Compile and Install ejabberd
============================
This document explains how to compile and install ejabberd
from source code.
For a more detailed explanation, please check the
ejabberd Docs: [Source Code Installation][docs-source].
[docs-source]: https://docs.ejabberd.im/admin/install/source/
Requirements
------------
To compile ejabberd you need:
- GNU Make
- GCC
- Libexpat ≥ 1.95
- Libyaml ≥ 0.1.4
- Erlang/OTP ≥ 20.0
- OpenSSL ≥ 1.0.0
Other optional libraries are:
- Zlib ≥ 1.2.3, for Stream Compression support (XEP-0138)
- PAM library, for Pluggable Authentication Modules (PAM)
- ImageMagick's Convert program and Ghostscript fonts, for CAPTCHA
challenges
- Elixir ≥ 1.10.3, for Elixir support. It is recommended Elixir 1.13.4 or higher
and Erlang/OTP 23.0 or higher.
If your system splits packages in libraries and development headers,
install the development packages too.
Download Source Code
--------------------
There are several ways to obtain the ejabberd source code:
- Source code archive from [ProcessOne Downloads][p1dl]
- Source code package from [ejabberd GitHub Releases][ghr]
- Latest development code from [ejabberd Git repository][gitrepo]
[p1dl]: https://www.process-one.net/download/ejabberd/
[ghr]: https://github.com/processone/ejabberd/releases
[gitrepo]: https://github.com/processone/ejabberd
Compile
-------
The general instructions to compile ejabberd are:
./configure
make
If the source code doesn't contain a `configure` script,
first of all install `autoconf` and run this to generate it:
./autogen.sh
To configure the compilation, features, install paths...
./configure --help
Install in the System
---------------------
To install ejabberd in the system, run this with system administrator rights (root user):
sudo make install
This 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/`
Build an OTP Release
--------------------
Instead of installing ejabberd in the system, you can build an OTP release
that includes all necessary to run ejabberd in a subdirectory:
./configure
make prod
Check the full list of targets:
make help
Start ejabberd
--------------
You can use the `ejabberdctl` command line administration script to
start and stop ejabberd. Some examples, depending on your installation method:
- When installed in the system:
```
ejabberdctl start
/sbin/ejabberdctl start
```
- When built an OTP production release:
```
_build/prod/rel/ejabberd/bin/ejabberdctl start
_build/prod/rel/ejabberd/bin/ejabberdctl live
```
- Start interactively without installing or building OTP release:
```
make relive
```
