CentOs 7.4下使用Docker容器搭建Elasticsearch集羣

• 拉取Elcasticsearch鏡像

docker pull elasticsearch:5.6.8

• 調高JVM線程數

#編輯
vim /etc/sysctl.conf

#加入內容
vm.max_map_count=262144 

#啓用配置
sysctl -p

• 新建ES01節點配置文件es01.yml

#ES01配置
cluster.name: elasticsearch-cluster
node.name: es-node-01
network.bind_host: 0.0.0.0
network.publish_host: 192.168.44.113
http.port: 9200
transport.tcp.port: 9300
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
node.data: true
discovery.zen.ping.unicast.hosts: ["192.168.44.113:9300","192.168.44.113:9301","192.168.44.113:9302"]
discovery.zen.minimum_master_nodes: 2

• 新建ES02節點配置文件es02.yml

#ES02配置
cluster.name: elasticsearch-cluster
node.name: es-node-02
network.bind_host: 0.0.0.0
network.publish_host: 192.168.44.113
http.port: 9201
transport.tcp.port: 9301
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true

discovery.zen.minimum_master_nodes: 2

• 新建ES03節點配置文件es03.yml

#ES03配置
cluster.name: elasticsearch-cluster
node.name: es-node-03
network.bind_host: 0.0.0.0
network.publish_host: 192.168.44.113
http.port: 9202
transport.tcp.port: 9302
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
node.data: true
discovery.zen.ping.unicast.hosts: ["192.168.44.113:9300","192.168.44.113:9301","192.168.44.113:9302"]
discovery.zen.minimum_master_nodes: 2

• 分別啓動三臺節點

docker run -e ES_JAVA_OPTS="-Xms512m -Xmx512m" -p 9200:9200 -p 9300:9300 -v /opt/es/es01.yml:/usr/share/elasticsearch/config/elasticsearch.yml --name ES01 -d 6c0bdf761f3b
docker run -e ES_JAVA_OPTS="-Xms512m -Xmx512m" -p 9201:9201 -p 9301:9301 -v /opt/es/es02.yml:/usr/share/elasticsearch/config/elasticsearch.yml --name ES02 -d 6c0bdf761f3b
docker run -e ES_JAVA_OPTS="-Xms512m -Xmx512m" -p 9202:9202 -p 9302:9302 -v /opt/es/es03.yml:/usr/share/elasticsearch/config/elasticsearch.yml --name ES03 -d 6c0bdf761f3b

• 測試是否搭建成功

http://192.168.44.113:9200/_cat/nodes?pretty

• 配置IK中文分詞器
  • 資源鏈接：https://pan.baidu.com/s/1c6av35dAbP-EZCiARf_ujA 提取碼：2868
  • 上傳elasticsearch-analysis-ik-5.6.8.zip至服務器
    
  • 解壓至指定位置

   unzip elasticsearch-analysis-ik-5.6.8.zip -d /opt/module/
  

  • 拷貝ik-analyzer至ES容器中

  #分貝爲ES節點配置ik-分詞器
  docker cp /opt/module/ik-analyzer  b8bc77952780:/usr/share/elasticsearch/plugins/
  docker cp /opt/module/ik-analyzer  17fc09305869:/usr/share/elasticsearch/plugins/
  docker cp /opt/module/ik-analyzer  07ece64fc7d8:/usr/share/elasticsearch/plugins/
  

  • 重新啓動ES集羣

  docker restart b8bc77952780 17fc09305869 07ece64fc7d8
  

  • 測試ik分詞效果

• 拉取ES UI鏡像

#拉取
docker pull mobz/elasticsearch-head:5

• 啓動ES UI鏡像

#啓動
docker run -p 9520:9100 --name es-ui -d b19a5c98e43b

• 訪問ES的UI工具並鏈接ES集羣

#UI地址
