Installing iPlanet Web Server for Unix
28 Installation and Migration Guide
6. Type a server root directory or accept the default (/usr/netscape/
server4).
This directory is where the server files and directory structure will be
installed.
You need to run the server as a user that has write access to this directory,
for example, the directory owner.
If you have an iPlanet Web Server version 4.0 already installed, and you
want to upgrade it, you must choose the installation directory where your
4.0 server is installed. The installation program automatically upgrades the
server from 4.0 to 4.1.
7. Choose iPlanet Web Server, Enterprise Edition, all components.
Press Enter.
8. Choose the iPlanet Web Server, Enterprise Edition subcomponents to install.
If you do not install a subcomponent and later decide you want to use it,
you can run the installer again to install just the missing subcomponent.
However, you cannot uninstall individual subcomponents once they are
installed.
By default, all subcomponents except WAI support are installed.
If you are upgrading from iPlanet Web Server 4.0, when you install
subcomponents, you must install all the subcomponents you installed for
4.0, otherwise they are not upgraded properly and may not work. You can
install additional subcomponents as well.
The subcomponents you can choose to install are described in the
following numbered sections.
1. Server Core
Installs Administration Server and the first instance of iPlanet Web Server.
Warning You must install the Server Core subcomponent the first time you install
iPlanet Web Server. If you install additional subcomponents later, you are
not required to reinstall the Core subcomponent.
