Saya sudah mencoba banyak tutorial web untuk mengaktifkan statistik HAProxy (hanya statistik haproxy google dan mencoba 10 tautan teratas) tetapi saya yakin ini adalah untuk versi HAProxy yang lebih lama. Saya menjalankan 1,7 pada Ubuntu 16.04 LTS.
Ini file /etc/haproxy/haproxy.cfg saya (ini termasuk instruksi yang diberikan oleh Datadog tentang mengaktifkan statistik).
Jika saya menghapus blok Listen ...., itu dimulai dengan baik. Saat itu ada saya mendapatkan kesalahan berikut:
sudo service haproxy stop
sudo service haproxy start
Job for haproxy.service failed because the control process exited with error code. See "systemctl status haproxy.service" and "journalctl -xe" for details.
Baik output journalctl dan systemctl menunjukkan "Layanan memulai terlalu cepat kesalahan

Ada ide?
