Ensure the Replication User Has Minimal Privileges

높음레벨 1자동tdsql

설명

The replication-dedicated account (tdsqlsys_repl) should hold only the minimum privileges necessary for replication. 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). Counts grant lines for 'tdsqlsys_repl'@'%' that contain anything other than REPLICATION SLAVE / REPLICATION CLIENT (or USAGE) on *.*.
