1、獲取安裝包，並解壓 wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.1.1.tar.gz tar -zxvf elasticsearch-6.1.1.tar.gz ln -s elasticsearch-6.1.1 elasticsearch   2、配置，進入config目錄 1)配置elasticsearch.yml 建立data目錄：索引資料的儲存路徑 建立logs目錄：日誌檔案的儲存路徑 配置資訊如下： cluster.name: my-application #叢集的名稱 node.name: master #節點名稱,其餘兩個節點分別為slave1和slave2 path.data: /usr/local/src/elasticsearch/elasticsearch/data #索引資料的儲存路徑 path.logs: /usr/local/src/elasticsearch/elasticsearch/logs #日誌檔案的儲存路徑 bootstrap.memory_lock: true #設定為true來鎖住記憶體。因為記憶體交換到磁碟對伺服器效能來說是致命的，當jvm開始swapping時es的效率會降低，所以要保證它不swap network.host: 172.16.209.10 #繫結的ip地址 ，其他節點也應該為對應的IP地址 http.port: 9200 #設定對外服務的http埠，預設為9200 discovery.zen.ping.unicast.hosts: ["172.16.209.10", "172.16.209.11", "172.16.209.12"] #叢集IP地址 discovery.zen.minimum_master_nodes: 2 #為了避免腦裂，叢集節點數最少為半數+1   2）配置 jvm.options檔案 # Xms represents the initial size of total heap space ，即初始時，java堆空間大小 # Xmx represents the maximum size of total heap space ，最大堆空間大小 -Xms64m -Xmx256m   3) log4j2.properties日誌格式配置檔案，暫時不用改   3、將安裝包傳送給slave1和slave2 scp -r elasticsearch/

[email protected]:/usr/local/src scp -r elasticsearch/ [email protected]:/usr/local/src 並修改elasticsearch.yml 配置檔案中的node.name 和 network.host屬性   4、配置elasticsearch環境變數 配置三臺叢集的環境變數,vi /etc/profile 增加： export ES_HOME=/usr/local/src/elasticsearch/elasticsearch export PATH=$PATH:$ES_HOME/bin: 然後執行： source /etc/profile 生效   5、啟動elasticsearch 輸入./elasticsearch 啟動，但是報錯 [
