How to set up an LFC server with a mysql 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 the LFC database on the mysql server: mysql -u root < /usr/share/lfc/create_lfc_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 LFC 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 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-mysql start If you want to start the service automatically at boot time: chkconfig --add lfc-mysql
