Background

SLAC install has some differences

  • all files kept in AFS
  • centralised configuration
  • mount of disk partition for data
  • move of mysql database storage to separate partition
  • use of apache redirect for calls

AFS

  • symlinked /opt/perfsonar to /afs/slac.stanford.edu/package/perfSONAR-PS/dist/
  • config files kept in /afs/slac.stanford.edu/package/perfSONAR-PS/etc/
    • each file is named to appropriate service
  • customisations on init.d files to reflect above
    • install file located at /afs/slac.stanford.edu/package/perfSONAR-PS/etc/init.d/
    • will delete services from install and put in new ones with pointers to new config files
    • add's chkconfig stuff

Partitions

  • largest disk partition mounted at /var/lib/perfsonar for data
  • mysql
    • mv /var/lib/mysql /var/lib/perfsonar/
    • sudo ln -sf /var/lib/perfsonar/mysql/ mysql
