kesalahan konfigurasi haproxy

Ini konfigurasi saya

global
        log /dev/log   local0
        log 127.0.0.1   local1 notice
        maxconn 4096
        user haproxy
        group haproxy
        daemon

defaults
        log     global
        mode    http
        option  httplog
        option  dontlognull
        retries 3
        option redispatch

        contimeout     5000
        clitimeout     50000
        srvtimeout     50000

    server apache 192.168.1.10:8001 weight 1  maxconn 512 check

Setelah konfigurasi saya me-restart layanan haproxy, yang saya dapatkan pesan berikut

Saya melakukan langkah-langkah di atas dalam wadah buruh pelabuhan. Bagaimana cara reslove ??

Terima kasih.

Sintaks telah berubah dalam Versi HAProxy baru-baru ini. Saya punya masalah di Versi 1.6.5:

Perubahan: listen webfarm 0.0.0.0:80

Untuk:

listen webfarm

bind 0.0.0.0:80
