0) HN/e-news announcement of new release pacman package
https://groups.cern.ch/group/hn-atlas-releaseKitAnnounce/default.aspx
1) Before starting a new install, set up the environment variables:
RHEL4-32 bit: built on atlas-prod02.slac.stanford.edu:
export PATH=/bin:/usr/bin:/usr/etc:/usr/afsws/bin:/usr/afsws/etc:/usr/bin/X11:. . /afs/slac/g/atlas/packages/pacman/3.26/setup.sh
RHEL5-32 bit: built on atlas-prod05.slac.stanford.edu:
export PATH=/bin:/usr/bin:/usr/etc:/usr/afsws/bin:/usr/afsws/etc:/usr/bin/X11:. unset PYTHONPATH . /afs/slac/g/atlas/packages/pacman/3.29/setup.sh
2) Go to the target release partitions, /c/ or /d/.
cd /afs/slac/g/atlas/c # for example RHEL5-32bit
Makes sure there is enough space with " fs lq * ".
There are 17 more AFS partitions mounted, in addition to the /c/ partition.
If more space is needed, send a request to unix-admin@slac.stanford.edu
(All examples below will assume installation in /c/)
3) Installing base release: x.x.x
Issue the pacman command found in the HN/e-news announcement, and direct to pacman.log
pacman -allow any-platform trust-all-caches tar-overwrite -get http://atlas-computing.web.cern.ch/atlas-computing/links/kitsDirectory/projects/cache:AtlasProduction_15_6_5_i686_slc5_gcc43_opt>> pacman.log &
4) Installing AtlasProduction cache: x.x.x.x
After steps 1-3, setup the release:
. ~/reldirs/15.6.6/cmthome/setup.sh -tag=15.6.6,32
Issue the pacman command found in the HN/e-news announcement, and direct to pacman.log. For example:
pacman -get http://cern.ch/atlas-computing/links/kitsDirectory/Production/cache:AtlasProduction_15_6_5_1_i686_slc5_gcc43_opt >> pacman.log &
Note1: After the install is finished,
cd /afs/slac/g/atlas/c/AtlasProduction/15.6.5.1/AtlasProductionRunTime/cmt/ cmt config
Note2: If the AtlasProduction package requires a new DBRelease, it has to be downloaded manually:
pacman trust-all-caches -get http://atlas.web.cern.ch/Atlas/GROUPS/DATABASE/pacman4/DBRelease:DBRelease-current
See https://twiki.cern.ch/twiki/bin/viewauth/Atlas/AtlasDBRelease
5) Problems with release install
Check the postings in https://groups.cern.ch/group/hn-atlas-releaseKitProblem/default.aspx
as others might have similar problems.
Ask Peter or Zach.
If all fails, start a new thread in that forum.
If you ran out of disk space during an install, manually download the last missing tarball with a command like:
wget http://atlas-computing.web.cern.ch/atlas-computing/links/kitsDirectory/projects/kits/AtlasAnalysis_16_5_0_i686_slc5_gcc43_opt.tar.gz
6) When there is an announcement of new AtlasLogin or AtlasSettings
Go to the install area (/c/ in this example) and execute:
pacman -update AtlasLogin pacman -update AtlasSettings
They are supposed to be backward compatible, unless stated otherwise.
7) Updating pacman:
There are usually ATLAS announcements asking to install a new version.
New version of pacman can be downloaded from BU:
wget http://physics.bu.edu/pacman/sample_cache/tarballs/pacman-latest.tar.gz tar -xf pacman-latest.tar.gz
Move the pacman package to /afs/slac/g/atlas/packages/pacman/, go into the new
pacman directory and set up.
cd x.xx source setup.sh
(Please note that any installs in /c/ or /d/ must stay with the pacman version
that was originally used. pacman does not get updated often, but when it does
it might be a good time to build a new install with it switching between
/c/ and /d/.)
