本文详细介绍如何使用Apache Ambari进行Hadoop集群的安装、配置及监控。通过步骤化的指导，帮助读者理解Ambari Server的安装过程，并提供解决常见问题的方法。

Hadoop 管理监控工具 Apache Ambari



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目前已支持大多数Hadoop组件，包括HDFS、MapReduce、Hive、Pig、 Hbase、Zookeper、Sqoop和Hcatalog等。

Apache Ambari 支持HDFS、MapReduce、Hive、Pig、Hbase、Zookeper、Sqoop和Hcatalog等的集中管理。也是5个顶级hadoop管理工具之一。

Step1: Download the Ambari repository on the Ambari Server host

[root@jifeng02 ~]# cd /etc/yum.repos.d/
Choose an appropriate <ambari-repo-url> based on the platform used: 
[root@jifeng02 yum.repos.d]# wget http://public-repo-1.hortonworks.com/ambari/centos6/1.x/updates/1.6.1/ambari.repo

Step 2: Install, Setup, and Start Ambari Server

yum install ambari-server 

[root@jifeng02 jifeng]# yum install ambari-server

版本 重要的事情说三遍，ambari是HDP傻瓜式安装管理的服务，所以都已经傻瓜式安装了，就要搞清楚自己装的版本匹不匹配 查看版本匹配链接：添加链接描述 环境 既然都要装ambari管理集群了，那么先把系统搞好嘛。linux系统优先使用centOS，毕竟这个系统目的是做主流服务器的环境 ，用其他的也行，深度或者乌班图都可以，但是依赖管理一般都不一样，自己要先搞个yum来管理，安装的时候也会出现各种各样的小问题，不嫌麻烦可以试试 这里要说明 ambari对centos的支持版本一个是centos6 一个是ce

### 安装 Ambari 的步骤 #### 准备工作 为了在 CentOS 7 上成功安装 Ambari，需先确保环境已准备好。这包括但不限于确认操作系统版本为 CentOS 7 并更新至最新状态。 #### 安装 Java 环境 由于 Hadoop 和 Ambari 均依赖于 Java 环境，因此首先需要安装适合的 JDK 版本[^1]。可以通过官方源或其他可信渠道获取并安装 OpenJDK 或 Oracle JDK。 #### 下载 Ambari 软件包 通过 `wget` 工具从 Hortonworks 提供的公共仓库下载最新的 Ambari 发行版以及对应的 `.repo` 文件： ```bash wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.7.4.0/ambari.repo -O /etc/yum.repos.d/ambari.repo wget https://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.7.4.0/ambari-2.7.4.0-centos7.tar.gz ``` 此操作会将必要的资源放置到系统的适当位置以便后续安装过程调用[^5]。 #### 安装 Ambari Server 及 Agent 完成上述准备工作之后，可以继续进行 Ambari server 和 agent 组件的具体部署。对于所有节点而言，均需执行如下命令来安装 ambari-agent: ```bash yum install ambari-agent ``` 而在 Master 节点，则还需额外配置并启动 Ambari server : ```bash yum install ambari-server ambari-server setup ambari-server start ``` 以上命令用于初始化服务器端设置并向集群中的其他机器分发所需的配置文件[^3]。 #### 同步配置文件 为了让整个集群能够正常运作，还需要把 `/etc/yum.repos.d/ambari.repo` 文件复制给每一个 Slave Node 。假设存在两个 slave nodes (node1 和 node2)，则可以在 master 上运行下面两条指令实现同步目的： ```bash scp /etc/yum.repos.d/ambari.repo node1:/etc/yum.repos.d/ scp /etc/yum.repos.d/ambari.repo node2:/etc/yum.repos.d/ ``` 这样做的目的是让所有的节点都能访问相同的软件库来进行组件安装和升级活动。 #### 开始使用 Ambari 当一切准备就绪后，打开浏览器输入 Master IP 地址加上默认端口号(通常是8080)即可进入 Web UI 页面开始管理 Hadoop 集群了。
