Getting started with creating an RPM package

Directory:

Specify the new workspace _ topdir
Create a working directory in the Workspace
Create a SPEC File
Create source file
Compile the RPM package

Install and uninstall the generated RPM package
Important Fields in the SPEC File

Specify a new Workspace _topdir

The default workspace is/usr/src/RedHatThrough the configuration filerpmmacrosSpecify:

cat>>~/.rpmmacros<<end > %_topdir /root/helloworld > end

This configuration can also be usedCommand LineTo specify:

rpmbuild --define "_topdir /root/helloworld" 

Create a working directory in the Workspace

mkdir -p /root/helloworld/{RPMS,SRPMS,BUILD,SOURCES,SPECS}
Working directory explanation:

1. Helloworld/BUILD: the command rpmbuild will decompress the source file in this directory and compile the program in this directory.
2. Helloworld/SPECS: stores spec file spec files
3. Helloworld/SOURCES: stores source files
4. Helloworld/SRPMS: stores rpm files containing source code
5. Helloworld/RPMS: stores rpm package files containing binary data

Create a SPEC File

helloworld/SPECS/hello.spec:

Summary: hello world rpm package Name: hello Version: 0.1 Release: 1 Source: %{name}-%{version}.tar.gz License: GPL Packager: amoblin Group: Application/System BuildRoot: %{_topdir}/root/ %description This is a software for making your life more beautiful! %prep rm -rf $RPM_BUILD_DIR/%{name}-%{version} zcat $RPM_SOURCE_DIR/%{name}-%{version}.tar.gz | tar -xv %build cd %{name}-%{version} gcc -o hello hello.c %install rm -rf %{buildroot} mkdir -p %{buildroot}/usr/local/bin/ cd %{name}-%{version} cp hello %{buildroot}/usr/local/bin/hello %files /usr/local/bin/hello

Create source file

hello.c:

#include <stdio.h> int main() { printf("Hello, World!\n"); return 0; }

Package the source filesSOURCESDirectory

mkdir -p hello-0.1 mv hello.c hello-0.1 tar czvf hello-0.1.tar.gz hello-0.1 mv hello-0.1.tar.gz /root/helloworld/SOURCES/

Compile the RPM package

# Compile rpm rpmbuild-vv-ba helloworld/SPECS/hello. spec # or use the command line to specify topdir to compile rpmbuild -- define "_ topdir/root/helloworld"-vv-ba helloworld/SPECS/hello. spec # verify SPEC rpmbuild -- define "_ topdir/root/helloworld"-vv-bl helloworld/SPECS/hello. spec

View the generated RPM package class capacity:

[root@localhost ~]# rpm -qpil helloworld/RPMS/i386/hello-0.1-1.i386.rpm

Install and uninstall the generated RPM package

[root@localhost ~]# rpm -iv helloworld/RPMS/i386/hello-0.1-1.i386.rpm Preparing packages for installation... hello-0.1-1 [root@localhost ~]# hello Hello, World! [root@localhost ~]# rpm -ev hello-0.1-1

Important Fields in the SPEC file:

1. Group: you must first define [less /usr/share/doc/rpm-*/GROUPS]
2. BuildRoot: installation phaseinstallIn%buildAfter the stage). The default root directory is%{_topdir}/BUILDROOT/
3. % Prep:prepareShell script called during preparation
4. % Build:buildShell scripts called during compilation
5. % Install:installShell script called during installation
   Note: Run% Prep,% Build,% InstallShell scriptpwdDirectory:/root/helloworld/BUILD
6. % Files: Specify which files are included in the generated binary RPM package. These files must beBuildRootDirectory exists
