The SQL database of choice for most real-world purposes (i.e., for your average database needs). Bit finicky on occasion, but I loathe databases (given the choice, I'd probably use Postgres).
Lockdown in a nutshell:
;/etc/my.cnf [mysqld] port=3306 set-variable = key_buffer=8M set-variable = max_allowed_packet=1M set-variable = thread_stack=128K bind-address = 127.0.0.1
DROP DATABASE test; use mysql; DELETE FROM db WHERE Db like 'test%'; DELETE FROM user WHERE Host = '%'; DELETE FROM user WHERE User = ''; UPDATE user SET Password = password('mypassword') WHERE User = 'root'; FLUSH PRIVILEGES;
