无法在Elasticsearch中注册快照存储库

Question

我正在使用Elasticsearch 1.4和ubuntu 12.04.3 LTS.Trying为Local elasticsearch创建快照.我推荐这个网站

这个网站的步骤在Windows Elasticsearch上正常运行.如果我在Ubuntu Elasticsearch上注册存储库.它发射下面的消息.

这个查询我运行的是什么

curl -XPUT http://xx.xx.xx.xx:9200/_snapshot/es_snap -d '{
  "type": "fs",
  "settings": {
    "location": "/mount/backups/my_backup"
  }
}'

我得到了这个回复.

{
  "error":"RepositoryException[[es_snap] failed to create repository]; 
            nested: CreationException[Guice creation errors:\n\n1) Error injecting constructor, org.elasticsearch.common.blobstore.BlobStoreException:

            ]; 
            nested: BlobStoreException[Failed to create directory at [/mount/backups/my_backup]]; ",
  "status":500
}

Answer 1

1. 首先创建一个备份文件夹(通常该文件夹创建用户主文件夹)

   mkdir ~/backup
   

2. 授予该文件夹的权限

   chmod 777 ~/backup
   

3. 创建存储库(存储库代表您的路径)

   curl -XPUT http://xx.xx.xx.xx:9200/_snapshot/es_snap -d 
   '{"type":"fs","settings":{"location":"home/user/backup"
   ,"compress":true}}'
   

4. 快照

   curl -XPUT "http://xx.xx.xx.xx:9200/_snapshot/en_snap/snapshot_1" -d 
   '{"indices":["index1","index2","index3"],"ignore_unavailable":true,
   "include_global_state": false,}'
   

5. 恢复

   curl -XPOST "http://xx.xx.xx.xx:9200/_snapshot/es_snap/snapshot_1/_restore" -d 
   '{"indices":["index1","index2"],"ignore_unavailable":true,
   "include_global_state": false}'
