Voms gLite 3.2 Upgrade Guide

Install a VOMS mysql SL5 node

The general steps for installing the OS and the gLite-VOMS mysql server are explained here.

For VOMS mysql install only the rpms without launching yaim configuration

Migrating the database to the new node

To migrate the VO database to the new node you need to perform the following steps, for each VO DB:
  • Dump the old database on the old VOMS server and transfer the file to the new node
      mysqldump -h <OLD_HOSTNAME> -u <PRIV_USER> -p <PWD> --databases <DB_NAME> > <DUMP_FILE>
  • Use the database dump on the new machine to create the new database
    mysql -h <NEW_HOSTNAME> -u <PRIV_USER> -p <PWD> < <DUMP_FILE>
  • Grant ALL PRIVILEGES to the user that VOMS-ADMIN will use to connect to and use the database
     mysql -h <NEW_HOSTNAME> -u <PRIV_USER> -p <PWD>
                  TO <VOMS_USER>@localhost
  • synchronize voms configuration files from the old machine with the yaim configuration files on the new one, i.e. make sure username and password for the VO databases are the same. In particular:
    • the configuration files on the old machine using python scripts can be found in /opt/glite/etc/config:
      /opt/glite/etc/config/glite-voms-server.cfg.xml ---> for username and password of mysql admin
      /opt/glite/etc/config/vo-list.cfg.xml --> for username and password of each VO database
    • yaim configuration files on the new machine can be found in siteinfo/site-info.def and services/glite-voms
  • launch yaim configuration after setting yaim variable VOMS_DB_DEPLOY to 'false' in the site-info.def or the siteinfo/services/glite-voms file
    /opt/glite/yaim/bin/yaim  -c -s site-info.def -n VOMS
  • re-start tomcat
  • launch upgrade VO, for each VO as:
    voms-admin-configure upgrade --vo  <VO name>
  • re-start voms server and voms admin with
    /opt/glite/etc/init.d/voms and /opt/glite/etc/init.d/voms-admin
  • register the VOMS host identity as a default admin:
    /opt/glite/sbin/voms-db-deploy.py add-admin --vo <VO name> --cert /etc/grid-security/hostcert.pem
