Step 1: Requirements

1. Name your nodes and register them in the DNS

If the machines you are installing/configuring are not yet registred in the DNS, we suggest to use names like grid001, grid002, grid003. Of course it is only a suggestion and not a mandatory requirement.
To minimise problems, it is recommended that the grid machines (CE, SE, WN) are either outside your company's firewall or have "full-IP" permissions.

2. Request to the CA the certificates for your nodes.

As for users, some Grid Elements must be authenticated with digital certificates too. 
To join GILDA Test Bed, it is recommended to request GILDA host certificates to GILDA CA.

If compatible, you can alternatively request the host certificates to your country CA (a list is provided in http://marianne.in2p3.fr/datagrid/ca/ca-table-ca.html).

For example, in the case of Italy,  the INFN procedure isdocumented here:

Please note that in order to request a server certificate, you need to have your personal certificate. If you haven't got it, please follow the procedure described in the Users requirements section.

3. Collect ethernet MAC address

MAC address are needed to setup DHCP service for the first installation: collect all the MAC address of the grid elements to install.

4. Disable Hyperthreading and enable PXE boot

If your nodes support Intel Hyperthreading (e.g. Xeon) we suggest to disable it directly in the BIOS configuration. Although well supported by Linux, it does not give you any 'magic' improvement. If you plan to use PXE to install your nodes, ensure that the boot sequence is OK.
