Using Ambari with MySQL/MariaDB

« Prev

To set up MySQL for use with Ambari:

On the Ambari Server host, install the connector.
1. Install the connector
  RHEL/CentOS/Oracle Linux
  yum install mysql-connector-java
  SLES
  zypper install mysql-connector-java
  Debian/Ubuntu
  apt-get install libmysql-java
2. Confirm that .jar is in the Java share directory.
  ls /usr/share/java/mysql-connector-java.jar
3. Make sure the .jar file has the appropriate permissions - 644.
Create a user for Ambari and grant it permissions.
- For example, using the MySQL database admin utility:
  # mysql -u root -p
  CREATE USER '<AMBARIUSER>'@'%' IDENTIFIED BY '<AMBARIPASSWORD>';
  GRANT ALL PRIVILEGES ON *.* TO '<AMBARIUSER>'@'%';
  CREATE USER '<AMBARIUSER>'@'localhost' IDENTIFIED BY '<AMBARIPASSWORD>';
  GRANT ALL PRIVILEGES ON *.* TO '<AMBARIUSER>'@'localhost';
  CREATE USER '<AMBARIUSER>'@'<AMBARISERVERFQDN>' IDENTIFIED BY '<AMBARIPASSWORD>';
  GRANT ALL PRIVILEGES ON *.* TO '<AMBARIUSER>'@'<AMBARISERVERFQDN>';
  FLUSH PRIVILEGES;
- Where <AMBARIUSER> is the Ambari user name, <AMBARIPASSWORD> is the Ambari user password and <AMBARISERVERFQDN> is the Fully Qualified Domain Name of the Ambari Server host.
Load the Ambari Server database schema.
- You must pre-load the Ambari database schema into your MySQL/MariaDB database using the schema script.
  mysql -u <AMBARIUSER> -p
  CREATE DATABASE <AMBARIDATABASE>;
  USE <AMBARIDATABASE>;
  SOURCE Ambari-DDL-MySQL-CREATE.sql;
- Where <AMBARIUSER> is the Ambari user name and <AMBARIDATABASE> is the Ambari database name.
  Find the Ambari-DDL-MySQL-CREATE.sql file in the /var/lib/ambari-server/resources/ directory of the Ambari Server host after you have installed Ambari Server.
When setting up the Ambari Server, select Advanced Database Configuration > Option [3] MySQL/MariaDB and enter the credentials you defined in Step 2. for user name, password and database name.
