vsftpd 서비스가 시작되지 않았으며 vsftpd.service 메시지가 표시됩니다: 기본 프로세스가 종료되었습니다. 코드=종료, 상태=2/INVALIDARGUMENT

이 FTP 서버를 실행하기 위해 Ubuntu를 실행하는 가상 머신을 구성하기 위해 Ansible을 사용하고 있지만 vsftpd, 설치 후 로그를 확인하면 다음과 같은 내용 journalctl -u vsftpd.service이 표시됩니다.

제가 설정한 구성에 어떤 문제가 있는지 잘 모르겠습니다. 구성 /etc/vsftpd.conf은 다음과 같습니다.

anonymous_enable=NO        # disable anonymous login
local_enable=YES           # permit local logins
