Installation Overview

You can install a SDK for Perl package on a supported platform or deploy the vMA virtual machine on an ESXi host.

■	SDK for Perl packages. Install a SDK for Perl package on a physical or virtual machine. See Installing the SDK for Perl Package on Red Hat Enterprise Linux, Installing SDK for Perl on Linux Systems with Internet Access, and Installing and Uninstalling SDK for Perl on Windows.

The SDK for Perl installer installs both vSphere SDK for Perl and vCLI because vCLI commands run on top of the vSphere SDK for Perl. The contents of the installer package differs for different platforms.

Platform	Installation Process
Windows	The installation package includes vCLI, vSphere SDK for Perl, and prerequisite Perl modules.
Red Hat Enterprise Linux	You must install required software. See Installing Required Prerequisite Software for Red Hat Enterprise Linux. If you have Internet access, RHEL downloads Perl modules from CPAN. If you do not have Internet access, the installer installs Perl modules that it does not find on your system from the installer package.
SLES and Ubuntu	You must install required software and you must have Internet access. See Installing Required Prerequisite Software for Linux Systems with Internet Access. The installer downloads other Perl modules from CPAN.

After installation, you can run vCLI commands and vSphere SDK for Perl utility applications from the operating system command line. Each time you run a command, you specify the target server connection options directly or indirectly. You can also write scripts and manage your vSphere environment using those scripts.

■	vMA. Deploy vMA, a virtual machine that administrators can use to run scripts that manage vSphere, on an ESXi host. vMA includes vCLI, vSphere SDK for Perl, and other prepackaged software in a Linux environment.

vMA supports noninteractive login. If you establish an ESXi host as a target server, you can run vCLI and vSphere SDK for Perl commands against that server without additional authentication. If you establish a vCenter Server system as a target server, you can run most SDK for Perl commands against all ESXi systems that server manages without additional authentication. See Deploying vMA.
