Linux

Install required tools

rpm -qa | grep rpmdevtools
yum list | grep rpmdevtools
yum install rpmdevtools

Create directory structure required for rpm build if not exist

rpmdev-setuptree

rpmbuild/
├── BUILD
├── RPMS
├── SOURCES
├── SPECS
└── SRPMS

Create source package under SOURCES

mkdir hello-0.0.1
cd hello-0.0.1

hello.sh

#!/bin/sh
echo "Hello world"
tar -cvzf hello-0.0.1.tar.gz hello-0.0.1

Create spec file and make necessary changes

cd ~/rpmbuild/SPECS
rpmdev-newspec hello.spec
Name:           hello
Version:        0.0.1
Release:        1%{?dist}
Summary:        A simple hello world script
BuildArch:      noarch

License:        GPL
Source0:        %{name}-%{version}.tar.gz

Requires:       bash

%description
A demo RPM build

%prep
%setup -q

%install
rm -rf $RPM_BUILD_ROOT
mkdir -p $RPM_BUILD_ROOT/opt/hello
cp * $RPM_BUILD_ROOT/opt/hello

%clean
rm -rf $RPM_BUILD_ROOT

%files
/opt/hello/*

%postun
rm -vrf /opt/hello

%changelog
* Sun Feb 04 2024 
- First version being packaged

Now directory structure should look like this

/home/tux/rpmbuild/
├── BUILD
├── BUILDROOT
├── RPMS
├── SOURCES
│   └── hello-0.0.1.tar.gz
├── SPECS
│   └── hello.spec
└── SRPMS

Build rpm using following command

rpmbuild -ba SPECS/hello.spec

where -b is build a is for both source and binary
if you want only binary then put -bb flag
if you want only source then put -bs flag

Install the rpm using following command

sudo rpm -ivh ~/rpmbuild/RPMS/noarch/hello-0.0.1-1.el8.noarch.rpm

Verify rpm installed successfully using following command

rpm -qi hello
tree /opt/hello

The %changelog entry of a package can be viewed, too:

rpm -q hello –changelog

Uninstall or erase installed rpm

sudo rpm -q | grep hello
sudo rpm -ve hello

Troubleshoot

To extract files and directories from rpm

rpm2cpio hello-0.0.1-1.el8.noarch.rpm | cpio -idmv

  1. Hey I know this is off topic but I was wondering if you knew of any widgets I could add to my blog that automatically tweet my newest twitter updates. I’ve been looking for a plug-in like this for quite some time and was hoping maybe you would have some experience with something like this. Please let me know if you run into anything. I truly enjoy reading your blog and I look forward to your new updates.

  5. Hey there would you mind sharing which blog platform you’re using? I’m going to start my own blog soon but I’m having a tough time making a decision between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your design and style seems different then most blogs and I’m looking for something unique. P.S Sorry for being off-topic but I had to ask!

  7. Привет всем! Сегодня затронем тему — выбор материала для крыши. Суть в том, что выбирать дешёвое — аукнется потом. Не хочешь рисковать — могу рекомендовать: установка мембранной кровли. На практике вижу: ПВХ покрытие — окупается за счёт долговечности. Допустим постоянные ремонты — а мембрана стоит 25-30 лет. Основные этапы: нанять опытную бригаду. Вот и соответственно: высокоэффективный инструмент для долговечной кровли.

  8. Приветствую! На первом этапе нужно разобраться — почему течёт у стен и парапетов. Дело в том, что: большинство проблем — некачественная обработка узлов. Ищешь тех кто умеет — могу рекомендовать: https://montazh-membrannoj-krovli-spb.ru. Зачем это: обход труб — всё сваривается. Допустим труба на крыше — обрамляется мембраной — опять же вода не пройдёт. Мы используем — фасонные детали из ПВХ. Что в итоге: удаётся достигать классных результатов — узлы надёжны.

  11. Hey! I know this is kinda off topic but I was wondering which blog platform are you using for this site? I’m getting sick and tired of WordPress because I’ve had problems with hackers and I’m looking at alternatives for another platform. I would be awesome if you could point me in the direction of a good platform.

  14. Aw, this was an exceptionally nice post. Taking a few minutes and actual effort to generate a superb article… but what can I say… I put things off a whole lot and don’t seem to get nearly anything done.
