When you install Scylla Manager, it installs a local instance of Scylla to use as it’s database. You are not required to use the local instance and can use Scylla Manager with a remote database.
Scylla cluster to be used as Scylla Manager data store.
scylla-manager package is a meta package that pulls both Scylla and Scylla Manager packages.
If you do not intend to use the local Scylla instance you may remove it.
sudo yum remove scylla-enterprise -y
Remove related packages. This would also remove the Scylla Manager.
sudo yum autoremove -y
Install the Scylla Manager client and server packages.
sudo yum install scylla-manager-client scylla-manager-server -y

Note that this would use a simple replication strategy (SimpleStrategy).
If you want to use a different replication strategy, create
