有的时候我们在使用ES时，由于资源有限或业务需求，我们只想保存最近一段时间的数据，所以有如下脚本可以定时删除数据

delete_es_by_day.sh

[plain]
view plain
copy

#!/bin/sh  
# example: sh  delete_es_by_day.sh logstash-kettle-log logsdate 30  
  
index_name=$1  
daycolumn=$2  
savedays=$3  
format_day=$4  
  
if [ ! -n "$savedays" ]; then  
  echo "the args is not right,please input again...."  
  exit 1  
fi  
  
if [ ! -n "$format_day" ]; then  
   format_day='%Y%m%d'  
fi  
  
sevendayago=`date -d "-${savedays} day " +${format_day}`  
  
curl -XDELETE "10.130.3.102:9200/${index_name}/_query?pretty" -d "  
{  
        "query": {  
                "filtered": {  
                        "filter": {  
                                "bool": {  
                                        "must": {  
                                                "range": {  
                                                        "${daycolumn}": {  
                                                                "from": null,  
                                                                "to": ${sevendayago},  
                                                                "include_lower": true,  
                                                                
4000
"include_upper": true  
                                                        }  
                                                }  
                                        }  
                                }  
                        }  
                }  
        }  
}"  
  
echo "ok"  

注解：脚本传入参数说明：1.索引名；2.日期字段名；3.保留最近几天数据，单位天；4.日期格式，可不输（默认形式20160101）
