MongooseIM (previously esl-ejabberd) 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). It provides support for WebSockets and reimplemented BOSH.
Its home at GitHub is http://github.com/esl/MongooseIM.
For a quick start just download the pre-built package that suits your platform.
This project began its life as a fork of ejabberd v.2.1.8 and later underwent some major cleanup, refactorization and optimization.
Major steps performed:
- 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.
To compile MongooseIM you need:
- GNU Make,
- Libexpat 1.95 or higher,
- Erlang/OTP R15B or higher,
- Reltool 0.5.4 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,
- PAM library. Optional. For Pluggable Authentication Modules (PAM).
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 MongooseIM release:
$ make rel
$ ./rebar generate
These commands 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 The node mongooseim@localhost is started with status: started MongooseIM version 1.3.1 is running on that node
Building the testing target and running tests.
For testing purposes there's a different make target available:
$ make testrel
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.
$ cd test $ make cover_test
The test results will show up in the console and a coverage report will be generated in
MongooseIM, being a fork of ejabberd, is currently in a phase
of rapid development. Because of that the documentation found in the
subdirectory of the source tree, while mostly relevant, may be inaccurate.
The main reason is that some rarely useful features were removed from the repository or are still waiting to be brought up to the Erlang Solutions standards.
Don't forget to check out our wiki - hopefully, its scope will grow with time.
