Linux中使用hostname命令修改主机名称（非常简单）_LINUX_操作系统_

Usage: hostname [-v] {hostname|-F file} set hostname (from file)
domainname [-v] {nisdomain|-F file} set NIS domainname (from file)
hostname [-v] [-d|-f|-s|-a|-i|-y|-n] display formatted name
hostname [-v] display hostname

hostname -V|–version|-h|–help print info and exit

dnsdomainname=hostname -d, {yp,nis,}domainname=hostname -y

-s, –short short host name
-a, –alias alias names
-i, –ip-address addresses for the hostname
-f, –fqdn, –long long host name (FQDN)
-d, –domain DNS domain name
-y, –yp, –nis NIS/YP domainname
-F, –file read hostname or NIS domainname from given file

This command can read or set the hostname or the NIS domainname. You can
also read the DNS domain or the FQDN (fully qualified domain name).
Unless you are using bind or NIS for host lookups you can change the
FQDN (Fully Qualified Domain Name) and the DNS domain name (which is
part of the FQDN) in the /etc/hosts file.
