  • sudo 出现unable to resolve host 解决方法

    万次阅读 多人点赞 2012-11-30 08:50:16
    sudo: unable to resolve host abc 虽然sudo 还是可以正常执行, 但是警告讯息每次都出来,而这只是机器在反解上的问题, 所以就直接从/etc/hosts 设定, 让abc(hostname) 可以解回127.0.0.1 的IP 即可. /et

    Ubuntu环境, 假设这台机器名字叫abc(机器的hostname), 每次执行sudo 就出现这个警告讯息:
    sudo: unable to resolve host abc
    虽然sudo 还是可以正常执行, 但是警告讯息每次都出来,而这只是机器在反解上的问题, 所以就直接从/etc/hosts 设定, 让abc(hostname) 可以解回127.0.0.1 的IP 即可.

    /etc/hosts 原始内容

    127.0.0.1       localhost
    
    # The following lines are desirable for IPv6 capable hosts
    
    ::1     localhost ip6-localhost ip6-loopback ip6-loopback
    
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters
    
    ff02::3 ip6-allhosts 

    在127.0.0.1 localhost 后面加上主机名称(hostname) 即可, /etc/hosts 内容修改成如下:

    127.0.0.1       localhost abc  #要保证abc这个名字与 /etc/hostname中的主机名一致才有效
    
    # 或改成下面这两行
    #127.0.0.1       localhost
    #127.0.0.1       abc

    这样设完后, 使用sudo 就不会再有那个提示信息了。

  • Ubuntu修改host遇到unable to resolve host

        我本来要修改host的,就直接修改了/etc/hostname这个文件。但是我改了之后,在使用sudo命令时总会出现unable to resolve host这个错误,不过貌似并不影响sudo的正常使用。

        在网上查了一下,解决的方法是把/etc/hosts这个文件中127.0.1.1这一行中的名字也得改一下。我的理解是/etc/hostname这个文件的内容和/etc/hosts文件中127.0.1.1后面的名字应该一致。改了以后就没有unable to resolve host这个问题了。

    使用MAC终端联接远程的linux服务器,进入的时候显示的是bogon的机器名。看日志的时候,发现很多unable to resolve host bogon的错误。

    于是在百度上各种找,基本的方法是修改/etc/hosts文件,添加对应的机器名。不过并不是所有的都有效果,现做一下总结。

    需要在/etc/hosts文件中加入本地,和外网ip对应的hostname,如下


    确保修改好后,保存然后重启network service,再次用终端登录,会发现名称已经改过来了。

    还有一种比较特殊的情况,就是当你使用了chroot命令后,需要同步修改你要chroot后的目录下的/etc/hosts文件。

    比如你chroot 到了/opt/myfile下,这时要同步修改 /opt/myfile/etc/hosts文件。
