python - centos 5 中的 Ambari 2.0 安装

Question

我计划在 CentOS 5 中用一个节点设置 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 管理服务器 UI 在另一个盒子中自动安装 Ambari 代理。我有一个与我的其他服务器的无密码 SSH，它工作正常，但在尝试向其他节点注册时遇到以下错误。谁能帮忙解决一下？

看起来您在该主机上安装的 ambari-agent 无效，原因是错误:No such file or directory: '/var/lib/ambari-agent/data/version'我会卸载并重新安装它:

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

然后再次尝试安装。
