概述

Elasticsearch-01CentOS7单节点部署ES5.6.16中我们学习了ES单节点的部署，这里我们来看下ES集群是如何部署的吧

CentOS上部署ES集群

集群组成

节点数量： 3个（1个Master 2个Slave）
OS: CentOS 7
IP: 192.168.91.128
port : master-9200 slave01-8200 slave02-7200

方便起见，先按照伪集群模式部署吧，在同一台主机上使用不同的端口来区分不同的节点，当然了你也可以使用3台虚机,那是最好不过的了

关键配置信息

必须保证集群名相同，如果节点处于同一局域网同一网段，es会自动去发现其他的节点。

elasticsearch.yml

Master


# 绑定的服务器IP，可设置为本机IP
network.host: 192.168.91.128
#启动的端口，默认9200  
http.port: 9200
 
#跨域设置
http.cors.enabled: true
http.cors.allow-origin: "*"
 
#集群信息
cluster.name: artisan
node.name: master
node.master: true

其他配置，也可以按需修改

Slave01：

#host 和 端口
network.host: 192.168.91.128
http.port: 8200

#集群信息
cluster.name: artisan
node.name: slave01
#默认的通讯接口是9300,用来发现master信息
discovery.zen.ping.unicast.hosts: ["192.168.91.128:9300"]

Slave02:

#host 和 端口
network.host: 192.168.91.128
http.port: 7200

#集群信息
cluster.name: artisan
node.name: slave02
#默认的通讯接口是9300,用来发现master信息
discovery.zen.ping.unicast.hosts: ["192.168.91.128:9300"]

Master节点搭建

修改elasticsearch.yml中的配置

# ======================== 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: 192.168.91.128
#
# 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: ["host1", "host2"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes: 3
#
# 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
#
#跨域设置
http.cors.enabled: true
http.cors.allow-origin: "*"
#集群信息
cluster.name: artisan
node.name: master
node.master: true

通过head插件访问集群信息

可以看到节点名字已经变成了master, 并且前面的五角星表示为master节点（指挥官）。

Slave1节点搭建

复制一份，然后修改配置文件

[elastic@localhost elasticsearch-5.6.16-salve]$ cd elasticsearch-slave01

[elastic@localhost elasticsearch-slave01]$ vim config/elasticsearch.yml

elasticsearch.yml 追加如下配置

#host 和 端口

http.port: 8200

#集群信息
cluster.name: artisan
node.name: slave01
#默认的通讯接口是9300,找到集群的信
discovery.zen.ping.unicast.hosts: ["192.168.91.128:9300"]

[elastic@localhost elasticsearch-5.6.16-salve]$ cd elasticsearch-slave02

elasticsearch.yml 追加如下配置

#host 和 端口

node.name: slave02
#默认的通讯接口是9300,用来发现master信息
discovery.zen.ping.unicast.hosts: ["192.168.91.128:9300"]

我这里用的虚机的内存太小了，无法启动两个及两个以上的节点, 为了验证配置的正确性，windows上部署下吧

elasticsearch.yml配置修改

elasticsearch.yml的配置如下：

和centos中的配置一样，仅仅是IP不同

master:

# 绑定的服务器IP，可设置为本机IP
network.host: 127.0.0.1
#启动的端口，默认9200  
http.port: 9200
 
#跨域设置
http.cors.enabled: true
http.cors.allow-origin: "*"
 
#集群信息
cluster.name: artisan
node.name: master
node.master: true

salve01:

#host 和 端口
network.host: 127.0.0.1
http.port: 8200

#集群信息
cluster.name: artisan
node.name: slave01
#默认的通讯接口是9300,用来发现master信息
discovery.zen.ping.unicast.hosts: ["127.0.0.1:9300"]

注意事项

如果配到了这种错误，很明显id重复了，如果配置没有问题，看下你是不是直接copy的已经存在的节点data目录中的数据重复导致的。 建议解压一个新的压缩包，重新配置，避免上述错误。
