Ensure `secure_file_priv` Is Correctly Configured

SedangLevel 1Otomatistdsql

Deskripsi

secure_file_priv restricts the directory for file operations by LOAD DATA INFILE, SELECT ... INTO OUTFILE, and the LOAD_FILE() function. If unset or empty, MySQL can access arbitrary paths on the filesystem. 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). Passes when secure_file_priv names a specific directory or is NULL (import/export disabled); an empty string fails.

sql_query

out=$(mysql ${TDSQL_MYSQL_OPTS:-} -NBe "SELECT CASE WHEN @@global.secure_file_priv IS NULL THEN 'compliant' WHEN @@global.secure_file_priv = '' THEN 'empty' ELSE 'compliant' END" 2>/dev/null) || exit 1; printf '%s\n' "$out"

Output yang diharapkan: compliant
