Using silent mode to install an RSCD agent (Linux and UNIX)

You can perform an unattended (silent) installation of the RSCD agent on a Linux or UNIX computer.

To use silent mode for an installation, create a file of installation defaults (variables that control how a silent installation on Linux or UNIX behaves). Then run the RSCD agent installation program.

To install the agent on multiple computers, you can use an Agent Install Job. See the Running the Unified Agent Installer.

To install the RSCD agent 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:
   NSH_INSTALL_SKEL=yes
export NSH_INSTALL_SKEL

   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:

   Variable	Explanation
   INSTALL_DIR	Set this variable to choose an installation directory other than the default installation directory of /opt/bmc/bladelogic.
   COMPONENT_CHECKED	By default, running a silent installation installs all possible components in the installation. To override the default, set the COMPONENT_CHECKED variable. In an RSCD agent only silent installation, the agent is the only possible component for installation. The COMPONENT_CHECKED variable can have only this value: 1 — RSCD agent. When using the file with the Bulk RSCD Agent Installer, set the value to 1 (one).
   IS_SECURE_AGENT_LOGS	Set this variable to 1 to enable secure agent logging. When secure agent logging is enabled for an agent, agent logs are periodically rolled and digitally signed as they are rolled.
   IS_KEYSTROKE_LOGS	Set this variable to 1 to enable keystroke (nexec) logging on an agent. When keystroke logging is enabled on an agent, remote commands run against the agent using nexec are captured and logged in an encrypted manner in keystroke logs. These logs are also periodically rolled and digitally signed as they are rolled.
   INSTALL_BLPRNG	Set this variable to 1 to install the BladeLogic Pseudo Random Number Generator Daemon (PRNGD). BMC Server Automation uses random data to encrypt communication securely. Most systems already have a random number generator device; you may not need this setting. However, if a server on which you are performing a silent installation does not include a hardware device for generating random numbers, the installation program installs the PRNGD.
   NSH_ROOT_HOST	Set this value to identify a client on which users are granted root privileges for this server. This option sets the root= flag in the exports configuration file. By default, no clients are specified.
   NSH_USER_FROM NSH_USER_TO	Set these values to configure a default user mapping in the users.local file. By default, no users are mapped. The values set with this variable create an entry in the users.local file that says: NSH_USER_FROM rw,map=NSH_USER_TO. For example, by defining values for these variables, you could create an entry in users.local similar to the following example: betty rw,map=root. For information about the users.local file, see Users and users.local files overview.
   NSH_INSTALL_SKEL	By default, a silent installation does not include the .nsh/etc/skel files. To install those files, set this variable to 1.
   TMP_DIR	Specifies a location where the installer should uncompress the sysinfo installation file before the file copy.
   STARTUP_AIX	Specifies the type of startup script used for silent installation of the RSCD agent on AIX. You can specify these values: 1 --At system bootup, use the /etc/rc.tcpip file 2 -- Manually (I will do it myself) 3 --At system backup, use the /etc/rc.d/init.d/rscd file

3. Save /tmp/nsh-install-defaults.
4. To run the installer, enter the following command:
   sh <RSCDversion-platform> -silent
   For example:
   sh RSCD82-SOL10-SPARC.sh -silent
