The first time you launch the Supervisor, you should initialize the cluster. To do this:

1. Select the Server's IP address from the list and click NEXT.
   

2. Add the required Servers to the cluster. To do this, enter the IP address and click LINK.
   

   All Cluster Servers must be accessible to each other. All Servers must be hosted on computers with the same architecture (x86, x64).

   
   

   The first three Servers added become the master Servers. The operation of the cluster is coordinated by its master Servers, which, in particular, take decisions to migrate nodes from one Server to another. You can have 3 or 5 master Servers in the cluster. If only two Servers are added, they can be configured as 1+1 (primary + backup Server).

   
   

3. If required, you can add a user with administrator rights. After the cluster is created, only this user will have access to the supervisor. Please follow the steps below:

   1. Click the Add button.
      

   2. Enter access credentials and click the NEXT button.

4. After you added all Servers, click the INITIALIZE button.

   
   
   

This will initialize the cluster based on the selected Servers. To add more Servers to the cluster, do the following:

1. On the HOSTS tab, click .
2. Enter the IP address of the Server.
   

3. If the Server you are adding is master, select the Manager checkbox.

4. Click ADD HOST.
5. Add all required Servers.
