|
|
|
|
|
- Source code archive from [ProcessOne Downloads][p1dl]
|
|
|
|
|
- Source code package from [ejabberd GitHub Releases][ghr]

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 --with-rebar=rebar3
|
|
|
|
|
make rel
|
|
|
|
|
|
|
|
|
|
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
|
|

|
|
|
|
|
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
|
|
|
|
|
```
|
