Changing the Distributed DDNS root password - Adaptive Applications - BlueCat Gateway - 23.2.4

During installation of nodes in the database cluster, the root password is left blank to make sure that the nodes can successfully establish replication between all nodes. After all nodes are installed and replicating, you must change the root password to secure the cluster.

1. Log in to the console of any node in the database cluster.

2. Open a shell inside the first Data Node using the following command:

   docker exec -it <node_name> /bin/bash

   Doing so opens a bash command line within the container.

3. Log in to the Data Node using the following command:

   mariadb -uroot

4. Change the root password using the following command:

   SET PASSWORD FOR 'root'@'localhost' = PASSWORD('<new_root_password>');
   SET PASSWORD FOR 'root'@'%' = PASSWORD('<new_root_password>');
   FLUSH PRIVILEGES

After you successfully configure the Distributed DDNS Data Nodes, you can install the Distributed DDNS Application Node and Distributed DDNS Service Nodes.
