1.安装主节点
1.去官网下载es的yum包 官网下载地址 https://www.elastic.co/cn/downloads/elasticsearch 根据自己的需要下载对应的包
2.下载好之后把所有的包都传到从节点上#xff0c;安装

4.写yml吧配置文件传送到 其他节点
[rootes ~]# cat 1.yml

[rootes ~]# cat 1.yml
[rootes ~]# cat 1.yml
---

5.运行playbook
[rootes ~]# ansible-playbook 1.yml PLAY [copy es] ***************************************************************************************************************************************************************************************************TASK [Gathering Facts] *******************************************************************************************************************************************************************************************

[rootes ~]# egrep ## -Xm /etc/elasticsearch/jvm.options
