使用CCM與Opscenter和手動代理安裝

我使用CCM安裝了4個節點本地羣集（127.0.0.1-127.0.0.4）。使用CCM與Opscenter和手動代理安裝

ccm create -v 2.1.5 -n 4 gp

我試圖手動安裝代理以使用OpsCenter（5.2.3.2015121015）。我開始刪除JMX端口的OpsCenter，所以配置是

[jmx] 
username = 
password = 

[agents] 

[cassandra] 
username = 
seed_hosts = 127.0.0.1,127.0.0.2,127.0.0.3,127.0.0.4 
password = 
cql_port = 9042

我配置了所有四個代理。例如agent3配置

[Giampaolo]: ~/opscenter/> cat agent3/conf/address.yaml 
stomp_interface: "127.0.0.1" 

agent_rpc_interface: 127.0.0.3 
jmx_host: 127.0.0.3 
jmx_port: 7300

我開始在前臺的OpsCenter和我有這樣的錯誤。當我開始劑4我有這樣的錯誤：

我有點的事實，第一個日誌告訴我，代理被發現的4，困惑，而位後，我對控制檯的錯誤。

代理4日誌告訴我一開始說沒有任何錯誤（僅INFO嚴重性）：

一段時間後，但是：

我已經在這之後嘗試添加其他代理，但我得到了奇怪的結果。類似於兩個代理的東西會轉到同一個C *節點，所以我在停止嘗試之前就認爲這個錯誤會導致其他錯誤。

問題：

什麼是錯誤的OpsCenter是日誌？
它是否與代理日誌上的錯誤有關？
我是否缺少配置（需要更多詳細信息？）
爲什麼OpsCenter抱怨缺少cassandra.yaml文件？不應該在任何主機上部署，即使它沒有本地C *安裝？

在此先感謝

編輯我增加了一些額外的信息：

[Giampaolo]: ~/> netstat -an | grep 7400 
tcp4  0  0 127.0.0.1.7400   *.*     LISTEN

應該127.0.0.4？

這對於節點4（的部分）的配置：

[Giampaolo]: ~/.ccm/gp/node4/conf/> cat cassandra.yaml | grep 127 
listen_address: 127.0.0.4 
rpc_address: 127.0.0.4 
    - seeds: 127.0.0.1,127.0.0.2,127.0.0.3,127.0.0.4

，這是address.yaml對於節點4：

[Giampaolo]: ~/opscenter/agent4/conf/> cat address.yaml 
stomp_interface: "127.0.0.1" 

agent_rpc_interface: 127.0.0.4 
jmx_host: 127.0.0.4 
jmx_port: 7400 

alias: "the4node"

OpsCenter中建議使用卡桑德拉密鑰空間來存儲所有的變量，所以它需要一個C *安裝。 – LHWizard

實際上，它會在使用CCM創建的集羣的第一個節點上創建一個新的密鑰空間。它需要另外安裝嗎？ – giampaolo

代理從jmx收集cassandra.yaml的位置。它也使用它來獲取要連接的廣播地址。我認爲如果jmx失敗，你會期望所有這些錯誤。您可以驗證node4的jmx連接是否正在使用netstat -anp |進行監聽grep 7400'''？它應該顯示一個127.0.0.4。也只是爲了仔細檢查，你可以發佈node4的address.yaml？ –

的配置是確定的，除了一個小細節。對於每一個代理，在address.yaml文件，localhost必須使用的，而不是在127.0.0.1參數jmx_host作爲cassandra user mailing list
