ubuntu安装以后缺省的hostname是ubuntu,安装的机器多了,容易产生混淆,直接用命令#hostname newname,重启后失效。
修改/etc/hostname文件就可以了,
root@ubuntuServer:/etc# more hostname
#ubuntu
newname
但是这样一来在X下面,很多命令不正常,比如打开terminal出不来,原来还需要修改
/etc/hosts文件,
127.0.0.1 localhost.localdomain localhost newname
#
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
