MongooseIM

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). It provides support for WebSockets and reimplemented BOSH.

Its home at GitHub is http://github.com/esl/MongooseIM.

Quickstart guide

For a quick start just download the pre-built package that suits your platform.

Main differences from the parent project

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,
• swapping autotools for the Erlang community-standard build tool rebar,
• 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.

How to build

1. Requirements.

   To compile MongooseIM you need:

   • GNU Make,
   • GCC,
   • Libexpat 1.95 or higher,
   • Erlang/OTP R15B02 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).

2. Compiling on UNIX-like systems.

   To compile MongooseIM, go to the main repo directory $REPO and execute the command ($ stands for the shell prompt):

   $ make
   

   or

   $ ./rebar get-deps
   $ ./rebar compile
   

   To generate MongooseIM release:

   $ make rel
   

   or

   $ ./rebar generate
   

   These commands will generate a self-contained OTP system image in the project's rel/mongooseim subdirectory. 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.

3. Running MongooseIM.

   To run MongooseIM from the project tree after compiling it, change to $REPO/rel/mongooseim.

   There you can use the mongooseim command 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 mongooseimctl allowing 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
   

4. 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. $REPO):

   $ cd test
   $ make quicktest
   

   The test results will show up in the console`.

MongooseIM documentation notice

MongooseIM, being a fork of ejabberd, is currently in a phase of rapid development. Because of that the documentation found in the doc/ 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.
