Install and start MySQL 5.x.

(See "Metastore Database Requirements" and "Installing and Configuring MySQL" in Chapter 1 of this guide.)

Create the Oozie database and Oozie MySQL user.

For example, using the MySQL mysql command-line tool:

$ mysql -u root -p
Enter password: ******

mysql> create database oozie;
Query OK, 1 row affected (0.03 sec)

mysql> grant all privileges on oozie.* to 'oozie'@'localhost' identified by 'oozie';
Query OK, 0 rows affected (0.03 sec)

mysql> grant all privileges on oozie.* to 'oozie'@'%' identified by 'oozie';
Query OK, 0 rows affected (0.03 sec)

mysql> exit
Bye 

The parameter "identified by 'oozie'" sets the password for the oozie user to use "oozie". Choose a secure password for this account and add it to the oozie-site.xml file under oozie.service.JPAService.jdbc.password.

Configure Oozie to use MySQL.

<property>
     <name>oozie.service.JPAService.jdbc.driver</name>
     <value>com.mysql.jdbc.Driver</value>
</property>

<property>
     <name>oozie.service.JPAService.jdbc.url</name>
     <value>jdbc:mysql://localhost:3306/oozie</value>
</property>

<property>
     <name>oozie.service.JPAService.jdbc.username</name>
     <value>oozie</value>
</property>

<property>
     <name>oozie.service.JPAService.jdbc.password</name>
     <value>oozie</value>
</property> 

	Note
	In the JDBC URL property, replace localhost with the hostname where MySQL is running.

Add the MySQL JDBC driver JAR to Oozie:

Copy or symlink the MySQL JDBC driver JAR into the /var/lib/oozie/ directory.

	Note
	You must manually download the MySQL JDBC driver JAR file.
