大數據平臺HDP搭建

1、概述

Apache Ambari是一個基於Web的支持Apache Hadoop集羣的供應、管理和監控的開源工具，Ambari已支持大多數Hadoop組件，包括HDFS、MapReduce、Hive、Pig、 Hbase、Zookeeper、Sqoop和Hcatalog等。提供Web UI進行可視化的集羣管理，簡化了大數據平臺的安裝、使用難度。

2、安裝部署

2.1 主機規劃

序號	IP地址	主機名	系統版本
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 基礎環境部署

a.修改主機名配置hosts

systemctl stop firewalld
hostnamectl set-hostname  ambari-server   #更改個主機名
sed -i 's/SELINUX=enforcing/SELINUX=disable/g' /etc/selinux/config
setenforce 0
cat >>/etc/hosts<<EOF    #添加各個節點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免密鑰登陸其餘節點

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

c.在ambari-server安裝數據庫
在ambari的setup中咱們能夠選擇使用默認的postgresql，也能夠自定義使用其餘數據庫，此處選用mariadb，便於後期管理維護

yum -y install mariadb-server mysql-connector-java
systemctl start mariadb
mysql -uroot password "mysqladmin"
登陸數據庫後咱們採用root登陸

d.配置本地yum源
因爲ambari的各個組件包很大,HDP大約快6G，咱們採起離線安裝方式，將ambari-server配置爲yum源，事先在網上下載HDP、HDP-UTILS和Ambari
軟件版本：

參考url：ambari各版本參考連接
HDP和HDP UTILS參考連接

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
