Create RPM of Your Own Script in CentOS/Redhat

RPM ( RedHat Package Manager ) is a package management system for RHEL based systems. You may have seen that all the packages in rhel systems has extension .rpm. This tutorial will help you to how to create your own rpm file

I had created a script to take database backup, Today i have created a RPM file of that script, This is my first RPM created ever. Below are the steps which i follow to do it.

Step 1: Install Required Packages

First install the required packages to create rpm files.

# yum install rpm-build rpmdevtools

Step 2: Create Directory Structure

Go to users home directory, and create required directory structure using below command.

$ rpmdev-setuptree

Above command will create a directory structure like below .

$ tree rpm
rpm
|-- BUILD
|-- RPMS
|-- SOURCES
|-- SPECS
`-- SRPMS

In case `rpmdev-setuptree` command failed to create structure , you can manually create it

$ mkdir -p ~/rpm/{BUILD,RPMS,SOURCES,SPECS,SRPMS,tmp}

Step 3: Create rpmmacro File

Create ~/.rpmmacros file, with the following contents. Change the values of red highlighted names

%packager YOUR_NAME
%_topdir /home/YOUR_HOME_DIR/rpm
%_tmppath /home/YOUR_HOME_DIR/rpm/tmp

Step 4: Put Files in SOURCES Dir

Copy all your files and scripts folder inside ~/rpm/SOURCES folder, which we need to add in rpm file.

:~/rpm/SOURCES $  tree dbbackup-1
dbbackup-1
`-- backup.sh

Create a tarball of your code.

:~/rpm/SOURCES $ tar czf dbbackup-1.0.tar.gz dbbackup-1/

Step 5: Create SPEC File

Create a spec file ~/rpm/SPECS/dbbackup.spec using below content.

Name: dbbackup
Version: 1
Release: 0
Summary: Database backup rpm
Source0: dbbackup-1.0.tar.gz
License: GPL
Group: Rahul
BuildArch: noarch
BuildRoot: %{_tmppath}/%{name}-buildroot
%description
Write some descripton about your package.
%prep
%setup -q
%build
%install
install -m 0755 -d $RPM_BUILD_ROOT/etc/dbbackup
install -m 0755 backup.sh $RPM_BUILD_ROOT/etc/dbbackup/backup.sh
%clean
rm -rf $RPM_BUILD_ROOT
%post
echo . .
echo .Wring some descripton here to show after package installation!.
%files
%dir /etc/dbbackup
/etc/dbbackup/backup.sh

Change package name, script path, archive name , description etc, as per your requirement.

Step 6: Build RPM

After completing above steps, lets build your rpm by executing following command.

~ $ cd ~/rpm
~/rpm $ rpmbuild -ba SPECS/dbbackup.spec

After successful built, a rpm file will created like ~/rpm/RPMS/noarch/dbbackup-1-0.noarch.rpm

Install your rpm using ‘rpm -ivh dbbackup-1-0.noarch.rpm‘ and check if all files are properly installed.
