1、虚拟机建立两台电脑，分别为hdp01和hdp02.
2、服务器基本设置

vim /etc/hosts
192.168.1.210   hdp01
192.168.1.220   hdp02
vim /etc/selinux/config
SELINUX=disabled
vim /etc/sysconfig/network
HOSTNAME=hdp01     #主机名分别为hdp01, hdp02

3、关闭不必要的服务（可选）

chkconfig NetworkManager off
chkconfig abrt-ccpp off
chkconfig abrtd off
chkconfig acpid off
chkconfig atd off 
chkconfig bluetooth off
chkconfig cpuspeed off
chkconfig cpuspeed off
chkconfig ip6tables off
chkconfig iptables off
chkconfig netconsole off
chkconfig netfs off
chkconfig postfix off
chkconfig restorecond off
chkconfig httpd off

4、在hdp01上安装ambari
(1).下载HDP repo
下载HDP提供的yum repo文件并拷贝到/etc/yum.repos.d中

[root@hdp01 ~]# wget http://public-repo-1.hortonworks.com/ambari/centos6/1.x/updates/1.4.1.61/ambari.repo
--2014-03-10 04:57:58--  http://public-repo-1.hortonworks.com/ambari/centos6/1.x/updates/1.4.1.61/ambari.repoResolving public-repo-1.hortonworks.com... 54.230.127.224, 205.251.212.150, 54.230.124.207, ...

[root@hdp01 ~]# cp ambari.repo /etc/yum.repos.d/

（2）.使用yum安装ambari-server

[root@hdp01 ~]# yum –y install ambari-server
...

  ambari-server.noarch 0:1.4.1.61-1

Complete!

5、配置root用户的ssh互信
分别在hdp01和hdp02生成key,再通过ssh-copy-id拷贝到hdp01和hdp02上去

[root@hdp01 ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory ' /root/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /hroot/.ssh/id_rsa.
...
[root@hdp02 .ssh]# ssh-copy-id hdp01
The authenticity of host 'hdp01 (192.168.1.210)' can't be established.
RSA key fingerprint is 90:3b:db:2d:c4:34:49:03:e6:d7:cc:cb:b7:60:4d:d0.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'hdp01,192.168.1.210' (RSA) to the list of known hosts.
root@hdp01's password: 
Now try logging into the machine, with "ssh 'hdp01'", and check in:
  .ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.

[root@hdp02 .ssh]# ssh-copy-id hdp02
The authenticity of host 'hdp02 (192.168.1.220)' can't be established.
RSA key fingerprint is 11:cb:c9:9e:b6:c0:a1:95:98:fa:42:aa:95:5f:cf:98.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'hdp02,192.168.1.220' (RSA) to the list of known hosts.

  .ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.

6、配置ambari server
Apache Ambari是基于Web的Apache Hadoop的自动部署、管理和监控工具。这里ambari server的metastore使用了自带了postgre数据库。

[root@hdp01 ~]# ambari-server setup
Using python  /usr/bin/python2.6

使用root用户来启动ambari server

[root@hdp01 ~]$ ambari-server start
Using python  /usr/bin/python2.6
Starting ambari-server
Unable to check iptables status when starting without root privileges.
Please do not forget to disable or adjust iptables if needed
Unable to check PostgreSQL server status when starting without root privileges.
Please do not forget to start PostgreSQL server.
Server PID at: /var/run/ambari-server/ambari-server.pid
Server out at: /var/log/ambari-server/ambari-server.out
Server log at: /var/log/ambari-server/ambari-server.log
Ambari Server 'start' completed successfully.

7、使用浏览器打开http://hdp01:8080/, 输入admin/admin
ssh private key那里加入hdp01的id_rsa

8、ambari-agent 安装完成，可以通过ambari-agent命令来控制

[root@hdp02 Desktop]# ambari-agent status
ambari-agent currently not running
Usage: /usr/sbin/ambari-agent {start|stop|restart|status}
#在hdp01和hdp02上让ambari-agent在开机时启动
[root@hdp02 Desktop]# chkconfig ambari-agent –level 35 on

9、安装你需要的各种服务
