Apache Ambari是一种基于Web的工具，支持Apache Hadoop集群的创建、管理和监控。Ambari已支持大多数Hadoop组件，包括HDFS、MapReduce、Hive、Pig、 Hbase、Zookeeper、Sqoop和Hcatalog等；除此之外，Ambari还支持Spark、Storm等计算框架及资源调度平台YARN。
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。

一、搭建内部yum源

网络原因，直接安装速度将会特别慢甚至失败，下载镜像搭建一个内部yum源

1、下载文件（可评论找我发）

Ambari、HDP 、HDP-GPL 和 HDP-UTILS

2、解压并转存到指定路径，使用httpd或者nginx方式访问

http 将解压文件放在： /var/www/html
nginx 开启浏览目录：autoindex_localtime on;

配置内网能访问到的地址

3、新增 /etc/yum.repos.d/ambari.repo

二、安装ambari-server

yum install -y ambari-server && yum clean all
wget http://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.49.tar.gz
wget https://jdbc.postgresql.org/download/postgresql-42.3.1.jar

导入mysql

mysql -h127.0.0.1 -P3306 -uroot -p'123456' <<EOF
CREATE DATABASE ambari;
use ambari;
CREATE USER 'ambari'@'%' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';
CREATE USER 'ambari'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'localhost';
FLUSH PRIVILEGES;
source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql
show tables;
EOF

修改配置

vim /etc/systemd/system/ambari-server.service

[Install]
WantedBy=multi-user.target

[Unit]
Description=Ambari Server Service
After=network-online.target network.service

[Service]
Type=forking
Restart=on-failure
TimeoutSec=5min
IgnoreSIGPIPE=no
KillMode=process
GuessMainPID=no
RemainAfterExit=yes
Environment='AMBARI_JVM_ARGS=-XX:MaxPermSize=512m'
ExecStart=/usr/sbin/ambari-server start
ExecStop=/usr/sbin/ambari-server stop

最后启动

ambari-server start
systemctl enable ambari-server

启动没有报错则可访问8080端口打开web后台

三、安装ambari-agent

yum install -y ambari-agent && yum clean all

vim /etc/systemd/system/ambari-agent.service

[Install]
WantedBy=multi-user.target

[Unit]
Description=Ambari Agent Service
After=network-online.target network.service

[Service]
Type=forking
Restart=no
TimeoutSec=5min
IgnoreSIGPIPE=no
KillMode=process
GuessMainPID=no
RemainAfterExit=yes
ExecStart=/etc/rc.d/init.d/ambari-agent start
ExecStop=/etc/rc.d/init.d/ambari-agent stop

最后启动agent

ambari-agent start
systemctl enable ambari-agent
