RPM (RedHat Package Manager) is a package management system for RHEL based systems. You may have seen that all the packages in Redhat based systems have extension .rpm. This tutorial will help you to how to create RPM for your own script
I had created a script to take database backup, Today I have created an 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 of all, you need to install the required packages on your system 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.
$ ls -l rpmbuild drwxr-xr-x 2 root root 6 Oct 25 03:09 BUILD drwxr-xr-x 2 root root 6 Oct 25 03:09 RPMS drwxr-xr-x 2 root root 6 Oct 25 03:09 SOURCES drwxr-xr-x 2 root root 6 Oct 25 03:09 SPECS drwxr-xr-x 2 root root 6 Oct 25 03:09 SRPMS
In case rpmdev-setuptree command failed to create structure, you can manually create it
$ mkdir -p ~/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS,tmp}
Step 3 – Create rpmmacro File
Now create ~/.rpmmacros file, with the following contents. Change the values of red highlighted names
~/.rpmmacros
%packagerYOUR_NAME %_topdir %(echo $HOME)/rpmbuild %_smp_mflags %( \ [ -z "$RPM_BUILD_NCPUS" ] \\\ && RPM_BUILD_NCPUS="`/usr/bin/nproc 2>/dev/null || \\\ /usr/bin/getconf _NPROCESSORS_ONLN`"; \\\ if [ "$RPM_BUILD_NCPUS" -gt 16 ]; then \\\ echo "-j16"; \\\ elif [ "$RPM_BUILD_NCPUS" -gt 3 ]; then \\\ echo "-j$RPM_BUILD_NCPUS"; \\\ else \\\ echo "-j3"; \\\ fi ) %__arch_install_post \ [ "%{buildarch}" = "noarch" ] || QA_CHECK_RPATHS=1 ; \ case "${QA_CHECK_RPATHS:-}" in [1yY]*) /usr/lib/rpm/check-rpaths ;; esac \ /usr/lib/rpm/check-buildroot
Step 4 – Copy Files under SOURCES Directory
Copy all your files and scripts folder inside ~/rpmbuild/SOURCES directory, which we need to add in rpm file. For this tutorial, I have used all the files created in our tutorial Advance Bash Script for MySQL.
$ cd ~/rpmbuild/SOURCES $ ls -l mydumpadmin-1 -rw-r--r-- 1 root root 125 Oct 25 03:54 credentials.txt -rw-r--r-- 1 root root 4693 Oct 25 03:54 mysql-dump.sh -rw-r--r-- 1 root root 1008 Oct 25 03:54 README.md -rw-r--r-- 1 root root 3445 Oct 25 03:54 settings.conf
Create a tarball of your code.
$ tar czf mydumpadmin-1.0.tar.gz mydumpadmin-1
Step 5 – Create SPEC File
Create a spec file ~/rpmbuild/SPECS/mydumpadmin.spec using below content.
~/rpmbuild/SPECS/mydumpadmin.spec
Name: mydumpadmin Version: 1 Release: 0 Summary: An Advance Bash Script for MySQL Database Backup Group: TecAdmin BuildArch: noarch License: GPL URL: https://github.com/tecrahul/mydumpadmin.git Source0: mydumpadmin-1.0.tar.gz %description Write some description about your package here %prep %setup -q %build %install install -m 0755 -d $RPM_BUILD_ROOT/etc/mydumpadmin install -m 0600 credentials.txt $RPM_BUILD_ROOT/etc/mydumpadmin/credentials.txt install -m 0755 mysql-dump.sh $RPM_BUILD_ROOT/etc/mydumpadmin/mysql-dump.sh install -m 0644 README.md $RPM_BUILD_ROOT/etc/mydumpadmin/README.md install -m 0644 settings.conf $RPM_BUILD_ROOT/etc/mydumpadmin/settings.conf %files /etc/mydumpadmin /etc/mydumpadmin/credentials.txt /etc/mydumpadmin/mysql-dump.sh /etc/mydumpadmin/README.md /etc/mydumpadmin/settings.conf %changelog * Tue Oct 24 2017 Rahul Kumar1.0.0 - Initial rpm release
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 ~/rpmbuild $ rpmbuild -ba SPECS/mydumpadmin.spec
After successful built, a rpm file will created like ~/rpmbuild/RPMS/noarch/mydumpadmin-1-0.noarch.rpm
Install your rpm using the below command. After install check, the files are properly installed as defined location.
$ rpm -ivh mydumpadmin-1-0.noarch.rpm
Thank You for using this article. I hope above steps will help you to create your own rpm.

thankyou! your tutorials are greate .
Hi,
We have custom scripts to perform certain installation with require dynamic inputs to be passed at the time we run the script which cannot be achieved using RPM packages. I want to understand if there is a way we can still use our own scripts,gather post installation information and create a SPEC file(no installation). May be just the below information:
Name: mydumpadmin
Version: 1
Release: 0
Summary: An Advance Bash Script for MySQL Database Backup
Group: TecAdmin
BuildArch: noarch
License: GPL
URL: https://github.com/tecrahul/mydumpadmin.git
Source0: mydumpadmin-1.0.tar.gz

Write some description about your package here
With no source, can we package and create an RPM package with the above requirements?
If I have to create a general package and then 3 others installation that change only some parameter in some text file, how this can be done?
Where can I find my installed package?
Hi Abhishek, The file locations of the installed file will be the same as defined in the .spec file.
if i want to add another require RPMS before i install my script how to add as example want to include “yum install rsync ” in my rpm package how i can do that ?
You can use Requires tag to install dependencies for your package
http://wiki.rosalab.ru/en/index.php/RPM_spec_file_syntax#Requires.2C_Obsoletes.2C_Provides.2C_Conflicts.2C_etc.
Only One little problem. The Group tag “Rahul” is invalid. For a list of usable groups check out:
/usr/share/doc/rpm-/GROUPS
I was preparing a new rpm to take backup of /root/Downloads/webmin to /var/tmp/webmin.tar.gz
I installed the newly built rpm package but not able to see the package in rpm -qa output.
[root@localhost noarch]# rpm -qa | grep -i webmin1-1-0.noarch.rpm
[root@localhost noarch]#
Can anybody let me know how can this be solved ?
