Debian命令行无法解析主机。

Question

我的远程命令行无法解决本地主机名的问题。它不显示为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):~$

任何程序命令都会导致此警告消息：

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

看着我的主机和主机名文件，我没有看到任何异常的东西：

/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

/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

我的网络配置可能有什么问题？如果可能的话，我希望它是user@my.domain，但我需要localhost仍然正确地路由到127.0.0.1

Answer 1

你的/etc/hostname是非常错误的。它应该是FQDN的纯文本，如example.com或localhost，而不是/etc/hosts的类似副本。

您可能希望使用命令hostname查看和设置主机名，man it

Answer 2

这些命令呢？

hostname here.yourhost.name
sudo sed -i "s|localhost|localhost $(hostname)|g" /etc/hosts

在/etc/host中在其他本地主机名旁边添加主机名
