How to set up a push server on BitrixVM?

Question

1C-Bitrix

For all the links that I find on this topic (for example , https://dev.1c-bitrix.ru/learning/course/index.php... ) it says that everything is configured in BitrixVM, installed and working out of the box.
I have Bitrix virtual appliance version 7.4.3 but nothing works.
However:

# systemctl status push-server
Unit push-server.service could not be found.

# yum list installed | grep push
# yum list installed | grep redis
Those. there is no push server. The packages are not even installed.
How is that? How to install?

Answer 1

In Bitrix, you need to install the push server explicitly according to this instruction: https://dev.1c-bitrix.ru/learning/course/index.php...
After that, it starts working by itself without settings.
