Bright Cluster Manager® can be kept up to date very easily using simple tools and instructions.
All software included with Bright Cluster Manager is provided in the form of RPM packages. Therefore, the standard RPM tools can be used to keep your Bright cluster up-to-date:
The Red Hat Package Manager (RPM) can be used to manually update, install and remove packages.
The Yum tool (Yellowdog Updater, Modified) is a convenient wrapper around the RPM tool which allows the cluster to be updated using remote software repositories.
Moreover, Yum takes care of resolving RPM package dependencies.
- Zypper is a command line package manager based on the libzypp library. Similar to Yum, it is a convenient wrapper around the RPM tool which allows the cluster to be updated from remote software repositories.
Zypper also takes care of resolving RPM package inter-dependencies.
Bright Cluster Manager's node provisioning system ensures that you only need to keep your head node and the regular node images on your head node up-to-date. The provisioning system will take care of updating your regular nodes.
Yum is automatically preconfigured on your cluster to download packages from the correct packages repository:
- The Bright Computing RPM repository provides all packages that are written or maintained by us.
These packages are usually specific to Bright Cluster Manager.
- The RPM repositories of the Linux distributions used, such as
SUSE Linux Enterprise Server (SLES),
Red Hat Enterprise Linux (RHEL),
provide all packages for that distribution. You may require a license or subscription to access these repositories.
“There is no way in hell I could run a one-man shop like this without Bright Cluster Manager.”
