安装 Ambari 2.6.0 + HDP 2.6.3 搭建Hadoop集群（CentOS7）简明版

三台虚拟机

72.16.243.146 db_server_01

72.16.243.147 db_server_02

72.16.243.148 db_server_03

设置主机名

第1台：

hostnamectl set-hostname db_server_01

第2台：

hostnamectl set-hostname db_server_02

第3台：

hostnamectl set-hostname db_server_03

设置hosts，所有节点都设置

vi /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

172.16.243.146 db_server_01 db_server_01.hadoop

172.16.243.147 db_server_02 db_server_02.hadoop

172.16.243.148 db_server_03 db_server_03.hadoop

每台节点里配置全限定域名(FQDN)

第1台：

vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=db_server_01.hadoop

第2台：

vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=db_server_02.hadoop

第3台：

vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=db_server_03.hadoop

配置SSH免密码登录

1、在主节点（第1台）执行

ssh-keygen

cd ~/.ssh/

cat id_rsa.pub >>authorized_keys

chmod 600 ~/.ssh

chmod 600 ~/.ssh/authorized_keys

2、在所有从节点（第2、3台）执行

mkdir ~/.ssh/

3、在主节点执行

scp /root/.ssh/authorized_keys root@172.16.243.147:/root/.ssh/authorized_keys

scp /root/.ssh/authorized_keys root@172.16.243.148:/root/.ssh/authorized_keys

开启NTP服务，所有节点都需要执行

yum install ntp

systemctl is-enabled ntpd

systemctl enable ntpd

关闭防火墙，所有机器都执行

systemctl disable firewalld

systemctl stop firewalld

关闭SELinux，所有机器都执行

#临时关闭

setenforce 0

#永久关闭

vi /etc/sysconfig/selinux

SELINUX=disabled

安装HTTP 服务器（第1台），允许 http 服务通过防火墙(永久)

yum install httpd

firewall-cmd --add-service=http

firewall-cmd --permanent --add-service=http

添加 Apache 服务到系统层使其随系统自动启动

systemctl start httpd.service

systemctl enable httpd.service

安装本地源制作相关工具

yum install yum-utils createrepo

创建目录

cd /var/www/html/

mkdir ambari

mkdir HDP-UTILS

cd /var/www/html/ambari/

下载Ambari 2.6.0

wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.6.0.0/ambari-2.6.0.0-centos7.tar.gz

下载HDP 2.6.3

wget http://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.6.3.0/HDP-2.6.3.0-centos7-rpm.tar.gz

下载HDP-UTILS 1.1.0.21

wget http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.21/repos/centos7/HDP-UTILS-1.1.0.21-centos7.tar.gz

解压文件

tar -zxvf ambari-2.6.0.0-centos7.tar.gz -C /var/www/html/ambari/

tar -zxvf HDP-2.6.3.0-centos7-rpm.tar.gz -C /var/www/html/ambari/

tar -zxvf HDP-UTILS-1.1.0.21-centos7.tar.gz -C /var/www/html/ambari/HDP-UTILS/

测验证httpd网站是否可用

http://172.16.243.146/ambari/

安装Mysql数据库

yum install mariadb-server

systemctl start mariadb

systemctl enable mariadb

数据库初始化设置

mysql_secure_installation

Enter current password for root (enter for none):<–初次运行直接回车

Set root password? [Y/n] <– 是否设置root用户密码，输入y并回车或直接回车

New password: <– 设置root用户的密码

Re-enter new password: <– 再输入一次你设置的密码

Remove anonymous users? [Y/n] <– 是否删除匿名用户，回车

Disallow root login remotely? [Y/n] <–是否禁止root远程登录,回车,

Remove test database and access to it? [Y/n] <– 是否删除test数据库，回车

Reload privilege tables now? [Y/n] <– 是否重新加载权限表，回车

初始化MariaDB完成，接下来测试登录，输入密码能正常登陆就完成了

mysql -uroot -p

登录数据库root用户执行下面语句：

> create database ambari character set utf8 ;

> CREATE USER 'ambari'@'%'IDENTIFIED BY 'Ambari-123';

> GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';

> FLUSH PRIVILEGES;

> create database hive character set utf8 ;

> CREATE USER 'hive'@'%'IDENTIFIED BY 'Hive-123';

> GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%';

> FLUSH PRIVILEGES;

> create database oozie character set utf8 ;

> CREATE USER 'oozie'@'%'IDENTIFIED BY 'Oozie-123';

> GRANT ALL PRIVILEGES ON *.* TO 'oozie'@'%';

> FLUSH PRIVILEGES;
