Wazuh的基本部署

本次将部署一套分布式Wazuh方案，实现其基本功能。其中：

1. wazuh-master启用全功能组件；
2. ElasticStack将使用官方基本授权，不启用X-pack和加密连接；
3. Linux版本Agent将安装到Kibana主机和ElasticSearch主机上，不再额外安装示例主机；
4. 各个功能组件采用单节点部署；
5. Wazuh使用4.1.5版本，搭配官方指定7.11.2ElasticStack版本。

部署方案

1. 部署拓扑

   

2. 网络地址

   系统角色	版本	网络地址
   ElasticSearch	7.11.2	192.168.248.146
   Kibana	7.11.2	192.168.248.145
   WazuhMaster	4.1.5	192.168.248.150
   WazuhAgent	4.1.5	192.168.248.1
