1、创建集群所需要的目录

创建ES的挂载目录

 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="1">

 class="hljs-ln-code"> class="hljs-ln-line">mkdir -p /usr/local/elasticsearch_jiqun_3_node/node-{1..3}/{config,plugins,data,log}

class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="2">

 class="hljs-ln-code"> class="hljs-ln-line">  class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="3"> class="hljs-ln-code"> class="hljs-ln-line">chmod 777 /usr/local/elasticsearch_jiqun_3_node/node-{1..3}/{config,plugins,data,log}

class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}" onclick="hljs.signin(event)">

创建kibana的挂载目录

 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="1"> class="hljs-ln-code"> class="hljs-ln-line">mkdir -p /usr/local/elasticsearch_jiqun_3_node/kibana/config/
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="2"> class="hljs-ln-code"> class="hljs-ln-line"> 
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="3"> class="hljs-ln-code"> class="hljs-ln-line">chmod 777 /usr/local/elasticsearch_jiqun_3_node/kibana/config/ class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}" onclick="hljs.signin(event)">

2、修改Linux的句柄数

vim /etc/sysctl.conf class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}" onclick="hljs.signin(event)">

添加如下内容：（vm.max_map_count=655360）

接下来再关闭swap

swapoff -a class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}" onclick="hljs.signin(event)">

3、修改最大线程数

因为ES运行期间可能创建大量线程，如果线程数支持较少可能报错

vim /etc/security/limits.conf class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}" onclick="hljs.signin(event)">

 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="1"> class="hljs-ln-code"> class="hljs-ln-line"># 添加以下内容
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="2"> class="hljs-ln-code"> class="hljs-ln-line">* soft nofile 65536
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="3"> class="hljs-ln-code"> class="hljs-ln-line">* hard nofile 131072
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="4"> class="hljs-ln-code"> class="hljs-ln-line">* soft nproc 4096
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="5"> class="hljs-ln-code"> class="hljs-ln-line">* hard nproc 4096 class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}" onclick="hljs.signin(event)">

如下图

重启

reboot class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}" onclick="hljs.signin(event)">

4、添加IK分词器

首先需要下载IK分词器压缩包

下载方式1
链接: https://pan.baidu.com/s/1zxetPFZyRPyxwFFIL113DQ 提取码: 9m6a

下载方式2

在github中下载对应版本的分词器，网址：Releases · infinilabs/analysis-ik · GitHub

将下载的分词器复制到ES安装目录的plugins目录中并进行解压

 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="1"> class="hljs-ln-code"> class="hljs-ln-line">mkdir ik && cd ik
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="2"> class="hljs-ln-code"> class="hljs-ln-line">unzip elasticsearch-analysis-ik-7.17.5.zip class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}" onclick="hljs.signin(event)">

将这个ik目录分别添加到ES的三个节点的plugins目录里

 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="1"> class="hljs-ln-code"> class="hljs-ln-line">cp -R ik/ /usr/local/elasticsearch_jiqun_3_node/node-1/plugins/
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="2"> class="hljs-ln-code"> class="hljs-ln-line">cp -R ik/ /usr/local/elasticsearch_jiqun_3_node/node-2/plugins/
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="3"> class="hljs-ln-code"> class="hljs-ln-line">cp -R ik/ /usr/local/elasticsearch_jiqun_3_node/node-3/plugins/ class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}" onclick="hljs.signin(event)">

5、编写配置文件

node-1

vi /usr/local/elasticsearch_jiqun_3_node/node-1/config/elasticsearch.yml class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}" onclick="hljs.signin(event)">

启动服务

docker-compose up -d class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}" onclick="hljs.signin(event)">

7、测试集群

查询集群健康状态

GET /_cluster/health class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}" onclick="hljs.signin(event)">

status 字段是我们最关心的，status 字段指示着当前集群在总体上是否工作正常。它的三种颜色含义如下

green：所有的主分片和副本分片都正常运行
yellow：所有数据可用，但有些副本尚未分配(集群功能完全)
red：有主分片没能正常运行

创建索引测试

 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="1"> class="hljs-ln-code"> class="hljs-ln-line">PUT test
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="2"> class="hljs-ln-code"> class="hljs-ln-line">{
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="3"> class="hljs-ln-code"> class="hljs-ln-line">  "settings":{
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="4"> class="hljs-ln-code"> class="hljs-ln-line">    "index":{
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="5"> class="hljs-ln-code"> class="hljs-ln-line">      "number_of_shards" : "1",
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="6"> class="hljs-ln-code"> class="hljs-ln-line">      "number_of_replicas" : "0"
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="7"> class="hljs-ln-code"> class="hljs-ln-line">    }
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="8"> class="hljs-ln-code"> class="hljs-ln-line">  }
 class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="9"> class="hljs-ln-code"> class="hljs-ln-line">} class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}" onclick="hljs.signin(event)">

"number_of_shards" : "1"：指定索引的分片个数

"number_of_replicas" : "0"：指定每个分片的副本个数

注意：如果某一个节点上存储了分片及分片自身的副本，会导致什么现象

如上图所示我们看到多出一个Unassigned的副本，这个副本其实是多余的了，因为每个节点已经包含了分片的本身和其副本，多于这个没有意义！

并且因为多出来了一个副本无法分配，整个集群都变成了yellow的状态
