hortonworks部署安装

环境准备

三台干净的服务器

192.168.83.131

192.168.83.132

192.168.83.133

服务器之间配置免秘钥登录

配置/etc/hosts 文件 保持一致

192.168.83.131 bigdata01.com Hmaster

192.168.83.132 bigdata02.com Hslave01

192.168.83.133 bigdata03.com Hslave02

环境搭建

执行yun命令清除，重新载入缓存

yumcleanall yum makecache

执行命令在官方地址下载ambir.repo文件指定 源

$ wget -nv http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.2.0.0/ambari.repo -O /etc/yum.repos.d/ambari.repo

执行后会产生/etc/yum.repos.d/ambari.repo文件

执行以下命令查看yum仓库

$ yum repolist

开始安装

下载ambari-server客户端

$ yum install  ambari-server

注意在这里可能会报错



两种方法可以解决：

1.运行

$ rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

可解决；

2.运行

$ yum.conf 文件,把里面的gpgcheck=1改为gpgcheck=0。

注：方法2的效果很好

3.最好的解决办法：

加上”–nogpgcheck”参数

$ yum install ambari-server –nogpgcheck*

运行ambari-server setup

以下是运行过程,安装时 还自动安装jdk可以根据需要选择,,推荐使用1.8版本(官方文档推荐)

2.

ambari 安装Hortonworks HDP 时在检测host时异常。

The following hosts have Transparent Huge Pages (THP) enabled。THP should be disabled to avoid potential Hadoop performance issues.

解决办法,在Linux下执行：
echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag
echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag
