Ingredients：

HDP在运行的时候需要用到数据库存放元数据等信息，正如官方文档在Using an existing or installing a default database中所说：

Ambari installs the PostgreSQL, MySQL, and Derby databases for use with Ambari, Hive, and Oozie respectively, as default options. You may instead use a new, or an existing, non-default database instance with these components.

当然可以使用Ambari默认安装的几个数据库，但一般来说会使用MySQL/MariaDB作为数据库使用。这里使用MariaDB。

1 安装MariaDB

鉴于Ambari目前的最新版本：

Ambari 2.7.3
HDP 3.1.0

在Support Matrix中对MariaDB的版本要求是：

MariaDB 10.2

这里就使用MariaDB 10.2.21来安装，可以参考弹指神通MariaDB——CentOS 7.4上安装MariaDB 10.2.21的二进制版本

2 配置MariaDB

配置MariaDB的过程主要是在MariaDB中执行一些官方的数据库脚本，以及创建一些安装软件所需要用到的user、group等。

2.1 Ambari数据配置

2.1.1 指定JDBC的jar位置

2.1.1.1 下载MySQL驱动

Download Connector/J，可以下载Connector/J 5.1.47 - Platform Independent (Architecture Independent)，例如mysql-connector-java-5.1.47.zip。

2.1.1.2 执行脚本命令

执行命令：

ambari-server setup --jdbc-db=mysql --jdbc-driver=/path/to/mysql/mysql-connector-java.jar

2.1.1.3 确认位置

确保jar已经被复制到共享目录：

ls -al /usr/share/java/mysql-connector-java.jar

2.1.1.4 确认权限

确保其权限为644。

2.1.2 创建Ambari的user

使用root登录mysql：

mysql -u root -p

执行脚本：

CREATE USER 'ambari'@'%' IDENTIFIED BY 'ambari';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';
CREATE USER 'ambari'@'localhost' IDENTIFIED BY 'ambari';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'localhost';
CREATE USER 'ambari'@'shizhi004' IDENTIFIED BY 'ambari';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'shizhi004';

2.1.3 创建DATABASE及执行官方脚本

使用Ambari用户登录：

mysql -u ambari -p

执行：

CREATE DATABASE ambari;
USE ambari;
SOURCE /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql;

2.2 Hive的数据配置

参考Using Hive with MySQL

2.2.1 指定JDBC的jar位置

2.2.1.1 运行1

ambari-server setup --jdbc-db=mysql --jdbc-driver=/path/to/mysql/mysql-connector-java.jar

2.2.1.2 确认

ls /usr/share/java/mysql-connector-java.jar

2.2.1.3 权限

权限设为644。

2.2.1.4 运行2

ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar

2.2.2 创建Hive的user

root登录：

mysql -u root -p

执行：

CREATE USER 'hive'@'localhost' IDENTIFIED BY '123456Aaa';
GRANT ALL PRIVILEGES ON *.* TO 'hive'@'localhost';
CREATE USER 'hive'@'%' IDENTIFIED BY '123456Aaa';
GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%';
CREATE USER 'hive'@'shizhi004' IDENTIFIED BY '123456Aaa';
GRANT ALL PRIVILEGES ON *.* TO 'hive'@'shizhi004';

2.2.2 创建Hive的database

root登录：

mysql -u root -p

创建database：

CREATE DATABASE hive；

2.3 Oozie数据配置

同2.2。

2.4 druid的数据配置

同2.2。

2.5 ranger的数据配置

同2.2。

2.6 rangerkms的数据配置

同2.2。

3 汇总脚本

3.1 user

CREATE USER 'ambari'@'%' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';
CREATE USER 'ambari'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'localhost';
CREATE USER 'ambari'@'shizhi004' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'shizhi004';

CREATE USER 'hive'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'hive'@'localhost';
CREATE USER 'hive'@'%' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%';
CREATE USER 'hive'@'shizhi004' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'hive'@'shizhi004';

CREATE USER 'oozie'@'%' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'oozie'@'%';
CREATE USER 'oozie'@'shizhi004' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'oozie'@'shizhi004';

CREATE USER 'druid'@'%' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'druid'@'%';
CREATE USER 'druid'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'druid'@'localhost';
CREATE USER 'druid'@'shizhi004' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'druid'@'shizhi004';

CREATE USER 'ranger'@'%' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'ranger'@'%';
CREATE USER 'ranger'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'ranger'@'localhost';
CREATE USER 'ranger'@'shizhi004' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'ranger'@'shizhi004';

CREATE USER 'rangerkms'@'%' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'rangerkms'@'%';
CREATE USER 'rangerkms'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'rangerkms'@'localhost';
CREATE USER 'rangerkms'@'shizhi004' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'rangerkms'@'shizhi004';

FLUSH PRIVILEGES;

3.2 database

CREATE DATABASE ambari；
CREATE DATABASE hive；
CREATE DATABASE oozie；
CREATE DATABASE druid；
CREATE DATABASE ranger；
CREATE DATABASE rangerkms；

3.3 说明

注意！ 使用的时候还是按产品对应的执行脚本，而不要放在一起执行，这里将脚本放到了一起主要是为了查阅方便。
