Substituting your host and domain name as appropriate.
This 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, which by default is
, 'auto') to something different.
By default, registration of new users is disabled. You can either enable
registration in the config by specifying ``enable_registration: true``

For the initial alpha release, the homeserver is not speaking TLS for

Upgrading to v0.x.x
===================
Application services have had a breaking API change in this version.
They can no longer register themselves with a home server using the AS HTTP API. This
decision was made because a compromised application service with free reign to register
any regex in effect grants full read/write access to the home server if a regex of ``.*``
is used. An attack where a compromised AS re-registers itself with ``.*`` was deemed too
big of a security risk to ignore, and so the ability to register with the HS remotely has
been removed.
It has been replaced by specifying a list of application service registrations in
``homeserver.yaml``::
app_service_config_files: ["registration-01.yaml", "registration-02.yaml"]
Where ``registration-01.yaml`` looks like::
url: <String> # e.g. "https://my.application.service.com"
as_token: <String>
hs_token: <String>
sender_localpart: <String> # This is a new field which denotes the user_id localpart when using the AS token
namespaces:
users:
- exclusive: <Boolean>
regex: <String> # e.g. "@prefix_.*"
aliases:
- exclusive: <Boolean>

How to monitor Synapse metrics using Prometheus
===============================================
1: Install prometheus:
Follow instructions at http://prometheus.io/docs/introduction/install/
2: Enable synapse metrics:
Simply setting a (local) port number will enable it. Pick a port.
prometheus itself defaults to 9090, so starting just above that for
locally monitored services seems reasonable. E.g. 9092:
Add to homeserver.yaml
metrics_port: 9092
Restart synapse
3: Check out synapse-prometheus-config
https://github.com/matrix-org/synapse-prometheus-config
4: Add ``synapse.html`` and ``synapse.rules``
The ``.html`` file needs to appear in prometheus's ``consoles`` directory,
and the ``.rules`` file needs to be invoked somewhere in the main config
file. A symlink to each from the git checkout into the prometheus directory
might be easiest to ensure ``git pull`` keeps it updated.
5: Add a prometheus target for synapse
This is easiest if prometheus runs on the same machine as synapse, as it can
then just use localhost::
global: {
rule_file: "synapse.rules"
}
job: {
name: "synapse"
target_group: {
target: "http://localhost:9092/"
}
}
6: Start prometheus::
./prometheus -config.file=prometheus.conf
7: Wait a few seconds for it to start and perform the first scrape,
then visit the console:
http://server-where-prometheus-runs:9090/consoles/synapse.html
