1.系統版本

[root@manager ~]# cat /etc/centos-release
CentOS Linux release 7.4.1708 (Core)

2.主機規劃

3.軟件版本

ambari-2.4.3.0-centos7.tar.gz
HDP-2.5.3.0-centos7-rpm.tar.gz
HDP-UTILS-1.1.0.21-centos7.tar.gz

二、環境準備（所有節點上都要配置）

1.修改主機名

2.防火墻和selinux

[root@manager ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)
[root@manager ~]# getenforce 
Disabled
[root@manager ~]#

3.配置hosts文件

[root@manager ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.10.128 vm1
192.168.10.129 vm2
192.168.10.130 vm3
192.168.10.131 manager

4.配置SSH免密碼登陸

5.關閉linux的THP服務

#在GRUB_CMDLINE_LINUX這一行後面添加transparent_hugepage=never，如下
[root@manager ~]# cat /etc/default/grub 
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet transparent_hugepage=never"
GRUB_DISABLE_RECOVERY="true"
#執行以下命令
[root@manager ~]# grub2-mkconfig -o /boot/grub2/grub.cfg
[root@manager ~]# systemctl disable tuned
#重啟後顯示如下
[root@manager ~]# cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]
[root@manager ~]# grep AnonHugePages /proc/meminfo  
AnonHugePages:         0 kB
[root@manager ~]#

6.配置UMASK

[root@manager ~]# umask 0022
[root@manager ~]# umask
0022

7.配置時間同步NTP

[root@manager ~]# yum -y install ntp
[root@manager ~]# systemctl start ntpd
[root@manager ~]# systemctl enable ntpd

8.安裝JDK並配置JAVA_HOME環境變量

三、安裝Ambari集群（只在manager上配置)

1.安裝HTTP服務

[root@manager ~]# yum install -y httpd
[root@manager ~]# systemctl start httpd
[root@manager ~]# systemctl enable httpd

2.安裝MySQL

3.配置MySQL

#mysql有密碼復雜度要求，如果不需要密碼策略在/etc/my.cnf文件中添加如下配置並重啟mysql即可禁用
validate_password = off
systemctl restart mysqld
#查看mysql的初始默認密碼
[root@manager ~]# cat /var/log/mysqld.log | grep password
2017-12-13T01:49:55.629403Z 1 [Note] A temporary password is generated for root@localhost: 3aYp&Zsqq7Ov
#使用初始密碼進入mysql修改密碼
ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
#在mysql中創建ambari數據庫及用戶
CREATE DATABASE ambari CHARACTER SET utf8 ;  
CREATE USER 'ambari'@'%'IDENTIFIED BY '123456';
CREATE USER 'ambari'@'local'IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';
FLUSH PRIVILEGES;
#創建hive和其它數據庫也類似

4.下載Ambari和HDP

wget -nv http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.4.3.0/ambari-2.4.3.0-centos7.tar.gz
wget -nv 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 -nv http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.21/repos/centos7/HDP-UTILS-1.1.0.21-centos7.tar.gz

5.解壓至httpd目錄下

[root@manager ~]# mkdir /var/www/html/ambari 
[root@manager ~]# mkdir /var/www/html/ambari/HDP-UTILS
tar zxvf ambari-2.4.3.0-centos7.tar.gz -C /var/www/html/ambari
tar zxvf HDP-2.5.3.0-centos7-rpm.tar.gz -C /var/www/htmlambari
tar zxvf HDP-UTILS-1.1.0.21-centos7.tar.gz -C /var/www/html/ambari/HDP-UTILS

6.安裝本地源制作相關工具

[root@manager ~]# yum install -y yum-utils createrepo yum-plugin-priorities
[root@manager ~]# vim /etc/yum/pluginconf.d/priorities.conf 

[main]
enabled = 1
gpgcheck=0

[root@manager data]# cd /var/www/html/ambari
[root@manager ambari]# createrepo  ./

7.配置本地源

[root@manager ~]# cat /etc/yum.repos.d/ambari.repo 
[ambari-2.4.3.0]
name=ambari-2.4.3.0
baseurl=http://manager/ambari/AMBARI/
gpgcheck=1
gpgkey=http://manager/ambari/AMBARI/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1

[root@manager ~]# cat /etc/yum.repos.d/hdp.repo 
[HDP-2.5.3.0]
name=HDP
baseurl=http://manager/ambari/HDP/centos7/
gpgcheck=1
gpgkey=http://manager/ambari/HDP/centos7/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1

[HDP-UTILS-1.1.0.21]
name=HDP-UTILS
baseurl=http://manager/ambari/HDP-UTILS/
gpgcheck=1
gpgkey=http://manager/ambari/HDP-UTILS/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1

[root@manager ~]# yum clean all
[root@manager ~]# yum makecache
#查看ambari和hdp的資源庫
[root@manager ~]# yum repolist
repo id                                                          repo name                                                  status
HDP-2.5.3.0                                                      HDP                                                             200
HDP-UTILS-1.1.0.21                                               HDP-UTILS                                                        64
ambari-2.4.3.0                                                   ambari-2.4.3.0

8.安裝ambari和mysql驅動

[root@manager ~]# yum install -y ambari
[root@manager ~]# yum install -y mysql-connector-java

9.配置ambari

[root@manager ~]# ambari-server setup

10.使用msyql用戶ambari在ambari數據庫中導入數據

source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql

11.啟動ambari

[root@manager ~]# ambari-server start
#在瀏覽器中輸入ambari地址
http://192.168.10.131:8080
