//This content is referenced from the elastic/elasticsearch/docs/reference/modules/node.asciidoc

If {xpack} is installed, there is an additional node type:
如果安装了 {xpack}，那么有一个额外的节点类型：

<<ml-node,Machine learning node>>::
<<ml-node,机器学习节点>>::

A node that has `xpack.ml.enabled` and `node.ml` set to `true`, which is the
default behavior when {xpack} is installed. If you want to use {xpackml}
features, there must be at least one {ml} node in your cluster. For more
information about {xpackml} features,
see {xpack-ref}/xpack-ml.html[Machine Learning in the Elastic Stack].
将 `xpack.ml.enabled` 和 `node.ml` 设置为 `true` 的节点，安装 {xpack} 时的默认行为。如果您想使用 {xpackml} 功能，集群中必须至少有一个 {ml} 节点。更多有关 {xpackml} 功能的信息，参见 {xpack-ref}/xpack-ml.html[Machine Learning in the Elastic Stack]。

IMPORTANT: Do not set use the `node.ml` setting unless {xpack} is installed.
Otherwise, the node fails to start.
IMPORTANT: 除非安装了 {xpack}，否则不要设置使用 `node.ml` 设置。否则，节点无法启动。

If {xpack} is installed, nodes are master-eligible, data, ingest, and {ml}
nodes by default. As the cluster grows and in particular if you have large
{ml} jobs, consider separating dedicated master-eligible nodes from dedicated
data nodes and dedicated {ml} nodes.
如果安装了xpack，则节点默认是候选主节点、数据节点、摄取节点和 {ml} 节点。随着集群的增长，尤其是有大量 {ml} 作业时，考虑将专用候选主节点与专用数据节点和专用 {ml} 节点分开。

The {xpackml} features provide {ml} nodes, which run jobs and handle {ml} API
requests. If `xpack.ml.enabled` is set to true and `node.ml` is set to `false`,
the node can service API requests but it cannot run jobs.
{xpackml} 功能提供了 {ml} 节点，用来运行任务和处理 {ml} API 请求。 如果 `xpack.ml.enabled` 设置为 true 并且 `node.ml` 设置为 `false`，那么该节点可服务于 API 请求但不能运行任务。

If you want to use {xpackml} features in your cluster, you must enable {ml}
(set `xpack.ml.enabled` to `true`) on all master-eligible nodes. Do not use
these settings if you do not have {xpack} installed.
如果想在集群中使用 {xpackml} 功能，必须在全部候选主节点上启用 {ml}。如果没有安装 {xpack}，不要使用这些设置。

For more information about these settings, see <<ml-settings>>.
