Ensure that your IBM Cloud Orchestrator Server environment
meet the software prerequisites for your IBM® Cloud
Orchestrator installation.
IBM Cloud
Orchestrator is
installed on the IBM Cloud Orchestrator Server.
The operating system of the IBM Cloud Orchestrator Server must
be Red Hat Enterprise Linux 7.0
or 7.1. The architecture must be x86_64.
The
IBM Cloud
Orchestrator installer
must access one of the following
Red Hat Enterprise Linux repositories:
- Registered Red Hat Network
- Customer-provided yum repository
- Red Hat Enterprise Linux ISO
You must configure the
IBM Cloud Orchestrator Server as
follows:
- The operating system must be installed with at least the standard
minimal installation package.
When installing the Red Hat Enterprise
Linux operating system for the IBM Cloud Orchestrator Server,
the minimal installation package is sufficient, because the IBM Cloud
Orchestrator deployment script
installs the required packages from the corresponding YUM repository
or Red Hat ISO files.
- Host name resolution must work between the IBM Cloud Orchestrator Server and
the OpenStack servers.
You can configure the IBM Cloud Orchestrator Server with
the corporate DNS. If no corporate DNS is available, you must update
the /etc/hosts file on each of the required
servers (for example, IBM Cloud Orchestrator Server, OpenStack Controllers,
compute nodes) to include all of the IBM Cloud
Orchestrator and OpenStack server
hosts. Each entry in the /etc/hosts file must
specify both the fully qualified domain name and the host name, in
that order. To verify that you configured the /etc/hosts file
correctly, run the following commands:
- host <IP_address>
- This command must return the FQDN of the server (for example, ico_server.subdomain.example.com).
- hostname --fqdn
- This command must return the same FQDN as in the previous command.
- hostname
- This command must return the first part of the FQDN that is the
host name (for example, ico_server).
- The ports that are used by IBM Cloud
Orchestrator must be open,
not blocked. For a list of the ports that must be open, see Ports used by IBM Cloud Orchestrator.
- [VMware only] If you install IBM Cloud
Orchestrator on a VMware
virtual machine, install VMware Tools to improve the performance of
the virtual machine.
