docker、docker-compose部署elasticsearch集群

docker-compose部署elasticsearch集群

一、部署思路

模拟部署了六个节点，其中两个master节点，不做数据存储，四个data节点，用来存储数据

注意：

  1. 本文使用docker-compose进行部署，没有安装的先自行安装
  2. 本文的elasticsearch集群使用docker进行部署，开发学习环境中可以这么使用，在生产环境中还是不要这样部署，熟悉elasticsearch原理的就会清楚，单机部署elasticsearch集群基本无法起到什么作用。

二、配置文件

1、目录结构

      docker-compose.yml
      data
        es00
        es01
        es02
        es03
        es04
        es05
      config
        es00
          elasticsearch.yml
        es01
          elasticsearch.yml
        es02
          elasticsearch.yml
        es03
          elasticsearch.yml
        es04
          elasticsearch.yml
        es05
          elasticsearch.yml
      logs
        es00
        es01
        es02
        es03
        es04
        es05

2、docker-compose.yml

三、集群启动

1、启动

在docker-compose.yml文件目录下

docker-compose up -d

2、停止

docker-compose stop

3、如果启动后无法访问，查看日志排查问题（会有使用root用户无法启动es的问题，需要排查）

docker logs -f-t--tail=500 es01

无法启动的原因：

1、会有使用root用户无法启动es的问题，需要排查（新建系统用户启动es集群）

2、需要修改文件夹权限 chmod 777 -R [文件夹] （data、log、config 几个文件夹改权限）

三、集群安装分词器

6.1 进入docker容器

docker exec -it es01/bin/bash

6.2 下载安装分词器

./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.3.0/elasticsearch-analysis-ik-7.3.0.zip
