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 (add these lines to the /etc/sysconfig/iptables before the REJECT all else) :
-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

now run: service iptables restart

  • Install git (and emacs ;-).
  • Make a dirac user, and copy the hostcert/key into .globus
  • su - dirac
  • Set git up correctly:
    git config --global user.name "Your Name"
    git config --global user.email you@example.com
  • 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
     eval "$(ssh-agent)"  followed by ssh-add -t 1h
  •  git clone git@github.com:ic-hep/DIRAC-tools.git 
  •  DIRAC-tools/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 :-)

  • take ownership of the bug/feature you want to fix
  • make a branch: Example: The branch is bug1 and the modified file is ConfigurationSystem/Client/CSCLI.py:
 cd /opt/dirac/DIRAC
 git status (should say "# On branch rel-v6r12")
 git pull
 git branch bug1
 git checkout bug1 
 git status (should say "# On branch bug1")
  • now add your code/restart the relevant components and test 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 using the Edit button in the top right corner !!)
  • Finally: Switch back to main branch
 git checkout rel-v6r12
and delete the local copy of the bug1
 git branch -d bug1
