Install the App Layering Agent

注意

The App Layering Agent is required for Provisioning Services and connector scripts.

The App Layering Agent enables the App Layering appliance, also known as Enterprise Layer Manager (ELM) or the App Layering packaging machine virtual machine to run PowerShell commands locally. If you supply the proper credentials, the agent can run PowerShell commands as a specific user.

The App Layering Agent is required in cases where one of your connector configurations starts a PowerShell script. The script includes connector configurations that you use to do the following.

  • Publish layered images to a provisioning system.
  • Package layers in your hypervisor environment.

The App Layering Agent installer prompts you to register the agent with an App Layering appliance. If you do not register the agent during installation, you can manually register it later. However, remember that the PowerShell scripts do not run until the agent is registered with the ELM.

Prerequisites

Before you install the App Layering Agent, you must have the following requirements on the system where you are installing the App Layering Agent:

  • An account with administrator privileges
  • .NET 4.5
  • PowerShell 3.0 or greater
  • Windows PowerShell snap-in
    Before using the App Layering Agent on a Provisioning Services server, ensure that you installed the PowerShell snap-in.
    • For Provisioning Servers 7.7 and later, you must install the PowerShell snap-in Citrix.PVS.Snapin.dll.
    • For Provisioning Services 7.6 and Provisioning Services 7.1, you must install the McliPSSnapIn.dll. Use the installutil.exe to install the snap-in.

Example (7.6):
At a command prompt, type:

Change directory 复制

cd c:\program files\citrix\provisioning services console

At a command prompt, type this command and then press Enter:

Command 复制

"C:\Windows\Microsoft.NET\Framework64\v4.0.30319\InstallUtil.exe" McliPSSnapIn.dll

Example (7.7):
At the command prompt, type: 

Change directory 复制

cd c:\program files\citrix\provisioning services console

At the command prompt, type this command and then press Enter:

Command 复制

"C:\Windows\Microsoft.NET\Framework64\v4.0.30319\InstallUtil.exe" Citrix.PVS.snapin.dll

On Windows 2008 R2, you must also enable PowerShell remote commands. For background information, see the Microsoft article Enable-PSRemoting.

If your 2008 R2 OS does not have PowerShell remoting enabled, run the following PowerShell command on the Provisioning Services server:

Command 复制

Enable-PSRemoting

If you previously installed the App Layering Agent, you can download updated versions from the Citrix downloads page. The App Layering Agent is a standalone installation package and is also included in the full App Layering software package.

To download the App Layering Agent

  1. Go to the Citrix home page and then click Sign in.
  2. Click Downloads and then select Citrix App Layering in the drop-down list.
  3. On the Citrix App Layering page, under Citrix App Layering 4.4 > Product Software, click Citrix App Layering 4.4.
  4. At the bottom of the page, click Tools.
  5. Under Citrix App Layering 4.4 Agent, click Download File.
    The file citrix_app_layering_agent_installer.exe downloads to your computer.

To install the App Layering Agent

Log on as an administrator to the system where you are installing the agent.

Copy the file citrix_app_layering_agent_installer.exe from your computer to the Provisioning Services server.

Run the installation program as an administrator. When prompted, type the path to the directory where you want to install the App Layering Agent. The default location is C:\\Program Files (x86)\Unidesk\Agent.

The App Layering Agent installer checks to ensure that all the prerequisites are present. If any prerequisites are missing, the installer notifies you and then exits without installing.

The installer prompts you for an Agent Port number. You can accept the default port number (8016). If the default port is in use, you can specify a different port number.

The installer prompts you for the credentials (address, user name, and password) for your App Layering appliance. Type the IP address and logon for an administrator with permission to access the App Layering management console.

注意

If you don't register the App Layering appliance now, you can register the appliance later. For more information, see the procedure Register with the App Layering appliance manually.

Click Finish to exit the wizard.

Register the App Layering Agent manually

If you did not register the App Layering Agent with an App Layering appliance during installation, you can register it manually.

To register the App Layering Agent manually

Log on as an administrator to the server where you installed the App Layering Agent.

Open a command window (cmd.exe) as an administrator. Go to the directory where you installed the App Layering Agent. For example:

Change directory 复制

CD c:\\Program Files (x86)\Unidesk\Agent

Run the following command by using the IP address of the App Layering appliance where indicated:

Command 复制

Unidesk.Agent.Service.exe register /i /e:IP_address_of_ELM /u:Administrator

When prompted, type the password for an administrator with privileges. Ensure that the password is for the App Layering management console.

When registration is done, a message appears that informs you of the successful outcome. The App Layering Agent registration appears in the audit log for the management service.

If the process is not successful, review the log file at \Unidesk\Agent\Logs\unidesk.agent.log file in the App Layering Agent installation directory. You can also view Help for the App Layering Agent command-line options by running the following command:

Command 复制

Unidesk.Agent.Service.exe /?
