You can customize and use the following sample script to install Horizon Agent on multiple Linux virtual machines (VMs). This script uses SSH to run commands on the Linux VMs.
Before you run the script, make sure that Horizon Agent is not already installed on the VMs.
To copy and paste the script content without page breaks, use the HTML version of this topic, available from the Horizon 7 documentation page at https://www.vmware.com/support/pubs/view_pubs.html.
Script Input
This script reads one input file, which is described in Input File for the Sample PowerCLI Scripts to Deploy Linux Desktops. This script also interactively asks for the following information:
Acceptance of Horizon Agent EULA (end user license agreement)
IP address of the vCenter Server
Administrator login name for the vCenter Server
Administrator password for the vCenter Server
User login name for the Linux VM
User password for the Linux VM
Horizon Agent tar ball path
IP address of View Connection Server
Administrator login name for View Connection Server
Administrator password for View Connection Server
Domain name of the View Connection Server administrator
The AD server's address if Kerberos is the authentication method for Horizon Agent to register the Linux machine with View Connection Server.
Script Content
<#
Install Linux Agent via SSH
The Tool is to upload the Linux Agent installer tar ball to destination VMs and do the installation.
