我想爲我正在構建的應用程序使用ElasticSearch,並且我將它託管在Rackspace服務器上。但是,auto-discovery
功能不起作用。我認爲這是因爲auto-discovery
使用廣播和多播來查找具有匹配羣集名稱的其他節點。我發現這個article表示Rackspace現在支持多點傳送和廣播,並具有新的雲網絡功能。然後按照文章的說明創建了一個網絡,並將該網絡添加到運行節點的兩臺服務器上。然後我試圖重新啓動兩個節點上ElasticSearch
,但他們並沒有找到對方,每個自稱爲「主」(這裏是從日誌輸出):elasticsearch自動發現機架空間不工作

添加網絡是否不夠(Rackspace也給了我這個網絡的IP)?我需要以某種方式在conf文件中指定在使用多播來查找其他節點時檢查該網絡嗎?
我也發現這個提供了不同方法的article。按照文章的說明,我把這個變成/config/elasticsearch.yml
:
cloud:
account: account #
key: account key
compute:
type: rackspace
discovery:
type: cloud
然而,然後當我試圖重新啓動ElasticSearch
我得到這個:
Stopping ElasticSearch...
Stopped ElasticSearch.
Starting ElasticSearch...
Waiting for ElasticSearch.......
WARNING: ElasticSearch may have failed to start.
而且它也無法啓動。我檢查到的任何錯誤日誌文件,但是這是所有在那裏:

[2013-04-03 22:31:00,797][INFO ][plugins ] [Chamber] loaded [], sites []
它停在那裏沒有任何錯誤和不持續的。
有沒有人成功獲得ElasticSearch
才能在Rackspace雲中工作?我知道單播選項也可用,但我寧願不必單獨指定每個IP地址,因爲我希望以後可以輕鬆添加其他節點。謝謝!
UPDATE
我還沒有解決的問題還沒有,但經過一番搜索,我發現這個post,上面寫着「老字號」雲插件被中斷,並只是一個Ec2插件取代了亞馬遜的雲,這解釋了爲什麼我對配置文件所做的更改不起作用。
愚蠢的問題,但是你可以用更明確的單播發現? – mconlin 2014-04-03 01:34:47
