Configuring synapse
|
||||
-------------------
|
||||
|
||||
Before you can start Synapse, you will need to generate a configuration
|
||||
file. To do this, run (in your virtualenv, as before)::
|
||||
|
||||
cd ~/.synapse
|
||||
python -m synapse.app.homeserver \
|
||||
--server-name machine.my.domain.name \
|
||||
--server-name my.domain.name \

--config-path homeserver.yaml \

--generate-config \
|
||||
--report-stats=[yes|no]
|

|
||||
...substituting your host and domain name as appropriate.
|
||||
... substituting an appropriate value for ``--server-name``. The server name
|
||||
determines the "domain" part of user-ids for users on your server: these will
|
||||
all be of the format ``@user:my.domain.name``. It also determines how other
|
||||
matrix servers will reach yours for `Federation`_. For a test configuration,
|
||||
set this to the hostname of your server. For a more production-ready setup, you
|
||||
will probably want to specify your domain (``example.com``) rather than a
|
||||
matrix-specific hostname here (in the same way that your email address is
|
||||
probably ``user@example.com`` rather than ``user@email.example.com``) - but
|
||||
doing so may require more advanced setup - see `Setting up Federation`_.

This command will generate you a config file that you can then customise, but it will
|
||||
also generate a set of keys for you. These keys will allow your Home Server to
|
||||
identify itself to other Home Servers, so don't lose or delete them. It would be
|
||||
wise to back them up somewhere safe. If, for whatever reason, you do need to
|
||||
change your Home Server's keys, you may find that other Home Servers have the
|
||||
old key cached. If you update the signing key, you should change the name of the
|
||||
key in the <server name>.signing.key file (the second word) to something different.

By default, registration of new users is disabled. You can either enable

registration in the config by specifying ``enable_registration: true`` (it is

then recommended to also set up CAPTCHA - see `<docs/CAPTCHA_SETUP.rst>`_), or
|

you can use the command line to register new users::
|
||||
The default configuration exposes two TCP ports: 8008 and 8448. Port 8008 is
|
||||
configured without TLS; it is not recommended this be exposed outside your
|
||||
local network. Port 8448 is configured to use TLS with a self-signed
|
||||
certificate. This is fine for testing with but you will almost certainly want
|
||||
to use another certificate for production purposes. You can do so by changing
|
||||
``tls_certificate_path``, ``tls_private_key_path`` and ``tls_dh_params_path``
|
||||
in ``homeserver.yaml``; alternatively, you can use a reverse-proxy, but be sure
|
||||
to read `Using a reverse proxy with Synapse`_ when doing so.

Registering a user
|
||||
------------------
|
||||
|
||||
You will need at least one user on your server in order to use a Matrix
|
||||
client. Users can be registered either `via a Matrix client`__, or via a
|
||||
commandline script.

This process uses a setting ``registration_shared_secret`` in

``homeserver.yaml``, which is shared between Synapse itself and the

``register_new_matrix_user`` script. It doesn't matter what it is (a random

value is generated by ``--generate-config``), but it should be kept secret, as

Setting up a TURN server
