Linux RedHat How To Create An RPM Package -

1. Install Required RPM-Build Packages

$yum install rpm-build rpmdevtools

2. Create the directory structure

$rpmdev-setuptree

The directory structure will look like this

$ls -l rpmbuild/
total 24
drwxr-x--- 4 root root 4096 Nov 6 11:59 BUILD
drwxr-x--- 2 root root 4096 Nov 6 12:00 BUILDROOT
drwxr-x--- 3 root root 4096 Nov 6 11:20 RPMS
drwxr-x--- 2 root root 4096 Nov 6 11:03 SOURCES
drwxr-x--- 2 root root 4096 Nov 6 11:58 SPECS
drwxr-x--- 2 root root 4096 Nov 6 12:00 SRPMS

3. Create rpmmacro File

~/.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

4. Copy your script and files under SOURCES directory

$cd ~/rpmbuild/SOURCES
$ls -l myadminscript-1/
total 8
-rwx------ 1 root root 31 Nov 12 09:53 myscript.sh
-rw-r----- 1 root root 24 Nov 12 09:54 README.md

5. Create a tarball of your code.

$tar -czf myadminscript-1.tar.gz myadminscript-1

6. 6. Create SPEC File

~/rpmbuild/SPECS/myadminscript.spec

Name:  myadminscript
Version: 1
Release: 1
Summary: Write a summary here to explain what your code does


Group: TecAdmin
BuildArch: noarch

URL: https://github.com/nareshpadiyar/myadminscript.git
Source0: myadminscript-1.tar.gz

7. Build RPM

$rpmbuild -ba ~/rpmbuild/SPECS/myadminscript.spec

Sample Output

$rpmbuild -ba ~/rpmbuild/SPECS/myadminscript.spec

8. After successful built, a rpm file will created like ~/rpmbuild/RPMS/noarch/myadminscript-1-1.noarch.rpm

9. Install your rpm using the below command. After install check, the files are properly installed as defined location.

$ rpm -ivh myadminscript-1-1.noarch.rpm
