Appendix A
Package Management for AWMS
Yum for AWMS
This appendix describes the Yum packaging management system. Dell recommends running Yum to ensure your
packages are up to date, and so that your AWMS is as secure as possible if you are running RHEL 5 or CentOS 5.
Yum is an automated package management system that verifies AWMS is running the
most recently released
RPMs and upgrades any out-of-date packages. Yum accesses the Internet, and downloads and installs new
versions of any installed RPMs. It is important to keep the AWMS RPMs as current as possible to close any
known security holes in the OS as quickly as possible.
To run Yum on a CentOS 5 machine
follow the instructions below:
1. Before running Yum for the first time, you need to install th
e GPG key. The GPG key is used to validate the
authenticity of all packages downloaded by Yum.
2. To install the GPG key, type
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5. If the key was not
manually installed before Yum is run for the first time the user will be prompted to install and accept a new
key.
3. To run Yum manually, log in to the AWMS consol
e and type yum update and press Enter. If the packages seem
to be downloading slowly, press
Ctrl+C to connect to a new mirror.
4. To configure Yum to run nightly, type
yum install yum-cron and press Enter. Then type service yum start and
press
Enter. Note that yum-cron will default to off if the machine is restarted.
5. To configure yum-cron to start at system startup, type
chkconfig yum-cron on and press Enter.
6. In some instances, running Yum may cause a problem with AWMS. If
that happens, a good first step is to use
SSH to go into the AWMS server as root, and issue the following command:
# root; make
If that does not resolve the issue, please contact Dell support for further assistance.
