一、集群软硬件环境准备：
操作系统： centos 7 x86_64.1804
Ambari版本：2.7.0
HDP版本：3.0.0
HAWQ版本：2.3.0
5台PC作为工作站：
| ep-bd01 | ep-bd02 | ep-bd03 | ep-bd04 | ep-bd05 |
其中ep-bd01作为主节点，用于安装ambari-server。
二、配置操作系统，安装必备软件
1，CentOS7操作系统环境配置，安装必备软件。
2，安装配置NTP服务，保证集群时间保持同步，以防止由于时间不同而造成掉线故障。
详细看随笔：基于【CentOS-7+ Ambari 2.7.0 + HDP 3.0】搭建HAWQ数据仓库之——安装配置NTP服务，保证集群时间保持同步
见《安装配置NTP服务》
3，安装MariaDB Server用于Ambari server以及Hue和Hive
详细过程，参见：基于【CentOS-7+ Ambari 2.7.0 + HDP 3.0】搭建HAWQ数据仓库之一 —— MariaDB 安装配置
三、搭建本地仓库：
1，下载软件包：
cd /root mkdir downloads cd downloads wget http://public-repo-1.hortonworks.com/HDP-GPL/centos7/3.x/updates/3.0.0.0/HDP-GPL-3.0.0.0-centos7-gpl.tar.gz wget http://public-repo-1.hortonworks.com/HDP/centos7/3.x/updates/3.0.0.0/hdp.repo wget http://public-repo-1.hortonworks.com/HDP/centos7/3.x/updates/3.0.0.0/HDP-3.0.0.0-1634.xml wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.7.0.0/ambari.repo wget http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.22/repos/centos7/HDP-UTILS-1.1.0.22-centos7.tar.gz wget http://public-repo-1.hortonworks.com/HDP/centos7/3.x/updates/3.0.0.0/HDP-3.0.0.0-centos7-rpm.tar.gz wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.7.0.0/ambari-2.7.0.0-centos7.tar.gz
2、搭建本地仓库：
安装并开启Apache HTTP服务
yum install httpd -y systemctl enable httpd systemctl start httpd
确保/var/www/html目录存在，没有的话创建。
mkdir -p /var/www/html
创建HDP，HDF子目录
cd /var/www/html mkdir hdp hdf
解开下载的软件包：
cd /var/www/html tar -zxvf /root/downloads/ambari-2.7.0.0-centos7.tar.gz -C . tar -zxvf /root/downloads/HDP-3.0.0.0-centos7-rpm.tar.gz -C ./hdp tar -zxvf /root/downloads/HDP-GPL-3.0.0.0-centos7-gpl.tar.gz -C ./hdp tar -zxvf /root/downloads/HDP-UTILS-1.1.0.22-centos7.tar.gz -C ./hdp
修改下载的ambari.repo，
vim ambari.repo
安装如下内容修改，[注意版本号，需要根据具体下载的版本不同修改，解压后自己查看一下]：
#VERSION_NUMBER=2.7.0.0-897
[ambari-2.7.0.0]
#json.url = http://public-repo-1.hortonworks.com/HDP/hdp_urlinfo.json
name=ambari Version - ambari-2.7.0.0
baseurl=http://ep-bd01/ambari/centos7/2.7.0.0-897
gpgcheck=1
gpgkey=http://ep-bd01/ambari/centos7/2.7.0.0-897/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1
移动到/etc/yum.repos.d
mv ambari.repo /etc/yum.repos.d/ambari-local.repo
修改下载的hdp.repo，
vim hdp.repo
安装如下内容修改，[注意版本号，需要根据具体下载的版本不同修改，解压后自己查看一下]：
#VERSION_NUMBER=3.0.0.0-1634 [HDP-3.0.0.0] name=HDP Version - HDP-3.0.0.0 baseurl=http://ep-bd01/hdp/HDP/centos7/3.0.0.0-1634 gpgcheck=1 gpgkey=http://ep-bd01/hdp/HDP/centos7/3.0.0.0-1634/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins enabled=1 priority=1 [HDP-UTILS-1.1.0.22] name=HDP-UTILS Version - HDP-UTILS-1.1.0.22 baseurl=http://ep-bd01/hdp/HDP-UTILS/centos7 gpgcheck=1 gpgkey=http://ep-bd01/hdp/HDP-UTILS/centos7/1.1.0.22/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins enabled=1 priority=1
保存退出，移动到/etc/yum.repos.d/
mv hdp.repo /etc/yum.repos.d/hdp-local.repo
四、主节点安装ambari server
1，使用刚才配置好的本地仓库，直接yum命令安装。
yum install ambari-server -y
2，查看ambari server 状态
systemctl status ambari-server ● ambari-server.service - LSB: ambari-server daemon Loaded: loaded (/etc/rc.d/init.d/ambari-server; bad; vendor preset: disabled) Active: inactive (dead) Docs: man:systemd-sysv-generator(8)
看到ambari server已成功安装了。
3，配置mariadb，建立用户和数据库供ambari使用
建立数据库用户ambari
mysql -uroot -p
MariaDB [(none)]> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
MariaDB [mysql]> grant all privileges on *.* to ‘ambari‘@‘%‘ identified by ‘ambari‘;
Query OK,0 rows affected (0.06 sec)
MariaDB [mysql]> flush privileges;
Query OK,0 rows affected (0.00 sec)
MariaDB [mysql]>
建立数据库ambari，并运行ambari数据库建表sql命令文件。
MariaDB [mysql]> create database ambari; Query OK,1 row affected (0.01 sec) MariaDB [mysql]> use ambari; Database changed MariaDB [ambari]> source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql; Query OK,0 rows affected (0.01 sec) Query OK,0 rows affected (0.00 sec) Query OK,0 rows affected (0.06 sec) Query OK,0 rows affected (0.00 sec) Statement prepared ... ...
4，配置ambari server
执行命令
ambari-server setup
回答选择项，其中JDK选择“”Custom“”，给出系统安装目录，数据库一定要选择高级配置，指定mariadb数据库和用户，本人系统中详细过程如下：
