二、 环境准备

1、主机
172.19.80.2 SY-001.hadoop
172.19.80.3 SY-002.hadoop
172.19.80.4 SY-003.hadoop
172.19.80.5 ambari-mysql

2、安装基础环境 (在主机SY-001.hadoop,SY-002.hadoop,SY-003.hadoop部署)
(1)安装基本包
$ yum install openssh wget vim openssh-clients openssl gcc openssh-server mysql-connector-odbc -y
$ systemctl enable sshd && systemctl start sshd

(2)安装mysql jdbc 驱动
$ yum install mysql-connector-java -y3)安装JDK
版本要求:
Oracle JDK 1.8 64-bit (minimum JDK 1.8.0_77) (default)
Oracle JDK 1.7 64-bit (minimum JDK 1.7_67)
OpenJDK 8 64-bit (not supported on SLES)
OpenJDK 7 64-bit (not supported on SLES)

$ mkdir /usr/local/src/Ambari/
$ wget http://download.oracle.com/otn-pub/java/jdk/8u112-b15/jdk-8u112-linux-x64.tar.gz?AuthParam=1480914946_a78f7ba2e70d2f0abed0b0af73c74214
$ mkdir -p /opt/java/ && tar xf jdk-8u112-linux-x64.tar.gz -C /opt/java
$ vim /etc/profile
添加下面内容:
export JAVA_HOME=/opt/java/jdk1.8.0_112
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
$ source /etc/profile

(4)配置SSH免密码登录
主节点里root用户登录执行如下步骤
$ ssh-keygen
$ cd ~/.ssh/
$ cat id_rsa.pub >> authorized_keys
$ chmod 600 ~/.ssh/authorized_keys
把各个主机上公钥id_rsa.pub文件内容放到各个主机authorized_keys中

(5)开启NTP服务
$ yum -y install ntp
$ systemctl is-enabled ntpd
$ systemctl enable ntpd
$ systemctl start ntpd

(6)检查DNS和NSCD
ambari在安装时需要配置全域名,所以需要检查DNS。为了减轻DNS的负担, 建议在节点里用 Name Service Caching Daemon (NSCD)
$ cat /etc/hosts
172.19.80.2 SY-001.hadoop
172.19.80.3 SY-002.hadoop
172.19.80.4 SY-003.hadoop
172.19.80.5 ambari-mysql7)每台节点里配置FQDN,如下以主节点为例
$ cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=SY-001.hadoop

(8)关闭防火墙和SELinux
$ systemctl disable firewalld
$ systemctl stop firewalld
临时关闭,不用重启机器:
$ setenforce 0
修改配置文件让机器重启也生效:
$ cat /etc/sysconfig/selinux
SELINUX=disabled

三、搭建数据库(在主机ambari-mysql上部署)

Ambari安装会将安装等信息写入数据库,建议使用自己安装的Mysql数据库,也可以不安装而使用默认数据库PostgreSQL

版本要求:
- PostgreSQL 8
- PostgreSQL 9.1.13+,9.3, 9.4***
- MariaDB 10*
- MySQL 5.6
- Oracle 11gr2
- Oracle 12c**

按你系统来选择源:http://downloads.mariadb.org/mariadb/repositories/

Here is your custom MariaDB YUM repository entry for CentOS. Copy and paste it into a file under /etc/yum.repos.d/ (we suggest naming the file MariaDB.repo or something similar).

# MariaDB 10.1 CentOS repository list - created 2016-12-09 06:03 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
After the file is in place, install MariaDB with:

$ sudo yum install MariaDB-server MariaDB-client
If you haven't already accepted the MariaDB GPG key, you will be prompted to do so. See "Installing MariaDB with yum" for detailed information.

安装完成后创建ambari数据库及用户,登录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;

如果要安装Hive,再创建Hive数据库和用户 再执行下面的语句:
create database hive character set utf8 ;  
CREATE USER 'hive'@'%'IDENTIFIED BY 'Hive-123';
GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%';
FLUSH PRIVILEGES;

如果要安装Oozie,再创建Oozie数据库和用户 再执行下面的语句:
create database oozie character set utf8 ;  
CREATE USER 'oozie'@'%'IDENTIFIED BY 'Oozie-123';
GRANT ALL PRIVILEGES ON *.* TO 'oozie'@'%';
FLUSH PRIVILEGES;

四、制作本地源 (在SY-001.hadoop部署)

下载 Ambari HDP HDP-UTILS 源包(文件很大,需要很长下载时间,请耐心等待。。。)
$ cd /usr/local/src/Ambari/
$ wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.4.2.0/ambari-2.4.2.0-centos7.tar.gz
$ wget http://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.5.3.0/HDP-2.5.3.0-centos7-rpm.tar.gz
$ wget http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.21/repos/centos7/HDP-UTILS-1.1.0.21-centos7.tar.gz

安装本地源制作相关工具
$ yum install yum-utils createrepo -y

安装httpd服务
$ yum install httpd -y
$ systemctl enable httpd && systemctl start httpd
$ cd /var/www/html/ && mkdir ambari
$ cd /usr/local/src/Ambari/
$ tar xf ambari-2.4.2.0-centos7.tar.gz -C /var/www/html/ambari/
$ tar xf HDP-2.5.3.0-centos7-rpm.tar.gz -C /var/www/html/ambari/
$ tar xf HDP-UTILS-1.1.0.21-centos7.tar.gz -C /var/www/html/ambari/

验证httd网站是否可用,可以使用links 命令或者浏览器直接访问下面的地址:
$ links http://172.19.80.2/ambari/
结果是看到刚才解压的目录

配置ambari、HDP、HDP-UTILS的本地源
首先下载上面资源列表中的相应repo文件,修改其中的URL为本地的地址,相关配置如下:
$ cd /etc/yum.repos.d/
$ cat ambari.repo
#VERSION_NUMBER=2.4.2.0-136
[Updates-ambari-2.4.2.0]
name=ambari-2.4.2.0 - Updates
baseurl=http://172.19.80.2/ambari/AMBARI-2.4.2.0/centos7/2.4.2.0-136
gpgcheck=1
gpgkey=http://172.19.80.2/ambari/AMBARI-2.4.2.0/centos7/2.4.2.0-136/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1

$ cat hdp.repo
#VERSION_NUMBER=2.5.3.0
[HDP-2.5.3.0]
name=HDP Version - HDP-2.5.3.0

enabled=1
priority=1

[HDP-UTILS-1.1.0.21]
name=HDP Utils Version - HDP-UTILS-1.1.0.21
baseurl=http://172.19.80.2/ambari/HDP-UTILS-1.1.0.21/repos/centos7
gpgcheck=1
gpgkey=http://172.19.80.2/ambari/HDP/centos7/2.x/updates/2.5.0.0/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1

$ yum clean all
$ yum makecache
$ yum repolist

五、安装Ambari (在SY-001.hadoop部署)

安装Ambari
$ yum install ambari-server -y

配置Ambari
$ ambari-server setup

下面是配置执行流程,按照提示操作
(1) 提示是否自定义设置。输入:y
Customize user account for ambari-server daemon [y/n] (n)? y

(2)ambari-server 账号。输入:ambari
Enter user account for ambari-server daemon (root):ambari
Adjusting ambari-server permissions and ownership...

(3)设置JDK。输入:3
Checking JDK...

[] Custom JDK
==============================================================================
Enter choice (1): 34)如果上面选择3自定义JDK,则需要设置JAVA_HOME。输入:/opt/java/jdk1.8.0_112
WARNING: JDK must be installed on all hosts and JAVA_HOME must be valid on all hosts.
WARNING: JCE Policy files are required for configuring Kerberos security. If you plan to use Kerberos,please make sure JCE Unlimited Strength Jurisdiction Policy Files are valid on all hosts.

==============================================================================
Enter choice (3): 37)设置数据库的具体配置信息,根据实际情况输入,如果和括号内相同,则可以直接回车。
Hostname (localhost):
Port ():
Database name (ambari):

Enter Database Password (Ambari-123):

(8)将Ambari数据库脚本导入到数据库
如果使用自己定义的数据库,必须在启动Ambari服务之前导入Ambari的sql脚本

用Ambari用户(上面设置的用户)登录mysql
mysql -u ambari -p
use ambari
source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql9)启动Amabri
$ ambari-server start10)成功启动后在浏览器输入Ambari地址:
http://sy-001.hadoop:8080/
