此項建議無法自動檢查。當您傳入 --include-manual 時，掃描結果會列出此項目並附帶這些說明。

Run systemctl list-unit-files --type=service --state=enabled and ss -tlnp on every TDSQL host. Only TDSQL components (mysqld, oss_server, scheduler, zookeeper, gateway/proxy, agents) and required OS services may be enabled or listening; services such as cups, avahi-daemon, bluetooth or telnet are a finding.

修補方式

修補方法: 操作指南或基礎設施修補檔
