Ambari安装文档

一、系统版本和环境要求

系统：CentOS 7

Ambari: ambari-2.6.1.5

内存：主节点 至少4G内存以上

二、 准备工作

1、准备机器172.172.160.101-107

2、各个机器进行hostname配置

         Vi   /etc/hostname

关闭SELinux  setenforce 0

 

• 临时关闭SELinux 

setenforce 0

• 临时打开SELinux 

setenforce 1

• 查看SELinux状态 

getenforce

• 开机关闭SELinux 

编辑/etc/selinux/config文件，如下图，将SELINUX的值设置为disabled。下次开机SELinux就不会启动了。

3、进行管理服务主机与其他机器免密访问

         在101机器上执行

         Ssh-keygen

         ssh-copy-id   其他机器地址(例如 ssh-copy-id 172.172.160.102)

4、进行各个服务器的防火墙关闭

systemctl stop firewalld.service

 

systemctl disable firewalld.service

 

systemctl status firewalld.service

5、时间同步

         安装ntp:

yum install ntp

具体操作请参见教程：

https://www.linuxidc.com/Linux/2015-11/124911.htm

6、各个机器安装java

7、在其中一台机器上配置hosts，例如101

    Vi /etc/hosts

    添加内容：

  172.172.160.101 bigdata101.com

172.172.160.102 bigdata102.com

172.172.160.103 bigdata103.com

172.172.160.104 bigdata104.com

172.172.160.105 bigdata105.com

172.172.160.106 bigdata106.com

172.172.160.107 bigdata107.com

    分发给各个机器：

    Scp –r /etc/hosts 172.172.160.102:/etc/hosts

三、 开始安装ambari及搭建集群

1、首先将做好的离线源ambari.repo放在101机器的/etc/yum.repos.d/目录下

2、安装并启动httpd服务

         yum install httpd –y

service httpd restart

3、安装ambari-server

    yum -y install ambari-server

ambari-server setup

    这时根据一下提示进行操作：
