Linux 데스크톱 시스템에서 Horizon Agent를 업그레이드하기 위한 샘플 PowerCLI 스크립트

다음 샘플 스크립트를 사용자 지정한 후 사용하여 여러 Linux VM(가상 시스템)에서 Horizon Agent를 업그레이드할 수 있습니다.

이 스크립트에서는 Horizon Agent를 설치하기 전에 각 VM에 설치 관리자 tar ball을 업로드합니다. 업로드 작업은 시간이 오래 걸릴 수 있으며, 관련된 VM의 수가 많고 네트워크 속도가 느린 경우에는 특히 더 그렇습니다. 시간을 절약하려는 경우에는 SSH를 사용하는 스크립트를 실행하거나 파일을 업로드할 필요가 없도록 각 VM에서 사용할 수 있는 공유 위치에 설치 관리자 tar ball을 넣을 수 있습니다.

스크립트 입력

이 스크립트는 Linux 데스크톱 배포를 위한 샘플 PowerCLI 스크립트의 입력 파일에 설명된 단일 입력 파일을 읽습니다. 이 스크립트는 또한 다음 정보를 대화형으로 요청합니다.

• Horizon Agent EULA(최종 사용자 라이센스 계약) 수락
• vCenter Server의 IP 주소
• vCenter Server의 관리자 로그인 이름
• vCenter Server의 관리자 암호
• ESXi 호스트의 관리자 로그인 이름
• ESXi 호스트의 관리자 암호
• Linux 게스트 운영 체제의 사용자 로그인 이름
• Linux 게스트 운영 체제의 사용자 암호
• Horizon Agent tar ball 경로
• 관리되는 VM으로 업그레이드
• 스마트 카드 리디렉션 기능 설치
