Ambari搭建

Ambari简介

Apache Ambari是一种基于Web的工具，支持Apache Hadoop集群的供应、管理和监控。Ambari已支持大多数Hadoop组件，包括HDFS、MapReduce、Hive、Pig、 Hbase、Zookeeper、Sqoop和Hcatalog等。
Apache Ambari 支持HDFS、MapReduce、Hive、Pig、Hbase、Zookeepr、Sqoop和Hcatalog等的集中管理。也是5个顶级hadoop管理工具之一。

Ambari 跟 Hadoop 等开源软件一样，也是 Apache Software Foundation 中的一个项目，并且是顶级项目。2018年11月为止最新的发布版本是 2.7.3。就 Ambari 的作用来说，就是创建、管理、监视 Hadoop 的集群，但是这里的 Hadoop 是广义，指的是 Hadoop 整个生态圈（例如 Hive，Hbase，Sqoop，Zookeeper 等），而并不仅是特指 Hadoop。用一句话来说，Ambari 就是为了让 Hadoop 以及相关的大数据软件更容易使用的一个工具

系统环境

系统： CentOS-7.5_x64
MySQL: mysql-5.7.23_x64
