Though it is well documented in the SDL doc, I am just consolidating all into one place -

Prerequisite:

• Install JDK 8 or Latest version.
• Download the appropriate version (.net/java) of  DXA 2.0 as per your choice. (Here I am using .Net version)
• Also you need to download the SDL Web Content Delivery layout: CD_10.1.0.8270 (Note: This is not yet released as a part of DXA 2.0, so to get that please raise a request to SDL customer support team. You can directly raise it through SDL Support portal at https://gateway.sdl.com.)

Note: Model service basically used as a microservice for Content Delivery, so SDL recommend to install the Model Service on the same machine where the Content Delivery setup is done.

Installation Procedure:

• Create a new folder in your target machine, and rename it to a unique name as per you choice. Here for example I named it as a model-service
• Copy the below folders from the downloaded installation media

• By default, this microservice runs on the port 8998. If you want to change the port, you can change it in the  cd_storage_conf.xml file, as well as you have to pass the port no as a parameter of the command to the installer. (As a alternative of this  you can also specify the port no. in the installService.ps1 script under the model-service\bin\ folder)
• Now everything is set. So to install the service
  open PowerShell >> Go to the bin folder (for me it is C:\SDL\Web\model-service\bin) >>
  Run the below script.

  PS C:\SDL\Web\model-service\bin> & '.\installService.ps1' --server.port=8998

  if you want to register automatically then add the additional parameter like below -

  & '.\installService.ps1' --register --server.port=8998

  

  Note: You can also change the default values to something meaningful for the Model Service by editing the installService.ps1, such as in the following example:

  $name="SDLDXAModelServices"
  $displayName="SDL DXA Model Services" $description="Content Delivery Micro Services For DXA"

that’s it.
