|
||
|
||
ejabberd is a distributed, fault-tolerant technology that allows the creation
|
||
of large-scale instant messaging applications. The server can reliably support
|
||
thousands of simultaneous users on a single node and has been designed to
|
||
provide exceptional standards of fault tolerance. As an open source
|
||
technology, based on industry-standards, ejabberd can be used to build bespoke
|
||
solutions very cost effectively.
|
||
|
||
|
||
Key Features
|
||
------------
|
||
|
||
- **Cross-platform**
|
||
ejabberd runs under Microsoft Windows and Unix-derived systems such as
|
||
Linux, FreeBSD and NetBSD.
|
||
|
||
- **Distributed**
|
||
You can run ejabberd on a cluster of machines and all of them will serve the
|
||
same XMPP domain(s). 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.
|
||
|
||
- **Fault-tolerant**
|
||
You can deploy an ejabberd 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’.
|
||
|
||
- **Administrator-friendly**
|
||
ejabberd 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.
|
||
Other administrator benefits include:
|
||
- Comprehensive documentation.
|
||
- Straightforward installers for Linux.
|
||
- Docker packaging to help with deploy / development on Linux, Windows or MacOS.
|
||
- Deb and RPM packaging to support most Linux distributions.
|
||
- Web administration.
|
||
- Shared roster groups.
|
||
- Command line administration tool.
|
||
- Can integrate with existing authentication mechanisms.
|
||
- Capability to send announce messages.
|
||
|
||
- **Internationalized**
|
||
ejabberd leads in internationalization. Hence it is very well suited in a
|
||
globalized world. Related features are:
|
||
- Translated to 25 languages.
|
||
- Support for IDNA.
|
||
|
||
- **Open Standards**
|
||
ejabberd is the first Open Source XMPP server claiming to fully comply to
|
||
the XMPP standard.
|
||
- Fully XMPP-compliant.
|
||
- XML-based protocol.
|
||
- Many protocols supported.
|
||
|
||
|
||

Quickstart guide
|
||
----------------
|
||
|
||
### 0. Requirements
|
||
|
||
To compile ejabberd you need:
|
||
|
||
- GNU Make.
|
||
- GCC.
|
||
- Libexpat ≥ 1.95.
|
||
- Libyaml ≥ 0.1.4.
|
||
- Erlang/OTP ≥ 19.3.
|
||
- OpenSSL ≥ 1.0.0.
|
||
- Zlib ≥ 1.2.3, for Stream Compression support (XEP-0138). Optional.
|
||
- PAM library. Optional. For Pluggable Authentication Modules (PAM).
|
||
- ImageMagick's Convert program and Ghostscript fonts. Optional. For CAPTCHA
|
||
challenges.
|
||
- Elixir ≥ 1.10.3. Optional. Alternative to build ejabberd
|
||
|
||
If your system splits packages in libraries and development headers, you must
|
||
install the development packages also.
|
||
|
||
### 1. Compile and install on *nix systems
|
||
|
||
To compile ejabberd, execute the following commands. The first one is only
|
||
necessary if your source tree didn't come with a `configure` script (In this
|
||
case you need autoconf installed).
|
||
|
||
./autogen.sh
|
||
./configure
|
||
make
|
||
|
||
To install ejabberd, run this command with system administrator rights (root
|
||
user):
|
||
|
||
sudo make install
|
||
|
||
These commands will:
|
||
|
||
- Install the configuration files in `/etc/ejabberd/`
|
||
- Install ejabberd binary, header and runtime files in `/lib/ejabberd/`
|
||
- Install the administration script: `/sbin/ejabberdctl`
|
||
- Install ejabberd documentation in `/share/doc/ejabberd/`
|
||
- Create a spool directory: `/var/lib/ejabberd/`
|
||
- Create a directory for log files: `/var/log/ejabberd/`
|
||
|
||
|
||
### 2. Start ejabberd
|
||
|
||
You can use the `ejabberdctl` command line administration script to
|
||
start and stop ejabberd. For example:
|
||
|
||
ejabberdctl start
|
||
|
||
|
||
For detailed information please refer to the
|
||
[ejabberd Documentation](https://docs.ejabberd.im)
|
||
|
||
|
||
### 3. Use ejabberd locally
|
||
|
||
Alternatively, you can setup ejabberd without installing in your system:
|
||
|
||
./configure --with-rebar=rebar3
|
||
make dev
|
||
|
||
Or, if you have Elixir available and plan to develop Elixir code:
|
||
|
||
./configure --with-rebar=mix
|
||
make dev
|
||
|
||
Check the full list of targets:
|
||
|
||
make help
|
||
|
||
|
||
Development
|
||
-----------
|
||
|
||
In order to assist in the development of ejabberd, and particularly the
|
||
execution of the test suite, a Vagrant environment is available at
|
||
https://github.com/processone/ejabberd-vagrant-dev.
|
||
|
||
To start ejabberd in development mode from the repository directory, you can
|
||
type a command like:
|
||
|
||
EJABBERD_CONFIG_PATH=ejabberd.yml erl -pa ebin -pa deps/*/ebin -pa test -pa deps/elixir/lib/*/ebin/ -s ejabberd
|
||
|
||
|
||
Translation
|
||
-----------
|
||
|
||
Using any gettext editor, you can improve the translation files found in
|
||
`priv/msgs/*.po`, and then submit your changes.
|
||
|
||
Alternatively, a simple way to improve translations is using our Weblate project:
