Matrix Synapse Miscellaneous
Different things, sometimes advanced and some things that just did not fit in the regular guide.
.well-known section
Mathijs
it's a little early, but you could also add a section about .well-known
which just means you have nginx serve a json file on example.com/.well-known/matrix/client
I did it for apache, but it's probably fairly easy for nginx as well

https://matrix.org/docs/spec/client_server/r0.4.0.html#server-discovery
if you like reading spec :)
Coturn
Coturn is a turn server and it is used for 1:1 voip calls through the client (example: riot).
apt install coturn

Add an SRV Record
To use the domain matrix.example.com
and still just use @user:example.com
instead of @user:matrix.example.com
we need to set up an SRV record. At first an A (possibly AAAA) record is needed for matrix.example.com
.
After the A record is set up, create a SRV Record that looks like
_matrix._tcp.<yourdomain.com> <ttl> IN SRV 10 0 <port> <synapse.server.name>
So, for example use
_matrix._tcp.example.com. 3600 IN SRV 10 0 8448 synapse.example.com.
and when creating the Synapse server use example.com
for the servername.
Stefan
So, when I'm using the domain matrix.example.com and want to use exmpale.com for the registration and so on, i should use SRV. If i'm using example.com and making the redirect with nginx, there is no need for a SRV record?
kythyria
The SRV record is how other servers find your server (and putting matrix federation behind a reverse proxy is a bit fragile)
Mathijs the relevant url is where the federated servers can connect to you
kythyria
It's so your server_name (what's in MXIDs) doesn't have to be the hostname of the machine synapse is running on.
Optional Adminshell
If you forgot to write sudo
and don't want to rewrite the whole command, just type sudo !!
to execute the last command with sudo rights.
There is another way but you should not work like that all the time because its not secure. There is a reason you have to write sudo
for a lot of commands. For an initial server setup you may have to type a lot of commands, to avoid typing sudo *
all the time, it is possible to type in sudo su
. This opens a admin-shell and you should be able to work without typing sudo
in. Keep in mind, exit
after step 8 and don't use sudo su
when you just have to type in some commands.

Installing Bots
Matrix Synapse currently does not have a concept of bots, a bot is just a normal user. Usally there is a config and a .py
file, download the files, unpack them and run the .py
file. Running and downloading things via pip is not recommended.
Install python3
sudo apt install python3
then install pip
sudo apt install python3-pip
then matrix-bot-api from pyp
pip3 install matrix-bot-api
and finally fill out the config and start it
python3 pollbot.py
