The EPIKH Project (Exchange Programme to advance e-Infrastructure Know-How) Elisa Ingrà Consortium GARR- Roma WMS LB BDII Installation and Configuration

The instructions provided in this presentation assume that you are going to use a machine with Scientific Linux 5.4 installed. –Virtual Machine image (GILDA VM Base_SLC4._i386) available at: Preliminaries

ssh XX = 01, 02, 03, ….., 23 Password: GildaVM.10

4 Repository settings Specify the mrepo host: export MREPO= Configure the repository as follows: REPOS="dag ig glite-generic lcg-ca jpackage glite-bdii glite-wms" Get repositories with: for name in $REPOS; do wget $MREPO/$name.repo -O /etc/yum.repos.d/$name.repo; done Copy the gilda utils: wget -O /etc/yum.repos.d/gilda.repo

5 System requirements Please check: –If you have a valid hostname –To verify, type: hostname -f –To edit the hostname: Install ntp yum install ntp  vim /etc/hosts  vim /etc/hostname  vim /etc/sysconfig/network  hostname  vim /etc/hosts  vim /etc/hostname  vim /etc/sysconfig/network  hostname

Modify the ig.repo as following: 6 ig Repo # # INFNGRID repositories # [ig_sl4_i386] name = INFNGRID 3.1 i386 baseurl = i386/RPMS.3_1_0/ enabled = 1 protect = 0 [ig_sl4_i386_externals] name = INFNGRID 3.1 i386 (externals) baseurl = i386/RPMS.3_1_0_externals/ enabled = 0 protect = 0

Modify the glite-generic.repo as following: 7 # # gLite generic repositories # [glite-generic_sl4_i386_release] name = gLite generic 3.1 i386 (release) baseurl = enabled = 1 protect = 0 [glite-generic_sl4_i386_updates] name = gLite generic 3.1 i386 (updates) baseurl = enabled = 0 protect = 0 [glite-generic_sl4_i386_externals] name = gLite generic 3.1 i386 (externals) baseurl = enabled = 1 protect = 0

Then update your host: yum clean all Install CAs on ALL profiles: yum install -y lcg-CA Ig: yum install ig-yaim Gilda utils: yum install gilda_utils 8 YUM install

BDII install: yum install ig_BDII WMS install: yum install ig_WMS 9 YUM install
