elasticsearch-curator: es索引生命周期（关闭、删除索引）

本文主要是介绍elasticsearch-curator: es索引生命周期（关闭、删除索引），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1，下载安装

rpm包下载安装

# 防止安装rpm包报错：error: [upel]: elasticsearch-curator NOKEY ； 
#                  error: [upel]: elasticsearch-curator signature check fail
rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch #参考https://www.elastic.co/guide/en/elasticsearch/reference/7.17/rpm.htmlrpm -ivh https://packages.elastic.co/curator/5/centos/7/Packages/elasticsearch-curator-5.8.4-1.x86_64.rpm

参考：https://www.elastic.co/guide/en/elasticsearch/client/curator/current/installation.html

2, 配置使用

配置

关闭索引，action.yaml 加上 ignore_empty_list: True, 防止条件不满足时报错，导致任务不能继续执行
删除索引，action.yaml 加上continue_if_exception: True , 防止删除索引报错，导致任务不能继续执行
action.yaml 配置参考：
action-close模板：https://www.elastic.co/guide/en/elasticsearch/client/curator/current/ex_close.html
索引名匹配-正则参考：https://www.elastic.co/guide/en/elasticsearch/client/curator/current/filtertype_pattern.html
