Separating Elastic configuration and data directory


(Robert Baxter) #1

We would like to separate the elasticsearch configuration (confg, logs, plugins, work) location from the data directory where all the index files are stored (primarly to put the data directory on a partition that with more capable/expandable storage).

Has anyone done this, anything we should be concerned about with this approach?

Additionally, to do this on an existing cluster is it as simple as shutting down the node, updating the elasticsearch.yml file to adjust the "path.data" setting?

Hi,

It depends how Elasticsearch has been installed.

If you installed ES using a tar.gz archive, then you just have to configure path.data, path.conf, path.plugins etc in elasticsearch.yml and move the existing directories and files.

If you installed ES using a deb/rpm it's a bit different (but almost as simple) and you should check the documentation here : https://www.elastic.co/guide/en/elasticsearch/reference/5.2/install-elasticsearch.html
