USAGE - Module specific

• Set a specific (cleartext) mysql root password

    class { "mysql":
      root_password => 'mys4cr3',
    }
  

• Set a random password ( saved in /root/.my.cnf )

    class { "mysql":
      root_password => 'auto',          
    }
  

• Create a new grant and database

    mysql::grant { 'db1':
      mysql_privileges => 'ALL',
      mysql_password => 'pwd',
      mysql_db => 'db1',
      mysql_user => 'db1',
      mysql_host => 'host',
    }

    class { "mysql": }
  

• Disable mysql service.

    class { "mysql":
      disable => true

    class { "mysql":
      disableboot => true
    }

      version => '1.0.1',
    }
  

• Remove mysql package

      source => [ "puppet:///modules/lab42/mysql/mysql.conf-${hostname}" , "puppet:///modules/lab42/mysql/mysql.conf" ], 
    }
  

• Use custom source directory for the whole configuration dir

    class { "mysql":
      source_dir       => "puppet:///modules/lab42/mysql/conf/",
      source_dir_purge => false, # Set to true to purge any existing file not present in $source_dir
