type httpListener struct {
	opts        TCPOptions
	listeners   []net.Listener    // underlying TCP listeners.
	acceptCh    chan acceptResult // channel where all TCP listeners write accepted connection.
	ctx         context.Context
	ctxCanceler context.CancelFunc
}

// start - starts separate goroutine for each TCP listener.  A valid new connection is passed to httpListener.acceptCh.

### Usage

```
minio server --config config.yaml
```

Lets you start MinIO server with all inputs to start MinIO server provided via this configuration file, once the configuration file is provided all other pre-existing values on disk for configuration are overridden by the new values set in this configuration file.

Following is an example YAML configuration structure.
```yaml

	sync.RWMutex
	pubsub   *pubsub.PubSub[log.Info, madmin.LogMask]
	console  *console.Target
	nodeName string
	logBuf   *ring.Ring
}

// NewConsoleLogger - creates new HTTPConsoleLoggerSys with all nodes subscribed to
// the console logging pub sub system
func NewConsoleLogger(ctx context.Context, w io.Writer) *HTTPConsoleLoggerSys {
	return &HTTPConsoleLoggerSys{
		pubsub:  pubsub.New[log.Info, madmin.LogMask](8),

			echo "server$i log:"
			cat "${WORK_DIR}/dist-minio-server$i.log"
		done
		pkill -9 minio
		echo "FAILED"
		purge "$WORK_DIR"
		exit 1
	fi
}

function main() {
	# use same ports for all tests
	start_port=$(shuf -i 10000-65000 -n 1)

	perform_test "2" ${start_port}
	perform_test "1" ${start_port}
	perform_test "3" ${start_port}
}

(__init__ "$@" && main "$@")
rv=$?

}

// Lookup - initializes LDAP config, overrides config, if any ENV values are set.

	kvs := s[config.IdentityLDAPSubSys][config.Default]
	if len(kvs) > 0 {
		for _, k := range removedKeys {
