详细内容如下:

---
# Remember, leave a key empty if there is no value.  None will be a string,
# not a Python "NoneType"
client:
  hosts:
    - 201.101.101.101
  port: 端口
  url_prefix:
  use_ssl: False
  certificate:
  client_cert:
  client_key:
  ssl_no_validate: False
  http_auth: 用户名:密码
  timeout: 30
  master_only: False

logging:
  loglevel: INFO
  logfile: /data/elasticsearch-curator/log/curator.log
  logformat: default
  blacklist: [elasticsearch, urllib3]

 详细内容如下:

---
# Remember, leave a key empty if there is no value.  None will be a string,
# not a Python "NoneType"
#
# Also remember that all examples have disable_action set to True.  If you
# want to use this action as a template, be sure to set this to False after
# copying it.
actions:
  1:
    action: delete_indices
    description: >-
      Delete metric indices older than 3 days (based on index name), for
      .monitoring-es-6-
      .monitoring-kibana-6-
      .monitoring-logstash-6-
      .watcher-history-3-
      prefixed indices. Ignore the error if the filter does not result in an
      actionable list of indices (ignore_empty_list) and exit cleanly.
    options:
      ignore_empty_list: True
 #     disable_action: True
    filters:
    - filtertype: pattern
      kind: regex
      value: ^mysql-.*$
    - filtertype: age
      source: name
      direction: older
      timestring: %Y.%m.%d
      unit: days
      unit_count: 3

  2:
    action: close
    description: >-
      Close indices older than 30 days (based on index name), for syslog-
      prefixed indices.
    options:
      ignore_empty_list: True
      delete_aliases: False
#      disable_action: True
    filters:
    - filtertype: pattern
      kind: prefix
      value: syslog-
    - filtertype: age
      source: name
      direction: older
      timestring: %Y.%m.%d
      unit: days
      unit_count: 30

  3:
    action: forcemerge
    description: >-
      forceMerge syslog- prefixed indices older than 2 days (based on index
      creation_date) to 2 segments per shard.  Delay 120 seconds between each
      forceMerge operation to allow the cluster to quiesce. Skip indices that
      have already been forcemerged to the minimum number of segments to avoid
      reprocessing.
    options:
      ignore_empty_list: True
      max_num_segments: 2
      delay: 120
      timeout_override:
      continue_if_exception: False
    filters:
    - filtertype: pattern
      kind: prefix
      value: syslog-
      exclude:
    - filtertype: age
      source: name
      direction: older
      timestring: %Y.%m.%d
      unit: days
      unit_count: 2
    - filtertype: forcemerged
      max_num_segments: 2
      exclude:

Step 5 使用crontab定期执行curator

设置定时任务,例如以下的crontab

6 0 * * * curator --config /data/elasticsearch-curator/config.yml /data/elasticsearch-curator/action.yml
