Notes about Installation and Configuration of a Site BDII - WORK IN PROGRESS

  • 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/UMD middleware.

Service installation

O.S. and Repos

  • Starts from a fresh installation of Scientific Linux 5.x (x86_64).
# cat /etc/redhat-release 
Scientific Linux SL release 5.7 (Boron) 

* Install the additional repositories: EPEL, Certification Authority, UMD

# yum install yum-priorities yum-protectbase
# cd /etc/yum.repos.d/
# rpm -ivh http://mirror.switch.ch/ftp/mirror/epel//5/x86_64/epel-release-5-4.noarch.rpm
# wget http://repo-pd.italiangrid.it/mrepo/repos/egi-trustanchors.repo
# rpm -ivh http://repo-pd.italiangrid.it/mrepo/EMI/1/sl5/x86_64/updates/emi-release-1.0.1-1.sl5.noarch.rpm
# wget http://repo-pd.italiangrid.it/mrepo/repos/igi/sl5/x86_64/igi-emi.repo

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

# getenforce 
Disabled

  • Check the repos list (sl-*.repo are the repos of the O.S. and they should be present by default).

# ls /etc/yum.repos.d/
egi-trustanchors.repo  
emi1-third-party.repo emi1-base.repo emi1-updates.repo
igi-emi.repo
epel.repo epel-testing.repo  
sl-contrib.repo sl-fastbugs.repo sl-security.repo sl-testing.repo sl-debuginfo.repo sl.repo sl-srpms.repo
IMPORTANT: remove the dag repository if present

yum install

# yum clean all
Loaded plugins: downloadonly, kernel-module, priorities, protect-packages, protectbase, security, verify, versionlock
Cleaning up Everything

# yum install ca-policy-egi-core
# yum install emi-bdii-site

see here for details

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/* .
