1 This installation note assumes that you have installed and configured MyPLC in the usual manner, and you have set up your yum repo like for a MyPLC install.
3 1) Install the SFA packages:
5 # yum install sfa-plc sfa-client
7 Note that the above command installs both sfa server (sfa-plc) and sfa client packages along with necessary dependency packages. Depending on the requirements, you may choose to install the appropriate one (server, client or both) for you. For e.g. to set up your own SFA server on top of your MyPLC, you need sfa-plc. On the other hand, if you plan to use an existing SFA server, you would typically need the sfa-client only.
9 2) Note down the PLC_ROOT_USER, PLC_ROOT_PASSWORD, PLC_DB_USER and PLC_DB_PASSWORD of your MyPLC installation:
12 Enter command (u for usual changes, w to save, ? for help) s PLC_ROOT_USER
13 PLC_ROOT_USER = root@test.onelab.eu
14 Enter command (u for usual changes, w to save, ? for help) s PLC_ROOT_PASSWORD
15 PLC_ROOT_PASSWORD = test++
16 Enter command (u for usual changes, w to save, ? for help) s PLC_DB_USER
17 PLC_DB_USER = pgsqluser
18 Enter command (u for usual changes, w to save, ? for help) s PLC_DB_PASSWORD
19 PLC_DB_PASSWORD = 4a333aba-a322-41b1-9c05-90b4f34d1332
21 These four configuration parameters are required for SFA server configuration
23 3) Configure and start SFA servers:
27 set SFA_PLC_USER to PLC_ROOT_USER
28 set SFA_PLC_PASSWORD to PLC_ROOT_PASSWORD
29 set SFA_PLC_DB_USER to PLC_DB_USER
30 set SFA_PLC_DB_PASSWORD to PLC_DB_PASSWORD
33 *NOTE* at this point you get a warning b/c the authorities hierarchy has not been created yet; ignore
35 (b) # sfa-import-plc.py
37 (o/p will look like this)
38 Import: creating top level authorities
39 Hierarchy: creating authority: plc
41 Import: creating table for authority plc
42 NOTICE: table "sfa$plc" does not exist, skipping
43 inserting authority record for plc
44 Import: adding plc to trusted list
45 Import_Site: importing site plc.internet2
46 Hierarchy: creating authority: plc.internet2
47 inserting authority record for plc.internet2
48 Import_Site: importing site plc.pl
49 Hierarchy: creating authority: plc.pl
50 inserting authority record for plc.pl
51 Import: importing person plc.pl.root
52 Import: creating table for authority plc.pl
53 NOTICE: table "sfa$plc$pl" does not exist, skipping
55 (c) # service sfa start
57 This will start Registry, Slice Manager and Aggregate Manager. Your ps command output would look like:
59 # ps -ef | grep python
60 root 24944 1 0 May11 ? 00:00:00 /usr/bin/python /usr/bin/sfa-server.py -r -d
61 root 24957 1 0 May11 ? 00:00:00 /usr/bin/python /usr/bin/sfa-server.py -a -d
62 root 24970 1 0 May11 ? 00:00:00 /usr/bin/python /usr/bin/sfa-server.py -s -d
64 4) Configure SFA client:
67 (b)copy your private key to ~/.sfi/username.pkey Replace username with your actual account name
68 (c) # cp /etc/sfa/sfi_config ~/.sfi/
69 (d) edit ~/.sfi/sfi_config. A sample configuration looks like:
71 export SFI_AUTH=plc.pl
72 export SFI_USER=plc.pl.root
73 export SFI_REGISTRY=http://vplc25.inria.fr:12345/
74 export SFI_SM=http://vplc25.inria.fr:12347/
76 (e) # source ~/.sfi/sfi_config
80 At this stage you should be able to run sfi command. Some sample outputs are:
82 (a) # sfi.py list plc.pl
83 plc.pl.netflow (slice)
88 (b) # sfi.py show plc.pl.pif
91 uuid: 99878316891261700702442883738232624912
95 hostname: pif.inria.fr
97 (c) # sfi.py show plc.pl.root
100 uuid: 67306954103472941609600457537601239401
103 last_name: Administrator
105 key: plc.pl.root#user
107 email: root@vplc25.inria.fr
113 (e) # sfi.py resources
114 <?xml version="1.0" ?>
115 <Rspec duration="3600" start_time="1246736949"><networks><NetSpec duration="3600" name="plc" start_time="1246736950"><nodes><NodeSpec cpu_min="" cpu_pct="" cpu_share="" disk_max="" duration="" init_params="" name="pif.inria.fr" start_time="" type=""><net_if><IfSpec addr="138.96.250.224" init_params="" ip_spoof="" max_kbyte="" max_rate="" min_rate="" name="True" type="ipv4"/></net_if></NodeSpec></nodes></NetSpec></networks></Rspec>
118 6) Federation configuration:
120 (a) Follow the same procedure to install and configure second MyPLC with SFA server.
121 (b) On each PLC, edit the /etc/sfa/registries.xml file
123 set addr to ip or hostname of federated (remote) peer
124 set port to sfa service port on federated (remote) peer
125 set hrn to human readable name of federated (remote) peer interface
126 Sample configuration:
129 <registry addr="vplc26.inria.fr" hrn="ple" port="12345"/>
132 (c) Likewise, edit the /etc/sfa/aggregates.xml
136 <aggregate addr="vplc26.inria.fr" hrn="ple" port="12346"/>
139 (d) trade trusted root gid's (seen on /etc/sfa/trusted_roots)
140 we have to copy the gid of first SFA server to the /etc/sfa/trusted_roots directory of second one and vice-versa.
