Before you begin:

• You may download the latest GRID Seed release from:

http://euindia.ictp.it/download/GridSeed/

• Notice: it is assumed that VMWare is already installed in your system; please refer to the following page for further instructions:

Starting the GRID Seed Virtual Machines:

To kickstart the grid you must follow a specific order when booting the variuos GRID services. First boot the central services, by launching the respective VM:

1. Start the DNS virtual machine:

   ./start.sh -t DNS -c 1 -m 256

   A DNS is essetial due to the grid's GSI: hostnames must be fully qualified FQADN as they will be forward and reverse resolved. The DNS VM will also launch a Certification Authority to issue certificates.

2. Start the VOMS virtual machine:

   ./start.sh -t VOMS -c 1 -m 256

   gLite GRIDS need a VOMS server to work; in fact, all other services need the public certificate of the VOMS server.

3. BDII

   ./start.sh -t BDII -c 1 -m 256

4. LFC

   ./start.sh -t LFC -c 1 -m 256

5. WMS

   ./start.sh -t WMS -c 1 -m 256

Now you can install a User Interface host, where all GRID client commands are found:

6. UI

   ./start.sh -t UI -c 1 -m 256

Finally, you launch as many GRID Sites as you want, by iterating over the following steps:

7. CE

   ./start.sh -t CE -c 1 -m 256

8. SE

   ./start.sh -t SE -c 1 -m 256

   Notice that you must supply the CE number which this SE is connected to: a menu will pop-up allowing you to choose the CE.

9. WN

   ./start.sh -t WN -c 1 -m 512

   Notice that you must supply the CE number which this WN is connected to: a menu will pop-up allowing you to choose the CE. Repeat this step for as many WN connected to the CE as you want.
