Cygwin 连接已关闭：::1

在安装 Hadoop 期间，我尝试设置 CYGWIN 和ssh。已安装，ssh 也已成功启动，并按照说明设置授权密钥这里但是当我尝试使用ssh它连接到本地主机时显示..

经过很多谷歌搜索我试过了ssh -v cyg_server@localhost但它提示输入我不知道的密码。

有人能帮我与 localhost 建立成功且经过身份验证的 ssh 连接吗？无论是通过密码，还是创建另一个用户，或者跳过身份验证步骤。这对我来说太好了！谢谢。

答案1

以下是一些可以尝试的方法：

  1. 尝试替换127.0.0.1localhost。
  2. 验证 cyg_server 用户帐户是否具有有效的主目录（/home/cyg_server如果需要，请创建）并且其 shell 是/bin/bash。
  3. 彻底卸载 Cygwin，清理其目录和环境变量，然后重新安装。要使用的密码是您在配置 Cygwin 时提供的密码。
  4. 尝试使用您的普通帐户，而不是 Cygwin 安装建议的 cyg_server。

我不明白为什么您在使用 Cygwin 时您的帖子被标记为“linux”——在这种情况下应该是“windows”。在这种情况下，请查看这篇文章： 在 Windows 中运行 Hadoop。

答案2

cyg_server不供用户直接使用。

检查/etc/hosts文件是否正确，检查它是否明确将 localhost 解析为 127.0.0.1。

如果您不需要 IPv6，请将其停用。
