This exercise was done on RHEL 6 and same steps are applicable for other variants too. This tutorial provides you with steps to create your own RPM packages in Linux. Following procedure shows creating a basic RPM package that includes a shell script. After the RPM is installed, the script is executed on the command prompt to display the output.

1. Creating RPM package in Linux

This exercise was done on RHEL 6 and same steps are applicable for other variants too. This tutorial provides you with
steps to create your own RPM packages in Linux. Following procedure shows creating a basic RPM package that
includes a shell script. After the RPM is installed, the script is executed on the command prompt to display the output.
Step 1 – Install necessary RPM dependencies
[student@desktop3 ~]$yum install rpm-build–y

Step 2 – Setup your package in a directory
[student@desktop3 ~]$mkdir myrpm-1.0
[student@desktop3 ~]$cd myrpm-1.0

(Create a simple script which executes after installing the rpm)
[student@desktop3 ~]$ vi myrpm.sh
#!/bin/bash
#
echo 'Hello There ! This is my RPM script...'
exit 0

(Make the script executable)
[student@desktop3 ~]$ chmod a+x myrpm.sh

Step 3 – Create a tar file of your package
[student@desktop3 ~]$ mkdir -p ~/rpmbuild/SOURCES
[student@desktop3 ~]$ mkdir -p ~/rpmbuild/SPECS
[student@desktop3 ~]$ tar -zcvf ~/rpmbuild/SOURCES/myrpm-1.0-1.tar.gz myrpm-1.0/
Step 4 – Create and edit SPEC file
[student@desktop3 ~]$ vi ~/rpmbuild/SPECS/myrpm.spec
Name: myrpm
Version: 1.0
Release: 1
Summary: MyRPM

Group: RHCE
License: GPL
URL: http://www.redhat.com
Source0: %{name}-%{version}-%{release}.tar.gz
BuildRoot: /var/tmp/%{name}-buildroot

%description
Installs /root/bin/myrpm.sh

%prep
%setup -q -n %{name}-%{version}

2. %build

%install
rm -rf $RPM_BUILD_ROOT
mkdir -p $RPM_BUILD_ROOT/root/bin
install -m 755 myrpm.sh $RPM_BUILD_ROOT/root/bin/myrpm.sh

%clean
rm -rf $RPM_BUILD_ROOT

%files
%defattr(-,root,root,-)
/root/bin/myrpm.sh

%changelog

Step 5 – Execute rpmbuild to build the RPM package
[student@desktop3 ~]$rpmbuild -ba rpmbuild/SPECS/myrpm.spec

Step 6 – Install and Run the RPM package
[root@desktop3 ~]# rpm -ivh /home/student/rpmbuild/RPMS/x86_64/myrpm-1.0-1.x86_64.rpm

[root@desktop3 ~]# myrpm.sh
Hello There ! This is my RPM script...
