This is a guide on setup the Globus Online service to storge data on HPSS at KIT.

Components

  • GridFTP Server connected to HPSS-DSI
  • myProxy Server for managing and creating user proxies
  • OAuth Server for User logins to the globus-Online Endpoint at KIT.
  • Globus Online Web Interface.

Requirements

  • A working HPSS Frontend with HPSS Client software installed and configured.
  • A working GridFTP Server with a valid Grid Host certificate. (GridKa Host certificate)
  • A working HPSS-GridFTP-DSI compiled package
    • Notice: a HPSS-Fuse instead of DSI would also work.
  • A working Connection to an LDAP Server to authorized the user locally on the GridFTP server.
  • A Globus Online account if not already exists.
  • A valid Grid User certificate.

Installation

Hostname: archive-tgftp.lsdf.kit.edu OS: SL 6.4

  • Download and install Globus Connect server repository
# curl -LOs http://toolkit.globus.org/ftppub/globus-connect-server/globus-connect-server-repo-latest.noarch.rpm
# rpm --import http://www.globus.org/ftppub/globus-connect-server/RPM-GPG-KEY-Globus
# yum install globus-connect-server-repo-latest.noarch.rpm
  • Install
# yum install globus-connect-server

Configuration

  • Adapt the config files. Both files contain detailed information on configuration possibilities. Please check!
/etc/globus-connect-server.conf
/var/lib/globus-connect-server/myproxy-server.conf

Endpoint Creation

Now setup your Frontend GridFTP Server as an Endpoint for globus Online

# globus-connect-server-setup
  • The globus-connect-server-setup asks you for your Globus Online account name and password.
  • If you run globus-connect-server-setup many times you get this error message:
"You are not an admin of the MyProxy Delegation Service"
  • Solution: run as root:
# rm /var/lib/myproxy-oauth/myproxy-oauth.db

Usage with your Grid User Certificate

  • Login via ssh to a Host where you have your valid Grid user Certificate and the myproxy packae installed.
  • Create and store a credential on Myproxy Server which is the same as the Endpoint Server at KIT.
myproxy-init -s archive-tgftp.lsdf.kit.edu -l <LDAP username> -c 0
  • You will be prompted to enter your Grid user key password. You also will be prompted to set a so called MyProxy passphrase twice to protect your created credential on Myproxy Server. This password must be the same as your LDAP-Account!! This what I found to be able to login via OAuth. (Please check!)
  • Your credential will be saved on the MyProxy Server under
/var/lib/globus-connect-server/myproxy-ca/store
  • myproxy-init executes a script to create the user's Home directory structure with private/ public/.
/usr/local/bin/myproxy-accepted-credentials-mapapp <User Cert DN><LDAP name> 
  • In case myproxy-init has failed complaining about missing CA-cerificates download the CA certificates directory via:
myproxy-get-trustroots -s archive-tgftp.lsdf.kit.edu
