在 Horizon Agent 上升級 Linux 桌面平台機器的範例 PowerCLI 指令碼

您可以自訂和使用下列範例指令碼，在多個 Linux 虛擬機器 (VM) 上升級 Horizon Agent。

此指令碼會在安裝 Horizon Agent 之前上傳安裝程式 tar ball 到每個虛擬機器。上傳工作可能很費時，特別是牽涉到大量虛擬機器且網路速度緩慢時。為了節省時間，您可以執行使用 SSH 的指令碼，或將安裝程式 tar ball 放置在每個虛擬機器可使用的共用位置上，以便不需要上傳檔案。

若要複製和貼上不含分頁符號的指令碼內容，請使用本主題的 HTML 版本，您可以從 Horizon7 文件頁面取得，網址是：https://docs.vmware.com/tw/VMware-Horizon-7/index.html。

指令碼輸入

此指令碼會讀取一個輸入檔，在用於部署 Linux 桌面平台的範例 PowerCLI 指令碼輸入檔 中有加以描述。此指令碼也會互動地要求下列資訊：

• 接受 Horizon Agent EULA (使用者授權合約)
• vCenter Server 的 IP 位址
• vCenter Server 的管理員登入名稱
• vCenter Server 的管理員密碼
• ESXi 主機的管理員登入名稱
• ESXi 主機的管理員密碼
• Linux 客體作業系統的使用者登入名稱
• Linux 客體作業系統的使用者密碼
• Horizon Agent tar ball 路徑
• 升級為受管理的虛擬機器
• 安裝智慧卡重新導向功能
