Elasticsearch索引恢复
以下是Elasticsearch备份还原的方法和步骤:
备份:
1.创建一个仓库,用于存储快照。例如,创建一个名为my_backup的仓库,路径为/backups/my_backup:
```shell
PUT _snapshot/my_backup
{
"type": "fs",
"settings": {
"location": "/backups/my_backup"
}
}
```
2.创建一个快照,例如,创建一个名为snapshot_1的快照:
```shell
PUT _snapshot/my_backup/snapshot_1
```
3.等待快照完成,可以使用以下命令检查快照状态:
```shell
GET _snapshot/my_backup/snapshot_1
```
还原:
1.关闭索引,例如,关闭名为my_index的索引:
```shell
POST /my_index/_close
```
2.还原快照,例如,还原名为snapshot_1的快照到my_index索引:
```shell
POST /_snapshot/my_backup/snapshot_1/_restore
{
"indices": "my_index",
"ignore_unavailable": true,
"include_global_state": false
}
```
3.等待还原完成,可以使用以下命令检查还原状态:
```shell
GET /_cat/recovery/my_index
```
