Before Starting

1. HOSTNAME: emitestbed15.cnaf.infn.it + emitestbed17.cnaf.infn.it
2. OS: SL5 X86_64 Installed + Network
3. No Host certificate required

Service Installation

1. Repositories ( see EMI basic configuration):
   1. egi-trustanchors.repo + emi1.repo + epel.repo
2. $> yum clean all
3. $> yum makecache
4. $> yum install lcg-CA
5. INSTALLING WN + TORQUE
   1. $> yum install emi-wn emi-torque-client
6. INSTALLING MPI
   1. $> yum install glite-mpi ---> Note that this will install both mpi-start and yaim plugin !
   2. $> yum install openmpi.x86_64 ---> Only openmpi flavor tested
   3. $> yum install openmpi-devel.x86_64
7. INSTALLING glexec
   1. $> yum install emi-glexec_wn

Service Configuration

1. PREPARING FOR YAIM CONFIGURATION:
   1. COPY YAIM FILES UNDER ROOT: $>cp -r /opt/glite/yaim/examples/siteinfo/ /root/siteinfo/
   2. TESTERS VO files: follow description at [[https://twiki.cern.ch/twiki/bin/view/EMI/TestBed] [VO TESTERS HOWTO section 3.5]], download the following files: groups.conf, users.conf + vo.d directory
   3. CONTENT of /root/siteinfo: exp_soft_dir (DIR created after configuration) + services (DIR) + site-info.def + wn-list.conf + groups.conf + users.conf + vo.d (DIR)
   4. Find below the settings for Inter-Component testing EMI Testbed. Of course you will need to adapt these values to your own site (hostnames of other servers (SE, BDII, ARGUS..) , passwd, etc. etc. )

Note :

1. YAIM variables set into /root/siteinfo/services/XXXfiles will overrid variables in siteinfo.def file with same name
2. some YAIM variables are set in the yaim defaults files: /opt/glite/yaim//defaults/XXXfiles

1. After all yaim files are OK run the following commands:
   1. $> /opt/glite/yaim/bin/yaim -v -s site-info.def -n MPI_WN -n WN -n TORQUE_client ---> -v option checks yaim have all needed variables for your configuration
   2. $> /opt/glite/yaim/bin/yaim -v -s siteinfo/site-info.def -n GLEXEC_wn
   3. $> /opt/glite/yaim/bin/yaim -c -s site-info.def -n MPI_WN -n WN -n TORQUE_client ---> -c option actually runs configuration
   4. $> /opt/glite/yaim/bin/yaim -c -s siteinfo/site-info.def -n GLEXEC_wn
2. If everything's OK yaim will end with (BTW yaim output is in /opt/glite/yaim/log/yaimlog file)

.....
  INFO: Configuration Complete.                                               [  OK  ]
  INFO: YAIM terminated succesfully.

Service Testing

1. Basic test on WN was done sending jobs to the CE->WN and checking they go DONE SUCCESS. This was tracked here EMI gLite Job Management Tests Page
