Configuring the First and Subsequent Hosts
The configuration procedures differ depending on if you run MarkLogic Server in a cluster configuration or on a single host.
If you are configuring MarkLogic Server as a standalone host, or if this is the first host in a cluster configuration, follow the installation instructions in Configuring a Single Host or the First Host in a Cluster. Otherwise, follow the installation instructions in Configuring an Additional Host in a Cluster.
If you are upgrading a cluster to a new release, see Upgrading a Cluster to a New Maintenance Release of MarkLogic Server in the Scalability, Availability and Falover Guide. The Security database and the Schemas database must be on the same host, and that host should be the first host you upgrade when upgrading a cluster.
