在 CentOS 8 中创建元包

Question

I'm trying to create a meta-package in CentOS 8 that installs vim and nano.

I built rpm-package via spec file. The spec file:

Summary: It's just a test meta_package
Version: 0.1 
Release: 1
Group: Applications/Internet
License: GPL 
BuildArch: noarch
Requires: nano, vim

%description
A test meta_package.

%prep 

%build

%install

%clean

%post
yum install -y nano
yum install -y vim

%files
%defattr(-,root,root)

%changelog

Building

rpmbuild --bb meta_package.spec

Then I launch it like

rpm -I meta_package-0.1-1.noarch.rpm

But packages haven't been installed. Is there any possible solution to that?

Answer 1

create a meta-package in CentOS 8 that installs vim and nano

file.spec: Missing line for package name, "Name:", and for files, "%files", eg /usr/local/share/Meta/meta.txt

Example.spec

Summary: It's just a test meta_package
Name: Nano_VIM 
Version: 0.1 
Release: 1
Group: Applications/Internet
License: GPL 
BuildArch: noarch
Requires: nano
Requires: vim

%description
A test meta_package.

%post
dnf install -y nano
dnf install -y vim-enhanced
    
%files
/usr/local/share/Meta/meta.txt

%changelog

Build a package: $ rpmbuild -bb Z-meta.spec

Install example (No package vim in CentOS 8 → it was a reinstall of the package to include vim-enhanced )

# dnf reinstall /home/knudfl/rpmbuild/RPMS/noarch/Nano_VIM-0.1-1.noarch.rpm

Reinstalled:

Note: Please always use yum or dnf for package install, "rpm -Uvh" doesn't take care of dependencies.

Answer 2

For meta-packages, you must not specify dependencies in the %post section.

You simply specify them with Requires: tag. Example:

Requires: nano
Requires: vim-enhanced

Then use a package manager like yum or dnf to satisfy dependencies at install time.
