Question

我正在尝试使用Apache Ambari创建一个节点集群。在这些步骤中，在步骤3中，我们需要使用FQDN（完全限定域名）提供要添加到群集的主机列表

要获取FQDN，我使用了

Registering with the Server.....
Registration with the Server Failed

Ubuntu终端的命令。结果为sridhar25

在群集创建期间，我的FQDN为sridhar25 [1]：http://i.stack.imgur.com/2IYCq.png

但选择Next后，我的注册失败。

我的日志文件显示

$ hostname -f
sridhar25.sridhar.com

即使我尝试将FQDN更改为

list_com_and_url = []
with open('my_file') as f:
    for line in f:
        name, url = line, next(f)
        list_com_and_url.append(zip(name, url))

我收到相同的错误

如何在Ambari-Cluster中注册主机？

Answer 1

这很可能是DNS问题。您是否已将所有节点的条目添加到每个节点上的/ etc / hosts文件中？

在每个节点上运行以下命令以分别获取正确的FQDN和IP。

hostname -f
ifconfig

获得这些值后，需要将它们添加到每个主机上的/ etc / hosts文件中。

例如，如果您只有两个节点并且获得了值：

sridhar25:
sridhar25.sridhar.com
192.168.1.12

sridhar26:
sridhar26.sridhar.com
192.168.1.13

然后，您需要将以下两行添加到每个/ etc / hosts文件中：

192.168.1.12 sridhar25.sridhar.com
192.168.1.13 sridhar26.sridhar.com
