我是Elasticsearch的新手，并且遇到了这个错误。

Elasticsearch::Transport::Transport::Errors::ServiceUnavailable at /search

[503] {"error":"SearchPhaseExecutionException[Failed to execute phase [query], all shards failed]","status":503}

这是完整的错误日志

这是 visitors_controller.rb中的那段代码，被认为是错误背后的原因。

@search_results = Property.where(property_active: true)

 ### new search
 results   = CityCoordinate.search(params[:q]).records
 if params[:q].present? && results.present? #line 34
 latitude  = results.first.latitude
 longitude = results.first.longitude
 city      = Property.new("latitude" => latitude, "longitude" => longitude)
 @search_results = city.nearbys(200).where(property_active: true)
 end
 ###

这些是请求参数

{"utf8"=>"✓", "q"=>"Holtsville, NY, United States", "min"=>"", "max"=>"", "baths"=>"", "beds"=>"", "property_type"=>"", "pet"=>"", "garage"=>"", "controller"=>"visitors", "action"=>"search"}

我在 Gemfile中有这些

gem 'elasticsearch-model', '0.1.6'
gem 'elasticsearch-rails', '0.1.6'
gem 'bonsai-elasticsearch-rails', '0.0.4'

我不知道发生了什么，我对此一无所知。在我们的rails应用程序中，我们使用 elasticsearch作为 renters来搜索 properties发布的 landlords，其中 city,state and country是 的参数q 的参数。当前有一个具有给定城市 Holtsville 的属性(property)。

请询问是否需要任何信息。

更新2:

我取消注释并在 elasticsearch.yml文件中添加了这些内容

node.name: "Franz Kafka"
node.master: true
node.data: true
cluster.routing.allocation.disk.threshold_enabled: true
cluster.routing.allocation.disk.watermark.low: 97
cluster.routing.allocation.disk.watermark.high: 99
bootstrap.mlockall: true
network.bind_host: localhost
script.disable_dynamic: true
network.publish_host: localhost

我在 elasticsearch中创建了一个名为 /etc/init.d的可执行文件，以添加这些 environment variables

ES_MIN_MEM=256m
ES_MAX_MEM=1g

我运行 curl -XGET http://localhost:9200/_cluster/health?pretty时的输出

  "active_shards" : 3,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 17
}

更新4:

根据这个 link，看来我的机器没有最低 8GB的RAM(我有4GB)。这是错误的原因吗？并且 city_coordinates表( elasticsearch从中收集数据)具有 43k 记录，这使我有足够的理由相信当前内存( 4GB )不足以容纳 elasticsearch。

更新5:

我运行 curl 'localhost:9200/_cat/nodes?v'时的输出

最佳答案

您的问题记录在这里:

Primary shard is not active or isn't assigned is a known node.

这通常意味着Elasticsearch无法为您的索引创建主分片。通常是因为您的磁盘太满了:

cluster.routing.allocation.disk.watermark.low controls the low watermark for disk usage. It defaults to 85%, meaning ES will not allocate new shards to nodes once they have more than 85% disk used.

http://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules-allocation.html

您可能应该将Elasticsearch日志级别设置为DEBUG以获得更多信息。

编辑:根据分片调试输出，看起来您已经用20个分片创建了索引，但是您的节点容纳不了那么多分片。

The index.routing.allocation.total_shards_per_node setting allows to control how many total shards (replicas and primaries) for an index will be allocated per node.

您应该将 number_of_replicas和 number_of_shards设置为值，以使 number_of_shards * number_of_replicas小于 index.routing.allocation.total_shards_per_node且 number_of_replicas不大于集群中的节点数，来重新创建索引。
