2 - Install and configure gLexec on your WNs

Changed:
<
<
We recommend to install the EMI version of gLexec (and obviously EMI WN!). So that plan the migration to EMI of your farm
>
>
We suggest you upgrade the WNs to EMI-3 so you install the latest gLExec version.

Briefly the steps are the following:

  • Installation: yum install glexec-wn

  • Configuration: set at least the mandatory variables (and in case some of the default ones if you need a different value for them)
tipically set the following in services/glite-glexec_wn: GLEXEC_WN_SCAS_ENABLED="no"

GLEXEC_WN_ARGUS_ENABLED="yes"

GLEXEC_WN_OPMODE="setuid"

 
Changed:

EMI Case

You may have a look at the following notes to see how to install gLexec on your WNs. If you have lsf as batch system or the WNs already installed, please focus your attention on the gLexec part of those notes

  • Yaim: (example of WN with torque and MPI) /opt/glite/yaim/bin/yaim -c -s site-info.def -n MPI_WN -n WN -n TORQUE_client -n GLEXEC_wn

gLite Case

follow this guide in order to install the ig_GLEXEC_wn metapackage: the configuration files and the yaim variables to set are the same
