3.1
This topic contains information useful to know and understand when using RPMs for installation and upgrading.
Adaptive Computing provides RPMs to install or upgrade the various component servers (such as Moab Server, MWS Server, Torque Server). The Moab HPC Suite RPM bundle contains all the RPMs for the Moab HPC Suite components and modules. However, not every component may be installed or upgraded on the same host (for example, it is recommended that you install the Torque Server on a different host from the Moab Server.

3.1.1 RPM Installation and Upgrade Methods
Depending on your configuration, you may install many servers on a single host, or a single server on its own host. In addition, you can install various clients and GUIs on the same host you installed the server or on another host. For example, you have the Moab Server and the MWS Server on the same host (required) and you install the Torque Server on a different host (recommended).
Be aware that the same host may be called by different names. For example, even though the Moab Server and the MWS Server are installed on the same host, the MWS instructions will call it the MWS Server Host, not the Moab Server Host.
Adaptive Computing provides two different types of RPM installation or upgrade methods.
- The typical method is the original RPM method in which you download the Moab HPC Suite RPM bundle to each host in your Moab HPC Suite environment.
- The offline method is available for configurations where the hosts in your Moab HPC Suite environment do not have internet access in order to download the Moab HPC Suite RPM dependencies. This method requires an authorized user to download the Moab HPC Suite RPM bundle and other related dependencies and create a moab-offline tarball. That tarball is then copied (using scp, DVD, USB drive, or similar) to each host in your Moab HPC Suite environment. See 3.5 Creating the moab-offline Tarball for instructions on how to create the tarball.
Be aware of the following:
-
On RHEL systems, you must be registered for a Red Hat subscription in order to have access to required rpm package dependencies.
-
Because many system-level files and directories are accessed during the installation, the instructions in this guide should be executed with root privileges. You will see that the instructions execute commands as the root user. Also be aware that the same commands will work for a non-root user with the sudo command.
- If using the offline method, the internet-enabled host must have the exact same OS as the hosts within your Moab HPC Suite environment. As the Moab HPC Suite can have several hosts, and each host may not use the same OS, you may need to repeat this procedure for each OS used.
3.1.3 Installation and Upgrade Process
Each host (physical machine) will need to have the Moab HPC Suite RPM bundle and the Adaptive Computing repository enabled. This is referred to as preparing the host. Again this can be done using the typical or the offline method.
Once each host has been prepared, you can install or upgrade the individual components on the designated hosts.
