Notes about Installation and Configuration of a Site BDII - EMI-2 - SL6 x86_64

  • These notes are provided by site admins on a best effort base as a contribution to the IGI communities and MUST not be considered as a subsitute of the Official IGI documentation.
  • This document is addressed to site administrators responsible for middleware installation and configuration.
  • The goal of this page is to provide some hints and examples on how to install and configure an IGI Site-BDII based on EMI-2 middleware.

Service installation

O.S. and Repos

  • Starts from a fresh installation of Scientific Linux 6.x (x86_64). 
# cat /etc/redhat-release 
Scientific Linux release 6.2 (Carbon)

* Install the additional repositories: EPEL, Certification Authority, EMI-2 

# yum install yum-priorities yum-protectbase epel-release
# rpm -ivh http://emisoft.web.cern.ch/emisoft/dist/EMI/2/sl6/x86_64/base/emi-release-2.0.0-1.sl6.noarch.rpm

# cd /etc/yum.repos.d/
# wget http://repo-pd.italiangrid.it/mrepo/repos/egi-trustanchors.repo

  • Be sure that SELINUX is disabled (or permissive). Details on how to disable SELINUX are here: 

# getenforce

Service configuration

You have to copy the configuration files in another path, for example root, and set them properly (see later): 
# cp -r /opt/glite/yaim/examples/siteinfo/* .
