# 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
    JAVA: 1.8.0_131
    Ambari: 2.7.1

## 平台搭建 ##

### 安装需要的依赖 ###

# 安装配置时间同步服务
    $ yum install chrony
    
    # 设置开机启动
    $ systemctl enable chronyd.service
    
    # 启动时间同步服务
    $ systemctl start chronyd.service
    
    # 安装时间同步服务
    $ yum install ntp
    
    # 开启ntpd服务
    $ systemctl start ntpd
    
    # 设置为开机启动
    $ systemctl enable ntpd
    
    # 查看是否为开机启动
    $ systemctl is-enabled ntpd
    
    # 关闭防火墙
    $ systemctl disable firewalld
    
    # 查看SElinux
    $ sestatus
    
    # 修改 SELINUX=enforcing 改为 SELINUX=disabled
    $ vi /etc/sysconfig/selinux
    
    # 下载Ambari yum 源文件
    $ wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.7.1.0/ambari.repo -O /etc/yum.repos.d/ambari.repo

### 搭建本地HDP yum源（后续探索暂未验证） ###

# 安装httpd服务
    $ yum install httpd
    
    # 设置为开机启动
    $ systemctl enable httpd
    
    # 创建hdp文件存放目录
    $ mkdir -p /var/www/html/hdp
    
    # 下载 HDP 3.0.1
    $ wget http://public-repo-1.hortonworks.com/HDP/centos7/3.x/updates/3.0.1.0/HDP-3.0.1.0-centos7-rpm.tar.gz
    
    # 下载 HDP-UTILS 1.1.0.22
    $ wget http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.21/repos/centos7/HDP-UTILS-1.1.0.22-centos7.tar.gz
    
    # 新增hdp.repo
