<TT>ejabberd</TT> is a free (GPL) distributed fault-tolerant Jabber/XMPP server and is mainly written in <A HREF="http://www.erlang.org/">Erlang</A>.<BR>
|
||
<BR>
|
||
<TT>ejabberd</TT> is designed to be a stable, standards compliant, and feature rich Jabber/XMPP server.<BR>
|
||
<BR>
|
||
<TT>ejabberd</TT> is suitable for small servers, whether they need to be scalable or not, as well as extremely big servers.<BR>

<LI CLASS="li-itemize">Distributed: You can run <TT>ejabberd</TT> on a cluster of machines and all of them will serve one Jabber domain. When you need more capacity you can simply add a new cheap node to your cluster. Accordingly, you do not need to buy an expensive high-end machine to support tens of thousands concurrent users.<BR>
|
||
<BR>
|
||
<LI CLASS="li-itemize">Fault-tolerant: You can deploy an <TT>ejabberd</TT> cluster so that all the information required for a properly working service will be replicated permanently on all nodes. This means that if one of the nodes crashes, the others will continue working without disruption. In addition, nodes also can be added or replaced “on the fly”.<BR>

||
<BR>
|
||
<LI CLASS="li-itemize">Administrator Friendly: <TT>ejabberd</TT> is built on top of the Open Source Erlang. As a result you do not need to install an external database, an external web server, amongst others because everything is already included, and ready to run out of the box.

<PRE CLASS="verbatim">

of the host name, i. e. other Erlang nodes outside this domain can't contact

this node.<BR>
|

<BR>
|

Note that when using the above command, <TT>ejabberd</TT> will search for the
|

configuration file in the current directory and will use the current directory
|
||
for storing its user database and for logging.<BR>
|
||
<BR>
|
||
To specify the path to the configuration file, the log files and the Mnesia
|
||
database directory, you may use the following command:
|
||
<PRE CLASS="verbatim">
|
||
erl -pa /var/lib/ejabberd/ebin \
|
||
-sname ejabberd \
|

|

You can find other useful options in the Erlang manual page
|

(<TT>erl -man erl</TT>).<BR>
|
||
<BR>
|
||
To use more than 1024 connections, you should set the environment variable
|
||
<CODE>ERL_MAX_PORTS</CODE>:
|
||
<PRE CLASS="verbatim">
|
||
export ERL_MAX_PORTS=32000
|
||
</PRE>Note that with this value, <TT>ejabberd</TT> will use more memory (approximately 6 MB
|

more).<BR>
|
||
<BR>
|

To reduce memory usage, you may set the environment variable
|

<CODE>ERL_FULLSWEEP_AFTER</CODE>:
|
||
<PRE CLASS="verbatim">

The configuration file will be loaded the first time you start <TT>ejabberd</TT>. The

content from this file will be parsed and stored in a database. Subsequently the
|

configuration will be loaded from the database and any commands in the
|
||
configuration file are appended to the entries in the database. The
|
||
configuration file contains a sequence of Erlang terms. Lines beginning with a
|
||
<TT>`%'</TT> sign are ignored. Each term is a tuple of which the first element is
|
||
the name of an option, and any further elements are that option's values. If the
|
||
configuration file do not contain for instance the “hosts” option, the old
|
||
host name(s) stored in the database will be used.<BR>
|

<BR>
|

You can override the old values stored in the database by adding next lines to

<PRE CLASS="verbatim">

This module is the main router of Jabber packets on each node. It

Suppose you already configured <TT>ejabberd</TT> on one machine named (<TT>first</TT>),
|
||
and you need to setup another one to make an <TT>ejabberd</TT> cluster. Then do
|
||
following steps:
|
||
<OL CLASS="enumerate" type=1><LI CLASS="li-enumerate">
|
||
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 CLASS="li-enumerate">On <TT>second</TT> run as the `<TT>ejabberd</TT>' user in the directory
|
||
where <TT>ejabberd</TT> will work later the following command:
|
||
<PRE CLASS="verbatim">
|
||
erl -sname ejabberd \
|
||
-mnesia extra_db_nodes "['ejabberd@first']" \
|
||
-s mnesia
|
||
</PRE>
|
||
This will start Mnesia serving the same database as <TT>ejabberd@first</TT>.
|
||
You can check this by running the command “<CODE>mnesia:info().</CODE>”. You
|
||
should see a lot of remote tables and a line like the following:
|
||
<PRE CLASS="verbatim">
|
||
running db nodes = [ejabberd@first, ejabberd@second]
|
||
</PRE><BR>
|
||
<BR>
|
||
<LI CLASS="li-enumerate">Now run the following in the same “<TT>erl</TT>” session:
|
||
<PRE CLASS="verbatim">
|
||
mnesia:change_table_copy_type(schema, node(), disc_copies).
|
||
</PRE>
|
||
This will create local disc storage for the database.<BR>
|
||
<BR>
|
||
(alt) Change storage type of `<TT>scheme</TT>' table to “RAM and disc
|
||
copy” on the second node via the web interface.<BR>
|
||
<BR>
|
||
<LI CLASS="li-enumerate">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>
|
||
Which tables to replicate is very dependant on your needs, you can get
|
||
some hints from the command “<CODE>mnesia:info().</CODE>”, by looking at the
|
||
size of tables and the default storage type for each table on 'first'.<BR>
|
||
<BR>
|
||
Replicating a table makes lookups in this table faster on this node.
|
||
Writing, on the other hand, will be slower. And of course if machine with one
|
||
of the replicas is down, other replicas will be used.<BR>

<BR>
|

<BR>
|

(alt) Same as in previous item, but for other tables.<BR>
|

<BR>
|
||
<LI CLASS="li-enumerate">Run “<CODE>init:stop().</CODE>” or just “<CODE>q().</CODE>” to exit from
|

the Erlang shell. This probably can take some time if Mnesia has not yet
|
||
transfered and processed all data it needed from <TT>first</TT>.<BR>
|
||
<BR>
|
||
<LI CLASS="li-enumerate">Now run <TT>ejabberd</TT> on <TT>second</TT> with almost the same config as
|
||
on <TT>first</TT> (you probably don't need to duplicate “<CODE>acl</CODE>”

<TT>first</TT>, and <CODE>mod_muc</CODE> and <CODE>mod_irc</CODE> should be

Many modules define handlers for processing IQ queries of different namespaces
|
||
to this server or to a user (e. g. to <TT>example.org</TT> or to
|
||
<TT>user@example.org</TT>). This option defines processing discipline for
|
||
these queries. Possible values are:
|
||
<DL CLASS="description" COMPACT=compact><DT CLASS="dt-description">
|
||
<B><TT>no_queue</TT></B><DD CLASS="dd-description"> All queries of a namespace with this processing discipline are
|
||
processed immediately. This also means that no other packets can be processed
|
||
until this one has been completely processed. Hence this discipline is not
|
||
recommended if the processing of a query can take a relatively long time.
|
||
<DT CLASS="dt-description"><B><TT>one_queue</TT></B><DD CLASS="dd-description"> In this case a separate queue is created for the processing
|
||
of IQ queries of a namespace with this discipline. In addition, the processing
|
||
of this queue is done in parallel with that of other packets. This discipline
|
||
is most recommended.
|
||
<DT CLASS="dt-description"><B><TT>parallel</TT></B><DD CLASS="dd-description"> For every packet with this discipline a separate Erlang process
|
||
is spawned. Consequently, all these packets are processed in parallel.
|
||
Although spawning of Erlang process has a relatively low cost, this can break
|
||
the server's normal work, because the Erlang emulator has a limit on the
|
||
number of processes (32000 by default).

This module enables you to create shared roster groups. This means that you can
|
||
create groups of people that can see members from (other) groups in their
|
||
rosters. The big advantages of this feature are that end users do not need to
|
||
manually add all users to their rosters, and that they cannot permanently delete
|
||
users from the shared roster groups.<BR>
|
||
<BR>
|
||
Shared roster groups can be edited <EM>only</EM> via the web interface. Each group
|
||
has a unique identification and the following parameters:
|

<DL CLASS="description" COMPACT=compact><DT CLASS="dt-description">
|
||
<B>Name</B><DD CLASS="dd-description"> The name of the group, which will be displayed in the roster.

<DT CLASS="dt-description"><B>Members</B><DD CLASS="dd-description"> A list of full JIDs of group members, entered one per line in

Release notes
|
||
ejabberd 0.9
|
||
|
||
This document describes the major new features of and changes to
|
||
ejabberd 0.9, compared to latest public release ejabber 0.7.5.
|
||
|
||
For more detailed information, please refer to ejabberd User
|
||
Guide.
|
||
|
||
|
||
Virtual Hosting
|
||
|
||
ejabberd now can host several domain on the same instance.
|
||
This option is enabled by using:
|
||
|
||
{hosts, ["erlang-projects.org", "erlang-fr.org"]}.
|
||
|
||
instead of the previous host directive.
|
||
|
||
Note that you are now using a list of hosts. The main one should
|
||
be the first listed. See migration section further in this release
|
||
note for details.
|
||
|
||
|
||
Shared Roster
|
||
|
||
Shared roster is a new feature that allow the ejabberd
|
||
administrator to add jabber user that will be present in the
|
||
roster of every users on the server.
|
||
Shared roster are enabled by adding:
|
||
|
||
{mod_shared_roster, []}
|
||
|
||
at the end of your module list in your ejabberd.cfg file.
|
||
|
||
|
||
PostgreSQL (ODBC) support
|
||
|
||
This feature is experimental and not yet properly documented. This
|
||
feature is released for testing purpose.
|
||
|
||
You need to have Erlang/OTP R10 to compile with ODBC on various
|
||
flavour of *nix. You should use Erlang/OTP R10B-4, as this task
|
||
has became easier with this release. It comes already build in
|
||
Erlang/OTP Microsoft Windows binary.
|
||
|
||
PostgreSQL support is enabled by using the following module in
|
||
ejabberd.cfg instead of their standard counterpart:
|
||
|
||
mod_last_odbc.erl
|
||
mod_offline_odbc.erl
|
||
mod_roster_odbc.erl
|
||
|
||
The database schema is located in the src/odbc/pq.sql file.
|
||
|
||
Look at the src/ejabberd.cfg.example file for more information on
|
||
how to configure ejabberd with odbc support. You can get support
|
||
on how to configure ejabberd with a relational database.
|
||
|
||
|
||
Migration from ejabberd 0.7.5
|
||
|
||
Migration is pretty straightforward as Mnesia database schema
|
||
conversions is handled automatically. Remember however that you
|
||
must backup your ejabberd database before migration.
|
||
|
||
Here are the following steps to proceed:
|
||
|
||
1. Stop your instance of ejabberd.
|
||
|
||
2. In ejabberd.cfg, define the host lists. Change the host
|
||
directive to the hosts one:
|
||
Before:
|
||
{host, "erlang-projects.org"}.
|
||
After:
|
||
{hosts, ["erlang-projects.org", "erlang-fr.org"]}.
|
||
Note that when you restart the server the existing users will be
|
||
affected to the first virtual host, so the order is important. You
|
||
should keep the previous hostname as the first virtual host.
|
||
|
||
3. Restart ejabberd.
|
||
|
||
|

ejabberd 0.9.8
|
||
2005-08-01
|
||
|
||
This document describes the main changes in ejabberd 0.9.8. This
|
||
version prepares the way for the release of ejabberd 1.0, which
|
||
is due later this year.
|
||
|
||
The code can be downloaded from the Process-one website:
|
||
http://www.process-one.net/en/projects/ejabberd/
|
||
|
||
For more detailed information, please refer to ejabberd User Guide
|
||
on the Process-one website:
|
||
http://www.process-one.net/en/projects/ejabberd/docs.html
|
||
|
||
|
||
Recent changes include....
|
||
|
||
|
||
Enhanced virtual hosting
|
||
|
||
Virtual hosting applies to many more setting options and
|
||
features and is transparent. Virtual hosting accepts different
|
||
parameters for different virtual hosts regarding the following
|
||
features: authentication method, access control lists and access
|
||
rules, users management, statistics, and shared roster. The web
|
||
interface gives access to each virtual host's parameters.
|
||
|
||
|
||
Enhanced Publish-Subscribe module
|
||
|
||
ejabberd's Publish-Subscribe module integrates enhancements
|
||
coming from J-EAI, an XMPP-based integration server built on
|
||
ejabberd. ejabberd thus supports Publish-Subscribe node
|
||
configuration. It is possible to define nodes that should be
|
||
persistent, and the number of items to persist. Besides that, it
|
||
is also possible to define various notification parameters, such
|
||
as the delivery of the payload with the notifications, and the
|
||
notification of subscribers when some changes occur on items.
|
||
Other examples are: the maximum size of the items payload, the
|
||
subscription approvers, the limitation of the notification to
|
||
online users only, etc.
|
||
|
||
|
||
Code reorganisation and update
|
||
|
||
- The mod_register module has been cleaned up.
|
||
- ODBC support has been updated and several bugs have been fixed.
|
||
|
||
|
||
Development API
|
||
|
||
To ease the work of Jabber/XMPP developers, a filter_packet hook
|
||
has been added. As a result it is possible to develop plugins to
|
||
filter or modify packets flowing through ejabberd.
|
||
|
||
|
||
Translations
|
||
|
||
- Translations have been updated to support the new Publish-Subscribe features.
|
||
- A new Brazilian Portuguese translation has been contributed.
|
||
|
||
|
||
Web interface
|
||
|
||
- The CSS stylesheet from the web interface is W3C compliant.
|
||
|
||
|
||
Installers
|
||
|
||
Installers are provided for Microsoft Windows and Linux/x86. The
|
||
Linux installer includes Erlang ASN.1 modules for LDAP
|
||
authentication support.
|
||
|
||
|
||
Bugfixes
|
||
|
||
- This release contains several bugfixes and architectural
|
||
changes. Among other bugfixes include improvements in LDAP
|
||
authentication. Please refer to the ChangeLog file supplied
|
||
with this release regarding all improvements in ejabberd.
