Using a reverse proxy with Synapse
|
|
==================================
|
|
|
|
It is recommended to put a reverse proxy such as
|
|
`nginx <https://nginx.org/en/docs/http/ngx_http_proxy_module.html>`_,
|
|
`Apache <https://httpd.apache.org/docs/current/mod/mod_proxy_http.html>`_,
|
|
`Caddy <https://caddyserver.com/docs/proxy>`_ or
|
|
`HAProxy <https://www.haproxy.org/>`_ in front of Synapse. One advantage of
|
|
doing so is that it means that you can expose the default https port (443) to
|
|
Matrix clients without needing to run Synapse with root privileges.
|
|
|
|
**NOTE**: Your reverse proxy must not 'canonicalise' or 'normalise' the
|
|
requested URI in any way (for example, by decoding ``%xx`` escapes). Beware
|
|
that Apache *will* canonicalise URIs unless you specifify ``nocanon``.
|
|
|
|
When setting up a reverse proxy, remember that Matrix clients and other Matrix
|
|
servers do not necessarily need to connect to your server via the same server
|
|
name or port. Indeed, clients will use port 443 by default, whereas servers
|
|
default to port 8448. Where these are different, we refer to the 'client port'
|
|
and the 'federation port'. See `Setting up federation
|
|
<federate.md>`_ for more details of the algorithm used for
|
|
federation connections.
|
|
|
|
Let's assume that we expect clients to connect to our server at
|
|
``https://matrix.example.com``, and other servers to connect at
|
|
``https://example.com:8448``. Here are some example configurations:
|
|
|
|
* nginx::
|
|
|
|
server {
|
|
listen 443 ssl;
|
|
listen [::]:443 ssl;
|
|
server_name matrix.example.com;
|
|
|
|
location /_matrix {
|
|
proxy_pass http://localhost:8008;
|
|
proxy_set_header X-Forwarded-For $remote_addr;
|
|
}
|
|
}
|
|
|
|
server {
|
|
listen 8448 ssl default_server;
|
|
listen [::]:8448 ssl default_server;
|
|
server_name example.com;
|
|
|
|
location / {
|
|
proxy_pass http://localhost:8008;
|
|
proxy_set_header X-Forwarded-For $remote_addr;
|
|
}
|
|
}
|
|
|
|
Do not add a `/` after the port in `proxy_pass`, otherwise nginx will canonicalise/normalise the URI.
|
|
|
|
* Caddy::
|
|
|
|
matrix.example.com {
|
|
proxy /_matrix http://localhost:8008 {
|
|
transparent
|
|
}
|
|
}
|
|
|
|
example.com:8448 {
|
|
proxy / http://localhost:8008 {
|
|
transparent
|
|
}
|
|
}
|
|
|
|
* Apache (note the ``nocanon`` options here!)::
|
|
|
|
<VirtualHost *:443>
|
|
SSLEngine on
|
|
ServerName matrix.example.com;
|
|
|
|
AllowEncodedSlashes NoDecode
|
|
ProxyPass /_matrix http://127.0.0.1:8008/_matrix nocanon
|
|
ProxyPassReverse /_matrix http://127.0.0.1:8008/_matrix
|
|
</VirtualHost>
|
|
|
|
<VirtualHost *:8448>
|
|
SSLEngine on
|
|
ServerName example.com;
|
|
|
|
AllowEncodedSlashes NoDecode
|
|
ProxyPass /_matrix http://127.0.0.1:8008/_matrix nocanon
|
|
ProxyPassReverse /_matrix http://127.0.0.1:8008/_matrix
|
|
</VirtualHost>
|
|
|
|
* HAProxy::
|
|
|
|
frontend https
|
|
bind :::443 v4v6 ssl crt /etc/ssl/haproxy/ strict-sni alpn h2,http/1.1
|
|
|
|
# Matrix client traffic
|
|
acl matrix-host hdr(host) -i matrix.example.com
|
|
acl matrix-path path_beg /_matrix
|
|
|
|
use_backend matrix if matrix-host matrix-path
|
|
|
|
frontend matrix-federation
|
|
bind :::8448 v4v6 ssl crt /etc/ssl/haproxy/synapse.pem alpn h2,http/1.1
|
|
default_backend matrix
|
|
|
|
backend matrix
|
|
server matrix 127.0.0.1:8008
|
|
|
|
You will also want to set ``bind_addresses: ['127.0.0.1']`` and ``x_forwarded: true``
|
|
for port 8008 in ``homeserver.yaml`` to ensure that client IP addresses are
|
|
recorded correctly.
|
|
|
|
Having done so, you can then use ``https://matrix.example.com`` (instead of
|
|
``https://matrix.example.com:8448``) as the "Custom server" when connecting to
|
|
Synapse from a client.
