我打算用一个节点在 CentOS 5 中设置 Ambari 2.0。我成功地在一个盒子中设置了 Ambari 服务器，并尝试通过 Ambari admin Server UI 在另一个盒子中自动安装 Ambari 代理。我的其他服务器有一个无密码 SSH，它工作正常，但是在尝试向其他节点注册时遇到以下错误。有人可以帮忙解决吗？

由于错误，您似乎在该主机上安装了无效的 ambari-agent：No such file or directory: '/var/lib/ambari-agent/data/version'我将卸载并重新安装它：

sudo yum erase ambari-agent
sudo yum install ambari-agent

然后再次尝试安装。
