HDP 大数据平台搭建

一、概述

Apache Ambari是一个基于Web的支持Apache Hadoop集群的供应、管理和监控的开源工具，Ambari已支持大多数Hadoop组件，包括HDFS、MapReduce、Hive、Pig、 Hbase、Zookeeper、Sqoop和Hcatalog等。提供Web UI进行可视化的集群管理，简化了大数据平台的安装、使用难度。

二、安装部署

2.1 主机规划

| 序号 | IP地址 | 主机名 |系统版本|
| -------- | -------- | -------- |
| 1 | 172.20.2.222 | ambari-server |centos7.3
| 2 | 172.20.2.203 | hadoop-1 |centos7.3
| 3 | 172.20.2.204 | hadoop-2 |centos7.3
| 4 | 172.20.2.205 | hadoop-3 |centos7.3

2.2 部署

2.2.1 基础环境部署

a.修改主机名配置hosts

systemctl stop firewalld
hostnamectl set-hostname  ambari-server   #更改个主机名
sed -i 's/SELINUX=enforcing/SELINUX=disable/g' /etc/selinux/config
setenforce 0
cat >>/etc/hosts<<EOF    #添加各个节点hosts解析 172.20.2.222 ambari-server 172.20.2.203 hadoop-1 172.20.2.204 hadoop-2 172.20.2.205 hadoop-3 EOF 

b.配置ambari-server免密钥登录其他节点

ssh-keygen -t rsa     #在ambari-server生成密钥对
for num in `seq 1 3`;do ssh-copy-id -i /root/.ssh/id_rsa.pub root@hadoop-$num;done 

c.在ambari-server安装数据库
在ambari的setup中我们可以选择使用默认的postgresql，也可以自定义使用其他数据库，此处选用mariadb，便于后期管理维护

yum -y install mariadb-server mysql-connector-java
systemctl start mariadb
mysql -uroot password "mysqladmin"
登录数据库后我们采用root登录

d.配置本地yum源
由于ambari的各个组件包很大,HDP大约快6G，我们采取离线安装方式，将ambari-server配置为yum源，事先在网上下载HDP、HDP-UTILS和Ambari
软件版本：

参考url：ambari各版本参考链接
HDP和HDP UTILS参考链接

ambari	HDP	HDP-UTILS
2.4.1.0	2.5.0.0	1.1.0.21

yum install httpd -y && systemctl start httpd
mkdir /software && cd /software

2.2.2 安装配置ambari

a.安装ambari server

yum clean all
yum makecache
yum -y install ambari-server
#进入数据库创建ambari库和导入数据
mysql>create database ambari DEFAULT CHARSET utf8;
mysql>use ambari
