Changing the root password - Adaptive Applications - BlueCat Gateway - 21.3

The root password is left blank during the installation of the nodes in the database node cluster to ensure that the nodes can successfully establish replication between all nodes. Once all nodes have been installed and are replicating, you must change the root password to secure the cluster.

1. Log in to the console of any node in the database node cluster.
2. Open a shell inside the first database node using the following command:

   docker exec -it <node_name> /bin/bash

   This opens a bash command line within the container.

3. Log in to the database 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

Once you have successfully configured the Distributed DDNS Data Nodes, you can proceed to install the Distributed DDNS Application Node and Distributed DDNS Service Nodes.
