How to set up an DPM nameserver with a mysql 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 the DPNS database on the mysql server: mysql -u root < /usr/share/dpm/create_dpns_tables_mysql.sql Select a username and password for this mysql database table. Replace <user> and <password> in the commands below with your choice, also replace <hostname> with the hostname of the DPNS server: mysql -u root mysql> use mysql mysql> grant all on cns_db.* to <user>@localhost identified by '<password>'; mysql> grant all on cns_db.* to <user>@<hostname> identified by '<password>'; mysql> quit 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 <user>/<password>@<dbserver>/<dbname> > /etc/DPNSCONFIG If the /<dbname> 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, start the DPNS server: service dpm-mysql-nameserver start If you want to start the service automatically at boot time: chkconfig --add dpm-mysql-nameserver
