有安装完成后在ES的配置文件config/elasticsearch.yml中增加ik的配置，在最后增加：

index:
  analysis:                   
    analyzer:      
      ik:
          alias: [ik_analyzer]
          type: org.elasticsearch.index.analysis.IkAnalyzerProvider
      ik_max_word:
          type: ik
          use_smart: false
      ik_smart:
          type: ik
          use_smart: true

最后启动时会报错：节点设置不能包含任何索引级别设置

也就是说报错是因为在elasticsearce.yml文件中对索引进行了配置，删除相应的索引配置即可.

从 elasticsearch 5.x index level settings can NOT be set on the nodes 。

Found index level settings on node level configuration.

Since elasticsearch 5.x index level settings can NOT be set on the nodes 
configuration like the elasticsearch.yaml, in system properties or command line 
arguments.In order to upgrade all indices the settings must be updated via the 
/${index}/_settings API. Unless all settings are dynamic all indices must be closed 
in order to apply the upgradeIndices created in the future should use index templates 
to set default values. 

Please ensure all required values are updated on all indices by executing: 

curl -XPUT 'http://localhost:9200/_all/_settings?preserve_existing=true' -d '{
  "index.analysis.analyzer.ik.alias[0]" : "ik_analyzer",
  "index.analysis.analyzer.ik.type" : "org.elasticsearch.index.analysis.IkAnalyzerProvider",
  "index.analysis.analyzer.ik_max_word.type" : "ik",
  "index.analysis.analyzer.ik_max_word.use_smart" : "false",
  "index.analysis.analyzer.ik_smart.type" : "ik",
  "index.analysis.analyzer.ik_smart.use_smart" : "true"
}'
