MySQL version 5.7 or greater is required.

1 Install Notes
2 Installation
3 Configuration
- 3.1 Run the Create Script MySQL 8
- 3.2 Run the Create Script MySQL 5.7
4 Set MySQL to Start on Boot

Install Notes

Included in the installation package is a file named mysql-create.sql; log into the main database and execute these commands. Also included is a file named mysql-create-metadata.sql; log into the metadata database and execute these commands.

Note: For MySQL the database must be configured with the UTF8 character set. For MySQL 8 utf8mb4 and utf8mb4_unicode_ci are supported as well. Currently, other character sets and collations are not supported.

Installation

We highly recommend installing MySQL on a dedicated database server. To communicate with MySQL on that server completing this installation will require the username, password, hostname and port (e.g. 3306).

Configuration

Configuring MySQL can be necessary to ensure optimal performance. These options are not required but could help with performance.
