TMA-TDSQL-10.2

Ensure the Replication User Has Minimal Privileges

YüksekDüzey 1Otomatiktdsql

Açıklama

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 *.*.

Nasıl denetlenir

Denetim yöntemi: SQL sorgusu

sql_query

out=$(mysql ${TDSQL_MYSQL_OPTS:-} -NBe "SHOW GRANTS FOR 'tdsqlsys_repl'@'%'" 2>/dev/null) || exit 1; printf '%s\n' "$out" | grep -vcE '^GRANT (USAGE|REPLICATION SLAVE|REPLICATION CLIENT)(, (REPLICATION SLAVE|REPLICATION CLIENT))* ON \*\.\* TO ' || true

Beklenen çıktı: 0

Nasıl düzeltilir

Düzeltme yöntemi: Kılavuz veya altyapı yaması

REVOKE ALL PRIVILEGES ON *.* FROM 'tdsqlsys_repl'@'%'; GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'tdsqlsys_repl'@'%'; (coordinate with the TDSQL Manager, which manages this account).
