坑1 es-head 无法连接，检查跨域问题

/elasticsearch.yml

http.cors.enabled: true

http.cors.allow-origin: "*"

坑2 es-head 操作406:Not Acceptable错误

修改vendor.js

contentType: "application/x-www-form-urlencoded" 修改为 contentType: "application/json;charset=UTF-8"

var inspectData = s.contentType === "application/x-www-form-urlencoded" && 修改为 var inspectData = s.contentType === "application/json;charset=UTF-8" &&

坑3 集群各个节点不能聚合，各自成为独立集群

discovery.seed_hosts: ["192.168.0.11", "192.168.0.12"]

在第一个节点上不能使用这个，否则将各自成为一个集群，无法将两个节点组成一个集群。

如果cluster.initial_master_nodes:["node-1","node-2"] 应该也可以解决问题，待测试。

坑4 filebeat 配置中使用默认模板的问题

setup.ilm.enabled: false #不继承索引模板

配置示例

filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /var/log/nginx/access.log
  json.keys_under_root: true
  json.overwrite_keys: true
  tags: ["access"]
- type: log
  enabled: true
  paths:
    - /var/log/nginx/error.log
  tags: ["error"]

setup.ilm.enabled: false

setup.template.settings:
  index.number_of_shards: 3
setup.kibana:
  host: "211.149.144.72:5601"
output.elasticsearch:
  hosts: ["211.149.144.72:9200"]
  indices:
    - index: "nginx_access-%{[agent.version]}-%{+yyyy.MM.dd}"
      when.contains:
        tags: "access"
    - index: "nginx_error-%{[agent.version]}-%{+yyyy.MM.dd}"
      when.contains:
        tags: "error"
setup.template.name: "nginx"
setup.template.pattern: "nginx_*"
setup.template.enabled: false
setup.template.overwrite: true
