<title>DESCRIPTION</title> |

|
50 |
<para> |
51 |
The <command>&dhpackage;</command> is the daemon which is |
52 |
responsible for the node functions in the ganeti system. |
53 |
</para> |
54 |
|
55 |
<para> |
56 |
For testing purposes, you can give the <option>-f</option> |
57 |
option and the program won't detach from the running terminal. |
58 |
</para> |
59 |
|
60 |
<para> |
61 |
Debug-level message can be activated by giving the |
62 |
<option>-d</option> option. |
63 |
</para> |
64 |
|
65 |
<para> |
66 |
Logging to syslog, rather than its own log file, can be enabled by |
67 |
passing in the <option>--syslog</option> option. |
68 |
</para> |
69 |
|
70 |
<para> |
71 |
The ganeti-noded daemon listens to port 1811 TCP, on all interfaces, by |
72 |
default. This can be overridden by an entry in /etc/services or by |
73 |
passing the <option>-p</option> option. The <option>-b</option> option |
74 |
can be used to specify the address to bind to (defaults to 0.0.0.0). |
75 |
</para> |
76 |
|
77 |
<para> |
78 |
Ganeti noded communication is protected via SSL, with a key generated at |
79 |
cluster init time. This can be disabled with the |
80 |
<option>--no-ssl</option> option, or a different ssl key and certificate |
81 |
can be specified using the <option>-K</option> and <option>-C</option> |
82 |
options. |
83 |
</para> |

<title>ROLE</title> |
87 |
<para> |
88 |
The role of the node daemon is to do almost all the actions |
89 |
that change the state of the node. Things like creating disks |
90 |
for instances, activating disks, starting/stopping instance |
91 |
and so on are done via the node daemon. |
92 |
</para> |
93 |
|
94 |
<para> |
95 |
Also, in some cases the startup/shutdown of the master daemon |
96 |
are done via the node daemon, and the cluster IP address is |
97 |
also added/removed to the master node via it. |
98 |
</para> |
99 |
|
100 |
<para> |
101 |
If the node daemon is stopped, the instances are not affected, |
102 |
but the master won't be able to talk to that node. |
103 |
</para> |

<title>COMMUNICATION PROTOCOL</title> |
108 |
<para> |
109 |
Currently the master-node RPC is done using a simple json-RPC |
110 |
over HTTP(S). |
