Ensure Temporary System Account Passwords Are Cleaned Up

보통레벨 1자동tdsql

설명

TDSQL creates temporary system accounts during certain management operations (such as privilege migration and DCN synchronization). After the operation completes, temporary accounts should be cleaned up. 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).
