1) Before starting a new install, set up the environment variables:
RHEL4-32 bit: built on atlas-prod02.slac.stanford.edu
pacman version = 3.26
AFS: /afs/slac/g/atlas/d/ (currently soft linked to /b/)
| Code Block |
|---|
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
pacman version = 3.29
AFS: /afs/slac/g/atlas/c/
For some reason, it's necessary to unset PYTHONPATH
| Code Block |
|---|
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/.
| Code Block |
|---|
...
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
| Code Block |
|---|
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:
| Code Block |
|---|
...
. ~/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:
| Code Block |
|---|
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,
| Code Block |
|---|
...
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.
Check the status of the Production cache in the corresponding web page,
http://atlas-computing.web.cern.ch/atlas-computing/projects/releases/status/15.6.5.1/AtlasProduction/
which usually lists the DBRelease version number.
If it uses a new DBRelease version, scp the tar file over from lxplus.cern.ch and
put it in /c/DBRelease/ and "tar -xf" and move it as the way others are.
DBRelease tar files are stored in
/afs/cern.ch/atlas/www/GROUPS/DATABASE/pacman4/DBRelease/
This script will do all the work:
...
6) When there is an announcement of new AtlasLogin or AtlasSettings
Go to the install area (/c/ in this example) and execute:
| Code Block |
|---|
...
pacman -update AtlasLogin |
...
pacman -update AtlasSettings |
They are supposed to be backward compatible, unless stated otherwise.
