MongooseIM is Erlang Solutions' robust and efficient XMPP server aimed at large installations. Specifically designed for enterprise purposes, it is fault-tolerant, can utilize resources of multiple clustered machines and easily scale in need of more capacity (by just adding a box/VM).
MongooseIM can accept client sessions over vanilla XMPP, Websockets, and HTTP long-polling (a.k.a. BOSH).
Its home on GitHub is at http://github.com/esl/MongooseIM.
The product page is available at https://www.erlang-solutions.com/products/mongooseim.html
For a quick start just download the pre-built package that suits your platform: Ubuntu, Debian, CentOS, and Mac OS X.
An experimental Docker image exists on: https://registry.hub.docker.com/u/mongooseim/mongooseim-docker/ You can contribute on: https://github.com/ppikula/mongooseim-docker
Main differences from the parent project
This project began its life as a fork of ejabberd v.2.1.8 back in 2011, and later underwent some major cleanup, refactorization and optimization.
Major steps performed at that time:
- bringing the project source tree to compliance with OTP project structure recommendations,
autotoolsfor the Erlang community-standard build tool
- removal of obsolete and/or rarely used modules to reduce maintenance burden,
- reduction of runtime memory consumption by refactoring the code to use Erlang's binary data type for string manipulation and storage instead of operating on linked lists of characters,
- functional test coverage of the system according to corresponding RFCs and XEPs.
Key differences today:
- massive scalability
- code quality, through extensive refactoring, subtantial optimisations, and continuous integration
- unique version, fully open source, fully open standards, innovations contributed to the XSF
- professional support, and flexible customer service
Up-to-date documentation for the MongooseIM master branch can be found on ReadTheDocs:
- Older versions:
When developing new features/modules, please take care to add basic documentation
doc/ directory, and add a link to your document in
Original documentation for Ejabberd-2.1.8, from which MongooseIM was forked, is preserved
Features and supported standards
- XMPP Core: RFC 3920, RFC 6120
- Client connections over TCP (with TLS/STARTTLS available), Websockets, and HTTP(S) (BOSH).
- Configurable database backends: MySQL, Postgres, generic ODBC. Mnesia and Redis for transient data.
- Supports XEPs:
How to build
To compile MongooseIM you need:
- GNU Make,
- Libexpat 1.95 or higher,
- Erlang/OTP 17.5 or higher,
- Reltool 0.6.6 or higher,
- OpenSSL 0.9.8 or higher, for STARTTLS, SASL and SSL encryption,
- Zlib 1.2.3 or higher for Stream Compression support (XEP-0138). Optional.
Compiling on UNIX-like systems.
To compile MongooseIM, go to the main repo directory
$REPOand execute the command (
$stands for the shell prompt):
$ ./rebar get-deps $ ./rebar compile
To generate full MongooseIM release (with mysql, pgsql or other deps):
$ make rel
If more advanced release is required (with some specific db support only, f.e. mysql or pgsql) or you want to set
userfor the installation script please refer to the release configuration page in our documentation
make relcommands will generate a self-contained OTP system image in the project's
rel/mongooseimsubdirectory. The contents of that directory are as follows:
rel/mongooseim/bin- startup/administration scripts,
rel/mongooseim/etc- configuration files,
rel/mongooseim/lib- MongooseIM binary, header and runtime files,
rel/mongooseim/var- spool directory,
rel/mongooseim/log- log file directory,
rel/mongooseim/releases- release files directory.
To run MongooseIM from the project tree after compiling it, change to
There you can use the
mongooseimcommand line administration script to start and stop MongooseIM. For example:
$ bin/mongooseim start
will start the server.
You can also run the server in interactive mode:
$ bin/mongooseim live
There's also a tool called
mongooseimctlallowing you to perform some operations on a running instance, e.g.:
$ bin/mongooseimctl status MongooseIM node mongooseim@localhost: operating system pid: 86026 Erlang VM status: started (of: starting | started | stopping) boot script status: started version: 1.6.2-61-g48b8332 uptime: 1:12:46 logs: log/ejabberd.log
Building the testing target and running tests.
For testing purposes there's a different make target available:
$ make devrel
which will generate releases in
$REPO/dev/and prepare them for testing and generating coverage reports.
To run the tests (from project's root directory, i.e.
$ dev/mongooseim_node1/bin/mongooseim start $ dev/mongooseim_node2/bin/mongooseim start $ make quicktest
The test results will show up in the console`.
