前期準備
JAVA環境
lasticsearch至少需要Java 8.具體到撰寫本文時，為了更加适配新版ElasticSearch，建議大家使用Oracle JDK版本1.8.0以上。Java安裝因平台而異，是以我們不會在此處詳細介紹。可以在Oracle的網站上找到Oracle推薦的安裝文檔。
首先，在安裝Elasticsearch之前 先看一下 是否安裝過JDK，以及JDK版本是否符合這次安裝（然後根據需要進行相應的安裝/更新）：
ElasticSearch安裝
下載下傳Elasticsearch
設定好Java，我們就可以下載下傳并運作Elasticsearch。二進制檔案可以https://www.elastic.co/downloads/elasticsearch與過去釋出的所有版本一起提供。對于每個版本，您可以選擇zip或tar存檔，包DEB或RPM包，或Windows MSI安裝包。

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
# Before you set out to tweak and tune the configuration, make sure you
# understand what are you trying to accomplish and the consequences.
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
# ---------------------------------- Cluster -----------------------------------
# Use a descriptive name for your cluster:
cluster.name: my-application
# ------------------------------------ Node ------------------------------------
# Use a descriptive name for the node:
node.name: node-1
# Add custom attributes to the node:
#node.attr.rack: r1
# ----------------------------------- Paths ------------------------------------
# Path to directory where to store the data (separate multiple locations by comma):
#path.data: /path/to/data
# Path to log files:
#path.logs: /path/to/logs
# ----------------------------------- Memory -----------------------------------
# Lock the memory on startup:
#bootstrap.memory_lock: true
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
# Elasticsearch performs poorly when the system is swapping the memory.
# ---------------------------------- Network -----------------------------------
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
network.host: 127.0.0.1
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
http.port: 9200
# For more information, consult the network module documentation.
# --------------------------------- Discovery ----------------------------------
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
discovery.seed_hosts: ["127.0.0.1"]
# Bootstrap the cluster using an initial set of master-eligible nodes:
cluster.initial_master_nodes: ["node-1"]
# For more information, consult the discovery and cluster formation module documentation.
# ---------------------------------- Various -----------------------------------
# Require explicit names when deleting indices:
#action.destructive_requires_name: true
# 設定證書
xpack.license.self_generated.type: basic
xpack.security.enabled: false
#是否支援跨域，預設為false
http.cors.enabled: true
#當設定允許跨域，預設為*,表示支援所有域名，如果我們隻是允許某些網站能通路，那麼可以使用正規表達式。比如隻允許本地位址。 /https?:\/\/localhost(:[0-9]+)?/
http.cors.allow-origin: "*"
#這是為elasticsearch增加自動建立索引功能
action.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history*,test_*
啟動
如果一切順利安裝，你應該看到一堆如下所示的消息：
