There are three installation modes: graphical, command-line, and silent. These modes enable you to choose the interactive or non-interactive option that best suits your needs.
This section provides a brief overview of the installation modes. For installation instructions, see Chapter 2, Installing the Web Server. Graphical, command-line, and silent modes are also available for uninstallation. For uninstallation instructions, see Chapter 4, Uninstalling the Web Server.
The graphical mode is an interactive graphical wizard that walks you through the installation process with a series of screens, prompting for installation information and preferences. This is the default mode when the installation program is started without options (./setup). For more information, see Installing in Graphical Mode.
On UNIX systems, the installation interface defaults to command-line mode if the DISPLAY environment variable has not been exported to your local machine and if X Windows is not supported.
The command-line mode is an interactive, text-based interface that prompts for responses in a terminal window. To activate the command-line mode, start the installation program using the --console option (./setup --console). For more information, see Installing in Command-Line Mode on UNIX and Linux.
Silent installation is a non-interactive mode that enables you to run the installer on multiple hosts using an installer configuration file called a state file. The state file is created when the --savestate option is used with the setup command. The state file is saved in the installation directory, install-dir. The default name of the file is statefile, but the file name can be changed if desired.
To activate the silent mode, create the state file and then start the installation program using the --silent option (./setup --silent state_file). After the silent mode is activated, installation takes place without additional input. For more information about creating a state file and installing the Web Server using silent installation, see Installing in Silent Mode.
