查看索引
在elasticsearch节点上使用curl -XGET 'http://XX.XX.X.XX:9200/_cat/shards'查看索引
[root@192-168-x-x scripts]# curl -XGET 'http://192.168.x.x:9200/_cat/shards' | more

过滤索引
将过滤出来要删除的索引存到临时文件夹里面（过滤条件根据实际情况修改）
[root@192-168-x-x ~]# curl -XGET 'http://192.168.x.x:9200/_cat/shards' | grep 192.168.x.x | grep 2018 | awk '{print $1}' |uniq > elk-index.tmp

批量删除
for i in `cat elk-index.tmp`
do
curl -XDELETE http://192.168.3.163:9200/$i
done
定时删除
使用脚本加定时任务，每一天删除前三天的索引
[root@192-168-x-x ~]# cat /home/scripts/del_elasticseatch_index.sh
#!/bin/bash
curl -XGET 'http://192.168.x.x:9200/_cat/shards' |grep 192.168.x.x | awk '{print $1}' |grep `date -d "5 days ago" +%Y.%m.%d` | uniq > /tmp/index_name.tmp
for index_name in `cat /tmp/index_name.tmp`
do
echo $index_name
curl -XDELETE http://192.168.x.x:9200/$index_name
echo "${index_name} delete success" >> /home/scripts/del_elasticseatch_index.log
done
