memory usage: free -h
2. Check Octane memory: ps aux | grep octane | awk '{print $2, $4, $6, $11}'
3. Current config should trigger garbage collection at 50MB
4. Restart Octane: sudo supervisorctl restart codante-octane
5. Monitor with: watch -n 1 'ps aux | grep octane'
6. Review logs for memory leak patterns in /var/log/supervisor/codante-octane.log

Queue Job Issues

If queue jobs are failing or not processing:

1. Check queue status: cd /var/www/codante-io-api/current && php artisan queue:failed
2. View worker logs: tail -f /var/log/supervisor/codante-worker.log
3. Retry failed jobs: cd /var/www/codante-io-api/current && php artisan queue:retry all
4. Clear failed jobs: cd /var/www/codante-io-api/current && php artisan queue:clear
5. Monitor queue: cd /var/www/codante-io-api/current && php artisan queue:monitor redis:default

Log Files Growing Too Large

If log files are consuming too much disk space:

1. Check size: du -sh /var/www/codante-io-api/current/storage/logs/
2. Clear logs: cd /var/www/codante-io-api/current && php artisan log:clear
3. Archive old logs: gzip /var/www/codante-io-api/current/storage/logs/*.log.old
4. Download and remove: scp ... && ssh ... rm

nginx 502 Bad Gateway

If you see 502 errors in nginx:

1. Check if Octane is running: sudo supervisorctl status codante-octane
2. Check nginx error log: tail -f /var/log/nginx/error.log
3. Test Octane is bound to port 8089: curl http://127.0.0.1:8089
4. Restart Octane: sudo supervisorctl restart codante-octane
5. Check Octane logs: tail -f /var/log/supervisor/codante-octane.log

Payment Processing Issues

If Pagarme webhooks are failing:

1. Check payment logs: tail -f /var/www/codante-io-api/current/storage/logs/payments.log
2. Verify webhook configuration in .env
3. Check failed queue jobs: cd /var/www/codante-io-api/current && php artisan queue:failed
4. Retry webhook jobs: cd /var/www/codante-io-api/current && php artisan queue:retry all
