ElasticSearch安裝系列教程---->(四)、docker 搭建elasticsearch集羣

 

 

一、拉去es鏡像

docker pull docker.io/elasticsearch:5.6.8

 

二、 建立掛載目錄

mkdir -p /docker/es/config

mkdir -p /docker/es/data1

mkdir -p /docker/es/data2

mkdir -p /docker/es/data3

 

三、建立配置文件

touch /docker/es/config/es1.yml

touch /docker/es/config/es2.yml

touch /docker/es/config/es3.yml

 

四、修改配置文件

es1.yml文件內容爲：

cluster.name: elasticsearch-cluster

node.name: es-node1

network.bind_host: 0.0.0.0

network.publish_host: 192.168.100.102

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: ["192.168.100.102:9300","192.168.100.102:9301","192.168.100.102:9302"]

discovery.zen.minimum_master_nodes: 2

 

es2.yml文件內容爲：

cluster.name: elasticsearch-cluster

node.name: es-node2

network.bind_host: 0.0.0.0

network.publish_host: 192.168.100.102
http.port: 9201

transport.tcp.port: 9301

http.cors.enabled: true

http.cors.allow-origin: "*"

node.master: true

node.data: true

discovery.zen.ping.unicast.hosts: ["192.168.100.102:9300","192.168.100.102:9301","192.168.100.102:9302"]

discovery.zen.minimum_master_nodes: 2

es3.yml文件內容爲：

 

cluster.name: elasticsearch-cluster

node.name: es-node3

network.bind_host: 0.0.0.0

network.publish_host: 192.168.100.102

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: ["192.168.100.102:9300","192.168.100.102:9301","192.168.100.102:9302"]

discovery.zen.minimum_master_nodes: 2

 

五、修改系統參數

在   /etc/sysctl.conf文件最後添加一行 

vm.max_map_count=262144

執行下面命令

sysctl -w vm.max_map_count=262144

六、啓動節點

 

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9200:9200 -p 9300:9300 --privileged=true -v /docker/es/config/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /docker/es/data1:/usr/share/elasticsearch/data --name es-node1 elasticsearch:5.6.8

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9201:9201 -p 9301:9301 --privileged=true -v /docker/es/config/es2.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /docker/es/data2:/usr/share/elasticsearch/data --name es-node2 elasticsearch:5.6.8

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9202:9202 -p 9302:9302 --privileged=true -v /docker/es/config/es3.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /docker/es/data3:/usr/share/elasticsearch/data --name es-node3 elasticsearch:5.6.8

 

七、安裝es-head插件

docker pull mobz/elasticsearch-head:5

docker run -di --name=es-head -p 9100:9100 docker.io/mobz/elasticsearch-head:5

八、安裝ik分詞器

下載分詞器插件：https://github.com/medcl/elasticsearch-analysis-ik/releases/tag/v5.6.8

在宿主機解壓

unzip elasticsearch-analysis-ik-5.6.8.zip

並改文件夾名爲ik

mv elasticsearch ik

複製解壓後的ik到docker鏡像目錄

docker cp ik es-node1:/usr/share/elasticsearch/plugins

九、重啓容器

docker restart 容器id

 

十、單點運行

若是要單點運行 ，能夠把es-node2 es-node3 停掉 而且註釋掉es1.yml配置文件中的部分配置

cluster.name: elasticsearch-cluster
node.name: es-node1
network.bind_host: 0.0.0.0
http.port: 9200
transport.tcp.port: 9300
http.cors.enabled: true
http.cors.allow-origin: "*"
node.data: true
#network.publish_host: 192.168.100.102
#node.master: true 
#discovery.zen.ping.unicast.hosts: ["192.168.100.102:9300","192.168.100.102:9301","192.168.100.102:9302"]
#discovery.zen.minimum_master_nodes: 2

十一、安裝kibana

docker run -it -d -e ELASTICSEARCH_URL=http://172.17.0.2:9200 --name kibana -p 5601:5601 kibana:5.6.8

es 的 URL要寫容器內部的ip，查看容器內部的ip命令

docker inspect <container id>
