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

%packager YOUR_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

%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 Kumar  1.0.0
  - 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.
