5.安装ambari
[root@hadoop1 ~]# yum install wget安装wget工具 首先需要获取 Ambari 的公共库文件（public repository）。登录到 Linux 主机并执行下面的命令（也可以自己手工下载）：wget http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.0.1/ambari.repo将下载的 ambari.repo 文件拷贝到 Linux 的系统目录/etc/yum.repos.d/。拷贝完后，我们需要获取该公共库的所有的源文件列表。依次执行以下命令。yum clean allyum list|grep ambari Cleaning up list of fastest mirrors[root@hadoop1 yum.repos.d]# yum list|grep ambariambari-agent.x86_64 2.0.1-45 Updates-ambari-2.0.1ambari-log4j.noarch 2.0.1.45-1 Updates-ambari-2.0.1ambari-metrics-collector.x86_64 2.0.1-45 Updates-ambari-2.0.1ambari-metrics-common.noarch 2.0.1-45 Updates-ambari-2.0.1ambari-metrics-hadoop-sink.x86_64 2.0.1-45 Updates-ambari-2.0.1ambari-metrics-monitor.x86_64 2.0.1-45 Updates-ambari-2.0.1ambari-server.noarch 2.0.1-45 Updates-ambari-2.0.1hdp_mon_ganglia_addons.noarch 2.0.1.45-1.el6 Updates-ambari-2.0.1hdp_mon_nagios_addons.noarch 2.0.1.45-1.el6 Updates-ambari-2.0.1
6.ambari配置
待安装完成后，便需要对 Ambari Server 做一个简单的配置。执行下面的命令。
amari-server setup
[root@hadoop1 ~]# ambari-server setupUsing python /usr/bin/python2.6Setup ambari-serverChecking SELinux...SELinux status is 'enabled'SELinux mode is 'enforcing'Temporarily disabling SELinuxWARNING: SELinux is set to 'permissive' mode and temporarily disabled.OK to continue [y/n] (y)? yCustomize user account for ambari-server daemon [y/n] (n)? Adjusting ambari-server permissions and ownership...Checking iptables...WARNING: iptables is running. Confirm the necessary Ambari ports are accessible. Refer to the Ambari documentation for more details on ports.OK to continue [y/n] (y)? Checking JDK...[1] Oracle JDK 1.7[2] Oracle JDK 1.6[3] - Custom JDK==============================================================================Enter choice (1): 1To download the Oracle JDK and the Java Cryptography Extension (JCE) Policy Files you must accept the license terms found at http://www.oracle.com/technetwork/java/javase/terms/license/index.html and not accepting will cancel the Ambari Server setup and you must install the JDK and JCE files manually.Do you accept the Oracle Binary Code License Agreement [y/n] (y)? Downloading JDK from http://public-repo-1.hortonworks.com/ARTIFACTS/jdk-7u67-linux-x64.tar.gz to /var/lib/ambari-server/resources/jdk-7u67-linux-x64.tar.gz
7.ambari启动
简单的 setup 配置完成后。就可以启动 Ambari 了。运行下面的命令。
ambari-server start
