(2) Modify the machine DNS setting: Modify /etc/resolv.conf file Nameserver 34.0.188.99 # Set this machine's DNS to 34.0.188.99
(3) Modify the host name: a, open / etc / hosts file Add below 34.0.188.99 Linux.zzw.com Linux b, modify / etc / sysconfig / network file hostname = Linux.zzw.com === ============================================================================================================================================================================================================= ================

(4) Named.ca, localhost.zone, Named.local These three files basically do not change
(5) Modify the / etc / hosts file: Implement the mapping of other major computers on the Internet, which is usually as a backup of DNS, that is, the HOSTS table is used when the DNS system occurs. Example: 127.0.0.1 Localhost localhost.localdomain localhost 34.0.188.99 Linux.zzw.com Linux // Since each server will have several domain names and IP correspondence is permanent, the Hosts table should be stored.
(6) Modify the /etc/resolv.conf file: Specify the IP and search order of the domain name server. Example: Domain zzw.com // Defines the local domain name. Search zzw.com/A Simplifies the host name entered by the user, that is, when the user enters THJ, make DNS to successfully resolve it to Linux.zzw.com. It is mutually exclusive with Domain, no matter who appears is used to define the search list. * / Nameserver 192.168.10.1 // Defines the IP of the domain name server, up to three, it is recommended to use two.
(7) Modify the /etc/hosts.conf file: How to implement the relationship between the HOSTS table and DNS. Example: Order hosts, bind // Analyze the order of domain name Multi ON / / Allow a computer to have multiple IP
