Ensure Correct Permissions on the Temporary File Directory

СреднийУровень 1Автоматическаяtdsql

Описание

The MySQL tmpdir may contain temporary tables, intermediate query results, and sort files. Its effective location must be placed on a controlled filesystem and be accessible only to the operating-system account that runs the database. 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). Reads the effective tmpdir from the instance and requires each directory to be owned by a non-root (service) account and not writable by group or other (0700, or 0750 with an approved group). Run on the data-node host; also confirm with findmnt -T that it is on an approved filesystem.

Как проверяется

Метод проверки: SQL-запрос

sql_query

t=$(mysql ${TDSQL_MYSQL_OPTS:-} -NBe "SELECT @@global.tmpdir" 2>/dev/null) || exit 1; bad=0; seen=0; IFS=':'; for d in $t; do seen=1; s=$(stat -Lc '%a %U' "$d" 2>/dev/null) || { bad=1; continue; }; p=${s% *}; o=${s#* }; [ $((0$p & 022)) -eq 0 ] || bad=1; [ "$o" != root ] || bad=1; done; [ $seen -eq 1 ] && [ $bad -eq 0 ] && echo compliant || echo noncompliant

Ожидаемый вывод: compliant

Как исправляется

Метод исправления: Рекомендация или патч инфраструктуры

install -d -m 0700 -o tdsql -g tdsql /data/tdsql_tmp, set tmpdir to it through the TDSQL custom parameter template and restart the instance.
