Prerequisite
CentOS 7. I use minimal installation. I also need wget to download harbottle rpm repo (https://pkgs.org/download/wildfly), from which I will need to install WilfFly from. The harbottle repo is a Fedora Project repo. And Fedora is supported by Red Hat.
# yum install wget -y
Install HarBottle RPM Repo
# wget https://harbottle.gitlab.io/harbottle-main/7/x86_64/00703701-harbottle-main-release/harbottle-main-release-7-5.el7.noarch.rpm
# rpm -Uvh harbottle-main-release*rpm
Check the HarBottle RPM.
# rpm -ql harbottle-main-release
/etc/yum.repos.d/harbottle-main.repo
/usr/share/doc/harbottle-main-release-7
/usr/share/doc/harbottle-main-release-7/GPL
# rpm -q --scripts harbottle-main-release
# cat /etc/yum.repos.d/harbottle-main.repo

Use the gpgcheck option to specify if yum should perform a GPG signature check on packages. Replace value with:
0 — Disable GPG signature-checking on packages in all repositories, including local package installation.
1 (default) — Enable checking of GPG signature on all packages in all repositories, including local package installation. With gpgcheck enabled, all packages' signatures are checked."
repo_gpgcheck=0
Check rpm repo server certificate.
