【问题描述】：

我已经按照http://docs.openstack.org/developer/swift/development_saio.html 上的说明在机器 1 (Centos 6) 上安装了 OpenStack Swift 服务。

我可以在同一环境中使用 curl 检索令牌。

curl -v -H 'X-Storage-User: test:tester' -H 'X-Storage-Pass: testing' http://machine-1IP:8099/auth/v1.0

* About to connect() to machine-1 ip port 8099 (#0)
*   Trying machine-1ip... connected
* Connected to machine-1 port 8099 (#0)

> Host: machine-1IP:8099
> Accept: */*
> X-Storage-User: test:tester
> X-Storage-Pass: testing

如果我尝试从另一台机器（机器 2）访问它。我得到主机不可访问异常。我可以从 machine-2 ping machine-1。

curl -v -H 'X-Storage-User: test:tester' -H 'X-Storage-Pass: testing' http://machine-1IP:port/auth/v1.0

请说明为什么无法从远程机器访问 Swift REST 服务？我是否遗漏了配置中的任何内容？

【问题讨论】：

当请求被定向到“machine-1IP”时，您的外部机器 resolv.conf 是否知道它应该映射到的 IP 地址

【解决方案1】：

Host unreachable 表示机器 2 无法访问机器 1。它与 Openstack/Swift 无关。检查您的路由器设置和/etc/hosts。

* Could not resolve host: testing'
* Failed connect to machine-1IP:8099; Host unreachable
