By default, the MariaDB database service is configured when you deploy a Distributed DDNS Data Node. You can modify the configuration information through the MariaDB service configuration.

  1. Click the Settings icon under the MariaDB column.
  2. In the configuration window, the following information appears:
    # MariaDB database server configuration file.
    #
    # You can copy this file to one of:
    # - "/etc/mysql/my.cnf" to set global options,
    # - "~/.my.cnf" to set user-specific options.
    # 
    # One can use all long options that the program supports.
    # Run program with --help to get a list of available options and with
    # --print-defaults to see which it would actually understand and use.
    #
    # For explanations see
    # http://dev.mysql.com/doc/mysql/en/server-system-variables.html
    # This will be passed to all mysql clients
    # It has been reported that passwords should be enclosed with ticks/quotes
    # especially if they contain "#" chars...
    # Remember to edit /etc/mysql/debian.cnf when changing the socket location.
