Set up X-Pack
安装X-Pack
X-Pack is an Elastic Stack extension that bundles security, alerting, monitoring, reporting, machine learning, and graph capabilities into one easy-to-install package. To access this functionality, you must install X-Pack in Elasticsearch.
X-Pack是一个可伸缩的栈扩展以及处理安全、警报、监控、报告、机器学习和图标能力的易于安装的组合。为了使用这些功能，你必须在Elasticsearch中安装X-Pack。
Installing X-Pack in Elasticsearch
在Elasticsearch中安装X-Pack
After you install Elasticsearch, you can optionally obtain and install X-Pack. For more information about how to obtain X-Pack, see https://www.elastic.co/products/x-pack.
在你安装Elasticsearch之后，你可以选择获取和安装X-Pack。关于如何获取X-Pack，请参考x-pack网站。
You must run the version of X-Pack that matches the version of Elasticsearch you are running.
你要运行的X-Pack的版本必须匹配你正在使用的Elasticsearch的版本。
Important

If you are installing X-Pack for the first time on an existing cluster, you must perform a full cluster restart. Installing X-Pack enables security and security must be enabled on ALL nodes in a cluster for the cluster to operate correctly. When upgrading you can usually perform a rolling upgrade.
如果你对于已有的集群首次安装X-Pack，你必须将整个集群重新启动。安装X-Pack必须保证安全并且对于集群中每个节点都必须正确操作。当你进行升级的时候你通常可以选择滚动升级。
To install X-Pack in Elasticsearch:
在Elasticsearch上安装X-Pack：
Optional: If you want to install X-Pack on a machine that doesn’t have internet access:
选项：如果你希望在没有网络的机器上安装X-Pack：Manually download the X-Pack zip file: https://artifacts.elastic.co/downloads/packs/x-pack/x-pack-5.5.2.zip (sha1)
手动下载X-Pack的zip文件：下载链接Note
注意
The plugins for Elasticsearch, Kibana, and Logstash are included in the same zip file. If you have already downloaded this file to install X-Pack on one of those other products, you can reuse the same file.
用于Elasticsearch、Kibana和Logstash的插件在相同的zip文件中。如果你已经下载了其中的这个文件来安装X-Pack，你可以重用相同的文件。Transfer the zip file to a temporary directory on the offline machine. (Do NOT put the file in the Elasticsearch plugins directory.)
将zip文件放置在离线机器的临时目录中。（不要文件放置在Elasticsearch插件目录下。）
Run bin/elasticsearch-plugin install from ES_HOME on each node in your cluster:
运行bin/elasticsearch-plugin从ES_HOME中开始安装对于你的集群中的每个节点：bin/elasticsearch-plugin install x-packNote
注意
If you are using a DEB/RPM distribution of Elasticsearch, run the installation with superuser permissions.
如果你使用使用Elasticsearch的DEB或RPM，使用超级管理员的权限来运行安装。The plugin install scripts require direct internet access to download and install X-Pack. If your server doesn’t have internet access, specify the location of the X-Pack zip file that you downloaded to a temporary directory.
插件安装脚本要求直接网络访问来下载和安装X-Pack。如果你的服务器没有网络访问，指定你下载到临时目录的X-Pack的zip文件的位置。bin/elasticsearch-plugin install file:///path/to/file/x-pack-5.5.2.zipNote
注意
You must specify an absolute path to the zip file after the file:// protocol.
你必须使用file://协议来指定zip文件的绝对路径。Confirm that you want to grant X-Pack additional permissions.
确认你已经被授予了X-Pack的额外的权限。Tip
提示
Specify the –batch option when running the install command to automatically grant these permissions and bypass these install prompts.
指定--batch选项在运行自动安装命令的时候赋予了这些全蝎和通过这些安装许可。- X-Pack needs these permissions to set the threat context loader during install so Watcher can send email notifications.
X-Pack需要这些权限来设置关键的上下文加载器在安装的过程中因此Watcher可以发送邮件提醒。

X-Pack will try to automatically create a number of indices within Elasticsearch. By default, Elasticsearch is configured to allow automatic index creation, and no additional steps are required. However, if you have disabled automatic index creation in Elasticsearch, you must configure action.auto_create_index in elasticsearch.yml to allow X-Pack to create the following indices:
X-Pack将试图自动创建一系列指定使用Elasticsearch。默认的，Elasticsearch可以被配置来允许自动创建索引并且不需要额外的步骤。然而，如果你需要关闭在Elasticsearch中的自动索引创建，你必须在elasticsearch.yml中配置action.auto_create_index来允许X-Pack来创建下面的指示：
action.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history*,.ml*Important
重要
If you are using Logstash or Beats then you will most likely require additional index names in your action.auto_create_index setting, and the exact value will depend on your local configuration. If you are unsure of the correct value for your environment, you may consider setting the value to * which will allow automatic creation of all indices.
如果你使用Logstash或Beats，你可能需要额外的索引名在你的action.auto_create_index设置中，并且值将会依赖于你本地的配置。如果你不能保证你环境中正确的值，你可以考虑设置值为*来允许自动创建所有的索引。Start Elasticsearch.

SSL/TLS encryption is disabled by default, which means user credentials are passed in the clear. Do not deploy to production without enabling encryption! For more information, see Encrypting Communications.
SSL/TLS加密默认是关闭的，意味着用户凭证是通过名文传递的。如果没有部署到生产上是不需要加密的！对于更多的信息，见加密通信。
You must also change the passwords for the built-in elastic user and the kibana user that enables Kibana to communicate with Elasticsearch before deploying to production. For more information, see Setting Up User Authentication.
你也必须改变内置elastic用户和kibana用户的密码来保证Kibana和Elasticsearch的通信在部署到生产环境之前。有关更多的信息，见设置用户权限。
Installing X-Pack on a DEB/RPM Package Installation
使用DEB/RPM安装包来安装X-Pack
If you use the DEB/RPM packages to install Elasticsearch, by default Elasticsearch is installed in /usr/share/elasticsearch and the configuration files are stored in /etc/elasticsearch. (For the complete list of default paths, see Debian Directory Layout and RPM Directory Layout in the Elasticsearch Reference.)
如果你使用DEB/RPM包来安装Elasticsearch，默认的Elasticsearch被安装到/usr/share/elasticsearch兵器配置文件被存储在/etc/elasticsearch中。（对于默认路径的完整清单，见Elasticsearch参考文档中有关Debian目录结构和RPM目录结构的相关内容）
To install X-Pack on a DEB/RPM package installation, you need to run bin/plugin install from the /usr/share/elasticsearch directory with superuser permissions:
为了在DEB/RPM包安装方式的前提下安装X-Pack，你需要运行/usr/share/elasticsearch目录中的bin/plugin install，但是要注意权限问题。
cd /usr/share/elasticsearch
sudo bin/elasticsearch-plugin install x-pack
Note
注意
If the configuration files are not in /etc/elasticsearch you need to specify the location of the configuration files by setting the system property es.path.conf to the config path via ES_JAVA_OPTS=”-Des.path.conf=” or by setting the environment variable CONF_DIR via CONF_DIR=.
如果配置文件不是在/etc/elasticsearch中，你需要指定配置文件的位置通过设置系统属性es.path.conf来配置路径通过ES_JAVA_OPTS="-Des.path.conf=或者设置环境变量" CONF_DIR通过CONF_DIR=。

General Machine Learning Settings
通用的机器学习设置
xpack.ml.enabled
Set to true (default) to enable machine learning. 设置为true（默认值）来启用机器学习。 If set to false in elasticsearch.yml, the machine learning APIs are disabled. You also cannot open jobs, start datafeeds, or receive transport (internal) communication requests related to machine learning APIs. It also affects all Kibana instances that connect to this Elasticsearch instance; you do not need to disable machine learning in those kibana.yml files. For more information about disabling machine learning in specific Kibana instances, see Kibana Machine Learning Settings. 如果在elasticsearch.yml中设置了false，机器学习的API是关闭的。你不能启动任务、启动datafeeds或接收传输（内部）通信请求依赖于机器学习的API，他也影响所有到所有连接到这个Elasticsearch实例的Kibana实例；你不需要关闭机器学习在kibana.yml文件中。对于更多有关在指定Kibana实例中关闭机器学习的方式，见[Kibana机器学习设置](https://www.elastic.co/guide/en/kibana/5.5/ml-settings-kb.html)
Important
重要
If you want to use machine learning features in your cluster, you must have xpack.ml.enabled set to true on all master-eligible nodes. This is the default behavior.
如果你希望使用机器学习特性在你的集群中，你必须设置xpack.ml.enable设置为true对于所有的主节点。这是默认的行为。
node.ml
Set to true (default) to identify the node as a machine learning node. 设置为true（默认值）来定义节点作为机器学习的学习节点 If set to false in elasticsearch.yml, the node cannot run jobs. If set to true but xpack.ml.enabled is set to false, the node.ml setting is ignored and the node cannot run jobs. If you want to run jobs, there must be at least one machine learning node in your cluster. 如果在elasticsearch.yml中设置为false，节点不能运行任务。如果设置为true但是xpack.xml.enabled是设置为ifalse，则node.ml的设置将被忽略并且节点不能运行任务，在你的集群中需要至少一个机器学习节点。
Important
重要
On dedicated coordinating nodes or dedicated master nodes, disable the node.ml role.
对于专用的协调节点或探测主节点，关闭了node.ml的角色。
