How to set up an DPM nameserver with a postgres backend ======================================================= The DPM nameserver (DPNS) is run by the dpmmgr user. This user requires a copy of the host certificate files: cp -p /etc/grid-security/hostcert.pem /etc/grid-security/dpmmgr/dpmcert.pem cp -p /etc/grid-security/hostkey.pem /etc/grid-security/dpmmgr/dpmkey.pem chown dpmmgr:dpmmgr /etc/grid-security/dpmmgr/dpm* Create a postgres database user for the DPNS server: createuser -P The command above will prompt you for a password for the new user. Create the DPNS database: createdb -O Create the DPNS database tables: psql -W -U -f /usr/share/lcgdm/create_dpns_tables_postgres.sql Let the DPNS server know about the account information and make sure only the dpmmgr user can read this information: touch /etc/DPNSCONFIG chmod 600 /etc/DPNSCONFIG chown dpmmgr:dpmmgr /etc/DPNSCONFIG echo /@/ > /etc/DPNSCONFIG If the / part is omitted the database "cns_db" will be used. If you have a firewall, open the DPNS server port (5010). Once the configuration is completed, change RUN_DPNSDAEMON=no to RUN_DPNSDAEMON=yes in /etc/default/dpnsdaemon, then start the DPNS server: invoke-rc.d dpnsdaemon start
