Installation toolkit and deployment of Globus in Pisa

1
Installation toolkit and deployment of Globus in
Pisa

• Development of a toolkit for installation of
  Globus
• Setup and test of Globus in Pisa

Development of a toolkit for installation of
Globus (1) -- Why should we do it?

• globus.org does not provide an installation
  toolkit and a precompiled package.
• Pisa is part of the Globus deployment taskforce
  inside the INFN-GRID project. Our goal is to
  automatize and standardize the installation
  procedure of Globus for INFN test-beds.

Development of a toolkit for installation of
Globus (2)--Design and implementation

• We compile the Globus package and distribute it
  with our toolkit of semi-automatic installation.
• Our toolkit includes two major scripts written in
  bash one for installation and the other for the
  system configuration.
• The toolkit is designed in modules user can run
  one or all steps of the procedure use the INFN
  or the default setup.

Installation script menu System setup
script menu

• (1) modify system files and reactivate the inetd
  daemon
• (2) change owner to root of certain files for
  tighter security
• (3) modify system wide login files
• (4) start/restart Globus now
• (5) configure gsi-wuftpd and restart the inetd
  daemon
• (6) configure gdmp and start the gdmp_server
• (q) Quit
• (h) Help

• (1) Copy INFNGRID tar files from
  /afs/infn.it/project/infngrid/1.2/Linux to
  download dir
• (2) Decompress and untar INFNGRID distribution
  files in install dir
• (3) Configure INFNGRID software
• (4) Globus Setup
• (5) Configure GRAM services
• (6) Globus local deploy
• (7) GIIS Configuration
• (8) GDMP Installation
• (q) Quit
• (h) Help

Development of a toolkit for installation of
Globus (3)-- Does it work?

• The toolkit has been tested at several INFN
  sites, CERN and FNAL
• It has been tested on different platforms
  RedHat Linux 6.1, SunSolaris 2.6 (Ultra)
• It has been tested for the INFN setup (at INFN
  sites) and the default setup (at other sites).

Development of a toolkit for installation of
Globus (4)--Who we are and our plan

• F.Donno, A.Sciaba, A.Controzzi, Z.Xie
• Contact address grid-release_at_pi.infn.it
• An on-line manual of the toolkit can be found at
  http//www.pi.infn.it/GRID/
• Well continue to support the toolkit. Some new
  features are foreseen, however, no drastic change
  is expected before the next major release of
  Globus.

Setup and test of Globus in Pisa (1)--resources

• The following resources are available for testing
  Globus in Pisa
  one farm of 5 PC running Linux (CMS)
  one PC running Linux (ATLAS).
• There are 3 more PC arriving for the INFN-GRID
  project.

Setup and test of Globus in Pisa (2)--setup of a
PC farm

• PC1 acts as a gateway
• it is the local GIIS server and regularly it
  registers itself to the INFN central GIIS
• it is the gatekeeper who provides the GRAM
  service.
• PC2-PC5 are client machines.
• Globus is installed and deployed on PC1 and
  globus installation directory is mounted on
  PC2-PC5 via NFS.
