修改主机名称

Hostname

Set the hostname to your liking (e.g. arch):

# echo myhostname > /etc/hostname

Add the same hostname to /etc/hosts:

# nano /etc/hosts

#
# /etc/hosts: static lookup table for host names
#

#<ip-address>	<hostname.domain.org>	<hostname>
127.0.0.1	localhost.localdomain	localhost	myhostname
::1		localhost.localdomain	localhost

# End of file
