创建RPM包可能很复杂。下面是一个简化的示例:

| Name: hello-world
Version: 1
Release: 1
Summary: Most simple RPM package
License: FIXME
%description
This is my first RPM package, which does nothing.
%prep
# we have no source, so nothing here
%build
cat > hello-world.sh <<EOF
#!/usr/bin/bash
echo Hello world
EOF
%install
mkdir -p %{buildroot}/usr/bin/
install -m 755 hello-world.sh %{buildroot}/usr/bin/hello-world.sh
%files
/usr/bin/hello-world.sh
%changelog
# let skip this for now
|
将文件另存为hello-world.spec。
安装依赖：
1
| yum -y install gcc rpm-build rpm-devel rpmlint make python bash coreutils diffutils patch rpmdevtools
|
然后执行：
1
2
| rpmdev-setuptree
rpmbuild -ba hello-world.spec
|
rpm-setuptree命令创建了几个工作目录。由于这些目录永久存储在$HOME中，因此不需要再次输入命令。
执行rpm-build命令的输出类似：
