1.下載軟件包

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.8.10.tar.gz

2.創(chuàng)建用戶

useradd -m -d /home/es -s /bin/bash es

3.解壓并修改屬性信息

tar xf elasticsearch-6.8.10.tar.gz -C /home/es/
chown -R es:es /home/es/

4.創(chuàng)建相關(guān)目錄并修改屬性信息

mkdir -pv /es/{data,logs,tmp}
chown -R es:es /es

5.修改主機(jī)解析

echo '172.21.149.8 bj-p-es003
172.21.149.9 bj-p-es002
172.21.149.10 bj-p-es001' >> /etc/hosts

6.修改配置文件

vim  /home/es/elasticsearch-6.8.10/config/elasticsearch.yml
cluster.name: es-data
node.name: bj-p-es002
path:
  data: /es/data
  logs: /es/logs
network.host: 0.0.0.0
http.port: 9200
discovery.zen.minimum_master_nodes:
   - 172.21.149.10
   - 172.21.149.9
   - 172.21.149.8
discovery.zen.minimum_master_nodes: 2
node.master: true
node.data: true
node.ingest: true

注意修改集名稱及節(jié)點(diǎn)名稱

7.添加環(huán)境變量

export JAVA_HOME=/usr/local/java
export PATH=$PATH:$JAVA_HOME/bin
export ES_HOME="/home/es/elasticsearch-6.8.10"
export ES_JAVA_HOME="${JAVA_HOME}"
export ES_TMPDIR="/es/tmp"

8.修改內(nèi)核參數(shù)

vim /etc/sysctl.conf
vm.max_map_count = 262144

9.啟動(dòng)es并測(cè)試

su - es
./elasticsearch-6.8.10/bin/elasticsearch -d
curl http://127.0.0.1:9200/_cat/nodes
curl http://127.0.0.1:9200
