How to get a list of packages installed in centos?

Question

CentOS

Good afternoon.
How can I get a list of packages installed in centos without taking into account the dependencies of these packages? (rpm -qa lists all packages installed on the system).
As, for example, it is done in gentoo in the world. Having this file and a couple more configs, you can deploy a copy of the working system with one command.

Answer 1

and why rpm -qa is not suitable??
rpm -qa > rpm.list
Install
yum install `cat rpm.list`

Answer 2

I managed to solve the problem in this way:
We get a list of installed packages without versions for the listed architectures.
Not an expert on regular expressions, don't kick too hard.
Ruslan Fedoseev suggested the correct option above
rpm -qa --qf "%{NAME}\n"
