How to set up an LFC server with a postgres backend
===================================================

The LFC server is run by the lfcmgr user. This user requires a copy of
the host certificate files:

  cp -p /etc/grid-security/hostcert.pem /etc/grid-security/lfcmgr/lfccert.pem
  cp -p /etc/grid-security/hostkey.pem /etc/grid-security/lfcmgr/lfckey.pem
  chown lfcmgr:lfcmgr /etc/grid-security/lfcmgr/lfc*

Create a postgres database user for the LFC server:

  createuser -P <user>

The command above will prompt you for a password for the new user.

Create the LFC database:

  createdb -O <user> <dbname>

Create the LFC database tables:

  psql -W -U <user> <dbname> -f /usr/share/lfc/create_lfc_tables_postgres.sql

Let the LFC server know about the account information and make sure
only the lfcmgr user can read this information:

  touch /etc/NSCONFIG
  chmod 600 /etc/NSCONFIG
  chown lfcmgr:lfcmgr /etc/NSCONFIG
  echo <user>/<password>@<dbserver>/<dbname> > /etc/NSCONFIG

If the /<dbname> part is omitted the database "cns_db" will be used.

If you have a firewall, open the LFC server port (5010).

Once the configuration is completed, start the LFC server:

  service lfc-postgres start

If you want to start the service automatically at boot time:

  chkconfig --add lfc-postgres
