<TT>ejabberd</TT> is a Free and Open Source fault-tolerant distributed Jabber
|
2004-07-06 23:34:50 +02:00
|
|
|
server. It is written mostly in Erlang.<BR>

The main features of <TT>ejabberd</TT> are:

|
|
|
<UL><LI>
|
2003-10-12 20:21:16 +02:00

|
Works on most of popular platforms: *nix (tested on Linux, FreeBSD and
|
|
|
|
|
NetBSD) and Win32
|
2004-07-06 23:34:50 +02:00
|
|
|
<LI>Distributed: You can run <TT>ejabberd</TT> on a cluster of machines to let all of
|
|
|
|
|
them serve one Jabber domain.
|
2003-07-14 20:06:03 +02:00
|
|
|
<LI>Fault-tolerance: You can setup an <TT>ejabberd</TT> cluster so that all the
|
2003-02-10 15:31:27 +01:00
|
|
|
information required for a properly working service will be stored
|
2003-07-13 11:00:01 +02:00
|
|
|
permanently on more than one node. This means that if one of the nodes
|
2003-02-11 19:09:14 +01:00
|
|
|
crashes, then the others will continue working without disruption.
|
2004-07-06 23:34:50 +02:00
|
|
|
You can also add or replace nodes ``on the fly''.

To start <TT>ejabberd</TT>, use the following command:
|
|
|
|
|
<PRE>
|
2004-07-06 23:34:50 +02:00
|
|
|
erl -pa /var/lib/ejabberd/ebin -name ejabberd -s ejabberd

name, i. e. other Erlang nodes outside this domain can't contact this node.<BR>

<BR>
|
2004-07-06 23:34:50 +02:00

Note that when using above command <TT>ejabberd</TT> will search for config file

in current directory and will use current directory for storing user database

To specify path to config file, log files and Mnesia database directory,

you may use the following command:

To use more than 1024 connections, you should set environment variable

have the same magic cookie (see Erlang/OTP documentation, in other words the

This module is the main router of Jabber packets on each node. It
|
|
|
|
|
routes them based on their destinations domains. It uses a global
|
|
|
|
|
routing table. A domain of packet destination is searched in the
|
|
|
|
|
routing table, and if it is found, then the packet is routed to
|
|
|
|
|
appropriate process. If no, then it is sent to the S2S manager.<BR>

Suppose you already setuped ejabberd on one of machines (<TT>first</TT>), and
|
|
|
|
|
you need to setup another one to make <TT>ejabberd</TT> cluster. Then do
|
|
|
|
|
following steps:
|
|
|
|
|
<OL type=1><LI>
|
|
|
|
|
Copy <CODE>~ejabberd/.erlang.cookie</CODE> file from <TT>first</TT> to
|
|
|
|
|
<TT>second</TT>.<BR>
|
|
|
|
|
<BR>
|
|
|
|
|
(alt) You can also add ``<CODE>-cookie content_of_.erlang.cookie</CODE>''
|
|
|
|
|
option to all ``<TT>erl</TT>'' commands below.<BR>
|
|
|
|
|
<BR>
|
|
|
|
|
<LI>On <TT>second</TT> run under `<TT>ejabberd</TT>' user in a directory
|
|
|
|
|
where ejabberd will work later the following command:
|
|
|
|
|
<PRE>
|
|
|
|
|
erl -sname ejabberd \
|
|
|
|
|
-mnesia extra_db_nodes "['ejabberd@first']" \
|
|
|
|
|
-s mnesia
|
|
|
|
|
</PRE>This will start mnesia serving same DB as <TT>ejabberd@first</TT>.
|
|
|
|
|
You can check this running ``<CODE>mnesia:info().</CODE>'' command. You
|
|
|
|
|
should see a lot of remote tables and a line like the following:
|
|
|
|
|
<PRE>
|
|
|
|
|
running db nodes = [ejabberd@first, ejabberd@second]
|
|
|
|
|
</PRE>
|
|
|
|
|
|
|
|
|
|
<LI>Now run the following in the same ``<TT>erl</TT>'' session:
|
|
|
|
|
<PRE>
|
|
|
|
|
mnesia:change_table_copy_type(schema, node(), disc_copies).
|
|
|
|
|
</PRE>
|
|
|
|
|
This will create local disc storage for DB.<BR>
|
|
|
|
|
<BR>
|
|
|
|
|
(alt) Change storage type of `<TT>scheme</TT>' table to ``RAM and disc
|
|
|
|
|
copy'' on second node via web interface.<BR>
|
|
|
|
|
<BR>
|
|
|
|
|
<LI>Now you can add replicas of various tables to this node with
|
|
|
|
|
``<CODE>mnesia:add_table_copy</CODE>'' or
|
|
|
|
|
``<CODE>mnesia:change_table_copy_type</CODE>'' as above (just replace
|
|
|
|
|
``<CODE>schema</CODE>'' with another table name and ``<CODE>disc_copies</CODE>''
|
|
|
|
|
can be replaced with ``<CODE>ram_copies</CODE>'' or
|
|
|
|
|
``<CODE>disc_only_copies</CODE>'').<BR>
|
|
|
|
|
<BR>
|
|
|
|
|
What tables to replicate is very depend on your needs, you can get
|
|
|
|
|
some hints from ``<CODE>mnesia:info().</CODE>'' command, by looking at
|
|
|
|
|
size of tables and default storage type for each table on 'first'.<BR>
|
|
|
|
|
<BR>
|
|
|
|
|
Replicating of table makes lookup in this table faster on this node,
|
|
|
|
|
but writing will be slower. And of course if machine with one of
|
|
|
|
|
replicas is down, other replicas will be used.<BR>

can be useful.<BR>
|
|
|
|
|
<BR>
|
|
|
|
|
(alt) Same as in previous item, but for other tables.<BR>
|
|
|
|
|
<BR>
|
|
|
|
|
<LI>Run ``<CODE>init:stop().</CODE>'' or just ``<CODE>q().</CODE>'' to exit from
|
|
|
|
|
erlang shell. This probably can take some time if mnesia is not yet
|
|
|
|
|
transfer and process all data it needed from <TT>first</TT>.<BR>
|
|
|
|
|
<BR>
|
|
|
|
|
<LI>Now run ejabberd on <TT>second</TT> with almost the same config as
|
|
|
|
|
on <TT>first</TT> (you probably don't need to duplicate ``<CODE>acl</CODE>''
|
|
|
|
|
and ``<CODE>access</CODE>'' options --- they will be taken from
|
|
|
|
|
<TT>first</TT>, and <CODE>mod_muc</CODE> and <CODE>mod_irc</CODE> should be
|
|
|
|
|
enabled only on one machine in cluster).
|
|
|
|
|
</OL>
|
|
|
|
|
You can repeat these steps for other machines supposed to serve this
|
|
|
|
|
domain.<BR>

Many modules define handlers for processing IQ queries of different namespaces
|
2003-10-09 20:09:05 +02:00
|
|
|
to this server or to user (e. g. to <TT>example.org</TT> or to
|
|
|
|
|
<TT>user@example.org</TT>). This option defines processing discipline of
|
2003-02-11 19:09:14 +01:00
|
|
|
these queries. Possible values are:
|
2003-02-10 15:31:27 +01:00
|
|
|
<DL COMPACT=compact><DT>
|
|
|
|
|
<B><TT>no_queue</TT></B><DD> All queries of namespace with this processing
|
2003-01-24 21:18:33 +01:00
|
|
|
discipline processed immediately. This also means that no other packets can
|
|
|
|
|
be processed until finished this. Hence this discipline is not recommended
|
2004-07-06 23:34:50 +02:00
|
|
|
if processing of query can take relatively long time.
|
2003-02-10 15:31:27 +01:00
|
|
|
<DT><B><TT>one_queue</TT></B><DD> In this case created separate queue for processing
|
2003-10-11 19:39:36 +02:00
|
|
|
of IQ queries of namespace with this discipline, and processing of this queue
|
|
|
|
|
is done in parallel with processing of other packets. This discipline is most
|
2003-01-24 21:18:33 +01:00
|
|
|
recommended.
|
2003-07-13 11:00:01 +02:00
|
|
|
<DT><B><TT>parallel</TT></B><DD> In this case for all packets with this discipline
|
|
|
|
|
spawned separate Erlang process, so all these packets processed in parallel.
|
2003-10-11 19:39:36 +02:00
|
|
|
Although spawning of Erlang process have relatively low cost, this can broke
|
|
|
|
|
server normal work, because Erlang emulator have limit on number of processes
|
|
|
|
|
(32000 by default).
