Dirac in a box

• Setup yourself up with a hostcert and a EMI UI, eg by following these instructions.
• Install git (and emacs ;-).
• Make a dirac user and copy the hostcert/key into .globus
• You also need the ssh key you use on github
• To save you from typos (the script does not deal well with that :-D ) use "ssh-add -t 1h"
• wget http://www.hep.ph.ic.ac.uk/~dbauer/dirac/dirac_in_a_box.py

•  ./dirac_in_a_box.py /opt/dirac/ git@github.com:ic-hep 

• Ignore "Exception _mysql_exceptions.ProgrammingError" errors

Get the code

• You need a github account and be a member of the ic-hep organization. Please contact Simon F. directly if you need access.

• Then you need to fork the repo

• In the example I'm using my own github login 'marianne013'(*) as I like to be able to do cut-and-paste when following my own instructions.

• As the dirac user do:

  git clone git@github.com:marianne013/DIRAC.git

  (from git page ssh). This will only work if the dirac user has a copy of your ssh key :-D

•  DIRAC/Core/scripts/dirac-deploy-scripts.py 

•  wget http://www.hep.ph.ic.ac.uk/~dbauer/dirac/full_sanitized.cfg 

• edit full_sanitized.cfg
  

1. Normal machine set-up (symlinking /etc/grid-security/certificates, etc...)
2. Checkout DIRAC

DIRAC/Core/scripts/dirac-deploy-scripts.py wget http://www.hep.ph.ic.ac.uk/~dbauer/dirac/full_sanitized.cfg

1. Edit full_sanitized.cfg
   1. Set Release = integration
   2. Set UseVersionsDir = no
   3. Edit TargetPath = /srv/localstage/ddirac
   4. Set ExtraModules = DIRACWeb
   5. Set SiteName etc...
   6. Comment Out WorkloadManagement/InputDataAgent
   7. Comment Out WorkloadManagement/TaskQueueDirector
   8. Turn off web interface
   9. Set DB Passwords

scripts/dirac-install -t server -X full_sanitized.cfg
source bashrc
dirac-configure -F full_sanitized.cfg
dirac-install-mysql
dirac-setup-site

(*) The first hit when putting Marianne013 into google entitled: "Marianne 013: Kühe in Ketten und Strapsen" which translates into "Cows in chains and suspenders." It's all downhill from there.
