Changing to a New Redis (Cache) Server

This section describes how to use the Centrify-PAS-ModifyInstallation.ps1 script to change the Installation to use a new Redis server. For additional Centrify-PAS-ModifyInstallation.ps1 script information, see Centrify-PAS-ModifyInstallation.

To change to a new Redis server:

  1. If you are not already logged in to the Management node, log in as a user with administrator rights.
  2. At an elevated PowerShell prompt, run Centrify-PAS-ModifyInstallation.ps1 using the proper parameters to update the Installation to use a new Redis server. Parameters include:

    • [-RedisServer] <String>]—Enter the Redis server hostname (URI).
    • [-RedisPort] <String>]—Enter the Redis server port, typically 6379.

    For example, to change the Redis server:

    .\Centrify-PAS-ModifyInstallation.ps1 -RedisServer newcache.corpnet -RedisPort 6379

  3. After changing the Installation to use a new Redis server, you must create a new deployment and deploy it to deploy it to all Web and Background nodes. Once you create the new nodes, set the new deployment active. For detailed instructions on deploying new nodes, see the following sections:
