一.准备环境：
1.centos7 环境
2.安装ansible环境
3.elasticsearch安装文件下载路径：
https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.6.2-linux-x86_64.tar.gz
4.elasticsearch安装主机，作者用192.168.126.129作为elasticsearch安装环境
二.规划：
1.变量规划：
安装路径：elasticsearch_dir: "/kingdee/elasticsearch"
运行用户：es_start_user: elasticsearch
用户名称：esusername: logadmin
用户密码：espassword: Mytest@@@@@1203
监听端口：elasticsearch_port: 9200
最大内存(GB)： memory_max: 1
最小内存(GB)： memory_small: 1
2.mongodb目录规划：
安装目录：/kingdee/elasticsearch
三.编写ansible-playbook：
1.创建ansible-playbook剧本目录
mkdir -p roles/elasticsearch_single/{files,tasks,templates,vars}2.模板文件配置
cd roles/elasticsearch_single/templates
vim elasticsearch.yml.j2

- include_tasks: init.yml
- include_tasks: install_elasticsearch.yml3.拿取elsticsearch安装包
cd roles/elasticsearch_single/files
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.6.2-linux-x86_64.tar.gz -O elasticsearch-8.6.2-linux-x86_64.tar.gz
整个roles目录如下：
四.编写hosts文件，与roles文件在同级目录：
vim hosts
[elasticsearch]
ansible-master ansible_ssh_host=192.168.126.128
五.编写运行yml文件：
vim startinstall_single_elasticsearch.yml
---
- hosts: elasticsearch_single
remote_user: yzj
gather_facts: no
vars:
- es_start_user: elasticsearch
- esusername: logadmin
- espassword: Kingdee@1203
- elasticsearch_dir: "/kingdee/elasticsearch"
- memory_small: 1
- memory_max: 1
- elasticsearch_port: 9200
roles:
- role: elasticsearch_single六.运行elasticsearch安装脚本：
ansible-playbook -i hosts startinstall_single_elasticsearch.yml
七：访问elasticsearch查看状态：
curl http://192.168.126.129:9200/_cat/nodes?v --user logadmin:'Mytest@@@@@1203'
curl http://192.168.126.129:9200/_cat/health?v --user logadmin:'Mytest@@@@@1203'
至此，ansible-playbook部署elasticsearch单机部署已完成，下面会讲到elasticsearch[集群]使用ansible-playbook进行部署，如果对您有用，帮忙点个赞呗!
