ambari实战 (2)ambari安装        http://zilongzilong.iteye.com/blog/2272223

 

1.Ambari 的安装准备

    1.1 用VMWARE搭建三台linux虚拟机,三台机器配置免秘钥登录

        1.1.1 三台虚拟机配置如下:

hostname ip OS
hadoop1 192.168.202.132 Linux version 2.6.32-358.el6.x86_64,CentOS release 6.4 (Final)
hadoop2 192.168.202.136 Linux version 2.6.32-358.el6.x86_64,CentOS release 6.4 (Final)
hadoop3 192.168.202.173 Linux version 2.6.32-358.el6.x86_64,CentOS release 6.4 (Final)

        1.1.2配置hostname,设置主机名

         vi /etc/sysconfig/network

 

NETWORKING=yes
HOSTNAME=hadoop1

        1.1.3配置host,设置ip和主机名的映射

         vi /etc/hosts

 

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.202.132 hadoop1
192.168.202.136 hadoop2
192.168.202.173 hadoop3

        1.1.4配置SSH免密码登录

 

 

[root@hadoop1 yum.repos.d]# 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 /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
62:a2:d3:40:36:c2:1d:a3:c6:d2:75:5c:4f:98:bc:2b root@hadoop1
The key's randomart image is:
+--[ RSA 2048]----+
|   o...o.o.      |
|o.o.o.. +o       |
|o==.     ..      |

[root@hadoop1 .ssh]# chmod 600 /root/.ssh/authorized_keys

    1.2确保 Yum 可以使用

 

     通过公共库(public repository),安装 Hadoop 这些软件,背后其实就是应用 Yum 在安装公共库里面的 rpm 包。所以这里需要您的机器都能访问 Internet。

    1.3Python安装,版本最好大于或等于2.6

 

#查看Python版本
[root@hadoop3 ~]# python -V
Python 2.6.6

 

    1.4安装ambari时候尽量用root安装

 

Ambari 的 Server 会 SSH 到 Agent 的机器,拷贝并执行一些命令。因此我们需要配置 Ambari Server 到 Agent 的 SSH 无密码登录。
Ambari 会创建一些 OS 用户。

 

 

2.Ambari安装

    2.1下载Ambari 的公共库文件(public repository)

 

wget http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.0.1/ambari.repo

     2.2将下载的 ambari.repo 文件拷贝到 Linux 的系统目录/etc/yum.repos.d/

 

 

mv ambari.repo /etc/yum.repos.d/ambari.repo

     2.3获取该公共库的所有的源文件列表

 

 

[root@hadoop1 hadoop]# cd /etc/yum.repos.d/
[root@hadoop1 yum.repos.d]# yum clean all
[root@hadoop1 ~]# yum list|grep ambari
ambari-server.noarch               2.0.1-45        @Updates-ambari-2.0.1
