curl 无法连接到本地主机端口 80 [英] curl Failed to connect to localhost port 80

问题描述

我的主机文件将 127.0.0.1 映射到 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

在我的主机文件中我有

127.0.0.1   localhost

curl 命令似乎无法识别 /etc/hosts 中的条目.有人能解释一下原因吗?

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

更新:我还没有尝试过，但我发现你可以配置 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，似乎 curl 正在尝试使用 IPv6 进行联系您的本地网络服务器.

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 Web 服务器未侦听 IPv6，因此连接失败.

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

您可以尝试对 curl 使用 --ipv4 选项，这应该在两者都可用时强制进行 IPv4 连接.

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