es导出oracle,es备份迁移到另外的机器

1.在原来的机器上进行备份(我这里备份只保留2天,所以多了些处理脚本)

##创建备份仓库目录

curl -H "Content-Type: application/json" -XPUT -d'{

"type": "fs",

"settings": {

"location": "/home/yeemiao/single_elasticsearch/esbak"

}

}'

##备份

curl -H "Content-Type: application/json" -XPUT /snapshot_20190815

2.查看备份情况

curl -X GET "/_all?pretty"

我这里已经有备份,查看备份情况

[yeemiao@localhost esbak]$ curl -X GET "/_all?pretty"

{

"snapshots" : [

{

"snapshot" : "snapshot_20190815",

"uuid" : "jZk8QYgISMmkc1qpNB4BZw",

"version_id" : 6050099,

"version" : "6.5.0",

"indices" : [

"reservation_hxl",

"reservation",

"vacc_update",

"reservation_new",

"child_inocexamine_student_inoculation1",

"child_inocexamine_vacc",

"hxl_update",

"bak01_hxl_test",

"child_inocexamine_student",

"bak_hxl_test",

"child_inocexamine_student_inoculation",

"inoculate_new",

"update",

"bak02_hxl_test",

"inoculate",

".security-6"

],

"include_global_state" : true,

"state" : "IN_PROGRESS",

"start_time" : "2019-08-15T05:45:40.443Z",

"start_time_in_millis" : 1565847940443,

"end_time" : "1970-01-01T00:00:00.000Z",

"end_time_in_millis" : 0,

"duration_in_millis" : -1565847940443,

"failures" : [ ],

"shards" : {

"total" : 0,

"failed" : 0,

"successful" : 0

}

}

]

}

3.将es备份目录打包,然后上传到新部署的机器上面

[yeemiao@localhost single_elasticsearch]$ cd /home/yeemiao/single_elasticsearch

tar -czvf esbak20190815.tar ./esbak

scp esbak20190815.tar yeemiao@192.168.1.134:/tmp/

4.新机器安装部署es

安装步骤省略,特别注意如下参数必须跟原来机器一致,因为我们等会将原来机器的备份文件加压到该目录

path.repo: /home/yeemiao/single_elasticsearch/esbak

5.将原主机备份的文件解压到新机器path.repo参数指定的目录

[yeemiao@localhost tmp]$ cd /tmp/

[yeemiao@localhost tmp]$ tar -xvf esbak20190815.tar

[yeemiao@localhost esbak]$ cd /tmp/esbak

[yeemiao@localhost esbak]$ cp -r ./* /home/yeemiao/single_elasticsearch/esbak

6.执行恢复

新的机器这个时候是没有index的

[yeemiao@localhost esbak]$ curl -X GET ''

health status index uuid pri rep docs.count docs.deleted store.size pri.store.size

执行恢复步骤

6.1 创建备份指定目录

curl -H "Content-Type: application/json" -XPUT -d'{

"type": "fs",

"settings": {

"location": "/home/yeemiao/single_elasticsearch/esbak"

}

}'

6.2 查看备份信息,这个时候备份信息已经注册进来了

curl -X GET "/_all?pretty"

6.3 执行恢复

curl -XPOST /snapshot_20190815/_restore

7.验证

[yeemiao@localhost esbak]$ curl -X GET ''

这里输出查看到跟原来的主机结果一致
