Installing Managed System Software on Supported Linux Operating Systems 105
Prerequisites for Installing Managed System Software
• You must be logged in as root .
• The running kernel must have loadable module support enabled.
•Your
/opt directory must have at least 250 MB of free space, and your /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/cdrom/srvadmin/linux/RPM-GPG-KEY
• You must install all the prerequisite RPMs required for successful installation.
If your system came with a factory installed Red Hat Enterprise Linux (versions 3 and 4) or SUSE Linux
Enterprise Server (versions 9 and 10) operating system, see the Server Administrator installation
readme file (
readme_ins.txt ) on the Dell PowerEdge Installation and Server Management CD 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 to be sure.
If your system did not come with a factory installed Linux operating system, and you did not install a
Red Hat Enterprise Linux (versions 3 and 4) or SUSE Linux Enterprise Server (version 9 and 10)
operating system using Server Assistant, then you need to manually install the prerequisite RPMs prior
to installing managed system software. For convenience, these RPM files are provided on the
Dell PowerEdge Installation and Server Management CD or package. Navigate to the appropriate
/srvadmin/linux/RPMS/supportRPMS/ operating-system subfolder for your specific Red Hat
Enterprise Linux (versions 3 and 4) or SUSE Linux Enterprise Server (versions 9 and 10) operating
system and run
rpm -Uvh * to install these RPM files before installing managed system software.
Installing Managed System Software Using the Dell PowerEdge Installation and Server Management CD
The Dell PowerEdge Installation and Server Management CD uses RPMs to install each component.
The CD is divided into subdirectories to enable easy Custom Installs.
If you would like to review the software before you install it, follow this procedure:
1
Load the Dell PowerEdge Installation and Server Management CD into your system's CD drive.
2 If necessary, use the command line to mount the CD using a command such as:
mount /dev/cdrom /mnt/cdrom
