Package Bash/Perl script in Rpm Format:

Recently  I was working for one of the Script development. The automation package supposed to delivered on rhel6.
In process of roll out, I thought of using yum, It would be easy to install.
In this blog we will be creating a sample script and package it RPM format.

#!/bin/bash
date
ls

Note: Save the script named as test.sh
Below are the steps I followed.

• Install rpmbuild package, so we can get rpm build command.
   yum install rpmbuild
• Create a directory structure, We need a directory structure for rpm buildmkdir /root/rpmbuild
  mkdir -p /root/rpmbuild/{RPMS,SRPMS,SPEC,SOURCE,BUILD,tmp}
• Create a folder in SOURCEcd /root/rpmbuild/SOURCE
  mkdir test ; cp /root/test.sh /root/rpmbuild/SOURCE/test/
• Create a tar folder :tar -czvf  test.tar.gz test
• create a SPEC file in SPEC folder
  test.spec [Content of spec file]
  Name:test-1
  Version:1
  Release:1
  Summary: This is rpm development
  BuildArch:noarch
  Group:Dev
  License:GPL
  URL:http://localhost
  Source0:test.tar.gz
  Buildroot:%{_tmppath}/%{Name}-%{Version}-%{Release}-root-%{%{__id_u} -n}

  This is rpm development
  %prep
  %setup -q
  %install
  mkdir -p “$RPM_BUILD_ROOT/opt/test”
  cp -R * “$RPM_BUILD_ROOT/opt/test”
  %files
  /opt/test
  %clean
  rm -rf $RPM_BUILD_ROOt
  %post
  chmod 775 /opt/test*Save the spec file in /root/rpmbuild/SPEC folder
• Now we will build the rpm
  rpmbuild -v -bb /root/rpmbuild/SPEC/test.spec
  /* rpm will build and saved in /root/rpmbuild/RPMS/noarch folder
• Now we can install rpm using command
  rpm -ivh test.rpm
  %files in spec file specified installation location.After that we can check the test.sh file  /opt/test folder
