Dirac in a box (Basic Setup)

  • Setup yourself up with a hostcert and a EMI UI, eg by following these instructions.
  • Open the relevant ports: 
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8443 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 9130:9200 -j ACCEPT
  • Install git (and emacs ;-).
  • Set git up correctly: 
    git config --global user.name "Your Name"
    git config --global user.email you@example.com
  • 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
  • Test your server.

Fixing a bug/adding a feature :-)

  • make a branch: Example: The branch is bug1 and the modified file is ConfigurationSystem/Client/CSCLI.py: 
 cd /opt/dirac/DIRAC
 git branch bug1
 git checkout bug1 
 git status (should say "# On branch bug1")
  • now add your code 
 git add ConfigurationSystem/Client/CSCLI.py
 git commit -m "CLI to accept ctrl-D"
 git status
  • and push it back to github 
 git push -u origin bug1
  • Now go to the git repo webpage and issue a pull request (ensuring to send the request to our (ic-hep) repo, not the main DIRAC repo - check the defaults !!)
