Install the IIS service in the win10 virtual machine:

Put the written web page in the following path: C:\ inetpub\ wwwroot also turn off the firewall function to install the DNS service: [root@nginx conf] # yum install bind-ywin10 and win7 change the network DNS address to 192.168.18.136 [root@nginx conf] # vim / etc/named.confoptions {listen-on port 53 {any;}; / / change the parentheses to any listen-on-v6 port 53 {:: 1;} Directory "/ var/named"; dump-file "/ var/named/data/cache_dump.db"; statistics-file "/ var/named/data/named_stats.txt"; memstatistics-file "/ var/named/data/named_mem_stats.txt"; recursing-file "/ var/named/data/named.recursing"; secroots-file "/ var/named/data/named.secroots" Allow-query {any;}; / / change the localhost in parentheses to any//, press Esc to exit the insertion mode after modification, and enter: wq save exit [root@nginx conf] # vim / etc/named.rfc1912.zoneszone "kgc.com" IN {type master; file "kgc.com.zone"; allow-update {none;};} / / add the above, press Esc to exit the insertion mode after modification, and enter: wq save exit [root@nginx conf] # cd / var/named/ [root@nginx named] # cp-p named.localhost kgc.com.zone [root@nginx named] # vim kgc.com.zone$TTL 1D @ IN SOA @ rname.invalid.

We use win7 to visit: www.kgc.com to get a normal Nginx welcome interface:

At this point to the success of the hotlink! The next thing we need to do is do hotlink protection in Nginx!

At this time, the anti-theft chain is a great success!
