我刚安装完 Centos 后,无法好吃,获得或者卷曲工作。我得到的是:
$ curl http://www.google.com
curl: (6) Couldn't resolve host 'www.google.com
最令人惊讶的是 ping 确实似乎有效。
ping www.google.com
第一反应,检查 iptables:我根本没有规则。正如我所说,全新安装。
/etc/resolv.conf
nameserver 127.0.0.1
nameserver 8.8.8.8
nameserver 8.8.4.4
PS:尝试了使用 http:// 和不使用 http:// 两种方式。

它至少应该开始工作。
接下来修复你的本地解析器
