A slave name server doesn’t need to retrieve all of its database (db) files over the network because these db files “db.127.0.0” and “db.cache” are the same as on a primary master, so you can keep a local copy of these files on the slave name server. Copy the “db.127.0.0” file from master name server to slave name server. Copy the “db.cache” file from master name server to slave name server. Configuration of the “/etc/rc.d/init.d/named” script file for all type of name server Configure your “/etc/rc.d/init.d/named” script file to start and stop BIND/DNS daemons Server. This configuration script file can by used for all type of name server (caching, master or slave). Create the named script file (touch /etc/rc.d/init.d/named) and add: #!/bin/sh # # named           This shell script takes care of starting and stopping #                 named (BIND DNS server). # # chkconfig: - 55 45 # description: named (BIND) is a Domain Name Server (DNS) \ # that is used to resolve host names to IP addresses. # probe: true # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up.
