ElasticSearch（十）：Elasticsearch集群配置

我本地虚拟机配置了两台centos机器，分别安装了elasticsearch6.4.0版本，IP分别为：192.168.56.12， 192.168.56.13

分别修改两个机器上Elasticsearch的配置文件:

文件位置：elasticsearch安装目录/elasticsearch-6.4.0/config/elasticsearch.yml

我本地配置文件位置：/usr/local/elasticsearch-6.4.0/config、elasticsearch,yml

192.168.56.12机器配置文件信息如下：

 # ======================== 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 -----------------------------------
 #
 # Set the bind address to a specific IP (IPv4 or IPv6):
 #
 network.host: 192.168.56.12
 #
 # Set a custom port for HTTP:
 #
 http.port: 9200
 #
 # 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]"]
 #
 discovery.zen.ping.unicast.hosts: ["192.168.56.12"]
 #
 # Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
 #
 #discovery.zen.minimum_master_nodes:
 #
 # 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
 http.cors.enabled: true
 http.cors.allow-origin: "*"

192.268.56.13机器配置文件信息如下：

这里两台机器的cluster.name必须一致 这样才算一个集群

node.name节点名称每台取不同的名称，用来表示不同的集群节点

network.host配置成自己的局域网IP

http.port端口就固定9200

discovery.zen.ping.unicast.hosts主动发现节点我们都配置成192.168.56.12节点IP

配置完后 重启es服务；

然后在head插件中查看：

访问正常，存在两个node节点，集群配置成功！
