- Elasticsearch snapshot简介
快照一般建立在一个共享的文件系统上,这样的话有一个节点快照,别的节点也是可以看到的,这样删除的时候也可以同时删除,(在最新版里面创建仓库如果未使用共享文件系统会提示你,在其他节点未找到对应的仓库)。
- 注册快照仓库
注意这里的“location”目录必须是“path.repo”里面指定的,或者子目录。
[[email protected] elasticsearch]# curl -XPUT ‘http://localhost:9200/_snapshot/my_backup‘ -d ‘{ "type": "fs", "settings": {"location": "/data1/backup/nginx-log","compress": true} }‘
查看快照仓库
“compress ” ——是否压缩
[[email protected] elasticsearch]# curl -XGET ‘http://localhost:9200/_snapshot/my_backup?pretty‘ -d ‘{ "my_backup":{ "type":"fs", "setting":{ "compress":"true", "location":"/data1/backup/nginx-log" }}}‘
3. 创建快照
[[email protected] ~]# curl -XPUT "localhost:9200/_snapshot/my_backup/nginx-log" -d ‘{ > "indices": "nginx-log", > "include_global_state": false > }‘
查看快照
[[email protected] indices]# curl -XGET "localhost:9200/_snapshot/my_backup/nginx-log"?pretty=1 { "snapshots" : [ { "snapshot" : "nginx-log", "version_id" : 1070199, "version" : "1.7.1", "indices" : [ "nginx-access-log" ], "state" : "SUCCESS", "start_time" : "2015-08-25T15:16:46.846Z", "start_time_in_millis" : 1440515806846, "end_time" : "2015-08-25T15:16:47.458Z", "end_time_in_millis" : 1440515807458, "duration_in_millis" : 612, "failures" : [ ], "shards" : { "total" : 5, "failed" : 0, "successful" : 5 } } ]
}
4. 恢复快照
因为这里快照里只有一个索引所以不管直接恢复全部
[[email protected] indices]# curl -XPOST "localhost:9200/_snapshot/my_backup/nginx-log/_restore" {"accepted":true}
当您有多个索引在快照里面,就可以用到下面的方式啦~~~
curl -XPOST "localhost:9200/_snapshot/my_backup/nginx-log/_restore" -d ‘{
"indices": "index_1,index_2",
"ignore_unavailable":
"true",
"include_global_state":
false,
"rename_pattern":
"index_(.+)",
"rename_replacement":
"restored_index_$1"
}‘
5. 删除全部快照
[[email protected] indices]# curl -XDELETE http://127.0.0.1:9200/_snapshot/my_backup/nginx-log {"acknowledged":true}
