Ubuntu Configuration DNS

As we all know, the CentOS configuration DNS is very simple, modify the next/etc/resolv.conf, you can take effect. But in Ubuntu, the resolv.conf file indicates that the write will be overwritten and cannot be written here.

Method One:

Modify/etc/network/interfaces (interfaces file is omnipotent, can be equipped with IP, routing, DNS)

Dns-nameservers 114.114.114.114

Method Two:

Modify the/etc/resolvconf/resolv.conf.d/base file, the file is empty by default. (or create a new tail file to write to nameserver)

NameServer 114.114.114.114

NameServer 8.8.8.8 Save after modification and execute sudo resolvconf-u to make it effective immediately.

Then you will find a few more lines in the/etc/resolv.conf file, NameServer 114.114.114.114 is automatically written by the RESOLV program.

Method Three:

Modify/etc/resolv.conf (will expire after restarting the network)
