(r2) CrabOnUbuntu1204 < Sandbox

---++ How I made GSI stuff work for me on Ubuntu 12.04 so I can run Crab on my laptop

---+++ CVMFS and CMSW and Grid stuff (including automatically up to date certificated and CRL's)

   * Install CVMFS
      * followed online documentation
      * pus: =CVMFS_HTTP_PROXY='DIRECT'= (from David A.)
   * mount
      * =/cvmfs/cms.cern.ch=
      * =/cvmfs/grid.cern.ch=

   * now can create a CMSSW release
<verbatim>
cd /home/belforte/STEFANO/WORK/CRAB/CMSSW/
cmsrel CMSSW_7_0_2
cd CMSSW_7_0_2
cmsenv
</verbatim>

   * but can't do scram b, so I have to copy the directory from lxplus in order to run customized cmsRun
      * OTOH cmsRun and EdmConfigHash run

---+++ GSI part

   * install =globus-proxy-utils= via synaptic
   * in my =.bashrc=
<verbatim>
export X509_CERT_DIR=/cvmfs/grid.cern.ch/etc/grid-security/certificates
export X509_VOMSES=/cvmfs/grid.cern.ch/emi-ui-3.7.3-1_sl6v2/etc/vomses
export X509_VOMS_DIR=/cvmfs/grid.cern.ch/emi-ui-3.7.3-1_sl6v2/etc/grid-security/vomsdir
export X509_USER_PROXY=/tmp/x509up_u`id -u`
</verbatim>

   * and since =voms-proxy-init= in =globus-proxy-utils= is old and does not know to look in X509_VOMSES
<verbatim>
mkdir ~/.glite
ln -s /cvmfs/grid.cern.ch/emi-ui-3.7.3-1_sl6v2/etc/vomses  ~/.glite/vomses
</verbatim>
   * alternatively could simply run /cvmfs/grid.cern.ch/emi-ui-3.7.3-1_sl6v2/usr/bin/voms-proxy-init

   * as root, added a  symlink, see http://askubuntu.com/questions/342484/etc-pki-tls-certs-ca-bundle-crt-not-found
<verbatim>
mkdir -p /etc/pki/tls/certs/
cd /etc/pki/tls/certs/
ln -s /etc/ssl/certs/ca-certificates.crt ./ca-bundle.crt
</verbatim>

   * now =gsissh=. See http://askubuntu.com/questions/249881/how-do-i-install-globus-toolkit-5-2 and http://www.astro.gla.ac.uk/~matthew/blog/?p=476
<verbatim>
 wget http://www.globus.org/ftppub/gt5/5.2/5.2.3/installers/repo/globus-repository-5.2-stable-precise_0.0.3_all.deb
sudo dpkg -i globus-repository-5.2-stable-precise_0.0.3_all.deb
sudo apt-get update
sudo apt-get install gsi-openssh-clients
</verbatim>

---+++ CRAB part
   * installed locally CRAB_2_10_7_pre1 from tarball so that can edit

   * finally to setup the crab environment
<verbatim>
source /cvmfs/cms.cern.ch/cmsset_default.sh 
#source /cvmfs/grid.cern.ch/emi-ui-3.7.3-1_sl6v2/etc/profile.d/setup-emi3-ui-example.sh 
cd /home/belforte/STEFANO/WORK/CRAB/CMSSW/CMSSW_7_0_2
cmsenv
cd  /home/belforte/STEFANO/WORK/CRAB/TESTCRAB

source /home/belforte/STEFANO/WORK/CRAB/CRAB_2_10_7_pre1/crab.sh 
</verbatim>

   * now crab -create works

   * and now also crab -submit and crab -status work

---++++ NOTES
   * no myproxy-* yet, need to use =dont_check_proxy=1= in crab.cfg
