Apache Ambari是一种基于Web的工具，支持Apache Hadoop集群的供应、管理和监控。Ambari目前已支持大多数Hadoop组件，包括HDFS、MapReduce、Hive、Pig、 Hbase、Zookeper、Sqoop和Hcatalog等。下面与大家分享在CentOS 6.5下安装Ambari 的步骤。
一、前期环境准备
1.安装epel源
2.安装pdsh
yum -y install pdsh
3.在master和slave上配置hosts
cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.40.217 ambari
192.168.40.216 slave
4.设置免密码登录
ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase): #输入空格
Enter same passphrase again: #输入空格
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:
01:f9:c3:e6:e2:cc:46:1c:55:68:c4:2d:2b:eb:77:09 root@localhost.localdomain
The key's randomart image is:
+--[ RSA 2048]----+
| .+.+. |
| ..* . |
| =.o |
| o *. |
| . *S. |
| = E |
| * . . . |
| * . o |
| . . . |
+-----------------+
[root@ambari ~]# cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
[root@ambari ~]# scp ~/.ssh/authorized_keys master:/root/.ssh/
[root@ambari ~]# scp ~/.ssh/authorized_keys slave:/root/.ssh/
5.关闭selinux 和防火墙
二、安装ambari
1.配置yum源
[root@ambari ~]# wget
[root@ambari ~]# mv ambari.repo /etc/yum.repos.d/
2.安装ambari-server
[root@ambari ~]# yum -y install ambari-server #过程比较慢，ambari-server包有80M大小
3.本地配置
[root@ambari ~]# ambari-server setup
Using python /usr/bin/python2.6

###这里由于下载jdk速度过慢。我提前把jdk下载下来放到了/var/lib/ambari-server/resources/目录
[root@ambari ~]# cd /var/lib/ambari-server/resources/
[root@ambari resources]# mv /root/jdk-7u67-linux-x64.tar.gz .
4.启动服务
[root@ambari ~]# ambari-server start
Using python /usr/bin/python2.6
