Wget

To grab everything in subdirectory use:

wget -r -l0 --no-parent http://site.com/whatever/

Yum

create repo

yum -y install createrepo gcc
 
createrepo /var/dgiref/release/2009.2/i386/

Use it

cat /etc/yum.repos.d/dgiref.repo
[base]
name=DGIREF-$releasever - Base

yum will not install source rpms. You can download the

src rpm: x.src.rpm
then run: rpm -i x.src.rpm
which will put a file : x.spec in /usr/src/redhat/SPECS
Then run: rpmbuild -bb x.spec
which will put a rpm: x.rpm in /usr/src/redhat/RPMS
That rpm can be installed as usual: rpm -i x.rpm

Rpm

At the center of the action is RPM. It performs a number of steps during the build process:

• Executes the commands and macros in the prep section of the spec file.
• Checks the contents of the file list.
• Executes the commands and macros in the build section of the spec file.
• Executes the commands and macros in the install section of the spec file. Any macros in the file list are executed at this time, too.
• Creates the binary package file.
• Creates the source package file.

By using different options on the RPM command line, the build process can be stopped at any of the steps above. This makes the initial building of a package that much easier, as it is then possible to see whether each step completed successfully before continuing on to the next step.

Options

rpm -qip mtools-3.9.8-2.i386.rpm  print package summary
rpm -i mtools-3.9.8-2.i386.rpm install package
rpm -ivh mtools-3.9.8-2.i386.rpm install, monitor and verify pack
rpm -q mtools verify if pack installed
rpm -qa list all installed packs
rpm -ql mtools list all files installed for pack
rpm -qd mtools list pack doc files only
rpm -e mtools erase package
rpm -Uvh * upgrade all packs in distribution
rpm -qf `which mtv` search pack mtv

Binary RPM

From Dgiref Jump to: navigation, search

The binary package file is the one part of the entire RPM building process that is most visible to the user. It contains the files that comprise the application, along with any additional information needed to install and erase it. The binary package file is where the "rubber hits the road."

Build rpm

install rpm-build in SL

yum -y install rpm-build gcc

build rpm from tar.gz

rpmbuild -ta package-XXX.tar.gz
ls /usr/src/redhat/RPMS/[arch]/
> package-XXX.[arch].rpm
