The EGI / WLCG grid infrastructure can be accessed from any Nikhef-managed machine running a variant of Red Hat Enterprise Linux 6 or higher (e.g. CentOS 6 or 7). In order to use the grid middleware tools, type
source /cvmfs/grid.cern.ch/etc/profile.d/setup-cvmfs-ui.sh ## bash/ksh/zsh
first. Csh users will have to first run
/bin/bash
or perhaps even better, change their login shell to bash or zsh.
Sourcing the setup script will set up all required environment variables for running the middleware commands.
Type
voms-proxy-init --voms <YOUR-VO>
to create a voms proxy. Sample output:
$ voms-proxy-init -voms pvier Enter GRID pass phrase: Your identity: /O=dutchgrid/O=users/O=nikhef/CN=Some User Creating temporary proxy .......................................... Done Contacting voms.grid.sara.nl:30000 [/O=dutchgrid/O=hosts/OU=sara.nl/CN=voms.grid.sara.nl] "pvier" Done Creating proxy ................................................................... Done Your proxy is valid until Fri Dec 7 00:08:49 2007
Congratulations! You are now ready to use grid middleware tools.
