Installation Overview212 Netscape Certificate Management System Installation and Setup Guide • May 2002You must have an Administration Server in each server root directory.Administration Server can use a local configuration directory or refer to an existingconfiguration directory installed elsewhere. You must install the CertificateManagement System internal database directory locally.The initial installation script installs Netscape Console and the binaries for theservers, and it creates and starts instances of Administration Server and DirectoryServer. After running the initial script, you use the Installation Wizard to createand configure instances of Certificate Management System. The wizard helps youthrough the configuration process of choosing subsystems and creating thenecessary keys and certificates.Installation StagesInstalling Certificate Management System in a single server root directory involvesfour stages:• Stage 1: Run the installation script (setup on UNIX, setup.exe on NT) toinstall Administration Server and Directory Server as necessary and performthe initial phase of CMS installation. These procedures are described in “Stage1. Running the Installation Script” on page 215.• Stage 2: Run the Installation Wizard to set up the initial configuration of theCMS instance. In this stage you specify which subsystems are to be part of thisinstance and generate the SSL client and server certificates for each subsystem.These procedures are described in “Stage 2. Running the Installation Wizard”on page 221.• Stage 3: Use Netscape Console to further configure the new CertificateManagement System instance, as needed. See “Stage 4. Further ConfigurationOptions” on page 277.• Stage 4 (optional): Use Netscape Console to create additional instances of theCertificate Management System in the same server root directory, and use theInstallation Wizard to configure them. For a summary, see “Stage 5. CreatingAdditional Instances or CA Clones” on page 278.
