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 7IP: 192.168.91.128port : 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IPnetwork.host: 192.168.91.128#启动的端口，默认9200 9200 #跨域设置true"*" #集群信息cluster.name: artisannode.name: masternode.master: true

其他配置，也可以按需修改

​Slave01：​

#host 和 端口network.host: 192.168.91.1288200#集群信息cluster.name: artisannode.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: 192.168.91.1287200#集群信息cluster.name: artisannode.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:# ---------------------------------- 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:#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true"*"#集群信息cluster.name: artisannode.name: masternode.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

[root@localhost ~]# su - elastic Last login: Thu Apr 18 08:47:46 PDT 2019 on pts/1[elastic@localhost ~]$ pwd/home/elastic[elastic@localhost ~]$ lltotal 33108drwxr-xr-x. 9 elastic elastic 4096 Apr 18 03:30 elasticsearch-5.6.16-rw-r--r--. 1 root root 33894983 Apr 18 03:27 elasticsearch-5.6.16.tar.gz[elastic@localhost ~]$ [elastic@localhost ~]$ [elastic@localhost ~]$ mkdir elasticsearch-5.6.16-salve[elastic@localhost ~]$ cp elasticsearch-5.6.16.tar.gz elasticsearch-5.6.16-salve/[elastic@localhost ~]$ cd elasticsearch-5.6.16-salve/[elastic@localhost elasticsearch-5.6.16-salve]$ lltotal 33104-rw-r--r--. 1 elastic elastic 33894983 Apr 18 18:28 elasticsearch-5.6.16.tar.gz[elastic@localhost elasticsearch-5.6.16-salve]$ tar -xvzf elasticsearch-5.6.16.tar.gz [elastic@localhost elasticsearch-5.6.16-salve]$ cp -r elasticsearch-5.6.16 elasticsearch-slave01[elastic@localhost elasticsearch-5.6.16-salve]$ cp -r elasticsearch-5.6.16 elasticsearch-slave02[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network.host: 192.168.91.1288200#集群信息cluster.name: artisannode.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"]

Slave2节点搭建

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

elasticsearch.yml 追加如下配置

#host 和 端口network.host: 192.168.91.1287200#集群信息cluster.name: artisannode.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

Windows 部署 ES集群

三个节点：

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IPnetwork.host: 127.0.0.1#启动的端口，默认9200 9200 #跨域设置true"*" #集群信息cluster.name: artisannode.name: masternode.master: true

​salve01:​

#host 和 端口network.host: 127.0.0.18200#集群信息cluster.name: artisannode.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"]

​slave02:​

#host 和 端口network.host: 127.0.0.17200#集群信息cluster.name: artisannode.name: slave02#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"]

启动服务

双击H:\elasticsearch-5.6.16-slave02\bin\elasticsearch.bat

通过head 插件查看 集群信息

配置OK

注意事项

found existing node {master}{xdHjXCdET_e7M0G_MYNiTQ}{WbXaI8HtRDCbFEzS8VtdIg}{127.0.0.1}{127.0.0.1:9300} with the same id but is a different node instance];

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。​
