Each server root directory shown in Figure 4-5 has its own Administration Server
and Netscape Console and access to a configuration directory. Each CMS instance
has a corresponding instance of Directory Server that functions as the internal
database for that CMS instance. Each server root directory can have one or more
instances of Certificate Management System, each with its own set of one or two
subsystems and its own corresponding internal database.
Figure 3-1 on page 110 illustrates the ports used by a single CMS instance. You can
also install multiple instances on a single machine, either in the same server root or
as completely separate installations in separate server roots.
When you install additional CMS instances on a machine with a single IP address,
you are required to specify a different set of ports for each CMS instance to listen
on. That is, each CMS instance will require at least four unique ports:
• Internal database port for communication with internal database
• SSL administration port for communication with Netscape Console
• SSL agent port for communication with designated agents
• At least one of these ports:
❍
SSL user port for communication with end entities
❍
Non-SSL user port for communication with end entities
The ports shown above are required for each CMS instance. Each server root needs
two additional unique ports: one for the Directory Server being used as the
configuration directory and one for the Administration Server.
When you install additional CMS instances on a machine that has been set up with
more than one IP address, you can configure each instance to listen to a specific IP
address. If each instance has a different IP address, you can use the same port
numbers for additional CMS instances installed on the same machine—that is, you
can use one set of four or five ports for all the instances.
For more information about installing multiple CMS instances, see Chapter 7,
“Installing and Uninstalling CMS Instances.”
