Запуск/остановка/перезапуск кластера

Материал из Документация Ключ-АСТРОМ

Программное обеспечение Ключ-АСТРОМ Managed состоит из ряда служб Ключ-АСТРОМ, которые зависят друг от друга и должны быть остановлены или запущены в определенном порядке. Вы можете использовать официальный сценарий dynatrace.sh с дополнительными параметрами для правильного запуска, остановки или перезапуска служб Ключ-АСТРОМ. По умолчанию сценарий находится в /opt/dynatrace-managed/launcher/. Убедитесь, что у сценария dynatrace.sh есть разрешения на выполнение.

Вы можете выполнить сценарий dynatrace.sh с параметром (start, stop, restart, status, check, pid), как описано ниже.

  • start

Запускает все необходимые службы Ключ-АСТРОМ Managed в рекомендованном порядке.

[root@localhost]# ./dynatrace.sh start

  • stop

Останавливает все необходимые службы Ключ-АСТРОМ Managed в рекомендованном порядке.

[root@localhost]# ./dynatrace.sh stop

  • restart

Перезапускает все необходимые службы Ключ-АСТРОМ Managed в рекомендованном порядке.

[root@localhost]# ./dynatrace.sh restart

  • status

Отображает список необходимых служб Ключ-АСТРОМ и состояние каждой из них, включая подробную информацию о каждой службе:

[root@localhost]# ./dynatrace.sh status
