Apache Ambari安装过程（CentOS 6.5）

一.准备环境

1.host

　　本人准备了三台服务器,

vim /etc/hosts　　

192.168.1.131 dk11
192.168.1.132 dk21
192.168.1.133 dk31

2.免密 SSH

cd ~  
ssh-keygen  

一直按回车

配置本地的免登录

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys  

配置其他节点

scp ~/.ssh/authorized_keys dk11:/root/.ssh/  
scp ~/.ssh/authorized_keys dk21:/root/.ssh/  
scp ~/.ssh/authorized_keys dk31:/root/.ssh/  

　OK .测试一下是否成功: ssh dk21, ssh dk31

出现

Last login: Tue Mar 14 05:35:35 2017 from dk11

说明成功

3. 关闭防火墙

4.同步集群的时间（ntp） 

5. 关闭 selinux ,需要重启

vim /etc/selinux/config 

SELINUX=disabled

重启.

二、安装Ambari Server

2.1添加 yum 源

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

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

yum install epel-release 

检查是否成功 :yum repolist

[root@dk11 run]# yum repolist

出现 epel 则成功

2.2 安装 

yum install ambari-server  

2.3 设置

ambari-server setup

会提示安装jdk，网速好的可以确定，否则可以下载jdk-6u31-linux-x64.bin，放到/var/lib/ambari-server/resources/下面
接着会提示配置用的数据库，可以选择Oracle或postgresql，选择n会按默认配置
数据库类型：postgresql
数据库：ambari
用户名：ambari
密码：bigdata
如果提示Oracle JDK license，yes
等待安装完成

三、配置Ambari 

启动 Ambari-server

ambari-server start  

登录: http://192.168.1.133:8080  

用户名密码: admin,admin

开始配置

点击

 

注意,秘钥 在 /root/.ssh/id_rsa 中 

四.遇到的错误

4.1  Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

4.2 ambari 版本太低

Cluster primary OS type is redhat6 and local OS type is centos5 Local OS is not compatible with cluster primary OS. Please perform manual bootstrap on this host.

 检查是不是你下载的

wget http://public-repo-1.hortonworks.com/ambari/centos6/1.x/updates/1.2.4.9/ambari.repo

如果是,请改成 本文推荐的版本

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

4.3 . error:100AE081:elliptic curve routines:EC_GROUP_new_by_curve_name:unknown group

解决方案: yum install openssl
