RHEL 6 question

block921

Anyone know how to create a single rpm that installs hello.sh in /root/bin with 755? The stupid answer isn't in the useless work book and I had to drop from the virtual class so I missed the answer

Why do you want to do this in an RPM instead of creating a tar that allows you to unpack it as required with any user account and location?

Perhaps you can find your answers here: https://pmc.ucsc.edu/~dmk/notes/RPMs/Creating_RPMs.html

Building a simple RPM is an objective for the RCHE exam

Good to know

For a simple RPM like you could do the following:

Create the required directories

# mkdir -p /usr/src/redhat/{BUILD,RPMS,SOURCES,SPEC,SRPMS,tmp}

Install the required packages:

# yum install -y rpm-build

Create the BASH file (mine is blank for this example):

# mkdir /usr/src/redhat/SOURCES/sample
# touch /usr/src/redhat/SOURCES/sample/hello.sh

Create a SOURCES file that will actually only hold your single BASH script:

# tar cvf sample.tar.gz /usr/src/redhat/SOURCES/sample
# mv sample.tar.gz /usr/src/redhat/SOURCES

Create a sample.spec file in the /usr/src/redhat/SPEC directory using the following as a template:

##### Sample SPEC File #####

Summary: This package is a sample for the Red Hat exams.
Name: sample
Version: 1.0
Release: 0
License: GPL
Packager: Joe Tester
Group: Development/Tools
Source: %{name}.tar.gz
BuildRoot: /usr/src/redhat/tmp/%{name}-%{version}

%description
This package is just a sample for the Red Hat exams.

# The %prep and %setup untar your SOURCES .tar.gz file and enter into that directory to perform the required actions.

%prep
%setup -n sample

# Moves the hello.sh file into the /opt directory (only under our build root).

%install
mkdir -p "$RPM_BUILD_ROOT/opt/"
cp -R * "$RPM_BUILD_ROOT/opt/"

# All files you want in your RPM package must be listed here.
# Listed directories contain every file and sub-directory within them.

%files
/opt/

%clean
rm -rf "$RPM_BUILD_ROOT"

%post
chown user01:user01 -R /opt/hello.sh
chmod 775 -R /opt/

##### End SPEC File #####

Once your SPEC file is in place and your sample.tar.gz is in place execute the following command to create the new RPM package:

# rpmbuild -v -bb /usr/src/redhat/SPEC/sample.spec

If there are any errors you will see them here and they should be easy enough to fix. If there are no errors you should now have a new RPM package in your /usr/src/redhat/RPMS directory.

Run the following to test:

# rpm -ivh sample.rpm

Which in turn should install the hello.sh script into the /opt directory with the 775 permissions and owned by user01 and group user01.

This should be everything that you need. If you get stuck or have any questions let me know.

just to be fair it also says we have to sign the rpm with a self signed cert and then make it available via custom yum repo:

gpg -gen-key
gpg --export a 'name' > public_key.txt
gpg --list-keys

vi ~/.rpmmacros
%_signature gpg
%_gpg_name <name used in key>

rpm --resign file.rpm

doesn't work, it has someting to do with %setup -n sample, whats the difference between setup -q and setup -n ?

What error are you getting? If you follow the output that is produced from the -v option with the rpmbuild command it should indicate where you issue is. The %prep and %setup essentially untar your sample.tar.gz file and the -n sample means the name of the directory it is expecting to cd into is "sample".

Hello thanks for the brief and concise RPM template. I hope this is thread still opened. But i need your help to help to debug the issue. I am getting this error:
[root@SPECS]# rpmbuild -v -bb ntp.spec
error: line 19: second %prep

Basically I am doing litterly everything you had posted. I am trying to create a simple RPM with binary and startup script but need to be in RPM format to be installed in repo during installs. Thanks again.
