Starting the GRID
How to kickstart the GRID: running GRID Seed.
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:
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.
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.
BDII
./start.sh -t BDII -c 1 -m 256
LFC
./start.sh -t LFC -c 1 -m 256
WMS
./start.sh -t WMS -c 1 -m 256
Now you can install a User Interface host, where all GRID client commands are found:
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:
CE
./start.sh -t CE -c 1 -m 256
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.
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.
