Chapter 3 Installing Server Software 77
Installing Multiple Servers
You can use Server Assistant, VNC viewer software, or the installer tool to initiate
multiple server software installations. After using Server Assistant to initiate server
software installation on one remote computer, choose File > New Window to install the
software on another computer.
After using a VNC viewer to control installation of Mac OS X Server version 10.4.7 or
later on one remote computer, you can use the VNC viewer to open a connection to
another remote computer and control installation on it.
Alternatively, open the Terminal application and use the installer tool to initiate
another server software installation.
