Using silent mode to install BMC Server Automation components

You can perform an unattended (silent) installation of the Application Server and other components on a Linux or UNIX system.

You can install all of the following components or a subset.

• Application Server
• RSCD agent
• Network Shell
• PXE server
• TFTP server

To use silent mode for an installation, you create a file of variables that control the behavior of a silent installation on Linux or UNIX. Then, you run the Application Server installation program.

To install the Application Server in silent mode

1. Using any server, create a text file named nsh-install-defaults in the /tmp directory. The file must belong to root.

2. In the file, create an entry for each variable you want to set. Then for each variable you enter in the file, create another entry to export the variable. For example:
   COMPONENT_CHECKED=23
   export COMPONENT_CHECKED
   NSH_INSTALL_SKEL=1
   export NSH_INSTALL_SKEL 

   Warning

   Note

   Ensure that the file is in UNIX format (a format in which a line feed, not a carriage return, specifies the end of a line). Otherwise, installation fails.

   The following table describes how to set each possible variable:The [confluence_table-plus] macro is a standalone macro and it cannot be used inline.
   

3. Save /tmp/nsh-install-defaults.
4. To run the silent installation, enter the following command:
   sh <BBSAversion-platform.sh> -silent
    For example:
   sh BBSA82-SOL10-SPARC.sh -silent
   
   No database connection options are set with this silent installation; you must configure the database as a separate operation after installation.
   
   The nsh-install-defaults file is read only during a silent installation or no TTY installation. You cannot use this file for an installation using console mode.
