centos7.9 部署elasticsearch 7.17.8 集羣

準備基本環境

名稱	ip地址	cpu	內存	es監聽端口
redis-651	10.0.2.1	8c	64G	9200
redis-652	10.0.2.2	8c	64G	9200
redis-653	10.0.2.3	8c	64G	9200

搭建集羣

• 10.0.2.1 主機配置基本環境

# 更新hosts文件
cat /etc/hosts
10.0.2.1	es-node-1
10.0.2.2	es-node-2
10.0.2.3	es-node-3

# 創建es用戶
useradd -d /export/es  es
su - es

# 下載包並解壓
[es@es-node-1 ~]$ cd /export
[es@es-node-1 ~]$ wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.17.8-linux-x86_64.tar.gz
[es@es-node-1 ~]$ tar -xf elasticsearch-7.17.8-linux-x86_64.tar.gz

# 創建數據目錄並準備配置文件
[es@es-node-1 ~]$ mkdir /export/elasticsearch-7.17.8/data/
[es@es-node-1 ~]$ cd /export/elasticsearch-7.17.8/config/
[root@es-node-1 config]# vim elasticsearch.yml
