DNS service configuration and application 4

DNS service configuration and application 4-Linux Enterprise Application-Linux server application information. The following is a detailed description. 23. configure the secondary name server: the secondary name server can also provide the domain name resolution function to the client. However, unlike the primary name server, its data is not directly input, the data is copied from other servers (Primary name servers or other secondary name servers), but only copies. Therefore, the data in the secondary name server cannot be modified. Its main configuration file is also/etc/named. conf. The example is as follows:
Directory "/var/named ";
Dump-file "/var/named/data/cache_dump.db"
Statistics-file "/var/named/data/named_stats.txt"
Version "4.9.11"
Zone "."{
Type hint;
File "named. ca"
};
Zone "jackie.com" {# sets the Slave region. The name of this region must be the same as that of the master region of the Master name server.
Type slave; # define the dns region type
File "slaves/jackie.com. zone" # Set the name of the file in the primary region
Master {192.168.17.177 ;}; # Set the IP address of the master name server
};
Zone "16.168.192.in-add-arpa" {# Set the response resolution Area
Type slave;
File "slaves/192.168.16.arpa"
Master {192.168.17.177 ;};
};
24. Configure Cache-only server: equivalent to the dns forwarding server in win
The configuration is as follows:
Iptions {
Directory "/var/named ";
Dump-file "/var/named/data/cache_dump.db"
Statistics-file "/var/named/data/named_stats.txt"
Version "4.9.11"
Forward only; # Set the forwarding Method
Forwarders {
61.144.56.101; # Set the dns servers to which the server is forwarded.
202.96.128.68;
};
};
Include "/etc/rndc. key ";
25./etc/init. d/named start # start the dns Service
/Etc/init. d/named stop # disable dns Service
/Etc/init. d/named restart # restart the dns Service
Run ntsysv # set to automatically start dns
26. dns Client Configuration
Linux: directly modify/etc/resolve. conf
Windows: select the preferred and backup dns Service For nic attribute settings.
