This section describes how to install the MySQL database server, after which you can create and initialize the databases and their users.

For more information on supported versions of this database type, see System Requirements in the Planning Guide.

Pre-requisites

The installing user must have write permissions to the directory from which the commands are executed.
The installing user must have sudo privileges.

Acquire MySQL Java driver

The MySQL Java driver is not packaged with the . If you are installing the into MySQL, please acquire the following driver files.

File 1:

mysql-connector-java-6.0.6.jar

This file can be downloaded from the following locations:

This file needs to be installed in the following locations on the :

/opt/trifacta/services/artifact-storage-service/build/install/artifact-storage-service/lib/mysql-connector-java-6.0.6.jar

This file needs to be installed in the following location:

Select Configuration File

If you are installing the database in a MySQL instance, a separate base configuration has been provided. This configuration file is stored in the following location:

/opt/trifacta/conf/trifacta-conf.json.MYSQL_DB

To use MySQL, you should back up the default configuration file and then copy the MySQL version in its place:

If you have already applied configuration changes to through the above file or the Admin Settings page, these changes are lost when the following steps are performed. You must manually migrate those changes over or apply the MySQL changes manually.

cp /opt/trifacta/conf/trifacta-conf.json /opt/trifacta/conf/trifacta-conf.json.POSTGRES_DB
cp /opt/trifacta/conf/trifacta-conf.json.MYSQL_DB /opt/trifacta/conf/trifacta-conf.json

Acquire Port Information

After you have completed the installation, you must acquire the port information for each database from the following locations on the . These port numbers need to be applied inside the .

CentOS/RHEL (MySQL 5.7):

The default port is 3306.

Ubuntu (MySQL 5.7) : Not supported.

Configure MySQL Timezone

If your MySQL databases are in a different timezone from the , you must configure the timezone value for each database, so that it can be inserted as part of the connection string.

NOTE: If the and your MySQL databases are co-located in the same timezone, you can skip this section.

In the Admin Settings page, these parameters are in the following form:

"*.database.mySqlServerTimezone": "",

For each database, insert the appropriate timezone value. For more information on supported values, see the documentation for your MySQL product.

See Database Parameter Reference.

Update MySQL Password Policy

NOTE: This section only applies to CentOS and RHEL platforms only where MySQL is the installed database.

By default, MySQL enforces a stricter password policy on database passwords. If you prefer to set your own passwords outside of this policy, you must lower the password policy. Please complete the following steps:

# Get temporary root password from mysql log
sudo grep 'temporary password' /var/log/mysqld.log
# Connect to server as root
mysql -uroot -p
# Update password
ALTER USER 'root'@'localhost' IDENTIFIED BY '<my_new_password>';
# Unless you plan to update all the User passwords to be meet MySql Security requirements, you should set the password policy to low
SET GLOBAL validate_password_policy=LOW;
