Description of the installation system

• inst.lcg.cscs.ch holds the following services: DHCP PXE TFTP HTTP HTTP_PROXY
  • DHCP is configured via Puppet
  • PXE and TFTP are run from /cm mounted in read-only mode.
  • HTTP is running two things:
    1. On port 81 on /cm/www/html/ mounted in read-only mode, serving all CM tree (i.e. a RPM repo).
    2. On port 80 running a transparent proxy to phoenix1.lcg.cscs.ch for Razor server.
• phoenix1.lcg.cscs.ch runs the razor server and puppet+puppetdb server.
  1. 1. The HTTP repo runs off /cm/www/html/ and is shared with inst.lcg.cscs.ch
• cfengine.lcg.cscs.ch runs cfengine for all those machines still configured via CFengine2
