To upgrade using a <<deb,Debian>> or <<rpm,RPM>> package:
|
|
|
|
* Use `rpm` or `dpkg` to install the new package. All files are
|
|
installed in the appropriate location for the operating system
|
|
and {es} config files are not overwritten.
|
|
|
|
To upgrade using a zip or compressed tarball:
|
|
|
|
.. Extract the zip or tarball to a _new_ directory. This is critical if you
|
|
are not using external `config` and `data` directories.
|
|
|
|
.. Set the `ES_PATH_CONF` environment variable to specify the location of
|
|
your external `config` directory and `jvm.options` file. If you are not
|
|
using an external `config` directory, copy your old configuration
|
|
over to the new installation.
|
|
|
|
.. Set `path.data` in `config/elasticsearch.yml` to point to your external
|
|
data directory. If you are not using an external `data` directory, copy
|
|
your old data directory over to the new installation. +
|
|
+
|
|
IMPORTANT: If you use {monitor-features}, re-use the data directory when you upgrade
|
|
{es}. Monitoring identifies unique {es} nodes by using the persistent UUID, which
|
|
is stored in the data directory.
|
|
|
|
|
|
.. Set `path.logs` in `config/elasticsearch.yml` to point to the location
|
|
where you want to store your logs. If you do not specify this setting,
|
|
logs are stored in the directory you extracted the archive to.
