IGI (based on gLite 3.2 release) 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

With standard installation of SL5 it's possible that you have the EPEL repository enabled. Please disable it:

# mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.disabled

otherwise you'll get the following error:

Missing Dependency: libcares.so.0()(64bit) is needed by package glite-security-gss-2.0.0-3.sl5.x86_64 (glite-generic_sl5_x86_64_release)

because of the presence of newer version of c-ares (1.4.0-1.el5). The middleware needs the 1.3.0-4.sl5 !

Remeber to enabled the dag.repo :

With standard installation of SL5 it's possible that you have the DAG repository. Please check if it is enabled, if no please enabled it:

cat /etc/yum.repos.d/dag.repo

.... enabled=1 ....

Common repositories

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.

Profile-specific repositories

Furthermore each profile needs a set of repositories that contain the profile-related middleware. Look at the table below to know what specific repositories your profile needs:

Metapackages Profile-specific repositories *x86_64*Sorted ascending
ig_ARGUS glite-argus.repo
ig_BDII_site glite-bdii_site.repo
ig_BDII_top glite-bdii_top.repo
ig_CREAM_torque glite-cream_torque.repo
ig_FTA_oracle glite-fta_oracle.repo
ig_FTM glite-ftm.repo
ig_FTS_oracle glite-fts_oracle.repo
ig_HLR glite-generic.repo
ig_GLEXEC_wn glite-glexec.repo
ig_LB glite-lb.repo
ig_LFC_mysql glite-lfc_mysql.repo
ig_SE_dcache_info glite-se_dcache_info.repo
ig_SE_dcache_nameserver_chimera glite-se_dcache_nameserver.repo
ig_SE_dcache_pool glite-se_dcache_pool.repo
ig_SE_dcache_srm glite-se_dcache_srm.repo
ig_SE_dpm_mysql glite-se_dpm_mysql.repo
ig_VOBOX glite-vobox.repo
ig_VOMS_mysql glite-voms_mysql.repo
ig_VOMS_oracle glite-voms_oracle.repo
ig_WN_torque, ig_WN_torque_noafs glite-wn_torque.repo
ig_WN, ig_WN_noafs
ig_WN_LSF, ig_WN_LSF_noafs
ig_SE_storm_gridftp ig-storm_gridftp.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).
