В производственной среде вам потребуется много компонентов, установленных на вашем сервере, чтобы гарантировать, что ваши приложения работают правильно. К сожалению, выполнение команды установки некоторого компонента, когда компонент уже установлен, может привести к неправильной настройке компонента, поэтому ваше приложение может работать не так, как ожидалось.
Самое простое решение — узнать, какие пакеты установлены в системе, перед установкой или даже обновлением. Это можно просто сделать в Ubuntu 16.04 с помощью следующей команды:
apt list --installedЭто сгенерирует подробный вывод со списком установленных пакетов на терминале:
