ElasticSearch 6.x 学习笔记：3.Kibana插件_[插件:elasticsearch @6.2.2]状态从黄色变为红色——这个kibana版本要求所有

3.1 下载Kibana插件

https://www.elastic.co/downloads/kibana

注意，ElasticSearch版本是6.1.1，kibana的版本必须对应，所以，此处下载kibana-6.1.1-linux-x86_64.tar.gz

[es@node1 ~]$ wget https://artifacts.elastic.co/downloads/kibana/kibana-6.1.1-linux-x86_64.tar.gz

3.3 修改配置

修改kibana配置文件kibana.yml

[es@node1 kibana-6.1.1-linux-x86_64]$ vi config/kibana.yml 
1

需要配置两处
（1）kibana向外提供服务，运行远程用户访问

# To allow connections from remote users, set this parameter to a non-loopback address.
server.host: "node1"

2

（2）配置elasticsearch.url

# The URL of the Elasticsearch instance to use for all your queries.
elasticsearch.url: "http://node1:9200"

3.5 简单应用

curl -XGET “http://node1:9200/test/_search”

{"took":3,"timed_out":false,"_shards":{"total":5,"successful":5,"skipped":0,"failed":0},"hits":{"total":0,"max_score":null,"hits":[]}}[root@node1 ~]#

3.6 可能遇到的问题

启动kibana后关闭shell窗口后kibana自动关闭
解决办法：退出当前登录窗口用exit命令，不要直接点击窗口上的叉来关闭

[elastic@node1 kibana-5.6.9]$ bin/kibana &
[1] 9709
[elastic@node1 kibana-5.6.9]$   log   [14:50:31.223] [info][status][plugin:kibana@5.6.9] Status changed from uninitialized to green - Ready

  log   [14:50:31.448] [info][status][plugin:metrics@5.6.9] Status changed from uninitialized to green - Ready
  log   [14:50:31.489] [info][status][plugin:elasticsearch@5.6.9] Status changed from yellow to green - Kibana index ready
  log   [14:50:31.737] [info][status][plugin:timelion@5.6.9] Status changed from uninitialized to green - Ready
  log   [14:50:31.743] [info][listening] Server running at http://node1:5601
  log   [14:50:31.745] [info][status][ui settings] Status changed from uninitialized to green - Ready

[elastic@node1 kibana-5.6.9]$ 
[elastic@node1 kibana-5.6.9]$ exit
