Служба KeepAlived работает, но не выполняет скрипт проверки haproxy

Я настроил балансировщик нагрузки при отказе, чтобы он действовал как резервный, когда мой основной сервер выходит из строя. Поэтому я настроил Keepalived, который переключает плавающий виртуальный IP-адрес на другую машину всякий раз, когда не может найти службу HAProxy, работающую на другой машине. IP-адреса, указанные в файле conf, присутствуют на моем интерфейсе eth1.

На моем первичный балансировщик нагрузки я получаю

Вывод pidof pidof haproxy

Начальный

root@ubuntu-s-1vcpu-1gb-blr1-01:~# pidof haproxy
726 719

Среднее

root@ubuntu-s-2vcpu-4gb-blr1-01:~# pidof haproxy

Примечание : Я запустил сценарий /etc/keepalived/master.sh вручную, и он успешно работал.

РЕДАКТИРОВАТЬ1: Он не работает, даже когда я использую pidof -s haproxy

Переустановка пакета KeepAlived решила мою проблему.

Чтобы удалить поддержку активности:

sudo apt-get remove -y keepalived
sudo apt-get remove --auto-remove -y keepalived

Установка KEEPALIVED

sudo apt-get update
sudo apt-get install -y keepalived
