How do I add a new cluster node?

This topic applies to Dynatrace Managed installations only.

To add a new node to your Dynatrace Managed cluster:

Log in to your Dynatrace Managed Cluster Management Console.

From the navigation menu, select Home to go to the Dynatrace Managed deployment status page.

Click Add new cluster node.

Copy the wget command line from the Run this command on the target host text box.

Paste the wget command line into your terminal window.

Run the installer. You need root rights to install Dynatrace Managed Server. You can use su or sudo to run the installation script. To do this, type one of the following commands into the directory where you downloaded the installation script.

Type Accept if you agree to the Dynatrace Managed Terms of use. Installation won't continue until you complete this step. To quit installation, press Ctrl+C.

The Dynatrace Managed installer works in interactive mode. It displays prompts for values like the installation path and user account. You can accept the default values by pressing Enter. To override the settings, type your choices in the terminal and press Enter.

Once installation on the node is complete, click Back to return to your Cluster Management Console home page. You'll soon see that the new node is connected.

You can add a new node by following the same procedure as explained for installation of the first node in your cluster. The only difference is that when you copy the wget command from the email, the installer asks you during installation whether or not you want to add the node to an existing cluster (if so, you have to enter the IP address of an existing cluster node) or if you intend to set up a new cluster. You can alternatively use the --seed-auth parameter to skip this step. In this way, the newly created node will be automatically added to the existing cluster.
