General recommendations:
Remove Anonymous User accounts - there are 2 anonymous accounts.
Set up a Password for user with the following SQL statement ( SET PASSWORD FOR 'user'@'SpecificDNSorIp' = PASSWORD('secure_password'); )
Set up a Secure Password for user@host ( SET PASSWORD FOR 'user'@'SpecificDNSorIp' = PASSWORD('secure_password'); )
Restrict Host for user@% to user@SpecificDNSorIp
MySQL started within last 24 hours - recommendations may be inaccurate
Variables to adjust:
innodb_buffer_pool_size (>= 2G) if possible.
innodb_buffer_pool_instances (=1)
