我正在尝试将ElasticSearch用于我正在构建的应用程序,而我正在Rackspace服务器上托管它。但是,auto-discovery
功能无效。我认为这是因为auto-discovery
使用广播和多播来查找具有匹配群集名称的其他节点。我发现这个article说Rackspace现在支持使用新的云网络功能进行多播和广播。然后按照文章的说明创建了一个网络,并将该网络添加到运行节点的两台服务器上。然后我尝试在两个节点上重新启动ElasticSearch
,但是他们没有找到对方,并且每个都声明自己为“主”(这里是日志的输出):

添加网络是否足够(Rackspace还为我提供了此网络的IP)?我是否需要在conf文件中指定在使用多播查找其他节点时检查该网络?
我还发现这个article提供了不同的方法。根据文章的说明,我将其放入/config/elasticsearch.yml
:
cloud:
account: account #
key: account key
compute:
type: rackspace
discovery:
type: cloud
然而,当我尝试重启ElasticSearch
时,我得到了这个:
Stopping ElasticSearch...
Stopped ElasticSearch.
Starting ElasticSearch...
Waiting for ElasticSearch.......
WARNING: ElasticSearch may have failed to start.
它确实无法启动。我检查了日志文件中是否有任何错误,但这就是全部:
[2013-04-03 22:31:00,788][INFO ][node ] [Chamber] {0.20.6}[4354]: initializing ...
[2013-04-03 22:31:00,797][INFO ][plugins ] [Chamber] loaded [], sites []
它没有任何错误就停在那里,没有继续。
有没有人成功获得ElasticSearch
之前在Rackspace云中工作?我知道单播选项也可用,但我不想单独指定每个IP地址,因为我希望以后可以很容易地添加其他节点。谢谢!
更新
我还没有解决这个问题,但经过一番搜索后我发现这个post表示“旧”云插件已经停止使用,只替换为亚马逊云的Ec2插件,解释了为什么我对配置文件所做的更改不起作用。
答案 0 :(得分:0)
出于安全原因,在公共云上禁用了多播(可以使用ifconfig
进行验证)。这篇文章应该能满足您的需求:
