* Add AllowEncodedSlashes to apache Add `AllowEncodedSlashes On` to apache config to support encoding for v3 rooms. "The AllowEncodedSlashes setting is not inherited by virtual hosts, and virtual hosts are used in many default Apache configurations, such as the one in Ubuntu. The workaround is to add the AllowEncodedSlashes setting inside a <VirtualHost> container (/etc/apache2/sites-available/default in Ubuntu)."

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;
|
|
}
|
|
}
|
|
|
|
* 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 hdr(host) -i matrix.example.com
|
|
use_backend matrix if matrix
|
|
|
|
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.
