IMPORTANT: Version 6.6 of Elasticsearch has passed its maintenance date.
This documentation is no longer being updated. For the latest information, see the current release documentation.
If you are using the
.tar.gz archives, the
directories are sub-folders of
$ES_HOME. If these important folders are left
in their default locations, there is a high risk of them being deleted while
upgrading Elasticsearch to a new version.
In production use, you will almost certainly want to change the locations of the data and log folder:
path: logs: /var/log/elasticsearch data: /var/data/elasticsearch
The RPM and Debian distributions already use custom paths for
path.data settings can be set to multiple paths, in which case all paths
will be used to store data (although the files belonging to a single shard will
all be stored on the same data path):
path: data: - /mnt/elasticsearch_1 - /mnt/elasticsearch_2 - /mnt/elasticsearch_3
