Installations

Use the Server, Web Applications, and Client installations to install the groups of components that make up Cherwell Service Management.

CSM provides the following installations:

Server: Installs the Server Manager, the Cherwell Application Server, and the Cherwell Service Host.
Portal and Browser Applications: (Also called Web Apps) Installs the CSM Browser Client, CSM Portal, Cherwell REST API, and Auto-Deploy.
Client: Installs the main Client applications (client-only files) and administrator tools (optional). (You can optionally install the server files as well, but it is not typical). For most users, the Client applications will be installed via Auto-Deploy.
Run the Server installation first, then the Web Applications installation. Client installations are run last and are typically pushed out to client computers using the Auto-Deploy feature (Auto-Deploy is configured separately to push out a preconfigured Client installation and connection).

The following tables describe the installation components in each installation.
