-------- Recommendations -----------------------------------------------------
General recommendations:
  Add skip-innodb to MySQL configuration to disable InnoDB
  Reduce your overall MySQL memory footprint for system stability
  When making adjustments, make tmp_table_size/max_heap_table_size equal
  Reduce your SELECT DISTINCT queries without LIMIT clauses
Variables to adjust:
  tmp_table_size (> 128M)
  max_heap_table_size (> 64M)

Ah, I needed to run it with a username and password. The root account didn't have a password, so I had to make one. Sorry! Thanks.

This ticket won't close. A little help here...?

I've got it. ;-)

I had the same problem. For posterity, here's the command that worked for me:

$ sudo mysqltuner.pl --user root --pass
