大数据平台搭建（Ambari +HDP）
阅读原文时间：2021年06月23日阅读：1

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

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

gpgkey=http://yum.hdp/ambari/ambari/centos7/2.7.3.0-139/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins

  • 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
[HDP-3.1.0.0]

- 分发 ambari.repo 和 hdp.repo 配置文件

```bash
[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:$PWD
[root@yum yum]# scp hdp.repo node-01.hdp:$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

[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

mysql> CREATE USER ‘ambari‘@‘%‘IDENTIFIED BY ‘Ambari123‘;
Query OK, 0 rows affected (0.00 sec)

mysql>  GRANT ALL PRIVILEGES ON ambari.* TO ‘ambari‘@‘%‘;
Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

  • 创建hive数据库及hive库的用户名和密码

    [root@node-01 mysql]# mysql -uroot -p

mysql> CREATE USER ‘oozie‘@‘%‘IDENTIFIED BY ‘Oozie123‘;
Query OK, 0 rows affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON oozie.* TO ‘oozie‘@‘%‘;
Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

  • 创建ranger数据库及ranger库的用户名和密码（不用创建）

    [root@node-01 mysql]# mysql -uroot -p
Enter password: #输入数据库密码

mysql> create database ranger character set utf8;
Query OK, 1 row affected (0.00 sec)

mysql> CREATE USER ‘rangeradmin‘@‘%‘IDENTIFIED BY ‘Ranger123‘;
Query OK, 0 rows affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON ranger.* TO ‘rangeradmin‘@‘%‘;
Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES;

[root@node-03 ~]# yum -y install ambari-agent

访问Ambari web页面

默认端口8080，Username：admin；Password：admin；http://192.168.229.31:8080

开始安装集群

  • 启用安装向导创建集群

  • 配置集群名称

  • 选择版本

YUM 本地源如下：

HDP-3.1：http://yum.hdp/hdp/HDP/centos7

HDP-3.1-GPL:http://yum.hdp/hdp-gpl/HDP-GPL/centos7

HDP-UTILS-1.1.0.22:http://yum.hdp/hdp-utils/HDP-UTILS/centos7

  • 配置集群节点、密钥

  • 主机确认

  • 选择大数据组件

  • 节点分配

  • 分配从属与客户端

  • 定制服务

#重新执行命令
[root@node-01 ~]# ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar
Using python  /usr/bin/python
Setup ambari-server
Copying /usr/share/java/mysql-connector-java.jar to /var/lib/ambari-server/resources/mysql-connector-java.jar
If you are updating existing jdbc driver jar for mysql with mysql-connector-java.jar. Please remove the old driver jar, from all hosts. Restarting services that need the driver, will automatically copy the new jar to the hosts.
JDBC driver was successfully initialized.
Ambari Server ‘setup‘ completed successfully.

  • 集群整体部署

  • 开始安装（漫长的等待…）

  • 安装完毕

    不用担心警告，后期可以调整，搭建完成，可以在展示页面进行查看集群状态

  • 查看监控界面
