The StratusLab administrator command line client will help define parameters and perform the installation.
The first step is to install the StratusLab system administrator command line client from the StratusLab repository on the Front End:
$ yum install -y stratuslab-cli-sysadmin
This will install the system administrator client and all of the necessary dependencies. You can verify that it is correctly installed by doing the following:
$ stratus-config --help Usage: stratus-config [options] [key [value]] If the [value] is not provided, the command returns the current value of the key. ...
The command stratus-config will help you view and set the various parameters for the StratusLab installation. This is essentially an interface to the configuration file /etc/stratuslab/stratuslab.cfg and the associated reference file /etc/stratuslab/stratuslab.cfg.ref.
To list all of the defined parameters (keys) and their values use the command:
$ stratus-config --keys ...
This will display a long list of keys, their current values, and their default values, by section. You can view a single parameter by naming the parameter:
$ stratus-config frontend_system
and set it by giving a value:
$ stratus-config frontend_system centos
Each service has a parameter to determine whether the service will be installed. For example, the registration service:
$ stratus-config registration False
is not installed by default. The values that should be set will be discussed in the following sections.
Once all of the service configuration parameters have been set, you
can use the
stratus-install command to perform the installation.
This command should always be executed on the Front End. It will use
SSH to access the machines (including the Front End!) where the
services will be installed.
Normally, if errors occur in the installation, you can simply correct
the configuration and rerun
This command is designed to simplify the initial installation of the cloud. It can be used also to update the cloud software, although there are some significant limitations when doing this. Notably there are certain parts of the configuration (like the address ranges) that cannot be updated automatically.
