Linux hostname命令修改主机名称

Linux中使用 hostname命令修改主机名称。

在Linux中修改主机名的例子。

直接运行hostname可以查看目前的主机名称，要查看hostname的其它命令参数，运行hostname -h如下：
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.
