Ensure Correct Permissions on the Temporary File Directory

中等級 1自動化tdsql

說明

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.
