elasticsearch6.8.11备份至minio

1.（所有节点执行）在线安装repository-s3插件

bin/elasticsearch-plugin install repository-s3

修改安装目录的属组
安装完成后重启所有节点服务

2.（所有节点执行）配置access_key，请使用minio的实际access-key权限

bin/elasticsearch-keystore add s3.client.default.access_key

3.（所有节点执行）配置secret_key，请使用minio的实际secret-key权限

bin/elasticsearch-keystore add s3.client.default.secret_key

4.（所有节点执行）所有节点配置文件增加配置如下,endpoint只能填写IP地址，不能填写域名

# minio的api连接地址，不能写域名（域名无法解析），只能写IP地址
s3.client.default.endpoint: 192.168.1.123:9000
s3.client.default.protocol: http


修改安装目录的属组
修改完配置后重启所有节点服务生效

5.创建s3备份仓库

注意：须在minio中提前创建bucket:es-backup

curl -uelastic:f3g5OxRbxcFITUqIQfMc -XPUT 'http://localhost:9200/_snapshot/backup' -H 'Content-Type: application/json' -d '{ "type": "s3", "settings": { "bucket": "es-backup"} }' 

6.查看仓库状态

curl -uelastic:f3g5OxRbxcFITUqIQfMc -XPOST http://localhost:9200/_snapshot/backup/_verify?pretty

7.备份所有索引

curl -uelastic:f3g5OxRbxcFITUqIQfMc -XPUT http://localhost:9200/_snapshot/backup/snapshot_all_3?wait_for_completion=true

8.查看所有备份快照信息

curl -uelastic:f3g5OxRbxcFITUqIQfMc -XGET http://localhost:9200/_snapshot/backup/_all?pretty

9.删除快照

curl -uelastic:f3g5OxRbxcFITUqIQfMc -XDELETE localhost:9200/_snapshot/backup/snapshot_all_4?pretty

10.恢复备份

curl -uelastic:f3g5OxRbxcFITUqIQfMc -XPOST http://localhost:9200/_snapshot/backup/snapshot_all_2/_restore

11.恢复备份中的指定索引

curl -uelastic:f3g5OxRbxcFITUqIQfMc -XPOST http://localhost:9200/_snapshot/backup/snapshot_all_4/_restore -H 'Content-Type: application/json'  -d'{ "indices": "lrh_index","ignore_unavailable": true, "include_global_state": false }'

12.创建索引

curl -uelastic:f3g5OxRbxcFITUqIQfMc -XPUT 'http://localhost:9200/lrh_index' 

13.删除索引

curl -uelastic:f3g5OxRbxcFITUqIQfMc -XDELETE 'http://localhost:9200/lrh_index'
