You can increase the capacity of your server by spreading these tasks across different hosts. The following rules apply:

• The hosts should share a common network file system, and path of the project directory, on any host, should map to the same place. (Exception: the database server can run anywhere).
• The project admin account should exist on all hosts, and that user should be able to use 'ssh' to run commands on any other host without typing a password.
• One host is designated as the project's main host in config.xml. The 'start', 'stop', and 'status' scripts should normally be run on the main host (if you run them on a different host X, they'll affect only daemons and tasks on host X).
• The project admin account on all hosts must be able to access the project's MySQL database. (Exception: data servers and file upload handlers don't need DB access).

• Scheduling servers are listed in the project's master page.
• The hosts on which tasks and daemons are run are specified in the config.xml file.
• Data servers are listed in workunit template files.
• File upload handlers are listed in result template files.
• Your web server runs on the host to which your project URL is mapped.
