Preface

Rpm is the abbreviation of red hat package manager, similar to msi installation package under windows.

The main purpose of rpm repackaging is as follows:

  • Installation package is not fully fit for purpose
  • Quickly generate installation package from the results of source compilation

1. Tools required

The main tools required are as follows:

  • RPM build (packaging)
  • rpmrebuild (unpacking)

Installation:

sudo yum install rpm-build rpmrebuild

2. unpack

The following is described in redis-5.0.5-1.fc27.x86_.rpm.

2.1 create packing directory

rpmrebuild -p redis-5.0.5-1.fc27.x86_64.rpm

The directory ~ / rpmbuild will be added after execution

2.2 extraction of SPEC documents

rpmrebuild -s redis.spec -p redis-5.0.5-1.fc27.x86_64.rpm

Put the redis.spec file in the ~ / rpmbuild/SPECS directory

cp redis.spec ~/rpmbuild/SPECS

2.3 extract rpm file

  • Create build folder

To view redis.spec:

BuildArch:     x86_64
Name:          redis
Version:       5.0.5
Release:       1.fc27

Create the folder Name-Version-Release.BuildArch in ~ / rpmbuild/BUILDROOT /, i.e. redis-5.0.5-1.fc27.x86_

mkdir ~/rpmbuild/BUILDROOT/redis-5.0.5-1.fc27.x86_64
  • Extract all files of rpm
rpm2cpio redis-5.0.5-1.fc27.x86_64.rpm | cpio -div
  • rpm extract file copy to create folder

Copy the extracted file to ~ / rpmbuild / buildroot / redis-5.0.5-1.fc27.x86_directory

File structure:

$ tree

3. Customize and modify spec file

The main contents of redis.spec are as follows:

# rpmrebuild autogenerated specfile

%define defaultbuildroot /
AutoProv: no
%undefine __find_provides
AutoReq: no
%undefine __find_requires
# Do not try autogenerate prereq/conflicts/obsoletes and check files
%undefine __check_files
%undefine __find_prereq
%undefine __find_conflicts
%undefine __find_obsoletes
# Be sure buildpolicy set to do nothing
%define __spec_install_post %{nil}
# Something that need for rpm-4.1
%define _missing_doc_files_terminate_build 0

Mainly need to be modified

  • Requires
  • %files
  • Script (pre install script% pre install script% post pre uninstall script% preun post uninstall script% post)

4. pack

rpmbuild common parameters:

  • -bb compile only binary rpm packages
  • -bs only compiles source rpm package
  • -ba compiles both binary and source rpm packages
cd ~/rpmbuild/SPECS

rpmbuild -ba redis.spec

install

sudo rpm -ivh redis-5.0.5-1.fc27.x86_64.rpm

5. other

5.1 conversion of RPM and deb

Install alien

perl Makefile.PL
make
sudo make instal

rpm to deb

# alien redis-server-5.0.7-2.x86_64.rpm 
redis-server_5.0.7-3_amd64.deb generated

install

dpkg -i redis-server_5.0.7-3_amd64.deb

deb to rpm

Warning: Skipping conversion of scripts in package redis-server: postinst postrm preinst prerm
Warning: Use the --scripts parameter to include the scripts.
redis-server-5.0.7-2.x86_64.rpm generated
