es索引管理工具-curator

elasticsearch-curator  是官方收购的开源社区周边产品,用来管理es的索引和快照。

官方文档:https://www.elastic.co/guide/en/elasticsearch/client/curator/current/index.html

功能包括:从别名添加、删除索引,更改分片路由分配,打开/关闭索引,创建/删除索引,快照管理、合并segment,更改索引分片副本数等。

目前使用的elasticsearch-curator版本是5.4, Python2.6安装会出现问题.建议在安装在python2.7+的环境中.

安装:

      # pip install elasticsearch-curator

使用:

命令语法:

命令行参数:  curator [--config CONFIG.YML] [--dry-run] ACTION_FILE.YML

$ curator --help
Usage: curator [OPTIONS] ACTION_FILE

  Curator for Elasticsearch indices.
  See http://elastic.co/guide/en/elasticsearch/client/curator/current
Options:
  --config PATH  Path to configuration file. Default: ~/.curator/curator.yml
  --dry-run      Do not perform any changes.  #  --dry-run参数在调试action_file时比较重要
  --version      Show the version and exit.
  --help         Show this message and exit.

curator运行需两个配置文件:

config.yml:用于连接ES集群配置

action.yml:用于配置要执行的操作,文件名称可以随意命名 

config.yml配置:

# cat curator.yml
# Remember, leave a key empty ifthere is no value.  None will be a string,
# not a Python "NoneType"
client:
  hosts:
    - 172.16.10.23
    - 172.16.10.24
    - 172.16.10.25
  port: 9200
  url_prefix:
  use_ssl: False
  certificate:
  client_cert:
  client_key:
  ssl_no_validate: False
  http_auth:
  timeout: 3600
  master_only: False
logging:
  loglevel: INFO
#  logfile: /home/test/curator.log
  logfile:
  logformat: default
  blacklist: ['elasticsearch', 'urllib3']

配置说明:

  • hosts: 同一个集群内节点IP,如果端口不同,可写成ip:port形式;只能一次使用一个集群。在主机设置中包含来自多个集群的节点将导致错误。
  • port: 默认值是9200。这个值只适用于没有端口的主机。
  • timeout:  默认值是30S,根据实际使用情况调整.
  • logfile: 默认值是空的,会将执行结果输出到STDOUT或控制台。如果指定文件,会把执行日志输出到文件中,而不是控制台.
  • blacklist:  默认值为'elasticsearch', 'urllib3'。Python模块不被输出。除非需要调试某些问题, 否则请使用默认值.

ACTION_FILE配置

配置说明:关闭前缀为syslog- 并且 时间格式为 '%Y.%m.%d'的7天前的所有的文档.

# cat action_close.yml
---
# Remember, leave a key empty ifthere 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 thisaction as a template, be sure to set thisto False after
# copying it.
actions:
  1:
    action: close
    description: >-
      Close indices older than 30days (based on index name), forlogstash-
      prefixed indices.
    options:
      delete_aliases: False
      disable_action: False
    filters:      # filters下的配置都是隐含的逻辑“AND”操作链接.
    - filtertype: pattern
      kind: prefix
      value: syslog-
    - filtertype: age
      source: name
      direction: older
      timestring: '%Y.%m.%d'
      unit: days
      unit_count: 7

curator_cli命令行命令行查看所有索引:

 # curator_cli --config   config.yml  action_close.yml  --verbose

执行命令:

# curator --config  config.yml   action_close.yml
