由於資源有限，使用是一台機器上安裝三個elasticSearch服務端組成的集群。
1. 安裝elasticSearch6.3.2
將原本安裝的elasticSearch6.3.2復制兩份，分別重新命名，如下：
2. 修改配置文件
進入elasticSearch的config目錄，打開 elasticsearch.yml文件，修改如下信息：
需要注意的是：
默認所有節點都會存儲數據。
如果你是一台機器上多個es服務器，那么必須指定不同的tcp端口。
# ======================== 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: 集群名，其余節點都是通過這個名字來找到集群 cluster.name: zskj # # ------------------------------------ Node ------------------------------------ # Use a descriptive name for the node: # 節點名 node.name: node # # 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 ----------------------------------- # # Set the bind address to a specific IP (IPv4 or IPv6): # 節點的ip地址 network.host: 127.0.0.1 # # Set a custom port for HTTP: # 端口 http.port: 9200 # tcp端口。 transport.tcp.port: 9300 # # For more information, consult the network module documentation. # # --------------------------------- Discovery ---------------------------------- # # Pass an initial list of hosts to perform discovery when new node is started: # The default list of hosts is ["127.0.0.1", "[::1]"] # elasticSearch集群的地址。這里使用的是一台機器的不同端口。 discovery.zen.ping.unicast.hosts: ["127.0.0.1:9300", "127.0.0.1:9301", "127.0.0.1:9302"] # # Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1): # 預防腦裂，建議為總集群數一半 + 1 discovery.zen.minimum_master_nodes: 2 # # For more information, consult the zen discovery module documentation. # # ---------------------------------- Gateway ----------------------------------- # # Block initial recovery after a full cluster restart until N nodes are started: # #gateway.recover_after_nodes: 3 # # For more information, consult the gateway module documentation. # # ---------------------------------- Various ----------------------------------- # # Require explicit names when deleting indices: # #action.destructive_requires_name: true # 跨域 http.cors.enabled: true http.cors.allow-origin: "*"
需要特別注意的是：
1. 如果你的elasticSearch節點在 elasticsearch.yml中添加了中文之后，導致elasticSearch無法啟動，就必須把yml文件中的中文刪除，然后就可以重啟啟動了。報錯信息如下：
2. 配置文件書寫的時候需要注意：屬性必須定格寫，之后是一個“：”，之后空格，然后是屬性值。不能使用tab鍵。
3. 啟動集群
分別啟動三個elasticSearch節點即可啟動集群。
4. 一個小的技巧
如果你也是和我一樣，使用的是一台機器的三個elasticSearch服務端，每次都需要點到文件中，點擊elasticsearch.bat，確實挺麻煩，那么你可以試試批處理。
右鍵創建一個文件，命名為xxxx.bat即可。使用記事本打開，然后寫入如下命令，保存即可。
@echo off title ES集群啟動工具 REM 切換命令行目錄為當前BAT所在目錄 cd /d E:\ElasticSearch\elasticsearch-6.3.2\bin start elasticsearch.bat echo elasticsearch1正在啟動。。。 cd /d E:\ElasticSearch\elasticsearch-6.3.2_02\bin start elasticsearch.bat echo elasticsearch2正在啟動。。。 cd /d E:\ElasticSearch\elasticsearch-6.3.2_03\bin start elasticsearch.bat echo elasticsearch3正在啟動。。。
作用就是：分別自動切換到三個elasticSearch的目錄，然后自動點擊 elasticsearch.bat，啟動服務端。
如果你還安裝了head插件，每次點開啟動也挺麻煩，可以直接在批處理后面添加語句即可：當elasticSearch服務端完全啟動之后，點擊任意鍵啟動head插件
echo 任意鍵繼續啟動head插件 pause cd /d E:\ElasticSearch\head call grunt server
綜上：你只需要雙擊你的批處理工具 xxxx.bat就可以完成集群的啟動了，如果你在多台服務器上，那么還是一個一個啟動吧。
