分發安裝檔案
scp -r elasticsearch-6.5.1 [email protected]:~/
scp -r elasticsearch-6.5.1 [email protected]:~/
修改cluster-slave1和cluster-backup配置檔案
cluster-slave1節點
vi elasticsearch.yml
node.name: node2
cluster-backup節點
vi elasticsearch.yml
node.name: node3
啟動
在三個節點分別執行
bin/elasticsearch &
配置elasticsearch-head
下載配置nodejs
wget https://nodejs.org/dist/v10.14.1/node-v10.14.1-linux-x64.tar.xz
tar -xvf node-v10.14.1-linux-x64.tar.xz

cd elasticsearch-head
npm install -g grunt-cli
npm install
grunt server
檢視elasticsearch-head web 控制檯
http://192.168.120.5:9100/
建立一個index，這裡使用的是google 瀏覽器的postman外掛；
這裡需要注意的是，雖然我們指定http://192.168.120.5:9200/customer?pretty傳送Put請求建立Index，其實只要指定叢集中任何一臺節點都可以
檢視叢集狀態
