Question

我遇到了远程命令行无法解析本地主机名的问题。它不会显示为user@localhost，user@ip或任何变体，而是显示为user@(none)：

Using username "rogue".
rogue@<my-ip>'s password:
Linux (none) 3.13.7-x86_64-linode38 #1 SMP Tue Mar 25 12:59:48 EDT 2014 x86_64

rogue@(none):~$

任何进行中的命令都会导致出现此警告消息：

rogue@(none):~$ sudo service nginx start
sudo: unable to resolve host (none)
[sudo] password for rogue:

查看我的主机和主机名文件，我没有看到任何异常：

的/ etc /主机名

127.0.0.1 localhost
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

的/ etc /主机

127.0.0.1       localhost
127.0.1.1       debian

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

我的网络配置可能出现什么问题？如果可能，我希望它显示为user@my.domain，但我需要localhost才能正确路由到127.0.0.1

您的/etc/hostname非常错误。它应该是FQDN的纯文本，例如 example.com 或 localhost ，而不是{的类似副本{1}}

您可能希望使用命令/etc/hosts来查看和设置主机名，hostname
