h2. Details about the Question

Is it possible to install caArray with the grid service on a separate host?

h2. Answer

The caGrid team and the caArray team ran through the command line installation on Linux and prepared the following document with detailed steps:

*Special Notes about this document:*
# The caArray installer will not run if you are connected as the root user, but that's not documented.
# caArray install requires a caArray database to be created before the installer executes. The document has provided instructions for those new to mySQL.
# Code is provided for creating Ant targets for installing caArray components separately.
# A hardcoded "localhost" value in caarray/bda-utils/resource/template-binding.xml was causing problems. Instructions are provided to fix this issue.
# Information about server ports is provided to allow firewall configuration.
# Instructions are provided for testing the configuration using sample data.
