这里使用的是自己制作的安装了elasticsearch-analysis-ik-6.3.0插件的docker镜像。
在自己的osx系统上安装了docker后,已经有了docker-compose命令可用,在服务器上(CentOS系统)安装docker后发现没有docker-compose命令,需要单独再安装docker-compose,安装方式参考install-compose。
这里的docker-compose.yml按照官网的示例写的,部分地方做了点修改,如下:
version: '2.2'
services:
elasticsearch:
# image: docker.elastic.co/elasticsearch/elasticsearch:6.3.0
# 这里使用自己制作的安装了ik插件的镜像
image: elasticsearch-with-ik:6.3.0
container_name: elasticsearch
environment:
# 集群的名称,名称一样的组成一个集群
- cluster.name=docker-es-cluster
- bootstrap.memory_lock=true
- "ES_JAVA_OPTS=-Xms512m -Xmx512m"
# 设置允许跨域,方便head插件访问
- "http.cors.enabled=true"
- "http.cors.allow-origin=*"
# 这里的elasticsearch,elasticsearch2,elasticsearch3是指的设置的container_name,容器内部可以通过container_name相互网络访问
- "discovery.zen.ping.unicast.hosts=elasticsearch,elasticsearch2,elasticsearch3"
- node.name=elasticsearch

执行docker-compose up启动,这里配置了三个实例,映射出来的端口分别是9200、9201、9202。这里遇到一个问题,在我的osx系统上一开始始终只能启动两个实例,会随机失败一个(有时候是elasticsearch失败,有时候是elasticsearch2失败,有时候是elasticsearch3失败),错误信息是exited with code 137。通过搜索发现是内存设置太小所致 ,将内存改大即可
修改内存大小
通过head插件可以看到集群相关信息
连接9200 连接9201
集群状态
