=head1 DESCRIPTION |
62 |
|
|
|
63 |
root |
1.8 |
With aemp you can configure various aspects of AnyEvent::MP and its |
64 |
root |
1.22 |
protocol, send various messages and even run a node. |
65 |
root |
1.1 |
|

The F<aemp> utility works like F<cvs>, F<svn> or other commands: the first |
67 |
|
|
argument defines which operation (subcommand) is requested, after which |
68 |
|
|
arguments for this operation are expected. When a subcommand does not eat |
69 |
|
|
all remaining arguments, the remaining arguments will again be interpreted |
70 |
|
|
as subcommand and so on. |
71 |
|
|
|
72 |
|
|
This means you can chain multiple commands, which is handy for profile |
73 |
|
|
configuration, e.g.: |
74 |
|
|
|
75 |
|
|
aemp gensecret profile xyzzy setbinds 4040,4041 setnodeid anon/ |

=head2 RUNNING A NODE |
78 |
|
|
|
79 |
|
|
This can be used to run a node - together with some services, this makes |
80 |
|
|
it unnecesary to write any wrapper programs. |

|
|

|
|
=item run <profile> <...> |
85 |
|
|
|
86 |
|
|
Runs a node by calling C<AnyEvent::MP::initialise_node> with the given |
87 |
|
|
arguments. The node runs under L<AnyEvent::Watchdog>, can be restarted |
88 |
|
|
(and autorestarted, see the L<AnyEvent::Watchdog> manual). |
89 |
|
|
|
90 |
|
|
Care has been taken to load (almost) no modules other than |
91 |
|
|
L<AnyEvent::Watchdog> and the modules it loads, so everything (including |
92 |
|
|
the L<AnyEvent::MP> modules themselves) will be freshly loaded on restart, |
93 |
|
|
which makes upgrading everything except the perl binary easy. |

=head2 PROTOCOL COMMANDS |
98 |
|
|
|
99 |
|
|
These commands actually communicate with other nodes. They all use a node |
100 |
root |
1.25 |
profile name of C<aemp> (specifying a dfeault node ID of C<anon/> and a |
101 |
|
|
binds list containing C<*:*> only). |
102 |
root |
1.23 |
|
103 |
|
|
They all use a timeout of five seconds, after which they give up. |
104 |
|
|
|
105 |
|
|
=over 4 |
106 |
|
|
|
107 |
|
|
=item snd <port> <arguments...> |
108 |
|
|
|
109 |
|
|
Simply send a message to the given port - where you get the port ID from |
110 |
|
|
is your problem. |
111 |
|
|
|
112 |
|
|
Exits after ensuring that the message has been delivered to its node. |
113 |
|
|
|
114 |
|
|
Most useful to take avdantage of some undocumented functionality inside |
115 |
|
|
nodes, such as node ports being able to call any method: |
116 |
|
|
|
117 |
|
|
aemp snd doomed AnyEvent::Watchdog::restart 1 |
118 |
|
|
|
119 |
|
|
=item rpc <port> <arg...> |
120 |
|
|
|
121 |
|
|
Like F<aemp snd>, but appends a local reply port to the message and waits |
122 |
|
|
for a message to it. |
123 |
|
|
|
124 |
|
|
Any return values will be JSON-encoded and printed separated by commas |
125 |
|
|
(kind of like a JSON array without []-brackets). |
126 |
|
|
|
127 |
|
|
Example: ask the (undocumented) time service of a node for it'S current |
128 |
|
|
time. |
129 |
|
|
|
130 |
|
|
aemp rpc mynode time |
131 |
|
|
|
132 |
|
|
=item mon <port> |
133 |
|
|
|
134 |
|
|
Monitors the port and exits when it's monitorign callback is called. Most |
135 |
|
|
useful to monitor node ports. |
136 |
|
|
|
137 |
|
|
Example: monitor some node. |

|
|
|
141 |
|
|
=item eval <node> <expr...> |
142 |
|
|
|
143 |
|
|
Joins all remaining arguments into a string and evaluates it on the given |
144 |
|
|
node. Return values are handled as with F<aemp rpc>. |
145 |
|
|
|
146 |
|
|
Example: find the unix process ID of the node called posicks. |
147 |
|
|
|
148 |
|
|
aemp eval posicks '$$' |
149 |
|
|
|
150 |
|
|
=item trace <node> |
151 |
|
|
|
152 |
|
|
Asks the given node for all currently connected nodes, then asks those |
153 |
|
|
nodes for the same, thus tracing all node connections. |

=head2 CONFIGURATION/NODE ID/SECRET/CERTIFICATE |
158 |
|
|
|
159 |
|
|
These commands deal with rather basic settings, the node ID, the shared |
160 |
|
|
secret and the TLS certificate. |
161 |
|
|
|
162 |
|

|
|
|

|
|
=item setnodeid <nodeid> |
165 |
|
|
|
166 |
|
|
Set the node ID to the given string. |
167 |
|
|
|
168 |
|
|
=item delnodeid |
169 |
|
|
|
170 |
|
|
Removes the node ID again, which means it is inherited again from it's |
171 |
|
|
parent profile, or stays unset. |
172 |
|
|
|
173 |
|
|
=item gensecret |
174 |
|
|
|
175 |
|
|
Generates a random shared secret and sets it. The shared secret is used to |
176 |
|
|
authenticate nodes to each other when TLS is not required. |
177 |
|
|
|
178 |
|
|
=item setsecret <secret> |
179 |
|
|
|
180 |
|
|
Sets the shared secret tot he given string, which can be anything. |
181 |
|
|
|
182 |
|
|
=item delsecret |
183 |
|
|
|
184 |
|
|
Removes the shared secret again, which means it is inherited again from |
185 |
|
|
it's parent profile, or stays unset. |
186 |
|
|
|
187 |
|
|
=item gencert |
188 |
|
|
|
189 |
|
|
Generates a self-signed certficate and key, and sets it. This works |
190 |
|
|
similarly to a shared secret: when all nodes have it, TLS will be used to |
191 |
|
|
authenticate and encrypt all traffic. |
192 |
|
|
|
193 |
|
|
=item setcert <file> |
194 |
|
|
|
195 |
|
|
Set a node certificate (and optionally any CA certificates) from the given |
196 |
|
|
file. The file must contain the key, followed by the certificate, followed |
197 |
|
|
by any CA certificates you want to trust, all in PEM format. |
198 |
|
|
|
199 |
|
|
See L<AnyEvent::TLS> for some more details - this sets the C<cert> and |
200 |
|
|
C<ca_cert> options. |
201 |
|
|
|
202 |
|
|
=item delcert |
203 |
|
|
|
204 |
|
|
Removes the certificate(s) again, which means it is inherited again from |
205 |
|
|
it's parent profile, or stays unset. |

=head2 CONFIGURATION/SEEDS |
210 |
|
|
|
211 |
|
|
To discover the network you have to specify some seed addresses, which are |
212 |
|
|
basically C<host:port> pairs where you expect some long-running nodes. It |
213 |
|
|
does no harm to have a node as its own seed (they will eventually be |
214 |
|
|
ignored). |
215 |
|
|
|
216 |
|
|
=item setseeds <host:port>,... |
217 |
|
|
|
218 |
|
|
Sets or replaces the list of seeds, which must be specified as a |
219 |
|
|
comma-separated list of C<host:port> pairs. The C<host> can be a hostname, |
220 |
|
|
an IP address, or C<*> to signify all local host addresses. If the |
221 |
|
|
C<:port> is omitted, then the default port of C<4040> is assumed. |
222 |
|
|
|
223 |
|
|
An empty list is allowed. |
224 |
|
|
|
225 |
|
|
Example: use C<doomed> with default port as only seednode. |

=head2 CONFIGURATION/BINDS |
245 |
|
|
|
246 |
|
|
To be able to be reached from other nodes, a node must I<bind> itself |
247 |
|
|
to some listening socket(s). The list of these can either bs specified |
248 |
|
|
manually, or AnyEvent::MP can guess them. Nodes without any binds are |
249 |
|
|
possible to some extent. |

253 |
|
|
=item setbinds <host:port>,... |
254 |
|
|
|
255 |
|
|
Sets the list of bind addresses explicitly - see the F<aemp setseeds> |
256 |
|
|
command for the exact syntax. In addition, a value of C<0> for the port |
257 |
|
|
means to use a dynamically-assigned port. |
258 |

|
|

=head2 CONFIGURATION/SERVICES |
290 |
|
|
|
291 |
|
|
Services are modules (or functions) that are automatically loaded (or |
292 |
|
|
executed) when a node starts. They are especially useful when used in |
293 |
|
|
conjunction with F<aemp run>, to configure which services a node should |
294 |
|
|
run. |

301 |
|
|
comma-separated list. |
302 |
|
|
|
303 |
|
|
Each entry in the list is interpreted as either a module name to |
304 |
|
|
load (when it ends with C<::>) or a function to call (all other |
305 |
|
|
cases). The algorithm to find the function is the same as used for C<< |
306 |
|
|
L<AnyEvent::MP>::spawn >>. |

=head2 CONFIGURATION/PROFILE MANAGEMENT |
324 |
|
|
|
325 |
|
|
All the above configuration functions by default affect the I<global |
326 |
|
|
default configuration>, which is basically used to augment every profile |
327 |
|
|
and node configuration. |

333 |
|
|
This subcommand makes the following subcommands act only on a specific |
334 |
|
|
named profile, instead of on the global default. The profile is created if |
335 |
|
|
necessary. |
336 |
|
|
|
337 |
|
|
Example: create a C<server> profile, give it a random node name, some seed |
338 |
|
|
nodes and bind it on an unspecified port on all local interfaces. You |
339 |
|
|
should add some services then and run the node... |

Sets the parent profile to use - values not specified in a profile will be |
350 |
|
|
taken from the parent profile (even recursively, with the global default |
351 |
|
|
config being the default parent). This is useful to configure profile |
352 |
|
|
I<classes> and then to inherit from them for individual nodes. |

Note that you can specify circular parent chains and even a parent for the |
355 |
|
|
global configuration. Neither will do you any good, however. |
356 |
|
|
|
357 |
|
|
Example: inherit all values not specified in the C<doomed> profile from |
358 |
|
|
the C<server> profile. |
359 |
|
|
|
360 |
|
|
aemp profile doomed parent server |
361 |
|
|
|
362 |
|
|
=item delparent |
363 |
|
|
|
364 |
|
|
Removes the parent again from the profile, if any was set, so the profile |
365 |
|
|
inherits directly from the global default config again. |
366 |

|
|
367 |
root |
1.23 |
=item showprofile <name> |
368 |
|
|
|
369 |
|
|
Shows the values of the given profile, and only those, no inherited |
370 |
|
|
values. |
371 |
|
|
|
372 |
root |
1.25 |
=item showconfig <name> <key value...> |
373 |
root |
1.23 |
|
374 |
root |
1.24 |
Shows the I<effective> config, i.e. the values as used by a node started |
375 |
root |
1.25 |
with the given profile name. Any additional key-value pairs specified |
376 |
|
|
augment the configuration, just as with C<initialise_node>. |
377 |

1.24 |
