Vizlib Server Guides - Multi-Node Configuration (Enterprise) - VMC

If you're setting up a Qlik Sense multi-node environment to work with Vizlib Server you need to make configuration changes both the Vizlib Management Console (VMC) and the Qlik Management Console (QMC). This article contains instructions on configuring virtual proxies in the VMC. You can find instructions on the QMC configuration for a multi-node environment here and the Vizlib Server configuration reference here 


TABLE OF CONTENTS


Checklist


Before you start the configuration, make sure you've gone through the items on this checklist, completing each process and collecting each piece of information. 

  • Vizlib Server - You need to have Vizlib Server installed on the target server. You can find instructions on installing Vizlib Server in our article here
  • SSL Certificates - You'll need a separate set of SSL certificates (Figure 1for each node, for an environment with 3 nodes, you should have 3 folders containing their SSL Certificates, each with a unique name. Exported SSL certificates can be found under the path.
/Qlik/Sense/Repository/Exported Certificates/.Local Certificates


Figure 1: SSL Certificates


  • A username and password for the Vizlib Management Console (VMC) or a user account with Root Admin access. Find out more about VMC user roles here
  • Port numbers and host URLs for the QlikSense Proxy Service (QPS) and the QlikSense Repository Server (QRS).

VMC Configuration


Note on Adding QS Nodes: While each new node will have similar settings to the central node there are a couple of important differences. 

  • The URL paths of the certificates should be saved in a separate directory with a unique name. We recommend using the node name, see the example below for a node Rim01
/Qlik/Sense/Repository/Exported Certificates/Rim01_Cert/client_key.pem
  • The domain used for QPS and QRS settings should include the node name. 
Rim01.yourdomain.com
  • Log into the VMC, then navigate to System Settings > Qlik Sense to open the configuration screen. 

  • Enter the configuration for the central node (Figure 2). Select the Certificate Type, then add the paths for each certificate. Tip: Click on the  icon to show instructions on exporting Qlik Sense certificates.

  • Click Restart (upper right corner of the VMC screen) when the information has been added. You will need to restart Vizlib Server after you add a Virtual Proxy to save the updated settings. 

  • Check that a green tick is showing in the Qlik Sense panel on the dashboard (Figure 3), to show the configuration is correct.

  • Repeat the process for each rim node in your environment. Start by Clicking on Add QS Node (Figure 4).


Figure 4: Add QS Node


For each node you configure, should see a green tick on the dashboard.

Next Steps - QMC Configuration


To complete the configuration for a Multi-Node Qlik Sense Environment, you need to configure Virtual Proxies using the Qlik Management Console (QMC). The instructions are in our article here
