Release 1.0 was the first official release of the PoC software, based on the
list
that was handed down by the VleIT. This release was presented on the
VL-e workshop on April 7th 2006. It was released both on this website and
on DVD-ROM.
The software has been bundled as an
apt-getable and yum-installable repository of RPM packages. This bundle can be
installed on any Red Hat Enterprise Linux 3 compatible distribution.
The LCG 2.7 middleware is not bundled with this distribution, but can be installed separately with YAIM. The PoC installer script will do this automatically. There is also a YAIM function for installing the PoC on existing YAIM installations.
The full set of the PoC software is obtained by installing one of two meta-RPMs,
vl-e-ui for user interfaces or vl-e-wn for worker nodes
(this is a subset without the graphical user interface tools).
Since the PoC 1.0 release, numerous updates have been made to the PoC distribution
software.
Our policy is, that if you install the PoC from this website that you will always
receive the latest updates. We label this release simply as 1. It
consists of the PoC 1.0 release plus all updates since April 7th, 2006. The latest
release can be found here.
Thus, strictly speaking, it is no longer possible to install the original
PoC 1.0 software release from this website. If you insist on installing the
original code base, then remove the updates channel from the
/etc/apt/sources.list.d/vle.list file before doing an
apt-get install vl-e-ui.
Note: These installation instructions will install the latest R1 release, not 1.0
The easiest way to install the PoC is to download the PoC installer, and run it as root. This will install
a LCG UI and the vl-e-ui package, without asking a lot of questions.
Site adminstrators with their own LCG-YAIM 2.7 installation can use the vle-yaiminstaller RPM and issue the command
/opt/lcg/yaim/scripts/run_function ⟨SITE-INFO-DEF⟩ install_vle_poc
This will install the PoC vl-e-ui and/or
vl-e-wn based on the node type of the machine.
There is also a manual procedure outlined below.
The PoC requires a Red Hat Enterprise Edition 3 compatible installation to run. These include CentOS 3 and Scientific Linux 3. Other distributions are not guaranteed.
In addition to the base OS installation the following packages must be installed to fulfill all the dependencies:
These can all be obtained from the original base OS distribution, either from the internet or from the original installation media. The automatic PoC installer can also fetch these packages for you.
The PoC requires the j2sdk 1.4.2 RPM from SUN. This RPM can not be redistributed due to license restrictions; download it from Sun and install it manually.
We've settled on JPackage for common java packages such as log4j, lucene,
etc. Their software can be installed with apt or yum just like the PoC. The automatic PoC installer
will deal with this automatically; instructions on how to add the repository to your package
management configuration manual is found below (or see the JPackage website).
You can browse the repository and basically install any or all of the rpms found in the RPMS.vle directory. Resolving dependencies is up to you, which is why you really want one of the semi-automated methods below.
All RPMS are signed with GPG. You can import the GPG key into the RPM database by typing rpm --import http://poc.vl-e.nl/distribution/1.0/RPM-GPG-KEY-vle, but if you don't trust this you should contact one of the release managers personally to obtain the public key.
Apt is the Debian package management tool; it is the default tool used by the PoC installer because it is also used by YAIM for installing the LCG middleware.
Download the VL-e public key from http://poc.vl-e.nl/distribution/1.0/RPM-GPG-KEY-vle or contact us directly. Download the JPackage Project key from http://www.jpackage.org/jpackage.asc.
Import the keys as root:
rpm --import RPM-GPG-KEY-vle rpm --import jpackage.asc gpg --import RPM-GPG-KEY-vle gpg --import jpackage.asc
