elasticsearch 6.2.4和elasticsearch-head环境搭建 使用docker-compose方式
elasticsearch 6.2.4和elasticsearch-head测试环境搭建 使用docker-compose方式
一 背景说明
对于新手来说搭建一个elasticsearch的测试环境稍微费力，而且没必须要去下载那么多安装包，比如java node npm等，所以我决定做成docker-compose方式的启动，并且集成ik分词器，方便快捷，一键搞定。
二 环境需求
你电脑需要安装docker和docker-compose
三 使用步骤
1 目录结构
.
├── docker-compose-elastic.yml
└── elasticsearch.yml
elasticsearch.yml
先编写elasticsearch的配置文件，后续是需要挂载到docker容器中的
elasticsearch.yml的内容如下：
network.bind_host: 0.0.0.0
cluster.name: elastic-cluster
network.host: 0.0.0.0
discovery.zen.minimum_master_nodes: 1
bootstrap.memory_lock: true
discovery.type: single-node
http.cors.enabled: true
http.cors.allow-origin: "*"
xpack.security.enabled: false
docker-compose-elastic.yml
docker-compose-elastic.yml 这里docker-compose需要的配置文件
elasticsearch.yml的内容如下：
version: '2'
services:
elastic:
image: bachue/elasticsearch-ik:6.2.4
container_name: elastic
environment:
- TZ='Asia/Shanghai'
- "ES_JAVA_OPTS=-Xms512m -Xmx512m"
ulimits:
memlock:
soft: -1
hard: -1
mem_limit: 1g
volumes:
- ./elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
- ./data:/usr/share/elasticsearch/data
ports:
- 9200:9200
- 9300:9300
elasticsearch-head:
image: wallbase/elasticsearch-head:6-alpine
container_name: elasticsearch-head
environment:
TZ: 'Asia/Shanghai'
ports:
- '9100:9100'
docker-compose配置说明
bachue/elasticsearch-ik:6.2.4 表示是带有ik分词的，不需要额外自己安装，
volumes 配置项主要是把本地文件挂载到容器中，包含配置文件和数据目录，data是数据目录，如果你只是测试，也可以不需要，但是你下次启动数据就丢失了。
wallbase/elasticsearch-head:6-alpine 从5.0之后head插件可以独立启动，我重新打包一个支持6.2.x版本的docker镜像上传的hub.docker.com中的。
四 启动
启动elasticsearch和elasticsearch-head,参数-d表示后台启动，当然你需要交互式启动可以把-d去掉,elasticsearch端口是9200,head插件的访问端口是9100

如上，es报错
