=head1 DESCRIPTION |
62 |
|
63 |
With aemp you can configure various aspects of AnyEvent::MP and its |
64 |
protocol, send various messages and even run a node. |
65 |
|
66 |
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 binds 4040,4041 nodeid anon/ |
76 |
|
77 |
Please note that all C<setxxx> subcommands have an alias without the |
78 |
C<set> prefix. |
79 |
|
80 |
=head2 RUNNING A NODE |
81 |
|
82 |
This can be used to run a node - together with some services, this makes |
83 |
it unnecessary to write any wrapper programs. |
84 |
|
85 |
=over 4 |
86 |
|
87 |
=item run <configure_args>... |
88 |
|
89 |
Runs a node by calling C<AnyEvent::MP::Kernel::configure> with the given |
90 |
arguments. The node runs under L<AnyEvent::Watchdog>, can be restarted |
91 |
(and autorestarted, see the L<AnyEvent::Watchdog> manual). A very common |
92 |
invocation is to just specify a profile using the profile name |
93 |
|
94 |
aemp run database-backend |
95 |
|
96 |
... but you can use most arguments that C<configure> understands: |
97 |
|
98 |
aemp run nodeid mynode2 profile someprofile |
99 |
|
100 |
Care has been taken to load (almost) no modules other than |
101 |
L<AnyEvent::Watchdog> and the modules it loads, so everything (including |
102 |
the L<AnyEvent::MP> modules themselves) will be freshly loaded on restart, |
103 |
which makes upgrading everything except the perl binary easy. |
104 |
|
105 |
=back |
106 |
|
107 |
=head2 PROTOCOL COMMANDS |
108 |
|
109 |
These commands actually communicate with other nodes. They all use a node |
110 |
profile name of C<aemp> (specifying a default node ID of C<anon/> and a |
111 |
binds list containing C<*:*> only). |
112 |
|
113 |
They all use a timeout of five seconds, after which they give up. |
114 |
|
115 |
=over 4 |
116 |
|
117 |
=item snd <port> <arguments...> |
118 |
|
119 |
Simply send a message to the given port - where you get the port ID from |
120 |
is your problem. |
121 |
|
122 |
Exits after ensuring that the message has been delivered to its node. |
123 |
|
124 |
Most useful to take advantage of some undocumented functionality inside |
125 |
nodes, such as node ports being able to call any method: |
126 |
|
127 |
aemp snd doomed AnyEvent::Watchdog::restart 1 |
128 |
|
129 |
=item rpc <port> <arg...> |
130 |
|
131 |
Like F<aemp snd>, but appends a local reply port to the message and waits |
132 |
for a message to it. |
133 |
|
134 |
Any return values will be JSON-encoded and printed separated by commas |
135 |
(kind of like a JSON array without []-brackets). |
136 |
|
137 |
Example: ask the (undocumented) time service of a node for it's current |
138 |
time. |
139 |
|
140 |
aemp rpc mynode time |
141 |
|
142 |
=item mon <port> |
143 |
|
144 |
Monitors the port and exits when it's monitorign callback is called. Most |
145 |
useful to monitor node ports. |
146 |
|
147 |
Example: monitor some node. |
148 |
|
149 |
aemp mon doomed |
150 |
|
151 |
=item eval <node> <expr...> |
152 |
|
153 |
Joins all remaining arguments into a string and evaluates it on the given |
154 |
node. Return values are handled as with F<aemp rpc>. |
155 |
|
156 |
Example: find the unix process ID of the node called posicks. |
157 |
|
158 |
aemp eval posicks '$$' |
159 |
|
160 |
=item trace <node> |
161 |
|
162 |
Asks the given node for all currently connected nodes, then asks those |
163 |
nodes for the same, thus tracing all node connections. |
164 |
|
165 |
=back |
166 |
|
167 |
=head2 CONFIGURATION/NODE ID/SECRET/CERTIFICATE |
168 |
|
169 |
These commands deal with rather basic settings, the node ID, the shared |
170 |
secret and the TLS certificate. |
171 |
|
172 |
=over 4 |
173 |
|
174 |
=item setnodeid <nodeid> |
175 |
|
176 |
Set the node ID to the given string. |
177 |
|
178 |
=item delnodeid |
179 |
|
180 |
Removes the node ID again, which means it is inherited again from it's |
181 |
parent profile, or stays unset. |
182 |
|
183 |
=item gensecret |
184 |
|
185 |
Generates a random shared secret and sets it. The shared secret is used to |
186 |
authenticate nodes to each other when TLS is not required. |
187 |
|
188 |
=item setsecret <secret> |
189 |
|
190 |
Sets the shared secret tot he given string, which can be anything. |
191 |
|
192 |
=item delsecret |
193 |
|
194 |
Removes the shared secret again, which means it is inherited again from |
195 |
it's parent profile, or stays unset. |
196 |
|
197 |
=item gencert |
198 |
|
199 |
Generates a self-signed certificate and key, and sets it. This works |
200 |
similarly to a shared secret: when all nodes have it, TLS will be used to |
201 |
authenticate and encrypt all traffic. |
202 |
|
203 |
=item setcert <file> |
204 |
|
205 |
Set a node certificate (and optionally any CA certificates) from the given |
206 |
file. The file must contain the key, followed by the certificate, followed |
207 |
by any CA certificates you want to trust, all in PEM format. |
208 |
|
209 |
See L<AnyEvent::TLS> for some more details - this sets the C<cert> and |
210 |
C<ca_cert> options. |
211 |
|
212 |
=item delcert |
213 |
|
214 |
Removes the certificate(s) again, which means it is inherited again from |
215 |
it's parent profile, or stays unset. |
216 |
|
217 |
=back |
218 |
|
219 |
=head2 CONFIGURATION/SEEDS |
220 |
|
221 |
To discover the network you have to specify some seed addresses, which are |
222 |
basically C<host:port> pairs where you expect some long-running nodes. It |
223 |
does no harm to have a node as its own seed (they will eventually be |
224 |
ignored). |
225 |
|
226 |
=over 4 |
227 |
|
228 |
=item setseeds <host:port>,... |
229 |
|
230 |
Sets or replaces the list of seeds, which must be specified as a |
231 |
comma-separated list of C<host:port> pairs. The C<host> can be a hostname, |
232 |
an IP address, or C<*> to signify all local host addresses. If the |
233 |
C<:port> is omitted, then the default port of C<4040> is assumed. |
234 |
|
235 |
An empty list is allowed. |
236 |
|
237 |
Example: use C<doomed> with default port as only seednode. |
238 |
|
239 |
aemp setseeds doomed |
240 |
|
241 |
=item delseeds |
242 |
|
243 |
Removes the seed list again, which means it is inherited again from it's |
244 |
parent profile, or stays unset. |
245 |
|
246 |
=item addseed <host:port> |
247 |
|
248 |
Adds a single seed address. |
249 |
|
250 |
=item delseed <host:port> |
251 |
|
252 |
Deletes the given seed address, if it exists. |
253 |
|
254 |
=back |
255 |
|
256 |
=head2 CONFIGURATION/BINDS |
257 |
|
258 |
To be able to be reached from other nodes, a node must I<bind> itself |
259 |
to some listening socket(s). The list of these can either bs specified |
260 |
manually, or AnyEvent::MP can guess them. Nodes without any binds are |
261 |
possible to some extent. |
262 |
|
263 |
=over 4 |
264 |
|
265 |
=item setbinds <host:port>,... |
266 |
|
267 |
Sets the list of bind addresses explicitly - see the F<aemp setseeds> |
268 |
command for the exact syntax. In addition, a value of C<0> for the port |
269 |
means to use a dynamically-assigned port. |
270 |
|
271 |
Note that the C<*>, C<*:*> or C<*:port> values are very useful here. |
272 |
|
273 |
Example: bind on the default port (4040) on all local interfaces. |
274 |
|
275 |
aemp setbinds "*" |
276 |
|
277 |
Example: bind on a random port on all local interfaces. |
278 |
|
279 |
aemp setbinds "*:*" |
280 |
|
281 |
Example: resolve "doomed.mydomain" and try to bind on port C<4040> of all |
282 |
IP addressess returned. |
283 |
|
284 |
aep setbinds doomed.mydomain |
285 |
|
286 |
=item delbinds |
287 |
|
288 |
Removes the bind list again, which means it is inherited again from it's |
289 |
parent profile, or stays unset. |
290 |
|
291 |
=item addbind <host:port> |
292 |
|
293 |
Adds a single bind address. |
294 |
|
295 |
=item delbind <host:port> |
296 |
|
297 |
Deletes the given bind address, if it exists. |
298 |
|
299 |
=back |
300 |
|
301 |
=head2 CONFIGURATION/SERVICES |
302 |
|
303 |
Services are modules (or functions) that are automatically loaded (or |
304 |
executed) when a node starts. They are especially useful when used in |
305 |
conjunction with F<aemp run>, to configure which services a node should |
306 |
run. |
307 |
|
308 |
=over 4 |
309 |
|
310 |
=item setservices <initfunc>... |
311 |
|
312 |
Sets or replaces the list of services, which must be specified as a |
313 |
comma-separated list. |
314 |
|
315 |
Each entry in the list is interpreted as either a module name to |
316 |
load (when it ends with C<::>) or a function to call (all other |
317 |
cases). The algorithm to find the function is the same as used for C<< |
318 |
L<AnyEvent::MP>::spawn >>. |
319 |
|
320 |
=item delservices |
321 |
|
322 |
Removes the service list again, which means it is inherited again from |
323 |
it's parent profile, or stays unset. |
324 |
|
325 |
=item addservice <initfunc> |
326 |
|
327 |
Adds a single service. |
328 |
|
329 |
=item delservice <initfunc> |
330 |
|
331 |
Deletes the given service, if it exists. |
332 |
|
333 |
=back |
334 |
|
335 |
=head2 CONFIGURATION/PROFILE MANAGEMENT |
336 |
|
337 |
All the above configuration functions by default affect the I<global |
338 |
default configuration>, which is basically used to augment every profile |
339 |
and node configuration. |
340 |
|
341 |
=over 4 |
342 |
|
343 |
=item profile <name> ... |
344 |
|
345 |
This subcommand makes the following subcommands act only on a specific |
346 |
named profile, instead of on the global default. The profile is created if |
347 |
necessary. |
348 |
|
349 |
Example: create a C<server> profile, give it a random node name, some seed |
350 |
nodes and bind it on an unspecified port on all local interfaces. You |
351 |
should add some services then and run the node... |
352 |
|
353 |
aemp profile server nodeid anon/ seeds doomed,10.0.0.2:5000 binds "*:*" |
354 |
|
355 |
=item delprofile <name> |
356 |
|
357 |
Deletes the profile of the given name. |
358 |
|
359 |
=item setparent <name> |
360 |
|
361 |
Sets the parent profile to use - values not specified in a profile will be |
362 |
taken from the parent profile (even recursively, with the global default |
363 |
config being the default parent). This is useful to configure profile |
364 |
I<classes> and then to inherit from them for individual nodes. |
365 |
|
366 |
Note that you can specify circular parent chains and even a parent for the |
367 |
global configuration. Neither will do you any good, however. |
368 |
|
369 |
Example: inherit all values not specified in the C<doomed> profile from |
370 |
the C<server> profile. |
371 |
|
372 |
aemp profile doomed setparent server |
373 |
|
374 |
=item delparent |
375 |
|
376 |
Removes the parent again from the profile, if any was set, so the profile |
377 |
inherits directly from the global default config again. |
378 |
|
379 |
=item showprofile <name> |
380 |
|
381 |
Shows the values of the given profile, and only those, no inherited |
382 |
values. |
383 |
|
384 |
=item showconfig <name> <key value...> |
385 |
|
386 |
Shows the I<effective> config, i.e. the values as used by a node started |
387 |
with the given profile name. Any additional key-value pairs specified |
388 |
augment the configuration, just as with C<configure>. |
389 |
|
390 |
If all arguments are omitted, show the global default config. |
