ElasticSearch是一个基于Lucene的搜索服务器。它提供了一个分布式多用户能力的全文搜索引擎。
ElasticSearch安装包下载
到ElasticSearch官网 对应版本的安装包，本文以ElasticSearch 6.5.4为例。
将下载好的elasticsearch-6.5.0.tar.gz传到/opt/ansible/roles/files目录下，本文将所有tar安装包都进行了重命名操作，比如将elasticsearch-6.5.0.tar.gz解压后重命名为elasticsearch并打成elasticsearch.tar.gz包。
编写主机hosts
编辑/opt/ansible/hosts文件添加部署Kafka机器IP
[es_servers]
172.18.18.120
172.18.18.121
172.18.18.122
编写ElasticSearch配置文件
将elasticsearch-6.5.0.tar.gz解压后的配置文件elasticsearch.yml和elasticsearch.in.sh修改成自己的配置并重命名为elasticsearch.yml.j2和elasticsearch.in.sh.j2，然后上传到/opt/ansible/roles/templates/ 目录下。由于配置文件较多，本文不进行展示。
编写参数配置main.yml
编辑/opt/ansible/roles/vars/main.yml文件，添加变量
BigdataDir: /opt/hzgc
AnsibleDir: /opt/ansible
编写执行文件elasticsearch.yml
