3 # PlanetLab SFA implementation
5 # This implements the SFA Registry and Slice Interfaces on PLC.
6 # Depending on command line options, it starts some combination of a
7 # Registry, an Aggregate Manager, and a Slice Manager.
9 # There are several items that need to be done before starting the servers.
11 # NOTE: Many configuration settings, including the PLC maintenance account
12 # credentials, URI of the PLCAPI, and PLC DB URI and admin credentials are initialized
13 # from your MyPLC configuration (/etc/planetlab/plc_config*). Please make sure this information
14 # is up to date and accurate.
16 # 1) Import the existing planetlab database, creating the
17 # appropriate SFA records. This is done by running the "sfa-import-plc.py" tool.
19 # 2) Create a "trusted_roots" directory and place the certificate of the root
20 # authority in that directory. Given the defaults in sfa-import-plc.py, this
21 # certificate would be named "planetlab.gid". For example,
23 # mkdir trusted_roots; cp authorities/planetlab.gid trusted_roots/
25 # TODO: Can all three servers use the same "registry" certificate?
