推荐答案

这个好像跟dns服务有关.查看/etc/resolv.conf的内容

This seems to be related with dns service. Check content of /etc/resolv.conf

在这个文件中你应该有类似

In this file you should have something like

nameserver xxx.yy.zz.www nameserver xxx.yy.zz.www

如果你没有任何以 nameserver 开头的行，你应该在那里添加一些.使用您的提供商提供给您的地址或使用一些公共地址，例如 Google dns 8.8.8.8.

If you don't have any lines beginning with nameserver, you should add some there. Use address your provider gave you or use some public, for example Google dns 8.8.8.8.

如果您在这里有一些条目，请尝试 ping 它们.如果他们没有响应，请在第一行添加 Google dns 服务器

If you have some entries here, try ping them. If they are not responding add Google dns server on the first line

nameserver 8.8.8.8

如果您使用 DHCP，服务器应该为您提供名称服务器列表，并且您的 resolv.conf 文件应该没问题.如果不是，请联系您的 DHCP 服务器管理员.

If you are using DHCP, server should provide you nameservers list and your resolv.conf file should be okay. If it is not, contact your DHCP server administrator.
