elasticsearch数据迁移

一、背景

1. 版本elasticsearch-7.17.1
2. es单节点
3. 使用docker安装

二、导出数据

1. 查询docker es的信息

(base) [root@localhost ~]# docker ps
5019ca7f9bb3   elasticsearch:7.17.1                        "/bin/tini -- /usr/l…"   2 months ago    Up 4 weeks             0.0.0.0:9200->9200/tcp, :::9200->9200/tcp, 0.0.0.0:9300->9300/tcp, :::9300->9300/tcp                                                  elasticsearch-7.17.1

1. 查询数据目录（/home/es/data）

(base) [root@localhost ~]# docker inspect 5019ca7f9bb3 | grep -A 10 "Mounts""Mounts": [{"Type": "bind","Source": "/home/es/data","Destination": "/usr/share/elasticsearch/data","Mode": "","RW": true,"Propagation": "rprivate"},{"Type": "bind",

1. 整个数据目录copy并压缩

# 进入数据目录
cd /home/es/data
# 压缩数据目录（使用gzip，速度快且压缩率高）
tar -zcvf elasticsearch_data.tar.gz .

三、导入数据

1. 将数据包上传到目标服务器的es数据目录
2. 解压

# 解压到目标数据目录
cd /home/es/data
tar -zxvf /tmp/elasticsearch_data.tar.gz

1. 重启es

docker start elasticsearch-7.17.1

四、验证数据

1. 查询下所有索引信息

(base) [root@localhost config]# curl 'http://localhost:9300/_cat/indices?v&pretty'
curl: (56) Recv failure: 连接被对方重设
(base) [root@localhost config]# curl 'http://localhost:9200/_cat/indices?v&pretty'

1. 获取索引 aircraft_adsb 前十条数据

curl -X GET "http://localhost:9100/aircraft_adsb/_search?pretty" -H "Content-Type: application/json" -d '
{"size": 10,"query": {"match_all": {}}
}'
