RPM Installation of WildFly 15 on CentOS 7

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
[harbottle-main]

gpgcheck=value

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."
