二、 环境准备
1、主机172.19.80.2 SY-001.hadoop172.19.80.3 SY-002.hadoop172.19.80.4 SY-003.hadoop172.19.80.5 ambari-mysql2、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 -y（3）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_112export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jarPATH=$PATH:$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NSCDambari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/hosts172.19.80.2 SY-001.hadoop172.19.80.3 SY-002.hadoop172.19.80.4 SY-003.hadoop172.19.80.5 ambari-mysql（7）每台节点里配置FQDN，如下以主节点为例$ cat /etc/sysconfig/networkNETWORKING=yesHOSTNAME=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/selinuxSELINUX=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 = MariaDBbaseurl = http://yum.mariadb.org/10.1/centos7-amd64gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDBgpgcheck=1After the file is in place, install MariaDB with:$ sudo yum install MariaDB-server MariaDB-clientIf 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 - Updatesbaseurl=http://172.19.80.2/ambari/AMBARI-2.4.2.0/centos7/2.4.2.0-136gpgcheck=1gpgkey=http://172.19.80.2/ambari/AMBARI-2.4.2.0/centos7/2.4.2.0-136/RPM-GPG-KEY/RPM-GPG-KEY-Jenkinsenabled=1priority=1$ cat hdp.repo#VERSION_NUMBER=2.5.3.0[HDP-2.5.3.0]name=HDP Version - HDP-2.5.3.0baseurl=http://172.19.80.2/ambari/HDP/centos7/2.x/updates/2.5.3.0gpgcheck=1gpgkey=http://172.19.80.2/ambari/HDP/centos7/2.x/updates/2.5.3.0/RPM-GPG-KEY/RPM-GPG-KEY-Jenkinsenabled=1priority=1[HDP-UTILS-1.1.0.21]name=HDP Utils Version - HDP-UTILS-1.1.0.21baseurl=http://172.19.80.2/ambari/HDP-UTILS-1.1.0.21/repos/centos7gpgcheck=1gpgkey=http://172.19.80.2/ambari/HDP/centos7/2.x/updates/2.5.0.0/RPM-GPG-KEY/RPM-GPG-KEY-Jenkinsenabled=1priority=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：yCustomize user account for ambari-server daemon [y/n] (n)? y（2）ambari-server 账号。输入：ambariEnter user account for ambari-server daemon (root):ambariAdjusting ambari-server permissions and ownership...（3）设置JDK。输入：3Checking JDK...Do you want to change Oracle JDK [y/n] (n)? y[] Oracle JDK 1.8 + Java Cryptography Extension (JCE) Policy Files 8[] Oracle JDK 1.7 + Java Cryptography Extension (JCE) Policy Files 7[] Custom JDK==============================================================================Enter choice (1): 3（4）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_112WARNING: 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.Path to JAVA_HOME: /opt/java/jdk1.8.0_112Validating JDK on Ambari Server...done.Completing setup...（5）数据库配置。选择：yConfiguring database...Enter advanced database configuration [y/n] (n)? y（6）选择数据库类型。输入：3Configuring database...==============================================================================Choose one of the following options:[1] - PostgreSQL (Embedded)[2] - Oracle[3] - MySQL[4] - PostgreSQL[5] - Microsoft SQL Server (Tech Preview)[6] - SQL Anywhere==============================================================================Enter choice (3): 3（7）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):Username (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mysqlmysql -u ambari -puse ambarisource /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql（9）启动Amabri$ ambari-server start（10）成功启动后在浏览器输入Ambari地址：http://sy-001.hadoop:8080/ |
六、使用Ambari界面安装Hadoop、Hbase、Log Search服务
1、出现登录界面，默认管理员账户登录， 账户：admin 密码：admin
2、登录成功后出现下面的界面，至此Ambari的安装成功
3、安装安装HDP 2.5.3 配置集群（点击上面登录成功页面的Launch Install Wizard 按钮进行集群配置）
设置集群名称
4、置HDP安装源（选择HDP2.5 ,并且设置Advanced Repository Options 的信息，本次使用本地源，所以修改对用系统的安装源为本地源地址）
123 | 选择RedHat7,填写下面源链接HDP-2.5: http://172.19.80.2/ambari/HDP/centos7/2.x/updates/2.5.3.0HDP-UTILS-1.1.0.21: http://172.19.80.2/ambari/HDP-UTILS-1.1.0.21/repos/centos7 |
5、设置集群机器（下载SY-001.hadoop机器上的id_rsa私钥到本地）
6、Host确认（确认前面配置集群中hosts列表 中的机器是否都可用，也可以移除相关机器，集群中机器Success后进行下一步操作）
7、选择要安装的服务
8、各个服务Master配置
9、服务的Slaves 和 Clients节配置
10、服务的客制化配置
11、显示配置信息
12、开始安装（安装各个服务，并且完成安装后会启动相关服务，安装过程比较长，如果中途出现错误，请根据具体提示或者log进行操作）
13、全部安装成功界面如下
14、安装完成
七、Hadooop开启高可用（现在安装好Hadoop是不支高可用的，下面准备开启Hadoop高可用）
1、开启高可用开关
2、设置高可用名称（如果hbase是启动的话请关闭在开启HA高可用）
3、选择服务安装在那台主机上
4、按照提示操作，最后显示如下表示HA安装成功
5、Hbase高可用会显示如下图
