⬇️Installation

Installation instructions for PowerShell Universal.

MSI Install (Windows)

The MSI install creates a PowerShell Universal service. By default, PowerShell Universal listens on port 5000. You can navigate to http://localhost:5000

MSI downloads are available on our download page.

System installs run as a Windows service. User installs run when the user logs in to the machine. The user install runs in the user's context.

ZIP Install

You can also download the ZIP from our Downloads page if you would like to xcopy deploy the files on Windows or Linux.

Windows

You can start Universal by unzipping the contents, unblocking the files and then executing Universal.Server.exe.

Expand-Archive -Path .\Universal.zip -DestinationPath .\Universal
Get-ChildItem .\Universal -Recurse | Unblock-File
Start-Process .\Universal\Universal.Server.exe

Linux

You can use the following command line on Linux to install and start PowerShell Universal:

 wget https://imsreleases.blob.core.windows.net/universal/production/5.5.2/Universal.linux-x64.5.2.1.zip
 sudo apt install unzip 
 unzip Universal.linux-x64.5.5.2.zip -d PSU
 chmod +x ./PSU/Universal.Server
 ./PSU/Universal.Server

Linux Service

You can use systemd to start PowerShell Universal as a service. The below script is an example of downloading a version of PowerShell Universal and installing it as a service:

# ----
# This script will install PowerShell Universal on Linux as a service
# This has been tested on Ubuntu 20.04 (ARM64) on a Raspberry Pi 4
# ----
# Dependencies:
# wget
# unzip
#
# Make sure they are installed
# ----

# These are used to derive the download URL
PSU_VERSION="5.5.2" # Change this to the current version
PSU_ARCH="arm64" # Change this to your desired architecture
PSU_FILE="Universal.linux-${PSU_ARCH}.${PSU_VERSION}.zip"
PSU_URL="https://imsreleases.blob.core.windows.net/universal/production/${PSU_VERSION}/${PSU_FILE}"

# These are used for installing PowerShell Universal
# If you'd like to use a different path, change this
PSU_PATH="/opt/psuniversal"
PSU_EXEC="${PSU_PATH}/Universal.Server"

# These are for installing it as a service
PSU_SERVICE="psuniversal"
PSU_USER="psuniversal"

sudo mkdir $PSU_PATH
sudo setfacl -m "u:${USER}:rwx" $PSU_PATH

echo "Creating user $PSU_USER and making it the owner of $PSU_PATH"
sudo useradd $PSU_USER -m
sudo chown $PSU_USER -R $PSU_PATH

# If you don't use UFW, you can comment this out
echo "Allow port 5000/tcp"
sudo ufw allow 5000/tcp

PowerShell Module

You can use the PowerShell Universal PowerShell module to install the Universal server. To install the module, use Install-Module.

Install-Module Universal

To install the Universal server, you can use Install-PSUServer.

Install-PSUServer -LatestVersion

Running this command on Windows creates and starts a Windows service on your machine. Running this command on Linux creates and starts a systemd service on your machine. Running this command on Mac OS downloads and extracts the PowerShell Universal server.

Docker

See the Docker page.

IIS Install

Please visit the IIS hosting documentation for information on how to configure PowerShell Universal as an IIS website.

Antivirus Configuration

PowerShell Universal takes full advantage of PowerShell and the PowerShell SDK. It includes PowerShell scripts directly in the product. Consider configuring antivirus to allow execution of PowerShell scripts in PowerShell Universal.

Directories

The following directories contain examples from a standard Windows system of scripts and executable files that you may need to exclude from antivirus checks. Changing paths within appsettings.json or within the installer requires changing which directories are excluded.

Path	Description
%ProgramData%\PowerShellUniversal	Contains log files and appsettings.json
%ProgramData%\UniversalAutomation	Contains PowerShell scripts and artifacts. Contains the single file database when not using SQL integration.
%ProgramFiles(x86)\Universal	Contains PowerShell Universal application executables, libraries and modules.

Executables

It may be necessary to exclude certain executables that run PowerShell scripts. The below is a list of executables that run PowerShell from PowerShell Universal.

Name	Description
Universal.Server.exe	The PowerShell Universal core service.
PowerShellUniversal.Host.exe	The PowerShell Universal host environment executable.
pwsh.exe	PowerShell 7.x
PowerShell.exe	PowerShell 5.x

Default Admin Name and Password

You can use the $ENV:PSUDefaultAdminName and $ENV:PSUDefaultAdminPassword environment variables to change this behavior. These values are only used if no administrator account already exists. This is useful for cloud-based installations.

Agent

The PowerShell Universal Agent executes Event Hub actions. Install it depending on your environment:

Windows (MSI)

The PowerShell Universal Agent MSI is on our download page. After installing the MSI, a PowerShell Universal Agent service runs on your machine. Configure it to connect to PowerShell Universal.

ZIP

ZIP files for each platform we support are on our downloads page. Each ZIP contains a PowerShellUniversal.Agent.exe or PowerShellUniversal.Agent file that can start an agent. Run the process as a service for it to start whenever the machine reboots.

Next Steps

At this point, Universal is up and running. Visit http://localhost:5000 or your default port to navigate to the admin console. Log in with the default admin name and password or create a default admin account.
