Installing Managed System Software on Supported Linux Operating Systems 137
Prerequisites for Installing Managed System Software
• You must be logged in as root .
• The running kernel must have loadable module support enabled.
• The
/opt directory must have at least 250 MB of free space, and the /tmp
and
/var directories must each have at least 20 MB of free space. If you
choose to use a non-default directory for the installation, then that
directory must also have at least 250 MB of free space.
• The
ucd-snmp or net-snmp package that is provided with the operating
system must be installed if you use SNMP to manage your server. If you
want to use supporting agents for the
ucd-snmp or net-snmp agent,
you must install the operating system support for the SNMP standard
before you install Server Administrator. For more information about
installing SNMP, see the installation instructions for the operating system
you are running on your system.
NOTE: When installing an RPM package in Red Hat Enterprise Linux or SUSE
Linux Enterprise Server, to avoid warnings concerning the RPM–GPG key,
import the key with a command similar to the following:
rpm --import /mnt/dvdrom/SYSMGMT/srvadmin/
linux/RPM-GPG-KEY
• Install all the prerequisite RPMs required for successful installation.
If your system came with a factory installed Red Hat Enterprise Linux
(versions 4 and 5) or SUSE Linux Enterprise Server (version 10) operating
system, see the Server Administrator installation readme file
(
readme_ins.txt ) on the Dell Systems Management Tools and
Documentation
DVD for information on any RPMs that you need to
manually install prior to installing managed system software. In most cases
you will not need to manually install any RPMs. See the readme file for
more information.
If your system did not come with a factory installed Linux operating
system, and you did not install a Red Hat Enterprise Linux (versions 4
and 5) or SUSE Linux Enterprise Server (version 10) operating system
using the Dell Systems Build and Update Utility, you need to manually
install the prerequisite RPMs prior to installing managed system software.
For your convenience, these RPM files are provided on the
Dell Systems
Management Tools and Documentation
DVD. Navigate to
