DataStax Opscenter代理未连接：“无法找到cassandra.yaml配置文件” [英] DataStax Opscenter Agent doesn't connect: "Unable to locate cassandra.yaml configuration file"

问题描述

我在Windows Server 2012 R2 Datacenter计算机上安装了Datastax Community Edition v2.0.3。
安装完成后，我无法使用OpsCenter连接到数据库，因为代理无法启动：它在页面顶部显示0 of 1 agents connected。我可以使用CQLSH连接到数据库本身。 v2.0.2不会出现此问题。

我的 datastax_opscenter_agent-stderr.log 文件包含以下内容： / p>

  2013-12-05 16:16:54 Commons Daemon procrun stderr initialized

实际上有一个目录下的 C：\ Program Files \DataStax Community \apache-cassandra\conf 目录中的cassandra.yaml 成为。上面的消息说，它看起来 C：\\Program Files\\DataStax社区\\apache-cassandra\\\\\\卡.yaml ，尽管（注意\bin）。

在 opscenter\conf \clusters\local中设置 conf_location .conf 根据日志的建议，导致相同的错误。

Windows防火墙已关闭所有这一切。 p>

编辑

我一直在修补一点，除了其中正在查找 cassanda.yaml 的路径已从

中更改的路径，日志中有相同的异常。

'C ：\Program Files\DataStax Community\apache-cassandra\bin\conf\cassandra.yaml'

到

'C：\Program Files\DataStax Community\utils\conf\cassandra.yaml'

我不知道

我已经尝试将 cassandra.yaml 复制到上面的目录中。这会消除 datastax_opscenter_agent-stderr.log 中的异常，但OpsCenter仍然显示连接的1个代理中的0个。但是，仪表板现在显示图表中的数据。我也可以添加一个键空间到模式，但它不会显示，当我创建它。但是它可以使用 CLQSH 访问。显然在两个不同的地方有 cassandra.yaml 不是理想的。

解决方案

我通过设置conf_location属性来修复这个问题：

  conf_location = C：\Program Files\DataStax Community\apache-cassandra\conf\cassandra.yaml 
  

最初，我在路径中使用引号，但没有工作。删除引号是个诡计。

I have installed Datastax Community Edition v2.0.3 on a Windows Server 2012 R2 Datacenter machine. After a vanilla install, I can't connect to the database with OpsCenter because the agent failed to start: it says "0 of 1 agents connected" in the top of the page. I can connect to the database itself using CQLSH. This problem does not occur with v2.0.2.

My datastax_opscenter_agent-stderr.log file contains the following:

2013-12-05 16:16:54 Commons Daemon procrun stderr initialized
Exception in thread "Initialization" clojure.lang.ExceptionInfo: throw+: {:type :bad-permissions, :message "Unable to locate the cassandra.yaml configuration file.

There is in fact a cassandra.yamlfile in the C:\Program Files\DataStax Community\apache-cassandra\conf directory, where it is supposed to be. The message above states that it looked in C:\\Program Files\\DataStax Community\\apache-cassandra\\bin\\conf\\cassandra.yaml, though (notice the \bin).

Setting the conf_location option in the opscenter\conf\clusters\local.conf, as per the log's suggestion, results in the same error.

The Windows Firewall has been turned off through all this.

Edit

I've been tinkering a little bit, and now I get the same exception in the log, except the path where it's been looking for cassanda.yaml has changed from

'C:\Program Files\DataStax Community\apache-cassandra\bin\conf\cassandra.yaml'

to

'C:\Program Files\DataStax Community\utils\conf\cassandra.yaml'

I have no idea what I did to change this.

I have tried copying cassandra.yaml to the directory above. This gets rid of the exception in datastax_opscenter_agent-stderr.log, but OpsCenter still says "0 of 1 agents connected". However, the Dashboard is now showing data in the graphs. I am also able to add a keyspace to the schema, but it won't show up after I created it. It is accessible using CLQSH, though. Obviously having cassandra.yaml in two different places is not ideal, either.

解决方案

I fixed this problem by setting the conf_location property as below:

conf_location = C:\Program Files\DataStax Community\apache-cassandra\conf\cassandra.yaml

Initially I was using quotes around the path, which didn't work. Removing the quotes did the trick.
