大数据平台搭建（Ambari +HDP）

安装包

• ambari-2.7.3.0-centos7.tar.gz
• HDP-3.1.0.0-centos7-rpm.tar.gz
• HDP-UTILS-1.1.0.22-centos7.tar.gz
• HDP-GPL-3.1.0.0-centos7-gpl.tar.gz

Ambari

• 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。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 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管理工具。

• Ambari 自身也是一个分布式架构的软件，主要由两部分组成：Ambari Server 和 Ambari Agent。简单来说，用户通过 Ambari Server 通知 Ambari Agent 安装对应的软件；Agent 会定时地发送各个机器每个软件模块的状态给 Ambari Server，最终这些状态信息会呈现在 Ambari 的 GUI，方便用户了解到集群的各种状态，并进行相应的维护。

HDP

• HDP 是 hortonworks 的软件栈，里面包含了 Hadoop 生态系统的所有软件项目，比如 HBase、Zookeeper、Hive、Pig 等

HDP-UTILS

• HDP-UTILS 是工具类库

准备工作

集群节点规划

主机名	IP	功能	内存	磁盘
yum.hdp	192.168.229.30	Ambari/HDP packages	1G	50G
node-01.hdp	192.168.229.31	Ambari Server/Agent	3G	50G
node-02.hdp	192.168.229.32	Ambari Agent	2G	50G
node-03.hdp	192.168.229.33	Ambari Agent	2G	50G

克隆 4 台虚拟机

修改主机名

# vi /etc/hostname

修改 IP 地址

# vi /etc/sysconfig/network-scripts/ifcfg-ens33
# service network restart
# ping www.baidu.com

hosts 文件添加主机名和IP地址映射

• windows 系统

hosts 文件路径：C:WindowsSystem32driversetc

192.168.229.30 yum.hdp
192.168.229.31 node-01.hdp
192.168.229.32 node-02.hdp
192.168.229.33 ndoe-03.hpd

• centos 系统

[root@node-01 ~]# vi /etc/hosts
192.168.229.30 yum.hdp
192.168.229.31 node-01.hdp
192.168.229.32 node-02.hdp
192.168.229.33 node-03.hdp

配置免密

[root@yum ~]# ssh-keygen -t rsa
[root@yum ~]# ssh-copy-id yum.hdp
[root@yum ~]# ssh-copy-id node-01.hdp
[root@yum ~]# ssh-copy-id node-02.hdp
[root@yum ~]# ssh-copy-id node-03.hdp

[root@node-01 ~]# ssh-keygen -t rsa
[root@node-01 ~]# ssh-copy-id node-01.hdp
[root@node-01 ~]# ssh-copy-id node-02.hdp
[root@node-01 ~]# ssh-copy-id node-03.hdp

[root@node-02 ~]# ssh-keygen -t rsa
[root@node-02 ~]# ssh-copy-id node-02.hdp
[root@node-02 ~]# ssh-copy-id node-03.hdp

安装 mysql

在 node-01.hdp 主机节点上安装 mysql，安装教程

在 yum.hdp 上安装 Ambari

安装 yum 相关工具

[root@yum ~]# yum install yum-utils -y
[root@yum ~]# yum repolist
[root@yum ~]# yum install createrepo -y

上传安装包到 yum.hdp

创建 hdp 目录，将安装包上传到该目录下

[root@yum ~]# mkdir hdp

安装 Apache httpd

httpd 为 Apache HTTP 服务器程序，直接执行程序可启动服务器的服务

[root@yum ~]# yum install httpd -y

• 安装完成后，会生成 /var/www/html 目录（相当于 Tomcat 的 webapps 目录），进入到 /var/www/html 目录下，创建 ambari 和 hdp 目录，用来存放安装文件

  [root@yum ~]# cd /var/www/html/
  [root@yum html]# mkdir ambari hdp hdp-utils hdp-gpl
  
  [root@yum ~]# cd /root/hdp/
  [root@yum hdp]# tar -zxvf ambari-2.7.3.0-centos7.tar.gz -C /var/www/html/ambari/
  [root@yum hdp]# tar -zxvf HDP-UTILS-1.1.0.22-centos7.tar.gz -C /var/www/html/hdp-utils
  [root@yum hdp]# tar -zxvf HDP-3.1.0.0-centos7-rpm.tar.gz -C /var/www/html/hdp/
  [root@yum hdp]# tar -zxvf HDP-GPL-3.1.0.0-centos7-gpl.tar.gz -C /var/www/html/hdp-gpl/
  

• 启动 httpd 服务

  # 启动 httpd 服务
  [root@yum ~]# systemctl start httpd
   Active: active (running) since 三 2021-05-26 15:24:34 CST; 16s ago #表示服务正在运行
       Docs: man:httpd(8)
             man:apachectl(8)
   Main PID: 1247 (httpd)
  # 查看 httpd 服务状态
  [root@yum ~]# systemctl status httpd
  # 设置 httpd 服务开机启动
  [root@yum ~]# systemctl enable httpd
  

• 默认端口80，浏览器输入：http://192.168.229.30

配置本地 Repo 数据源

• 创建 ambari.repo 配置文件

  [root@yum yum]# cd /etc/yum.repos.d
  [root@yum yum.repos.d]# vim ambari.repo
  
  #VERSION_NUMBER=2.7.3.0-139
  [ambari-2.7.3.0]
  #json.url = http://public-repo-1.hortonworks.com/HDP/hdp_urlinfo.json

• 创建 hdp.repo 配置文件

  [root@yum yum]# cd /etc/yum.repos.d
  [root@yum yum.repos.d]# vim hdp.repo
  
  #VERSION_NUMBER=3.1.0.0-78

• 分发 ambari.repo 和 hdp.repo 配置文件

  [root@yum yum]# cd /etc/yum.repos.d
  [root@yum yum]# scp ambari.repo node-01.hdp:$PWD
  [root@yum yum]# scp ambari.repo node-02.hdp:$PWD
  [root@yum yum]# scp ambari.repo node-03.hdp:$PWD

  [root@yum yum]# scp hdp.repo node-02.hdp:$PWD
  [root@yum yum]# scp hdp.repo node-03.hdp:$PWD
  

• 生成本地源

  使用 createrepo 命令，创建 yum 本地源（软件仓库），即为存放本地特定位置的众多rpm包建立索引，描述各包所需依赖信息，并形成元数据

  [root@yum yum]# createrepo /var/www/html/hdp/HDP/centos7/
  Spawning worker 0 with 101 pkgs
  Spawning worker 1 with 100 pkgs
  Workers Finished
  Saving Primary metadata
  Saving file lists metadata
  Saving other metadata
  Generating sqlite DBs
  Sqlite DBs complete
  
  [root@yum yum]# createrepo /var/www/html/hdp-utils/HDP-UTILS/centos7/
  Spawning worker 0 with 8 pkgs
  Spawning worker 1 with 8 pkgs
  Workers Finished
  Saving Primary metadata
  Saving file lists metadata
  Saving other metadata
  Generating sqlite DBs
  Sqlite DBs complete
  
  [root@yum yum.repos.d]# createrepo /var/www/html/hdp-gpl/HDP-GPL/centos7/
  Spawning worker 0 with 2 pkgs
  Spawning worker 1 with 2 pkgs
  Workers Finished
