最近有同学留言，关于Kafka Eagle的一些使用问题。今天笔者就为大家来详细介绍Kafka Eagle 3.0.1的功能以及使用方法。

2.内容

在3.0.1版本中，EFAK优化了分布式模式的服务性能，减少了磁盘IO和网络IO的操作次数，提升了内存和CPU的使用率。下面，我们就来看看3.0.1的相关功能。

2.1 基础环境

部署EFAK所需要的基础环境如下：

2.2.1 硬件和操作系统

操作系统：Linux系统即可（Ubuntu、CentOS等）
JDK：JDK8以上
CPU：1核以上
内存：2GB以上

2.2.2 EFAK安装包

EFAK安装包，目前官网上以及发布了最新的v3.0.1版本，支持分布式模式部署。可以直接下载到Linux服务器进行安装和部署使用。如果需要自行编译部署，可以到Github下载源代码进行编译部署：

方式一：官网下载v2.0.9安装包
方式二：Github下载源代码，参考README说明进行编译

2.2 安装部署

2.2.3 配置EFAK系统文件
