1. 介绍
1.1 Ambari
- Ambari 跟 Hadoop 等开源软件一样，也是 Apache Software Foundation 中的一个项目，并且是顶级项目。就 Ambari 的作用来说，就是创建、管理、监视 Hadoop 的集群，但是这里的 Hadoop 指的是 Hadoop 整个生态圈（例如 Hive，Hbase，Sqoop，Zookeeper 等）， 而并不仅是特指 Hadoop。用一句话来说，Ambari 就是为了让 Hadoop 以及相关的大数据软件更容易使用的一个工具。
- Ambari 自身也是一个分布式架构的软件，主要由两部分组成：Ambari Server 和 Ambari Agent。简单来说，用户通过 Ambari Server 通知 Ambari Agent 安装对应的软件；Agent 会定时地发送各个机器每个软件模块的状态给 Ambari Server，最终这些状态信息会呈现在 Ambari 的 GUI，方便用户了解到集群的各种状态，并进行相应的维护。
1.2 HDP
- HDP是hortonworks的软件栈，里面包含了hadoop生态系统的所有软件项目，比如HBase,Zookeeper,Hive,Pig等等。
1.3 HDP-UTILS
- HDP-UTILS是工具类库。
2. 准备工作

- 启动mysql并设置开机自启
systemctl start mysqld.service # 启动mysql
systemctl status mysqld.service # 查看mysql状态
systemctl stop mysqld.service # 关闭mysql
systemctl enable mysqld.service # 开机自启
- 重置密码【root/root123】：mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none): # 输入enter
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
Set root password? [Y/n] y # [设置root用户密码]
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y # [删除匿名用户]
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] n # [禁止root远程登录]
... skipping.
By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y # [删除test数据库]
- Dropping test database...
ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist
... Failed! Not critical, keep moving...
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y # [刷新权限]
... Success!
All done! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!
Cleaning up...
- 授权登录
grant all privileges on *.* to 'root'@'%';
flush privileges;
- 配置mysql编码，字符格式：vim /etc/my.cnf
- 重启mysql服务：systemctl restart mysqld.service
- 查看字符集： show variables like ‘character_set_%’;
3.3.4 在mysql数据库创建相应的用户和DB
- 创建ambari数据库及数据库的用户名和密码
mysql> create database ambari character set utf8;
Query OK, 1 row affected (0.00 sec)
mysql> CREATE USER 'ambari'@'%'IDENTIFIED BY 'Ambari123';
Query OK, 0 rows affected (0.00 sec)
mysql> GRANT ALL PRIVILEGES ON ambari.* TO 'ambari'@'%';
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)
- 创建hive数据库及hive库的用户名和密码
mysql> create database hive character set utf8;
Query OK, 1 row affected (0.00 sec)
mysql> CREATE USER 'hive'@'%'IDENTIFIED BY 'Hive123';
Query OK, 0 rows affected (0.00 sec)
mysql> GRANT ALL PRIVILEGES ON hive.* TO 'hive'@'%';
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)
- 创建oozie数据库及oozie库的用户名和密码
mysql> create database oozie character set utf8;
Query OK, 1 row affected (0.00 sec)
mysql> CREATE USER 'oozie'@'%'IDENTIFIED BY 'Oozie123';
Query OK, 0 rows affected (0.00 sec)
mysql> GRANT ALL PRIVILEGES ON oozie.* TO 'oozie'@'%';
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)
- 下载mysql-connection-java：
yum install mysql-connector-java
- 查看下载后的jar包，看目录中是否有mysql-connector-java:
ls /usr/share/java
3.3.5 免密登录
- nd-00.hdp ⇒ 00，01，02的免密登录：
[root@nd-00 ~]# ssh-keygen -t rsa # 一路回车
[root@nd-00 ~]# ssh-copy-id nd-00.hdp # 输入密码
[root@nd-00 ~]# ssh-copy-id nd-01.hdp # 输入密码
[root@nd-00 ~]# ssh-copy-id nd-02.hdp # 输入密码
- nd-01.hdp ⇒ 01，02的免密登录：
[root@nd-01 ~]# ssh-keygen -t rsa # 一路回车
[root@nd-01 ~]# ssh-copy-id nd-01.hdp # 输入密码
[root@nd-01 ~]# ssh-copy-id nd-02.hdp # 输入密码
4. 在yum.hdp上安装Ambari
4.1 安装yum相关工具
[root@yum ~]# yum install yum-utils -y
[root@yum ~]# yum repolist
[root@yum ~]# yum install createrepo -y
4.2 安装Apache httpd
- 使用yum在线安装httpd：上传下载文件（借助xftp工具）
[root@yum ~]# yum install httpd -y
- 安装完成后，会生成 /var/www/html目录（相当于Tomcat的webapps目录），进入到/var/www/html目录下，创建ambari和hdp目录，用来存放安装文件。
[root@yum ~]# mkdir /var/www/html/ambari
[root@yum ~]# mkdir /var/www/html/hdp
[root@yum ~]# mkdir /var/www/html/hdp/HDP-UTILS-1.1.0.21
[root@yum ~]# tar -zxvf ambari-2.5.2.0-centos7.tar.gz -C /var/www/html/ambari/
[root@yum ~]# tar -zxvf HDP-2.6.2.0-centos7-rpm.tar.gz -C /var/www/html/hdp/
[root@yum ~]# tar -zxvf HDP-UTILS-1.1.0.21-centos7.tar.gz -C /var/www/html/hdp/HDP-UTILS-1.1.0.21/
- 启动httpd服务：
[root@yum ~]# systemctl start httpd # 启动httpd
[root@yum ~]# systemctl status httpd # 查看httpd状态
[root@yum ~]# systemctl enable httpd # 设置httpd开机自启
- 默认端口80，浏览器输入：http://192.168.120.77
4.3 配置本地 Repo
4.3.1 配置Ambari
- 下载
wget -nv http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.5.2.0/ambari.repo -O /etc/yum.repos.d/ambari.repo
- 修改配置文件：vim /etc/yum.repos.d/ambari.repo
4.3.1 配置HDP和HDP-UTILS
- 创建配置文件：[root@yum yum.repos.d]# touch /etc/yum.repos.d/HDP.repo
- 添加内容
#VERSION_NUMBER=2.6.2.0
[HDP-2.6.2.0]
name=HDP Version - HDP-2.6.2.0
baseurl=http://192.168.120.77/hdp/HDP/centos7/
gpgcheck=1
gpgkey=http://192.168.120.77/hdp/HDP/centos7/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins

4.3.2 分发Ambari.repo和HDP.repo
- 把ambari.repo HDP.repo分发到各个节点的相同目录下
[root@yum yum.repos.d]# scp ambari.repo HDP.repo nd-00.hdp:$PWD
[root@yum yum.repos.d]# scp ambari.repo HDP.repo nd-01.hdp:$PWD
[root@yum yum.repos.d]# scp ambari.repo HDP.repo nd-02.hdp:$PWD
4.3.3 生成本地源
- 使用createrepo命令，创建yum本地源（软件仓库），即为存放本地特定位置的众多rpm包建立索引，描述各包所需依赖信息，并形成元数据。
[root@yum ~]# createrepo /var/www/html/hdp/HDP/centos7/

5.2 启动Ambari-Server
- 如果启动失败，关闭服务【ambari-server stop】，重新启动
[root@nd-00 ~]# ambari-server start
Using python /usr/bin/python
Starting ambari-server
Ambari Server running with administrator privileges.
Organizing resource files at /var/lib/ambari-server/resources...
Ambari database consistency check started...
Server PID at: /var/run/ambari-server/ambari-server.pid
Server out at: /var/log/ambari-server/ambari-server.out
Server log at: /var/log/ambari-server/ambari-server.log
Waiting for server start.................................
Server started listening on 8080
DB configs consistency check: no errors and warnings were found.
Ambari Server 'start' completed successfully.
5.3 安装Agent
- nd-00/01/02.hdp 所有节点安装ambari-agent
yum -y install ambari-agent
5.4 访问Ambari web页面
- 默认端口8080，Username：admin；Password：admin；http://192.168.120.100:8080
6. 开始安装集群
- 启用安装向导创建集群，并起一个名字
- 选择版本
- 配置节点、密钥
- 主机确认
- 选择大数据组件
- 节点分配
- 分配从属和客户端
- 配置组件
- Hive配置，测试与mysql的链接
[root@nd-00 ~]# ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar
- Ambari Metrics，SmartSense
- 集群整体概况，点击部署
- 等待启动完毕，不用担心警告，后期可以调整，搭建完成，可以在展示页面进行查看集群状态。
- 可以查看监控界面，可以看到大数据组件中出现错误，单个组件点开处理，由于本次搭建集群使用虚拟机，性能不好，可以少选择一些组件。
