IGI (based on gLite 3.2) Installation and Configuration


Line: 45 to 47
 Each profile needs a set of common repositories:

Common repositories *x86_64*
  In order to have a working IGI service you have to download also the gLite repo files. In the table bellow you'll find the match from metapackages to profiles.
Line: 81 to 83
ig_WN, ig_WN_noafs
ig_WN_LSF, ig_WN_LSF_noafs
ig_WN_torque, ig_WN_torque_noafs glite-wn_torque.repo
Then update your host:
yum clean all

CAa installation:

Install CAs on ALL profiles:

yum install ca-policy-egi-core

Metapackage installation

Please consider that x86_64 WN profiles has to be installed using the “groupinstall” yum command as follows:

 yum groupinstall <WN_profile>  

where <WN_profile> could be one of: ig_WN, ig_WN_noafs, ig_WN_torque, ig_WN_torque_noafs, ig_WN_LSF, ig_WN_LSF_noafs or

 yum groupinstall <UI_profile>  

where <UI_profile> could be one of: ig_UI, ig_UI_noafs

If you are installing any othere profiles use:

 yum install <metapackage> 

Where <metapackage> is one of those reported on the table above ( Metapackages column).


IGI (based on EMI) Installation and Configuration


OS installation

Install SL5 using SL5.X repository (CERN mirror) or one of the supported OS (RHEL5 clones).

You may find information on official repositories at Repositories for APT and YUM
If you want to set up a local installation server please refer to Mrepo Quick Guide

NOTE: Please check if NTP , cron and logrotate are installed, otherwise install them!

Check the FQDN hostname

Ensure that the hostnames of your machines are correctly set. Run the command:

 hostname -f

It should print the fully qualified domain name (e.g. prod-ce.mydomain.it). Correct your network configuration if it prints only the hostname without the domain. If you are installing WN on private network the command must return the external FQDN for the CE and the SE (e.g. prod-ce.mydomain.it) and the internal FQDN for the WNs (e.g. node001.myintdomain).

Repository Settings

To have more details to the repository have a look to the this link Repository Specifications

If not present by default on your SL5/x86_64 nodes, you should enable the EPEL repository (https://fedoraproject.org/wiki/EPEL)

You need to have enabled only the above repositories (Operating System, EPEL, Certification Authority, EMI):

Common repositories *x86_64*
