Ubuntu的 – 公钥authentication

我有一个主从集群。 我正在设立cloudera经理。

在主设备上，我使用以下方法创build了一个无密码的密钥。

ssh-keygen -f id_rsa -t rsa -N '' eval `ssh-agent` ssh-add ~/.ssh/id_rsa 

然后我把钥匙放在所有的奴隶上。

  cat /tmp/id_rsa.pub >> /root/.ssh/authorized_keys 

从主人我可以ssh没有密码。 它工作很好。

• ESXi 4.1.0 build-260247closuresVM的最佳方式
• 反向代理SSH / HTTPS在同一端口（443）
• 通过SSH执行远程MySQL查询
• centos私钥和rootlogin
• 什么会导致SSH连接失败，当使用`ssh：// user @ hostname`forms，但成功与裸`user @ hostname`？

现在我需要一个公钥来进行身份validation。 关键是什么？ 那是id_rsa.pub？ 我必须进入一个浏览器的身份validation公钥的位置。 当我使用id_rsa.pub时，我得到了这个错误。 但是使用这个键可以让我在没有密码的情况下进入任何其他的从机。
