# Plex Media Server Updater PowerShell Module
Windows PowerShell module for automating Plex Media Server updates when running with Cjmurph's Plex Media Server Service Wrapper. This module automates checking for the latest Plex Media Server public or beta channel (PlexPass) versions, checking if the server is "in-use", downloading the update, stopping services/processes, installing the update, and restarting services. Supports interactive or silent execution (for automation), with logging, and notifications. Authentication is performed against Plex.tv server using either Plex Authentication Tokens (User or Server) or Plex.tv credentials.
### Prerequisites
  Supported Operating Systems with supported PowerShell version.
  * Windows 7/Windows Server 2008 with PowerShell 4.0 or later
  * Windows 8/10/11/Windows Server 2012/2016/2019/2022 with PowerShell 5.0 or later
 
  Plex Media Server (https://www.plex.tv/downloads/)
  * 1.7 or later (windows-x86)
  * 1.29 or later (windows-x86_64)

Cjmurph's [Plex Media Server Service Wrapper](https://github.com/cjmurph/PmsService)
  * 1.0.3 or later for PMS windows-x86 builds
  * 1.2.1 or later for PMS windows-x86_64 builds
### Installation
1. Save the module file (Update-PlexMediaServer.psm1) to a folder of the same name in one of your PowerShell module directories  (%ProgramFiles%\WindowsPowerShell\Modules\Update-PlexMediaServer or %UserProfile%\Documents\WindowsPowerShell\Modules by default). See [Installing a Powershell Module](https://msdn.microsoft.com/en-us/library/dd878350).
Or using git, execute the following commands:
```
cd %ProgramFiles%\WindowsPowerShell\Modules\

git clone https://github.com/m1lkman/Update-PlexMediaServer.git
```
2. Import the module by launching PowerShell as an Administrator and running the following command:
```
Import-Module Update-PlexMediaServer
```
(This module is not signed, so you need to change the PowerShell execution policy to unrestricted.)
### Parameters
All parameters can be specified either at the command-line or set in the Parameters section of script file itself if you prefer. Edit at your own risk. See examples below for use cases. Use Get-Help cmdlet for details about parameters and usage.
```
Get-Help Update-PlexMediaServer
```

Update-PlexMediaServer [-PlexLogin] <string> [[-PlexPassword] <string>] [-Plex2FA] [-DisablePlexPass] [-PlexServerPort <int>] [-UserName <string>] [-LogFile <string>] [-Force] [-UpdateCleanup <int>] [-Passive] [-Quiet] [-Build] [-Hostname] [-ReportOnly] [<CommonParameters>]

```
### Examples
For local interactive default execution using Plex Server Online token (requires Plex Server is logged in and claimed) to authenticate to Plex.tv for updates (will honor Plex Server Update Channel Setting):
```
Update-PlexMediaServer
```
or remote execution type either:
```
Invoke-Command -ComputerName Server1 [-Credential] <pscredential> -ScriptBlock {Update-PlexMediaServer}
```
or if Plex Media Server is running in a user context other than the credentials of PowerShell use -Username parameter:
```
Invoke-Command -ComputerName Server1 [-Credential] <pscredential> -ScriptBlock {Update-PlexMediaServer -UserName <UserName>}
```
For local interactive execution with password prompt
```
Update-PlexMediaServer -PlexLogin '<PlexLogin/PlexID>'
```
Execute silently using Plex Authentication Token (Use Get-PlexToken to find your token):
```
Update-PlexMediaServer -PlexToken <Token> -Quiet
```
Execute passively using Plex Server Online Authentication Token (requires Plex Server is logged in and Clamied).
```
Update-PlexMediaServer -UseServerToken -Passive
```
or silently check for beta channel (PlexPass) updates using Plex.tv login and password:
```
Update-PlexMediaServer -PlexLogin <Email/ID> -PlexPassword <Password> -Quiet
```
to disable beta channel (PlexPass) updates and cleanup all Updates from the Updates folder except the latest 2:
```
Update-PlexMediaServer -DisablePlexPass -UpdateCleanup 2
```
force checking for build windows-x86_64 even if windows-x86 build is installed, i.g. upgrade to 64-bit
```
Update-PlexMediaServer -Build 'windows-x86_64'
```
check plex running on localhost and bypass public IP reverse DNS lookup
```
Update-PlexMediaServer -PlexServerHostname 'localhost'
```
To enable email notifications:
```
Update-PlexMediaServer -EmailNotify -SmtpTo Someone@gmail.com -SmtpFrom Someone@gmail.com -SmtpUser Username -SmtpPassword Password -SmtpServer smtp.server.com
```
or enable email notifications with custom SMTP port and SSL authentication:
```
Update-PlexMediaServer -EmailNotify -SmtpTo Someone@gmail.com -SmtpFrom Someone@gmail.com -SmtpUser Username -SmtpPassword Password -SmtpServer smtp.server.com -SmtpPort Port -EnableSSL
```
#Slack channel notification:
```
Update-PlexMediaPlayer -SlackNotify -SlackChannel '#ChannelName' -SlackToken <Slack OAuth Token>
```
### Scheduled Task Example (putting it all together)
Here's the solution I use on my Plex server. I use Windows Task Scheduler to run every night at 2:00am to minimize impact to my family and friends. I use the default execution menthod leveraging my server's Online Authentication Token to install the latest beta channel (PlexPass) updates. I also enabled email notification with log included and update cleanup to remove all previous updates except the latest 2.

In Task Scheduler click on Create Task. Be sure to enable "Run whether user is logged on or not" and check "Run with highest privileges".

Configure a new trigger to occur at a time and frequency when it's most likely that none of your users will be using the Plex Server. I use the following options for this example:

When setting up the action use the below to fill in the dialogs.

Program/script
```
powershell.exe
```
Add arguments
```
-Command "{& Update-PlexMediaServer -Quiet -EmailNotify -IncludeLog -SmtpTo Someone@gmail.com -SmtpFrom Someone@gmail.com -SmtpUser Username -SmtpPassword Password -SmtpServer smtp.server.com -SmtpPort Port -EnableSSL -UpdateCleanup 2}
```

### Find Your Plex Authentication Token (Get-PlexToken)
Get Plex Authentication token so you don't have to save your credentials in your scripts or scheduled tasks (will prompt if either value is missing when running interactively):

Note: [Plex Two Factor Authentication](https://support.plex.tv/articles/two-factor-authentication/) must be disabled (i.e. temporarily) 
```
Get-PlexToken -PlexLogin <Email/ID> -Password <Password>
```
Get-PlexToken Syntax
```
Get-PlexToken [[-PlexLogin] <string>] [[-PlexPassword] <string>] [-PassThru] [-Credential <pscredential>]  [<CommonParameters>]
```
### Q&A

* Q: How do you check the current PowerShell execution policy?
