一、下载安装

  • 下载：sudo pip install elasticsearch-curator
  • 更新：sudo pip install -U elasticsearch-curator

版本：curator4.1.0

二、配置文件

1、config.yml

 # Remember, leave a key empty if there is no value.  None will be a string,

 # not a Python "NoneType"

 client:

   hosts: ["127.0.0.1:9200"]

   url_prefix:

   use_ssl: False

   certificate:

   client_cert:

   client_key:

   aws_key:

   aws_secret_key:

   aws_region:

   ssl_no_validate: False

   http_auth:

   timeout: 30

   master_only: False

 logging:

   loglevel: INFO

   logfile:

   logformat: default

   blacklist: ['elasticsearch', 'urllib3']

2、action.yml

 ---

 # 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 indices older than 45 days (based on index name), for logstash- prefixed indices.

                   Ignore the error if the filter does not result in an actionable list of indices (ignore_empty_list) and exit cleanly"

     options:

       timeout_override:

       continue_if_exception: False

       disable_action: False

     filters:

     - filtertype: pattern

       kind: prefix

       value: logstash-

       exclude:

     - filtertype: age

       source: name

       direction: older

       timestring: '%Y.%m.%d'

       unit: days

       unit_count: 5

       exclude:

注意：action上边那个1是action id，必须得有

说明：

三、测试

curator --config ~/Desktop/server/elk/es-curator-4.1.0/config.yml ~/Desktop/server/elk/es-curator-4.1.0/action.yml

四、做成Linux定时任务

1、编写sh脚本：curator-delete-index.sh

#!/bin/sh

/usr/local/bin/curator --config /Users/enniu1/Desktop/server/elk/es-curator-4.1.0/config.yml /Users/enniu1/Desktop/server/elk/es-curator-4.1.0/action.yml

echo "delete index success"

注意：最好使用命令的全路径名，否则可能找不到。

2、赋予权限

  • chmod 777 /Users/enniu1/Desktop/server/elk/es-curator-4.1.0/curator-delete-index.sh

3、创建定时任务：crontab

  • crontab -e：打开了vi，输入：

    • 30 16 * * * /Users/enniu1/Desktop/server/elk/es-curator-4.1.0/curator-delete-index.sh，之后保存退出vi

  • crontab -l：查看所有的root用户的定时任务

附：crontab的文件格式

分 时 日 月 星期 要运行的命令

  • 第1列分钟1～59
  • 第2列小时1～23（0表示子夜）
  • 第3列日1～31
  • 第4列月1～12
