Setting up the database and users

...

1. Download, install and start MariaDB on your computer. See https://downloads.mariadb.org/.

   Info
   You can install MariaDB standalone or as a galera cluster for high availability. Database clustering is independent of WSO2 product clustering. For more information on setting up a galera cluster, see the MariaDB Galera Cluster documentation.

   Info
   For instructions on installing MariaDB on MAC OS, go to Homebrew.

2. Log in to MariaDB as the root user (or any other user with database creation privileges).
   

   mysql -u root -p

3. Enter the password when prompted.

   Info
   In most systems, there is no default root password. Press the Enter key without typing anything if you have not changed the default root password.

4. In the MySQL command prompt, create the database using the following command:
   

   create database regdb;

5. Give authorization of the database to the regadmin user as follows:
   

   GRANT ALL ON regdb.* TO regadmin@localhost IDENTIFIED BY "regadmin";

6. Once you have finalized the permissions, reload all the privileges by executing the following command:
   

   FLUSH PRIVILEGES;

7. Log out from the MySQL prompt by executing the following command:
   

   quit;

Download the MySQL Java connector JAR file, and copy it to the <PRODUCT_HOME>/repository/components/lib/ directory.

1. Edit the default datasource configuration in the <PRODUCT_HOME>/repository/conf/datasources/m aster-datasources.xml file as shown below.

   Note
   Do not change the datasource name WSO2_CARBON_DB in the below configuration.

   Code Block
   language html/xml
   <datasource> <name>WSO2_CARBON_DB</name> <description>The datasource used for registry and user manager</description> <jndiConfig> <name>jdbc/WSO2CarbonDB</name> </jndiConfig> <definition type="RDBMS"> <configuration> <url>jdbc:mysql://localhost:3306/regdb</url> <username>regadmin</username> <password>regadmin</password> <defaultAutoCommit>false</defaultAutoCommit> <driverClassName>com.mysql.jdbc.Driver</driverClassName> <maxActive>80</maxActive> <maxWait>60000</maxWait> <minIdle>5</minIdle> <testOnBorrow>true</testOnBorrow> <validationQuery>SELECT 1</validationQuery> <validationInterval>30000</validationInterval> </configuration> </definition> </datasource>

   The elements in the above configuration are described below:

   Element	Description
   url	The URL of the database. The default port for MariaDB is 3306
   username and password	The name and password of the database user
   driverClassName	The class name of the database driver
   maxActive	The maximum number of active connections that can be allocated  at the same time from this pool. Enter any negative value to denote an unlimited number of active connections.
   maxWait	The maximum number of milliseconds that the pool will wait (when there are no available connections) for a connection to be returned before throwing an exception. You can enter zero or a negative value to wait indefinitely.
   minIdle	The minimum number of active connections that can remain idle in the pool without extra ones being created, or enter zero to create none.
   testOnBorrow	The indication of whether objects will be validated before being borrowed from the pool. If the object fails to validate, it will be dropped from the pool, and another attempt will be made to borrow another.
   validationQuery	The SQL query that will be used to validate connections from this pool before returning them to the caller.
   validationInterval	The indication to avoid excess validation, and only run validation at the most, at this frequency (time in milliseconds). If a connection is due for validation, but has been validated previously within this interval, it will not be validated again.

   Info
   For more information on other parameters that can be defined in the <PRODUCT_HOME>/repository/conf/datasources/ master-datasources.xml file, see Tomcat JDBC Connection Pool.
