This Guide covers the installation, configuration, and maintenance of gCore.
Contents
Prerequisites
The following software is a prerequisite for the installation of gCore:
- A platform compatible or made compatible with GT requirements.
- J2SE 1.5.08 SDK or greater. Sun's reference implementation is recommended, but versions from IBM, HP, or BEA should work equally well.
- Ant 1.6.5+ to build gCF sources or to develop services with it.
- a SVN client to install gCore from the SVN repository.
- GNU tar to install gCore from archived distributions.
- sudo to execute shell commands with controlled super-user privileges.
Running gCore in a secure infrastructure raises further prerequisites:
- A ntp server to synchronise your clock with other machines' for correct credential validation.
- [coming soon]
Finally, at least static IP address (if not a DNS name) is needed for all but the simplest testing scenarios.
Installation
gCore may be installed from a SVN repository, or else from pre-packaged archives.
In the first case, installing gCore is tantamount to downloading it into a directory of choice, the gCore location. In the second case, installing gCore is simply matter of expanding the downloaded archive into the the gCore location. In either case, proceed to the installation as a a non-privileged user with read and write permissions for the gCore location.
At the end of the process, the gCore location should contain the following structure:
|-bin | |-config | |-endorsed | |-etc | |-lib | |-libexec | |-share
Some folders are of immediate interest to administrators and developers alike:
bin | executables |
config | gHN configuration files |
etc | container and deployed service configuration files |
lib | standard and deployed service libraries |
share | build tools, standard and deployed service interfaces/schemas |
Configuration
Configuring the installation can be roughly distributed across the following steps: configuring the environment, the container, the gHN associated with a running instance of the container, and the operation of the gHN in a secure infrastructure.
Configuring the Environment
Define an environment variable GLOBUS_LOCATION and point it to the installation directory. Assuming a bash shell:
export GLOBUS_LOCATION = ...absolute path to your gCore location...
Adding $GLOBUS_LOCATION/bin to your PATH environment variable is also highly recommended:
export PATH = $PATH:$GLOBUS_LOCATION/bin
Finally, build gCF form sources requires to set an environment variable BUILD_LOCATION to the location from which ant will be invoked and where temporary build structures and artefacts will be located:
export BUILD_LOCATION = ...absolute path to your build location...
Configuring the Container
Specify the hostname of your machine as the value of logicalHost parameter in the container's configuration file $GLOBUS_LOCATION/etc/globus_wsrf_core/server-config.wsdd:
<parameter name="logicalHost" value="..yourhostname..."/>
Configuring the gHN
In the gHN's configuration file $GLOBUS_LOCATION/config/GHNConfig.xml, override wherever appropriate the default values of the following properties:
securityenabled | true if the gHN can operate in a secure infrastructure, false otherwise. |
mode | in a development' mode, the gHN does not publish its own profile as well as those of the deployed Running Instances in the infrastructure. In a production mode, it does. |
rootVO | the rootVO of the gHN. |
defaultVO | the defaultVO of the gHN. |
infrastructure | the infrastructure of the gHN. |
labels | [coming soon] |
rootGHN | [coming soon] |
GHNtype | [coming soon] |
localProxy | [coming soon] |
coordinates | A pair of comma-separated values for the latitude and longitude of the gHN. Coordinates for some popular locations are available here. |
country | [coming soon] |
location | [coming soon] |
