In this recipe, we will learn how to stop and start a single server that belongs to a server group using the CLI. Because servers that belong to a server group might be spread over a series of different machines, with different resources available, you might need to stop a single server, without stopping the entire server group to add more resources and start it up back again. Fortunately, WildFly provides such granularity with regards to stop servers.
For this recipe, both the domain controller and host controllers should be up and running. For their configuration, refer to the recipe Connecting the host controller to the domain controller in this chapter.
