103 grid-ca-sign -in /root/hostcert_request.pem -out /root/hostcert.pem mycapw Then, ftp the file /root/hostcert.pem back to the server machine and place it in the directory /etc/grid-security. B.2.10 Requesting and Signing User Certificates For each user who will use the grid (in our example, user snobol on the client machine m1), the following procedure must be executed by the user and Certificate Authority. On the snobol user’s logon, run: grid-cert-request The user should make up his own passphrase for his certificate. He will use this same passphrase later with the grid-proxy-init command to authenticate with the grid. In our example, the snobol user’s login password could be used here. The user must then send the file /home//.globus/usercert_request.pem to the Certificate Authority (machine m2) for signing. On the CA machine (m2), sign the certificate using root with the following command, adjusting the location of usercert_request.pem to point to wherever the above request file is now stored on m2: grid-ca-sign -in usercert_request.pem -out usercert.pem mycapw Securely send the file usercert.pem back the requesting user. The user should put the file usercert.pem into his /home//.globus directory. The user should also be added to the grid-mapfile (on machine m2 under root) using the following command (note the backward apostrophe characters next to the double quote characters): grid-mapfile-add-entry -dn “`grid-cert-info -f usercert.pem –subject`” –ln globususer Copy grid-mapfile in /etc/grid-security/grid-mapfile to each of the other servers (m2) so that all of the servers have this file. B.2.11 Setting Up the Gatekeepers On each server (m2 and m3), add the following two lines to the file /etc/services: gsigatekeeper 2119/tcp #globus gatekeeper gsiftp 2811/tcp #globus wuftp Create the file /etc/xinetd.d/gsigatekeeper on each server, containing the lines:
104 service gsigatekeeper { socket_type = stream protocol = tcp wait = no user = root env = LD_LIBRARY_PATH=/usr/local/globus/lib server = /usr/local/globus/sbin/globus-gatekeeper server_args = -conf /usr/local/globus/etc/globus-gatekeeper.conf disable = no } Create the file /etc/xinetd.d/gsiftp on each server, containing the lines: service gsiftp { instances = 1000 socket_type = stream wait = no user = root env = LD_LIBRARY_PATH=/usr/local/globus/lib server = /usr/local/globus/sbin/in.ftpd server_args = -l -a -G /usr/local/globus log_on_success += DURATION USERID log_on_failure += USERID nice = 10 disable = no } Now reboot all of the machines. B.3 Setting Up the MDS We will configure the Monitoring and Discovery Service (MDS) to have one Grid Information Index Service (GIIS) in the machine m2, which collects the data reported by the Grid Resource Information Servers (GRIS) in all of the machines. The GRIS servers send information about their respective servers to the GIIS. In the demo application, we will use this to find machines that are not too busy. The user will be able to query the GIIS from the client machine m1.
