Build RPM package

To speed up some work processes with a single RPM package will bring more flexibility than deployment of single files/directories across different systems. Also a possibility to upgrade the installations without tracking of file versions over different systems.

This example will describe how to package a example script into a RPM package.

This could be also a full application or a file-set. In this case sync-brain.sh, script with sync logic.

Build process was set up on openSUSE 15.0.

mkdir -p ~/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
echo '%_topdir %(echo $HOME)/rpmbuild' > ~/.rpmmacros

Now in Folder SPECS create your project spec-file:

vim /root/rpmbuild/SPECS/sync-brain.spec

# spec file for package sync-brain
Name:           sync-brain
Version:        0.1

cp -r %{_sourcedir}/** %{_builddir}/opt/sync-brain
 
%install
install -m 0755 -d $RPM_BUILD_ROOT/opt/sync-brain

Start the build process with an rpm -b command:

rpmbuild -ba SPECS/project.spec

sync-brain.sh script, which should be packaged was placed in SOURCES directory. After a sucessfull build, RPM-Package will be found under RPMS.

Now try to install your RPM package:

rpm -Uvh RPMS/x86_64/sync-brain-0.1-2.x86_64.rpm

Possible stages:
%pre – This is where code is run before the install scripts run.
%preun – The section where code is executed prior to uninstall
%post – Section for code to be executed after installation
%postun – Section for code to be executed after uninstallation
