Apache Ambari是一種基於Web的工具，支持Apache Hadoop集羣的供應、管理和監控。Ambari目前已支持大多數Hadoop組件，包括HDFS、MapReduce、Hive、Pig、 Hbase、Zookeper、Sqoop和Hcatalog等。
一、前期環境準備
1.安裝epel源
2.安裝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.設置免密碼登錄
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): #回車 Enter same passphrase again: #回車 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 [email protected] The key's randomart p_w_picpath 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.關閉selinux 和防火牆
二、安裝ambari
1.配置yum源
[root@ambari ~]# wget http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.0.1/ambari.repo [root@ambari ~]# mv ambari.repo /etc/yum.repos.d/
2.安裝ambari-server
[root@ambari ~]# yum -y install ambari-server #過程比較慢，ambari-server包有80M大小
3.本地配置
[root@ambari ~]# ambari-server setup Using python /usr/bin/python2.6 Setup ambari-server Checking SELinux... SELinux status is 'disabled' Customize user account for ambari-server daemon [y/n] (n)? y Enter user account for ambari-server daemon (root): Adjusting ambari-server permissions and ownership...

Ambari Server 'setup' completed successfully. ###這裏由於下載jdk速度過慢。我提前把jdk下載下來放到了/var/lib/ambari-server/resources/目錄 [root@ambari ~]# cd /var/lib/ambari-server/resources/ [root@ambari resources]# mv /root/jdk-7u67-linux-x64.tar.gz .
4.啓動服務
[root@ambari ~]# ambari-server start Using python /usr/bin/python2.6 Starting ambari-server WARNING: The hostname was not found in the reverse DNS lookup. This may result in incorrect behavior. Please check the DNS setup and fix the issue. Ambari Server running with administrator privileges. Organizing resource files at /var/lib/ambari-server/resources... 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
啓動ambari報錯
WARNING: The hostname was not found in the reverse DNS lookup. This may result in incorrect behavior. Please check the DNS setup and fix the issue. ‘ 這個問題是由於沒有把主機名已經對應的ip加到/etc/hosts 導致的。
5.訪問web
http://ip:8080 默認用戶是admin，密碼admin
