Starting Up a Cluster Using the Installer Startup Button
You can use a single button to start software on a cluster.
About this task
The Startup button is a feature of Installer 1.8 or later. The Startup button appears on the status page of the Installer web interface when the cluster is in the shutdown state. The Startup button starts Warden and Zookeeper, which in turn start other running services that are part of a cluster.
NOTE
If the Startup button is not visible and the
Shutdown button is present, the cluster is still running
and is not in the shutdown stateThe Startup button works differently depending on your cluster
deployment:
Deployment | Startup Button Behavior |
---|---|
On premise | Starts the Zookeeper and Warden services on all nodes. |
In the cloud | Starts the virtual machine nodes and then starts Zookeeper and Warden services on all nodes. |
To use the Startup button:
Procedure
- For a cluster deployed in the cloud, use the AWS console or the Azure portal to ensure that the nodes are shut down before you try to start them.
-
Use a browser to connect to the cluster using the Installer URL:
https://<Installer Node hostname/IPaddress>:9443
- On the status screen, click the Startup button. The Installer displays the Authentication screen.
-
Enter your authentication information if requested, and click
Startup. The installer begins the startup
process.
- To shut down software on the cluster, see Shutting Down a Cluster Using the Installer Shutdown Button.
