Info

MCCS 는 설치시 최초 사용자 계정으로 id 가  When you install MCCS, the initial user account ID is set to 'admin' 암호가 and the password is set to 'password'인 계정을 생성합니다.
CLI 명령을 실행시 id 와 password를 입력하지 않으면 , 위의 최초 사용자 계정의 id와 암호로 실행됩니다.
따라서 최초 사용자의 패스워드 변경시, 필수적으로 CLI 명령에 id와 password를 옵션으로 입력해야만 합니다When you run the CLI command, you need to enter the ID and the password. Otherwise, the above initial ID and password will be used.
Thus, when you change the initial user password, you must enter the ID/password in the CLI command as options.

 

Syntax
