Ensure the log file permissions are set correctly

中レベル 1自動yugabytedb

説明

The log_file_mode setting determines the file permissions for log files when logging_collector is enabled. The parameter value is expected to be a numeric mode specification in the form accepted by the chmod and umask system calls. (To use the customary octal format, the number must start with a 0) The permissions should be set to allow only the necessary access to authorized personnel. Runs ysqlsh (add the YugabyteDB bin directory to PATH) against PGHOST/PGPORT (default 127.0.0.1:5433) as PGUSER (default yugabyte); supply the password through PGPASSWORD or ~/.pgpass. Passes when log_file_mode grants no access to other users (default 0600; 0640/0660 only if your policy allows group access).

チェック方法

監査方法: SQL クエリ

sql_query

out=$(ysqlsh -h "${PGHOST:-127.0.0.1}" -p "${PGPORT:-5433}" -U "${PGUSER:-yugabyte}" -d "${PGDATABASE:-yugabyte}" -tAc "SELECT CASE WHEN right(current_setting('log_file_mode'), 1) = '0' THEN 'compliant' ELSE 'mode ' || current_setting('log_file_mode') END" 2>/dev/null) || exit 1; printf '%s\n' "$out"

期待される出力: compliant

修正方法

修正方法: ガイダンスまたは IaC パッチ

Set it with the YB-TServer GFlag --ysql_pg_conf_csv="log_file_mode='0600'" on every YB-TServer and restart it.
