Very useful. I am using it as part of a docker environment that will deploy PHP code via capistrano.

Works on CentOS 6 too. Thanks a lot.

Why can't you make an RPM for rbenv and put it on EPEL?

Thanks you very much

For some packages(example: libyaml-devel). You might need to enable epel and powertools repos for rhel8 based OS'es. Tested on rocky.

sudo dnf install epel-release
sudo dnf config-manager --set-enabled powertools

ruby-build has now:
git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build

FYI, for CentOS 9, powertools are called crb(CodeReady Linux Builder), so you need to run below command to enable powertools to install libyaml-devel

dnf config-manager --set-enabled crb
