From the setup of the DNS serverThe previous article has a schema procedure that says "Primary DNS server", and now, from the server's schema step, the IP address and server name of the master-slave DNS server are unchanged.Basically, the settings from the server are simple, because the master server's data has been done, from the server only need to do a good link, and then verify that the data can be read from the primary server.The ip:172.16.100.1 of the primary server, called DNS, is ip:172.

1. Clear DNS cache in Linux There are two methods to implement DNS caching in Linux:One is to use DNS CacheProgramNscd (Name Service cache Daemon) is responsible for managing DNS cache.One way to implement DNS caching is to use bind to set up the caching name server. To clear the cache on nscd, restart the nscd service to clear the DNS cache. Run the following command:# Service nscd restartOr#/Etc/init. d/nscd restart To clear the cache on the BIND server, run the following command:#
