Ensure No Anonymous Accounts Exist

高级别 1自动化tdsql

说明

Anonymous accounts (with an empty username '') allow any user to log in to the database without specifying a username. Runs the mysql client against the TDSQL data node selected by TDSQL_MYSQL_OPTS (e.g. "-h10.0.0.5 -P4001 -utdsql_audit"); keep the password in ~/.my.cnf or a login path rather than MYSQL_PWD or the command line (see 1.4 and 1.5).
