Change the DNS parsing Order of Linux (DNS to hosts)

In Linux, often parsing a domain name, the first will find /etc/hosts file, if the /etc/hosts file does not correspond, will go to find DNS, then what is the way to let the host first look for DNS it?

Of course, it's defined in the /etc/nsswitch.conf file.

/etc/nsswitch.conf

Hosts:files DNS//Find this section and change it to the following

Hosts:dns files

In this way, your host will go to the DNSFirst, and then go to the hosts

Note: The file content is not necessarily so simple, but the principle is similar.
