Linux中使用Docker搭建ElasticSearch集群

1. 拉取镜像

docker pull elasticsearch:6.5.4

2. 先创建本地容器映射目录方便管理，我的目录结构

+ haoke
  + es-cluster
    + node01
    	+ data
    	+ elasticsearch.yml
    	+ jvm.options
    + node02
    	+ data
    	+ elasticsearch.yml
    	+ jvm.options
    + node03
    	+ data
    	+ elasticsearch.yml
    	+ jvm.options
    + ik          // IK分词
    + pinyin      // 拼音分词

3. 分词器上传(非必须)

上传ik分词器和pinyin分词器并解压到对应文件夹

unzip elasticsearch-analysis-ik-6.5.4.zip  /haoke/es-cluster/ik/

unzip elasticsearch-analysis-pinyin-6.5.4.zip /haoke/es-cluster/pinyin/

4. 配置文件

node01的elasticsearch.yml

# 集群名称
cluster.name: es-itcast-cluster
# 节点名称
node.name: node01
node.master: true
node.data: true
truenetwork.host: 192.168.134.128
http.port: 9200
discovery.zen.ping.unicast.hosts: ["192.168.134.128"]

# 设置minimum_master_nodes的大小为2，官方推荐：(N/2)+1，N为集群中节点数
discovery.zen.minimum_master_nodes: 2 

# 跨域（非必须）
http.cors.enabled: true
http.cors.allow-origin: "*"

node02的elasticsearch.yml

cluster.name: es-itcast-cluster
node.name: node02
node.master: true
node.data: true
truenetwork.host: 192.168.134.128
http.port: 9201
discovery.zen.ping.unicast.hosts: ["192.168.134.128"]
discovery.zen.minimum_master_nodes: 2
http.cors.enabled: true
http.cors.allow-origin: "*"

node03的elasticsearch.yml

cluster.name: es-itcast-cluster
node.name: node03
node.master: true
node.data: true
truenetwork.host: 192.168.134.128
http.port: 9202
discovery.zen.ping.unicast.hosts: ["192.168.134.128"]
discovery.zen.minimum_master_nodes: 2
http.cors.enabled: true
http.cors.allow-origin: "*"

node01、node02、node03的jvm.options

-Xms256m
-Xmx256m

5. 容器创建，设置net为host设置与虚拟机同一个IP

创建容器node01

docker create --name es-node01 --net host 
-v /haoke/es-cluster/node01/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml 
-v /haoke/es-cluster/node01/jvm.options:/usr/share/elasticsearch/config/jvm.options 
-v /haoke/es-cluster/ik:/usr/share/elasticsearch/plugins/ik 
-v /haoke/es-cluster/pinyin:/usr/share/elasticsearch/plugins/pinyin 
-v /haoke/es-cluster/node01/data:/usr/share/elasticsearch/data elasticsearch:6.5.4

创建容器node02

docker create --name es-node02 --net host 
-v /haoke/es-cluster/node02/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml 
-v /haoke/es-cluster/node02/jvm.options:/usr/share/elasticsearch/config/jvm.options 
-v /haoke/es-cluster/ik:/usr/share/elasticsearch/plugins/ik 
-v /haoke/es-cluster/pinyin:/usr/share/elasticsearch/plugins/pinyin 
-v /haoke/es-cluster/node02/data:/usr/share/elasticsearch/data elasticsearch:6.5.4

创建容器node03

docker create --name es-node03 --net host 
-v /haoke/es-cluster/node03/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml 
-v /haoke/es-cluster/node03/jvm.options:/usr/share/elasticsearch/config/jvm.options 
-v /haoke/es-cluster/ik:/usr/share/elasticsearch/plugins/ik 
-v /haoke/es-cluster/pinyin:/usr/share/elasticsearch/plugins/pinyin 
-v /haoke/es-cluster/node03/data:/usr/share/elasticsearch/data elasticsearch:6.5.4

6. 启动容器，并查看日志

docker start es-node01 && docker logs -f es-node01 

docker start es-node02 && docker logs -f es-node02

docker start es-node03 && docker logs -f es-node03
