In ubuntu, you can simply build a DNS server in ubuntu to understand how DNS works. 1. install the corresponding server software. Apt-get install bind9 install bind9 2 and set the primary server domain and domain parsing file vim/etc/bind/named. conf. local then sets the domain zone and the domain resolution file zone "linux31.com" {type master; file "db.linux31.com" ;}; www.2cto.com 3, according to the bind9 built-in template db. local modifies the content of the domain resolution file. Generally, the default storage location of the domain resolution file is/etc/var/cache/bind. we will set/ect/bind/db. copy local data to/etc/var/cache/bind and change it to db. linux31.comcp/etc/bind/db. local/var/cache/bind/db.linux31.com and then modify the template db. local content; BIND data file for local loop Back interface; $ TTL 604800 @ in soa localhost. root. localhost. (2; Serial 604800; Refresh 86400; Retry 2419200; Expire 604800); Negative Cache TTL; @ in ns localhost. @ in a 127.0.0.1 @ in aaaa: 1 ~ ~ Www.2cto.com. Generally, you don't need to modify the above content. you just need to fill in the address of your dns server (that is, the local address) below and it will be OK; BIND data file for local loopback interface; $ TTL 604800 @ in soa localhost. root. localhost. (2; Serial 604800; Refresh 86400; Retry 2419200; Expire 604800); Negative Cache TTL; @ in ns localhost. @ in a 127.0.0.1 @ in aaaa: 1 @ in a 192.168.1.116 ~ Then, save and exit, and restart bind service/etc/init. d/bind9 restart www.2cto.com 4, and then check whether DNS works. Modify the DNS option in/etc/resolv. conf on another server and set the DNS server address to 192.168.1.106 (I configured the DNS IP address). This process is easy to forget. Then, ping linux31.com on another host to check whether the host can be pinged.
