3.2. Using Certificates

You can verify Globus is correctly installed by running a few simple Globus commands from your Frontend. Although this is only a simple loopback-grid this will verify the installation. The following will run grid-hostname over loopback on your Frontend node.

1. Create a proxy certificate.

   $ grid-proxy-init Your identity: /O=Grid/OU=San Diego Supercomputer Center/OU=rocks12.sdsc.edu/OU=sdsc.edu/CN=Spaceman Spiff Enter GRID pass phrase for this identity: Creating proxy ................................................ Done Your proxy is valid until: Tue Sep 9 10:53:51 2003

2. Run hostname over Globus

   $ globus-job-run localhost /bin/hostname rocks12.sdsc.edu

To start building a grid you will need to exchange certificate and grid-mapfile information with other hosts and users. Please visit the Globus site documentation to learn how to do this.
