curl无法连接到localhost端口80 [英] curl Failed to connect to localhost port 80

问题描述

我的主机文件映射 127.0.0.1 到 localhost 。

My hosts file maps 127.0.0.1 to localhost.

$ curl -I 'localhost'
curl: (7) Failed to connect to localhost port 80: Connection refused

然后

$ curl -I 127.0.0.1
HTTP/1.1 200 OK
Server: nginx/1.2.4
Date: Wed, 09 Apr 2014 04:20:47 GMT
Content-Type: text/html
Content-Length: 612
Last-Modified: Tue, 23 Oct 2012 21:48:34 GMT
Connection: keep-alive
Accept-Ranges: bytes

在我的hosts文件中我有

In my hosts file I have

127.0.0.1   localhost

curl 命令无法识别 / etc / hosts 中的条目。有人可以解释为什么？

It appears that curl command fails to recognize entries in /etc/hosts. Can someone explain why?

更新：我还没有尝试这个，但我已经发现你可以配置 nginx响应ipv4和ipv6

update: i've yet to try this but i've discoved you can configure nginx to respond to ipv4 and ipv6

推荐答案

由于您的主机文件中有 :: 1 localhost 行，因此curl似乎尝试使用IPv6联系您的本地Web服务器。

Since you have a ::1 localhost line in your hosts file, it would seem that curl is attempting to use IPv6 to contact your local web server.

由于网络服务器未在IPv6上侦听，因此连接失败。

Since the web server is not listening on IPv6, the connection fails.

您可以尝试使用 - ipv4 选项 curl ，当两者都可用时，应强制IPv4连接。

You could try to use the --ipv4 option to curl, which should force an IPv4 connection when both are available.
